7. Which statement is true of Duchenne MD? a. Usually the result of trauma b. Progressive and causes crippling and immobility c. Affects males and females equally d. Is not a genetic condition

ANS: B

MD is a progressive degeneration and weakening of the skeletal muscles in which muscle fibers are abnormally vulnerable to injury. There are several types of the disease, but all are rare. The most common and best-known type is Duchenne MD, which is diagnosed soon after birth or during early childhood, usually before the age of 5 years. MD initially affects the muscles of the shoulders, hips, thighs, and calves of the legs, causing the characteristic waddling gait and toe walking. Affected muscles sometimes look larger than normal because fat replaces atrophied muscle. The child also may have lordosis or other spinal deformities. In addition, the child has difficulty climbing stairs and running, tends to fall easily, and has difficulty getting up. As the disease progresses, it involves all the muscles, causing crippling and immobility (see Fig. 2.13). Contractures typically develop, and the child becomes increasingly susceptible to serious pulmonary infections such as pneumonia. Also, children with Duchenne MD often are impaired mentally.

12. Which statement(s) is/are true about asthma? a. The bronchial tubes are hyperactive and hypersensitive. b. Severe attacks require hospitalization. c. It is a leading cause of absenteeism in school children. d. All of the answer options are true.

ANS: D

Asthma is the result of hyperactive and hypersensitive bronchial tubes. The bronchial spasms of asthma can be triggered by many extrinsic (allergic) or intrinsic (nonallergic) factors, including stress, heavy exercise, infection, and inhalation of allergens or other substances. In a severe attack unresponsive to drug therapy, a condition called status asthmaticus may lead to fatal respiratory failure and thus the need for endotracheal intubation. The patient requires hospitalization for aggressive medical treatment and follow-up. Asthma is a chronic, reversible, obstructive disease caused by increased reactivity of the tracheobronchial tree to various stimuli. There are two major processes at work: constriction of the bronchioles and inflammation of the airway. It is a leading cause of chronic illness and school absenteeism in children.

Down syndrome, in addition to mild to severe intellectual developmental disorder, is associated with heart defects and other congenital abnormalities. Typically the infant has a small head; a skull with a flat back; a characteristic slant to the eyes; a flat nasal bridge; small, low-set ears; a small mouth with a protruding tongue; and small, weak muscles (see Figs. 2.10 and 2.11). The hands are short with stubby fingers and a deep horizontal crease across the palm (simian line). There is an exaggerated space between the big and little toes. Infants with Down syndrome have an extra chromosome number 21 (trisomy 21). It occurs in 1 in 650 live births and more often in infants born to women more than 35 years of age (see Fig. 2.12).

Infants with severe Down syndrome usually are identified at or before birth; milder forms are diagnosed later. The physical characteristics may be blatantly obvious. Findings on examination of the eyes may include the presence of small white dots on the iris. A karyotype showing the chromosomal abnormality can confirm the diagnosis.

The cause of erythroblastosis fetalis is Rh factor incompatibility. Rh factor is the antigen found on RBCs of the Rh-positive individual. The mother, through a prior pregnancy, has become sensitized to the Rh factor (Rh isoimmunization) of the fetal RBCs. When sensitized maternal blood finds its way into fetal circulation, particularly during delivery, the antibodies in the mother’s blood destroy the RBCs of the fetus (see Figs. 2.48 and 2.49). If an Rh-negative woman has children with an Rh-positive man, some or all of the infants will be Rh positive. During pregnancy, blood from the Rh-positive fetus may move from fetal circulation into the mother’s bloodstream, where it can stimulate the mother’s body to form antibodies against the Rh factor. When sufficient quantities of the antibodies pass back into the infant’s circulation, the antibodies can clump and destroy Rh-positive cells, causing the symptoms of erythroblastosis fetalis. Erythroblastosis fetalis is characterized by anemia, jaundice, kernicterus, and enlargement of the liver and spleen. In the most severe form, called hydrops fetalis, the fetus or infant is in great jeopardy because of extreme hemolysis. If the infant survives, the condition is marked by heart failure, edema, pulmonary congestion, lethargy, seizures, and intellectual developmental disorder.

30. Pregnant women should be isolated from individuals infected with _________ to prevent

perinatal infection. a. rubeola b. rubella c. chickenpox d. diphtheria ANS: B

Rubella causes great danger to the unborn children of pregnant women who contract the disease. Women of child-bearing age who have not been immunized against rubella or who have not had the disease can transmit rubella to their infants if they become infected during pregnancy. When the virus is transferred to the fetus during the first trimester of pregnancy, a variety of congenital deformities, known as congenital rubella syndrome, occur in about 25% of births. The risk is lower if infection occurs later in pregnancy. Anomalies caused by congenital rubella syndrome include congenital cardiac disease, blindness, deafness, and intellectual developmental disorder. Pregnant women should be isolated from individuals infected with rubella to prevent perinatal infection; in addition, pregnant women must not be given the rubella vaccine. The best protection against congenital rubella syndrome is universal routine immunization with live rubella vaccine during infancy or as soon as possible in adulthood.

34. Causes of prematurity include which factors? a. Incompetent cervix, bicornuate uterus, and premature rupture of membranes b. Maternal physical conditions including infection and hypertension c. Multiple gestation d. All of the answer options ANS: D

There are many reasons that infants enter the world before reaching the traditionally accepted gestational age of 40 weeks and thus have very low birth weights. Causes of premature labor resulting in a premature infant are an incompetent cervix, bicornuate uterus, toxic conditions, maternal infection, trauma, premature rupture of the amniotic membranes, history of previous miscarriages, multiple gestations, intrauterine fetal growth developmental disorder, and other physical conditions of the mother, such as pregnancy-induced or chronic hypertension.

Diabetes, heart disease, kidney disease, poor nutrition, substance abuse, and lack of prenatal care also contribute to the incidence of the mother giving birth to a preterm infant. In some cases, the etiology is never identified. Attempts may be made to halt premature labor by having the mother on complete bed rest or using drug therapy to slow or halt contractions. The mother is often given a short course of steroids to aid fetal lung maturation. Many times the efforts to allow the fetus more time to grow and mature in the mother’s uterus are unsuccessful.

35. Which conditions often result from premature birth? a. NEC, IRDS, and ROP

b. Spina bifida, hydrocephalus, and anencephaly c. MD, CF, and Down syndrome d. All of the answer options ANS: A

NEC, IRDS, and ROP often result from premature birth, despite advances in technology which result in survival of low-weight and short-gestation infants possible. The prognosis for these children varies depending on gestational age, weight, and the occurrence of anomalies and developmental deficits. There are documented cases of 12-ounce and/or 22-gestational-week babies surviving. They fall into the 1% of premature babies born at that weight and gestational age. Being born before the normal prenatal development is complete, these children often have many problems to overcome (see Fig. 2.5). A primary risk is a cerebral bleed, which may occur during the labor and delivery process or may result from handling after delivery. The cerebral bleed may cause the development of CP, mental functioning deficiencies, or other neurologic conditions. Another major concern is underdevelopment of the pulmonary system, including the lung tissue and the airway. Some pulmonary conditions these infants experience are IRDS, bronchopulmonary dysplasia, laryngomalacia, tracheomalacia, and bronchomalacia. Lack of body fat can affect the maintenance of body temperature. Any stress or increased or high supplemental O2 flow may be responsible for ROP and possible blindness. NEC is a danger in the digestive system because of the reduced tolerance of the alimentary tract. ASD and PDA often are present because the fetal circulatory system has failed to mature.

36. At which areas of the body may twins be conjoined? a. Head to head (cranial). b. Posteriorly at the sacrum and coccyx c. Chest to chest d. All of the answer options ANS: D

Conjoined twins may be joined at different locations of the body and may share various organs. The attachment to each other may involve a small portion of tissue or may be as extensive as fusion at the head or sharing of an organ or body part. Common types or variations usually are categorized by the location and involvement of the junction through the term pagus, meaning fastened, included in the classification terminology. Twins with a cranial union are considered to be craniopagus. Those with anterior junction at the chest, often sharing the heart and vital portions of the chest wall and internal organs, are called thoracopagus conjoined twins. Thoracopagus is the most common form of conjoined twins.

The term pygopagus describes those twins who are joined posteriorly at the rump. Another posterior junction occurring at the sacrum and coccyx is termed ischiopagus. When the connection proceeds from the breastbone to the waist, the term omphalopagus describes the junction. A very rare form, dicephalus, is the condition in which the individual has one body and two separate heads and necks.

11. Closure of PDA may be achieved by medication or by surgical closure of the ductus.

ANS: T

PDA results when the ductus fails to functionally close. During normal fetal circulation, the patent ductus short circuits shunting the circulation from the lungs and instead directs blood from the pulmonary trunk to the aorta. If PDA continues after birth, circulation of oxygen is compromised because this abnormal opening is a shunt that allows oxygenated blood to recirculate through the lungs (see Fig. 2.22). PDA is detected during a physical examination when a classic ―machinery‖ murmur is heard on auscultation and palpitation reveals a thrill.

The infant’s growth and development may be slowed, and various signs of heart failure may be present. Closure may be attempted by drug therapy using an antiprostaglandin or ibuprofen. The other option is surgical closure of the ductus.

16. Neural tube defects include spina bifida occulta, meningocele, and myelomeningocele.

ANS: T

Spina bifida is a group of malformations of the spine in which the posterior portion of the bony canal containing the spinal cord (usually in the lumbar region) is completely or partially absent (see Fig. 2.14A). Also called neural tube defects, the three different levels of the condition originate during early weeks of gestation as the spinal cord and bony canal develop.

During this developmental stage, there is a failure of the posterior spinal processes to close, usually in the lumbar region. This failure of complete closure allows the meninges and, in severe cases, the spinal cord to herniate. Depending on the extent of the herniation and the amount of the neural tube that has herniated, various degrees of neural deficits or impairment occur. The three types of spina bifida are spinal bifida occulta, meningocele, and myelomeningocele.

22. During fetal circulation, blood bypasses the lungs.

ANS: T

Because the fetal lungs are not functioning, this blood mostly bypasses the lungs. Most of the blood entering the right atrium by the inferior vena cava is shunted directly into the left atrium through the foramen ovale. There is a small valve on the left side of the atrial septum called the septum primum. This valve keeps blood from going back into the right atrium. The remaining fetal blood that has entered the right atrium contains a large amount of oxygen-poor blood from the superior vena cava and travels to the right ventricle and into the pulmonary trunk. The pulmonary blood vessels have a high resistance to blood flow because of the collapsed state of the lungs; thus they only allow a small amount of blood to enter the pulmonary circulation. This small amount is enough to nourish the pulmonary tissue.

10. Which statement is true about chronic open-angle glaucoma? a. Caused by a decrease in intraocular pressure (IOP) b. Produces symptoms at the onset c. Rarely progresses d. Most treatable cause of blindness ANS: D

Chronic open-angle glaucoma, a silent disease, is the most common form of glaucoma and is the most treatable cause of blindness. Patients can have open-angle glaucoma for a significant period of time before symptoms appear. By the time symptoms do appear, considerable damage usually has occurred. If chronic open-angle glaucoma goes untreated, the patient experiences characteristic loss of vision. The central vision may remain clear for a considerable period of time. However, if the condition progresses, the central vision is also lost, causing complete blindness. The best way to detect glaucoma is by having periodic routine ophthalmic examinations, which include IOP readings and optic nerve evaluations.

22. Ankylosing of the stapes is called a. Ménière’s disease. b. otomycosis. c. otosclerosis. d. exotropia.

ANS: C

Otosclerosis, an abnormal bone growth in the middle ear, primarily affects the stapes, the third bone or ossicle of the middle ear, as the individual ages. Movement of the ossicles is impaired, which causes diminished conduction of sound waves and resulting hearing loss (see Fig. 5.30). With this condition, an abnormal growth of spongy bone forms around the oval window, causing ankylosis of the stapes. Ankylosis produces conductive deafness because the ossicles cannot conduct the sound vibrations as they enter the ear. Symptoms of otosclerosis are tinnitus and a gradual hearing loss of low or soft sounds, which may be unilateral at first, but usually affects both ears at some point. Patients usually report not being able to hear as well with the affected ear when talking on the telephone. Relatives may notice that patients turn their heads to hear well. Otosclerosis is a young person’s disease, with onset usually beginning after puberty and before 35 years of age.

30. Labyrinthitis is an inflammation of the a. stapes. b. conjunctiva. c. semicircular canal. d. tympanic membrane.

ANS: C

Labyrinthitis is an inflammation or infection of the labyrinth of the inner ear. The inner ear contains two membrane-lined chambers, each filled with fluid, called the cochlea and the labyrinth. The cochlea contains tiny hairs that change the sound waves in the fluid into nerve impulses, which then are transmitted to the brain via the auditory nerve. The labyrinth is responsible for maintaining balance. It consists of three connected tubes bent into half circles, called the semicircular canals. Their function is to detect movement of the head and relay this information to the brain.

TRUE/FALSE 1. The only treatment that cures otosclerosis is a surgical procedure called stapedectomy.

ANS: T

The only treatment that cures otosclerosis is a surgical procedure called a stapedectomy. A stapedectomy involves the removal of the diseased stapes and replacement with a prosthesis.

The composition of the prosthesis may be metal or a ceramic or plastic material. Use of a ceramic or plastic is likely because these materials facilitate visualization by MRI for the purpose of diagnosing and because of the inability to perform an accurate test of the patient’s hearing if the prosthesis is made of metal. If the condition is bilateral, only one ear is operated on at a time so the success of the procedure can be evaluated. Generally hearing improves soon after the surgery. A recent procedure, a stapedotomy, is performed with a laser creating a hole in the stapes permitting placement of a prosthetic device. If surgery is not an option for the patient, a hearing aid can be tried.

2. The middle ear is normally air-filled.

ANS: T

The middle section of the ear is filled with air and contains the tympanic membrane and three ossicles (tiny bones) called the malleus (hammer), the incus (anvil), and the stapes (stirrup).

Also in the middle ear is a canal, called the eustachian tube, which leads to a cavity (the pharynx) at the back of the nose. At the innermost region of the middle ear is the oval window, the opening to the inner ear. The middle ear receives the sound waves from the vibrating eardrum and relays them along the three bones to the oval window (see Fig. 5.19).

OBJ: 9

3. Serous otitis media may be either acute or chronic.

ANS: T

Serous otitis media may be either acute or chronic. With acute serous otitis media (see Fig. 5.24), the cause is usually a virus from an upper respiratory infection that has spread through the eustachian tube into the middle ear. It can occur spontaneously or may result from an allergic reaction. Chronic otitis media (see Fig. 5.25) can develop from an acute attack, hypertrophy of the adenoids, or chronic sinus infections. Suppurative otitis media (see Fig. 5.26) is caused by bacteria, which also can enter the middle ear through the eustachian tube from the nose or throat or from a ruptured tympanic membrane. This condition often follows a bout of influenza or mumps. Variations in the normal structure of the eustachian tube can predispose a person to this disease. Oftentimes an allergic response is responsible for swelling of the eustachian tube and the resulting otitis media.

8. Blepharoptosis can be ectropion or entropion.

ANS: F

Blepharoptosis, also called ptosis, is a permanent drooping of the upper eyelid, such that it partially or completely covers the eye. Blepharoptosis usually affects one eye, but both can be involved. In the case of entropion, the eyelid margins (more often the margin of just the lower lid) turn inward, causing the lashes to rub the conjunctiva. Ectropion is a condition in which the lower eyelid everts from the eyeball, and the exposed surface of the eyeball and the lining of the eyelid become dry and irritated.

The major risk of a ruptured eardrum is that an infection may develop in the middle ear.

Symptoms of a ruptured tympanic membrane (eardrum) are usually slight pain and partial loss of hearing and may include a slight discharge or bleeding from the ear. Buzzing in the ear and/or facial weakness or dizziness may be experienced. When an infectious process is involved, the drainage is usually purulent in nature. These symptoms may last only a few hours.

12. A cholesteatoma and mastoiditis can both be the result of a neglected otitis media.

ANS: T

A cholesteatoma and mastoiditis can be caused from neglected otitis media. This condition often begins to develop in infancy or it may be the result of chronic ear infection. The eustachian tube from the middle ear to the pharynx either fails to open properly or becomes blocked with material from recurring middle ear infections (see ―otitis media‖ section). As a result, this normally air-filled chamber develops a weak vacuum, causing the eardrum to become retracted. This forms the pocket in the eardrum that allows the cholesteatoma to develop. Acute mastoiditis is the result of neglected acute otitis media. Streptococcus is the usual causative organism, but certain pneumococci and Staphylococcus aureus may also be involved. Chronic mastoiditis, necessitating radical or modified radical mastoidectomy, is associated with cholesteatoma.

16. The labyrinth is responsible for maintaining balance.

ANS: T

The inner ear contains two membrane-lined chambers, each filled with fluid, called the cochlea and the labyrinth. The cochlea contains tiny hairs that change the sound waves in the fluid into nerve impulses, which then are transmitted to the brain via the auditory nerve. The labyrinth is responsible for maintaining balance. It consists of three connected tubes bent into half circles, called the semicircular canals. Their function is to detect movement of the head and relay this information to the brain.

The cause of acne vulgaris is unknown; however, research links it to hormonal changes of adolescence that affect the activity of the sebaceous glands. Hereditary tendencies are also known to be predisposing factors. Precipitating factors may include food allergies, endocrine disorders, psychologic factors, fatigue, and the use of steroid drugs. Sebum, an oily substance produced by the sebaceous glands, reaches skin surface through the hair follicle.

Overproduction of the oil seems to stimulate the follicle walls, causing a faster shedding of skin cells. This causes the cells and sebum to stick together and form a plug, which promotes the growth of bacteria in the follicles. This is the process by which pimples and nodules form.

Valvular heart disease is an acquired or congenital disorder that can involve any of the four valves of the heart. This condition can occur in the form of either insufficiency or stenosis.

Insufficiency, the failure of the valves to close completely, allows blood to be forced back into the previous chamber as the heart contracts. This exerts added pressure on that chamber and increases the heart’s workload. Stenosis, a hardening of the cusps of the valves that prevents complete opening of the valves, impedes the blood flow into the next chamber.

OBJ: 19

15. Possible consequences of emboli include a. cerebral vascular accident (CVA). b. MI. c. pulmonary venous obstruction. d. All of the answer options ANS: D

Emboli are clots of aggregated material (usually blood). They can lodge in blood vessels and inhibit blood flow. Treatment depends on the area of involvement. Treatment of pulmonary embolism MI, and CVA is aggressive and immediate if the patient is to survive. The treatment of a patient with arterial emboli in an extremity is also aggressive and immediate to prevent the death of tissue and eventual gangrene. Blood flow is reestablished to the affected part by lowering the limb, wrapping it to maintain warmth to the area, and treating any constriction of blood vessels. Heparin or enoxaparin [Lovenox] are administered to deter further clot formation, and antispasmodic drugs are given for vascular spasms. If this therapy is not successful, surgical intervention may be indicated to remove the obstruction and to restore circulation. In another option, a thrombolytic drug (such as urokinase, tissue plasminogen activator, tenecteplase, alteplase, reteplase, or streptokinase) can be administered via a central catheter directly into the spot of the coronary embolism to breakdown the emboli. The prognosis varies and depends on the location of the emboli. When the emboli are in an extremity, aggressive treatment and/or surgical intervention usually are successful.

16. Which condition is present when the patient has a pulsating mass that is noted mid-abdomen? a. An arrhythmia b. Palpitations c. Aortic aneurysm d. Pulmonary embolus ANS: C

The symptoms of an aneurysm may have either an insidious or a sudden, acute onset.

Symptoms depend on the location and size of the aneurysm and the extent of the dilation.

Abdominal aortic aneurysm is the most common form. An asymptomatic aneurysm of the aorta is often discovered during a routine physical examination when the abdomen is being palpated or as the result of an abdominal radiographic study conducted for another reason. As the aortic aneurysm enlarges, the patient may experience abdominal or back pain, and a pulsating mass is observed in the abdomen. A complication of any aneurysm is leakage from the wall of the artery or sudden rupture of the weak area. When this occurs, the patient exhibits symptoms and signs of hemorrhagic shock. Rupture of a cerebral aneurysm mimics signs of a CVA, with unilateral neurologic deficits being noted.

anemia. a. sickle cell b. hemolytic c. pernicious d. aplastic ANS: A

Sickle cell anemia, a chronic hereditary hemolytic form of anemia, is found predominately in those of the black race. The presence of Hgb S along with Hgb A is noted in erythrocytes, causing them to acquire a sickle or elongated shape on deoxygenation. These rigid, misshapen cells obstruct capillary flow and lead to tissue hypoxia and further sickling; this in turn causes further obstruction and eventually infarction. When the sickling causes an obstruction, the individual experiences severe pain. When the sickled cells are reoxygenated, they resume the natural round disk shape of a normal erythrocyte. In addition, Hgb S has reduced oxygen-carrying capacity.

40. The two upper chambers of the heart are the a. atria. b. septa. c. ventricles. d. valves.

ANS: A

The heart consists of two side-by-side pumps, each divided into two chambers: two upper chambers called atria, and two lower chambers called ventricles. As venous blood returns to the heart from the body, it enters the right atrium, passes through the tricuspid valve, and with atrial contraction, enters the right ventricle. Heart valves prevent the blood from flowing backward. From the right ventricle, blood is pumped through the pulmonary valve and, with ventricular contraction, into the pulmonary arteries and on to the lungs. In the lungs, carbon dioxide is removed and oxygen is added to the blood. Freshly oxygenated blood then returns to the heart via the pulmonary veins. It enters the left atrium, moves through the mitral (bicuspid) valve with atrial contraction, and enters the left ventricle. As the left ventricle contracts, the blood is forced through the aortic valve, into the aorta, and on to the rest of the body. This process is called the cardiac cycle.

REF: p. 382

TRUE/FALSE 1. Lithotripsy is a procedure used to examine the urinary tract.

ANS: F

Lithotripsy is a procedure used to destroy renal calculi which are also called kidney stones.

Treatment for kidney stones begins with analgesic therapy and hydration during the initial evaluation. Location and size of the calculi indicate the course of treatment. Small calculi (<5 mm) may be treated by observation and with fluid hydration in the hope that the stone will pass spontaneously. Large calculi can be removed by any of several surgical procedures.

Attempts are made to crush stones that are (1) too large to pass down the ureter, (2) lodged in the pelvis of the kidney, or (3) trapped in the proximal portion of the ureter. ESWL is a procedure that breaks apart (crushes) the stones, thus allowing the small particles to flush out of the body naturally. A surgical procedure using an ureteroscope to capture the stone in a basket and remove it is attempted for stones trapped in the distal aspect of a ureter. If the attempt to capture the stone is unsuccessful, EHL or laser lithotripsy is used in an attempt to break the stone apart into small particles that can be flushed out of the system.

lead to renal failure.

ANS: T

CGN is a slowly progressive, noninfectious disease that can lead to irreversible renal damage and renal failure. As an advanced stage of many kidney disorders, CGN results in inflammation followed by progressive destruction of the glomeruli. This progressive destruction causes a reduction in glomerular filtration with resulting retention of uremic poisons.

REF: p. 454

OBJ: 5

4. ARF is a clinical emergency.

ANS: T

ARF, a sudden and severe reduction in renal function, is a common clinical emergency because nitrogenous waste products begin to accumulate in the blood quickly, thereby causing an acute uremic episode.

6. Symptoms of renal calculi are the same regardless of the size of the stone.

ANS: F

The symptoms of renal calculi vary according to the size of the stone. Kidney stones can be solitary or multiple and vary in size. A larger stone formed in the shape of the renal pelvis is known as a staghorn calculus. Small stones can be passed spontaneously unnoticed. The patient’s symptoms vary with the degree of obstruction. If infection or blockage caused by the calculi are present, the patient experiences sudden severe pain in the flank area, known as renal colic, with urinary urgency and other urinary symptoms. Other symptoms include nausea and vomiting, hematuria, fever, chills, and abdominal distention. Blood in the urine can be the result of trauma caused by the presence of small stones, which may be gravel-like in consistency, or larger stones, such as staghorn calculi. Hydronephrosis can develop if urine is prevented from flowing past the calculi.

REF: p. 465

OBJ: 13

7. Hydronephrosis is caused by decreased blood flow to the kidney.

ANS: F

Hydronephrosis is an abnormal dilation of the renal pelvis caused by pressure from urine that cannot flow past an obstruction in the urinary tract.

12. Which symptoms and signs indicate toxemia in pregnancy, preeclampsia, and eclampsia? a. Hypertension, edema, protein in the urine, and convulsions. b. Hypotension and other indications of shock. c. Symptoms that mimic pregnancy. d. None of the answer options above.

ANS: A

Hypertension, edema, protein in the urine and convulsions are signs of toxemia in pregnancy, preeclampsia, and eclampsia. Preeclampsia can be preceded by increased weight gain.

Elevation of blood pressure to a level >140/90 is a sign. When there is >300 mg of protein in the urine over a 24-hour period, then the conditions for the diagnosis of preeclampsia are present. If the patient has a seizure, it is usually of the grand mal variety, and they can have the usual postictal manifestation of confusion and disorientation. These patients are also at increased risk for stroke, and thus any symptom of a central neurologic nature may need to be evaluated for the presence of stroke.

19. Which treatment/s are used for anxiety disorders? a. Drug therapy b. Hypnosis c. Stress elimination d. All of the answer options

ANS: D

Drug therapy, hypnosis, and stress elimination are all methods of treating anxiety. If the anxiety prevents the person from living a normal life, a psychiatrist or a practitioner trained in treating psychologic problems (e.g., psychologist or psychoanalyst) should be consulted.

Hypnosis is sometimes used to help the patient and the therapist to gain access to the subconscious mind. If the anxiety is caused by a specific stress (e.g., job related), steps should be taken to minimize or eliminate the problem. Various methods of relaxation such as systematic desensitization, progressive relaxation, breathing exercises, and guided imagery can lessen the symptoms. Relaxation exercises (e.g., biofeedback) to relax tense muscles or a physical activity, such as brisk walking, jogging, or swimming, may be beneficial. In addition, or as an alternative, the physician may prescribe an anxiolytic drug. Serotonin-specific reuptake inhibitors (SSRIs) (fluvoxamine [Luvox] is U.S. Food and Drug Administration approved for treatment of OCD) are first-line therapy, but many patients with major depression also may have been prescribed a tricyclic amitriptyline/nortriptyline along with the SSRI and recommended psychotherapy. Benzodiazepines are also frequently prescribed.

Examples are lorazepam [Ativan], clonazepam [Klonopin], and alprazolam [Xanax].

20. The phases of the grief process are a. denial, anger, bargaining, depression, and acceptance. b. not identifiable. c. depression, bargaining, anger, and denial. d. anger, denial, rejection, and acceptance.

ANS: A

The normal grieving process passes through several phases. The most recognized stages are those identified by Elisabeth Kübler-Ross. The first is denial: ―No, I don’t believe it.‖ Second is anger: ―Why did he or she do this to me?‖ or ―Why is God letting this happen?‖ The third stage is bargaining: ―If only this task can be accomplished or I can achieve this goal (live long enough), I will do this.‖ Fourth is depression, in which people retreat within themselves and have little or no involvement with their environment. Finally, in the fifth stage, acceptance comes. Not everyone is able to move through these steps, and not everyone moves through them at the same pace or in the same order. Some people cannot express anger at the dead person or at God and do not move on. Many of these people never complete the grieving process, so they remain in a depressed state and have reduced coping mechanisms. Medical intervention may help during depression, but most people recover with minimal treatment.
