Answer Key Checkpoint Questions/Think It Through LO 1.1

Checkpoint Questions 1. Cardiovascular disease 2. Willem Einthoven LO 1.2 Think It Through: Remain Calm Say: “The physician would like me to do a recording of your heart.” Do not show signs of fear or anxiety. Remain calm during the procedure.

Checkpoint Questions 1. Sudden cardiac arrest caused by ventricular tachycardia and ventricular fibrillation.

2. Records the ECG tracing, determines if the ECG tracing is accurate and without abnormalities caused by interference during the recording procedure, and prepares the tracing for the physician’s interpretation.

LO 1.3 Think It Through: Obtaining Consent A family member, legal representative, or witness, but the patient should write an X if possible.

Checkpoint Question 1. Answers will vary; an example is provided here.

Step 1: Identify and define the problem: You have been assigned to perform an ECG, and the patient refuses.

Step 2: Identify possible solutions: a. Do not perform the ECG. b. Insist that the patient allow you to perform the ECG. c. Report the patient to your supervisor. d. Question the patient as to why she does not want the ECG and attempt to gain her cooperation.

Step 3: Select the best solution: d. Question the patient as to why she does not want the ECG and attempt to remove her objection.

Step 4: Implement the selected solution: You question the patient, and she feels uncomfortable about lying exposed on the table during the procedure. You tell her you will cover her and maintain her privacy to the best of your Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

Step 6: There is no need to return to step 2 because the problem is solved.

LO 1.4

Checkpoint Questions 1. Follow standard precautions and, when necessary, the appropriate isolation precautions.

2. Airborne precautions require special air handling, ventilation, and HEPA or N95 respirator; Droplet precautions requires goggles and masks; Contact precautions require gloves and gowns.

LO 1.5

Checkpoint Questions 1. Pulse, respirations, and blood pressure.

2. Palpated blood pressure is performed by applying the blood pressure cuff to the patient's arm, then placing the fingers on the radial pulse point and inflating the blood pressure cuff. When the pulse disappears, you continue to inflate the cuff an additional 30 mm/Hg, then begin to deflate the cuff slowly in 5mm intervals. When the pulse returns it is an approximation of the systolic blood pressure. Auscultated blood pressure is determined using a stethoscope and provides a more accurate systolic and diastolic blood pressure reading.

Critical Thinking Application: What Should You Do? 33. (LO 1.3) Your favorite uncle should have an ECG as part of a routine physical since he is over 40; however, the physician should order this. You should not perform an ECG on someone without a verbal or written order from an authorized healthcare provider. You may, however, practice an ECG on someone, as long as the individual understands you are not going to interpret it or use it for diagnosis. This must be done with the approval of your supervisor. Question 31 in the text.

34. (LO 1.3) “Mr. Smith, I am not trained to interpret the results of your ECG. As soon as the physician sees it, I am sure he or she will discuss the results with you. How are you feeling right now? Are you having any discomfort or pain? How would you rate your pain on a scale of 1-10, with 0 being no pain and 10 being the most pain?”

35. (LO 1.3) Every patient has the right to privacy. Your co-worker may have just forgotten to close the door and /or drape the patient. You could quietly close the Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

door or curtain in order to provide for privacy. It would be best not to make any statement or comment to your co-worker at this time unless he or she asks.

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

36. (LO 1.3) You should tell your supervisor how you feel and explain the need to go to the restroom. Do not leave the monitors unattended except for extreme or severe circumstances. You should find someone to view the monitors when you are not there. You have a legal and ethical responsibility to ensure that someone is watching the monitors when you are not there. Hopefully, your supervisor will be able to find someone to take your place in order for you to go home.

Voyage through the Heart (LO 2.3) 36. a. Superior vena cava. b. Tricuspid valve. c. Pulmonary veins. d. Left atrium. e. Coronary arteries.

Critical Thinking Application: What Should You Do? 37. (LO 2.5) The atrioventricular (AV) node is responsible for slowing the electrical conduction from the atria to the ventricles (acting like a “gatekeeper”). This delay in electrical conduction prevents some of the electrical impulses from stimulating the ventricles and allows the atria to fully contract ejecting blood into the ventricles.

38. (LO 2.5) The sympathetic branch of the autonomic nervous system responded to the stress from the darkness and sound and increased your and your patient’s and your heart rates. Without further stimulation, your patient’s heart rate will return to normal. It would be best to wait for a while until the patient’s heart rate is within normal limits before recording the ECG.

Teaching Strategies Introduce students to “The Electrocardiograph” using the following techniques: 1. Bring to the lab equipment that students can practice placing on each other or a manikin. Equipment should include the ECG electrodes, electrode gel or paste, lead wires, paper, and an ECG machine.

2. Provide each student with ECG paper. Each student should identify how the singlechannel and multi-channel paper are different. Have students identify the components of time and measurement of energy (0.04 second box, 0.20 second box).

3. Since students are often intimidated by math, you may try relating the ECG paper measurements to counting money. Follow these steps. − Write 0.04 on the board or in a PowerPoint® presentation. Then discuss and establish that 0.04 equals four cents. − Ask students to tell you how many stacks of 4 cents will be needed to add up Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

to 20 cents. Once it is established that the answer is 5, show the following.

0.04 cent ×5 cent 0.20

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

− Next, remove the cents and add a dollar sign in front of the 0.04 and 0.20 and show the following.

$ 0.04 ×5 $ 0.20 − Remind students that $0.20 equals two dimes, and ask students how many dimes it would take for 20 cents to become a dollar. Then show the following.

$ 0.04 ×5 $ 0.20 ×5 $1.00 − Tell students we are going to make one small change, then add seconds behind the 0.04, 0.20 and 1.00 and remove the dollar signs and show the following.

0.04 seconds ×5 0.20 seconds ×5 1.00 second − At this point, students should make the connection between money and the ECG paper. You can use this as a foundation to demonstrate how we get to 300 large boxes by multiplying 60 seconds by 5 large boxes per second, then multiplying 300 by 5 small boxes per large box to get to 1500.

4. Demonstrate how the ECG machine creates different views of the heart. Using a heart model, have two students or objects represent the + and – electrodes. Move them around the heart to help students visualize the different views of the heart.

Critical Thinking Application: What Should You Do? 52. (LO 3.5) The machine is about to run out of paper. You should change the paper before performing the next ECG. 53. (LO 3.4) ECG electrodes dry out. Check to see if the bag has been properly sealed. If so, you may use them if they do not appear to be dried out. Otherwise, it is best to use new electrodes. If you attempt to use the electrodes after you determine they have been properly sealed but you have difficulty with the tracing, you still may need to replace them.

54. (LO 3.1) You have probably attached the lead wires incorrectly. Check each lead color and make sure the leads are properly placed. Since you cannot read the letters, refer to the manufacturer’s directions to identify the correct color for each lead wire.

55. (LO 3.3) Make sure the machine is standardized if that is required of the machine you are using. Check the LCD display. The machine may identify the problem for you. In addition, check the attachment to the patient…skin prep, sensors, then check the cable clips…are they attached to the cables properly and are they grasping the sensors as intended, are they clean without gel buildup. Check the cables themselves…ensure there is no damage to them and that they are inserted into the clips and hub appropriately. Always work from the patient all the way back to the machine. Use the lead selector to repeat the entire 12-lead ECG procedure.

In general, you should be familiar with the controls of the machine you are using.

Review the manufacturer’s directions carefully.

audiovisuals. If a representative is not available, a previous student or someone who performs ECGs on a regular basis would be a good choice to provide a demonstration.

2. Discuss the different HIPAA violations that may occur when performing a 12-lead ECG. During this discussion, identify ways to ensure that these violations are prevented. For example, protection of the patient’s name, where ECGs are placed, and what students would do if a friend asked about the results.

3. Have students practice on a manikin as the first step in performing a 12-lead ECG tracing. Ensure that the electrodes are placed on the body properly. During this time, have students troubleshoot what they would do in unusual situations; for example: patient with Parkinson’s disease, amputation, cast or splinted arm/leg, mastectomy, or obese patient.

4. Place each of the steps of performing an ECG on a card. Give one card to each student. Then have students organize themselves into the correct order of the procedure.

5. Have students work in pairs to perform a 12-lead ECG on one another. They can use Competency Checklist 4-1, Performing an ECG, for reference. This allows students to provide privacy while performing the ECG and offers them the opportunity to obtain their own 12-lead ECG. Ensure that this practice is not a violation of student policy and/or HIPAA requirements.

6. After completion of student practice, each student should demonstrate how to properly clean and store the equipment.

7. Discuss the importance of properly stocking the 12-lead ECG machine and have each student practice changing the ECG paper.

8. On a student who is willing to have his chest exposed, demonstrate what happens when ECG electrodes have dried out. Emphasize the importance of not leaving a package of ECG electrodes open or having the electrodes connected prior to performing the ECG.

Introduce students to “Rhythm Strip Interpretation” using the following techniques: Have students identify components of P, Q, R, S, T, and U waves on a variety of rhythm strips. The rhythm strips should be obtained in different lead selections to have QRS complexes with both positive and negative deflections.

Discuss how the QRS complex still represents the ventricular depolarization regardless of whether the QRS complex has a positive or negative deflection.

Have students discuss or role-play the actual mechanical movement of the heart during each of the P, Q, R, S, and T waves.

Review the steps in “Identifying the Components of the Rhythms” by dividing the class into five groups, one for each of the steps. Have each group review the step and present it to the class by discussing what the step involves and also by demonstrating how to perform that step on an ECG strip.

In pairs, have students demonstrate how to identify each component of an ECG tracing to one another.

Critical Thinking Application: What Should You Do? 19.

(LO 5.2) The process of determining the type of cardiac dysrhythmia can be challenging. The best approach in determining the actual rhythm is to take on the role of a detective. Detectives gather all the information they can before determining who is the suspect or how something has happened. The process of ECG analysis is similar. First you gather all the data regarding the different waveforms and their patterns. The next step is to match all the information to the specific ECG rhythm criteria in order to classify the various cardiac dysrhythmias.

Teaching Strategies Introduce students to “Sinus Rhythms” using the following techniques: 1. Divide the class into five groups, one for each dysrhythmia discussed in the chapter. Have each group review one of the dysrhythmias and present it to the class, discussing its distinguishing characteristics and presenting examples of ECG strips that show the rhythm.

2. In pairs, have students demonstrate how to identify the components of each sinus rhythms on an ECG tracing.

3. Search the Internet or other resources for various ECG strips representing different dysrhythmias. Certain ECG machines can print abnormal strips as examples.

Provide practice sessions by passing the strips around or projecting them in class and reviewing each one. Start by just differentiating the different strips. First introduce the easiest strips; then introduce more complex strips with each practice session.

4. Play a matching game by having students match the unique feature with each rhythm identified in the book. You can do this in presentation format or by creating index cards for each feature.

Teaching Strategies Introduce students to “Junctional Dysrhythmias” using the following techniques: 1. Divide the class into five groups, one for each dysrhythmia discussed in the chapter. Have each group review one dysrhythmia and present it to the class, discussing its distinguishing characteristics and presenting examples of ECG strips that show the rhythm.

2. In pairs, have students demonstrate how to identify the components of each junctional dysrhythmia on an ECG tracing.

3. Search the Internet or other resources for various ECG strips representing different junctional dysrhythmias. Certain ECG machines can print abnormal strips as examples. Provide practice sessions by passing the strips around or projecting them in class and reviewing each one.

4. Play a matching game by having the students match the unique features with each junctional dysrhythmia identified in the book. You can do this in presentation format or by creating index cards for each feature.

Answer Key Checkpoint Questions/Think It Through LO 8.1

Checkpoint Question 1. With junctional rhythms, electrical impulses are coming from the AV node instead of the SA node. These electrical impulses cause depolarization of the atria to flow retrograde, or backward. This reverse flow of electrical activity causes the inverted P wave.

LO 8.2

Checkpoint Question 1. B; note the “inverted” P wave on the early complexes.

LO 8.3

Checkpoint Questions 1. A; note the inverted waves.

2. Junctional rhythm has a rate between 40 and 60 bpm. A PJC rate is based on the underlying rhythm combined with the number of PJCs. The P-P and R-R intervals in junctional rhythms are regular. PJCs are premature, interrupting the cadence of the underlying rhythm and causing it to be irregular.

LO 8.4

Checkpoint Question 1. A; note the missing P waves, normal QRS, and rate between 60 to 100 beats per minute.

LO 8.5

Checkpoint Question 1. B; note the inverted P waves after the QRS complex and rate in excess of 100 bpm LO 8.6

Checkpoint Questions 1. Greater than 150 bpm. Electrical impulses or the loci of stimulation come from above the ventricles.

Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A. Booth, Thomas Edward O'Brien All Chapters 1-15

2. The practitioner might ask you to increase the paper speed in an effort to expose the P waves and analyze the tracing more carefully.

3. Racing, fluttering, “not feeling right,” dizziness, “heart racing in my chest”

Short Answer 10.

(LO 8.1) Where the Electrical impulses are generated from in the junctional tissue region of the heart will determine where the P wave is located (before, during or after the QRS complex). The P wave is inverted due to backward (retrograde) depolarization of the atria. The coordination of the P and QRS complex has to do with the locus of stimulation within the AV junction causing depolarization of the atria and ventricles.

Answer Key Checkpoint Questions/Think It Through LO 9.1

Checkpoint Question 1. The electrical current has difficulty traveling down the normal conduction pathway.

LO 9.2

Checkpoint Question 1. B; PR interval greater than 0.20 second LO 9.3

Checkpoint Question 1. A; prolonging PR interval, missing QRS, then prolonging PR interval pattern starts over.

LO 9.4

Think It Through: Mobitz I vs. Mobitz II For a Mobitz I (Wenckebach), the PR interval in front of the dropped QRS complex will be longer than the PR interval after the dropped QRS complex. Type I has a cyclical pattern of prolonging PR intervals, then a dropped QRS complex. lengthen, lengthen drop…

Checkpoint Question 1 A; Missing QRS complexes; wherever a P wave is with a QRS complex, the PR interval always measures the same.

LO 9.5

Checkpoint Question 1. B; regular P-P and R-R intervals but firing at different rates. Variable PR interval, some P waves buried within QRS complexes or T waves

Short Answer 11.

(LO 9.2–9.5) First degree, second degree type I (Wenckebach), second degree type II, and third degree (complete) heart block. Third degree is most serious, due to atria and ventricles being electrically separated (dissociated) from one another.

12.

(LO 9.3, 9.4) In Mobitz I, PR interval is in a progressively prolonging pattern followed by a missing QRS, then the pattern resets and starts over again.

In Mobitz II has missing QRS complexes, but wherever a P wave is with the QRS complex, the PR interval will always measure the same.

13.

(LO 9.5) Always check the patient first! Watch for signs of low cardiac output. The patient may be unconscious. Contact the practitioner by calling a code. This patient may need to be treated with medication, pacemaker, or both, depending upon the patient’s ability to tolerate the rhythm. Rhythm strips are always obtained, labeled, and placed in the patient’s medical record.

Answer Key Checkpoint Questions/Think It Through LO 11.1

Checkpoint Questions 1. Atrial pacing is used alone when the conduction system from the atrioventricular node through the ventricles is intact and functioning.

2. The atrioventricular pacing option mimics the normal cardiac conduction system and allows the atria to contract completely prior to the ventricles, which allows for an atrial kick.

3. A rate-responsive pacemaker is one that monitors the sinus node rate, breathing, and blood temperature and can adjust the pacing speed to speed up or slow down the heart based on the metabolic demands of the body.

Teaching Strategies Introduce students to “Cardiac Stress Testing” using the following techniques: 1. Briefly review how exercise affects the heart and cardiovascular system.

Compare and contrast maximal and submaximal exercise and when each is used.

Discuss the basic formula followed for each, as shown below.

Note: Current technology automatically calculates THR once the patient’s date of birth is entered into the stress test monitor as part of the software program. This does not relieve the technician of the responsibility for double-checking the number and knowing the appropriate formula based upon testing protocol and facility policy.

2. Have students figure their own target heart rate based on their age and a variety of common multipliers (such as .60, .75, and .85).

Calculating Target Heart Rate (THR) Standard Exercise (Maximal Heart Rate) 220 – age = heart rate 220 – 20 = 200 bpm Exercise Stress Testing (220 – age) × .85 = heart rate (220 – 46) × .85 = 174 × .85 = 147.9 bpm or 148

Based on a 20-year old

Based on a 46-year old

3. Arrange for a representative from one of the ECG equipment companies or another healthcare professional to visit your class and discuss cardiac stress testing.

The company representative may bring printed information or other audiovisuals. If a representative is not available, a previous student or someone who performs ECGs on a regular basis would be a good choice to initiate a discussion.

4. Arrange a trip to a local healthcare facility that performs cardiac stress testing. If possible, have students view the equipment and watch an exercise electrocardiography test in progress.

5. Have students role-play a variety of scenarios, such as patient instruction, communication to gain cooperation, and troubleshooting.

6. Have students complete “Cardiac Crossword Chapter 12” and review the answers in class.

before the procedure is repeated. Follow the guidelines at your place of employment.

Critical Thinking Application: What Would You Do? 36.

(LO 13.6) Monitors are expensive and easily damaged. The first thing you should do is examine the monitor for obvious cracks or breaks. If you do not find any damage, insert the batteries and test to see if it functions properly. If it does not work, you may need to contact the manufacturer for repair. Most importantly, you should report the incident to your supervisor and use a different monitor for ambulatory monitoring while the original monitor is being serviced.

37.

(LO 13.7) It appears that your patient was not given the proper instructions, did not understand the instructions, or was unable or unwilling to write in the diary.

You can question the patient to see if he or she remembers some of the activities during the 24- to 48-hour period and attempt to fill in the blanks. You would need to make note of this on the diary. You may want to show the physician or your supervisor the diary to determine if the monitoring should be repeated or continued. It may be wise to do this prior to removing the monitor, in case the physician decides to continue the monitoring. Most importantly, if the monitoring is going to occur again, you should ensure that the patient understands and is able to complete the diary. Proper patient education is important. You may also be able to enlist the help of a family member if the patient is unable or unwilling to complete the diary.

38.

(LO 13.4) For some reason, Mr. Hernandez is not willing to complete the diary. Try to understand his reason by discussing it with him. Ask him questions to gain a better understanding of the problem. He may be illiterate, not understand English or just be uncooperative. In either case, you will need to enlist the cooperation of a family member to ensure that the diary is complete. Ambulatory monitoring will not be effective unless the patient completes the diary.

39.

(LO 13.7) When the ambulatory monitor is in place, the patient is instructed to avoid magnets, metal detectors, high-voltage areas, and electric blankets. At most courthouses, all individuals are required to walk through a metal detector. Ms. Lin should call the courthouse in advance to determine if alternate screening arrangements can be made. If not, consult with the physician to see if the monitoring can be delayed until after Ms. Lin’s court appearance.

Checkpoint Questions 1.

When the left pump fails, it causes blood to back up into the right heart, which in turn causes right heart failure. When the left pump (ventricle) fails, blood will stall and back up in the lungs, often causing pulmonary edema. Respiratory assessment will often reveal noisy, “wet”-sounding lungs, referred to as rales (crackles). Additional signs and symptoms of left heart failure include: • Shortness of breath or trouble breathing • Fatigue (tiredness) • Tachycardia Instructor Solutions Manual Electrocardiography for Healthcare Professionals 6th Edition by Kathryn A.

Checkpoint Questions 1.

Assess the pain level; check the vital signs, including pulse oximetry, start oxygen at 4 liters/min; obtain 12-lead ECG immediately and with each set of vital signs; notify the physician or treating practitioner of a patient with chest pain; practitioner interprets the ECG. 2.

These mnemonics help ensure that you approach all cardiac patients in the same way and that your assessment of each patient is complete and thorough.

LO 14.7

Checkpoint Questions 1.

Clot busters are used to prevent or break down clots. Thrombolytic agents convert plasminogen to plasmin which in turn breaks down the fibrin that is in a clot. Fibrinolytic agents destroys the fibrin in a clot. Fibrin is necessary for a clot to form.

2.

Stents are placed during coronary angioplasty to help keep the coronary artery open.

Answer Key Checkpoint Questions/Think It Through LO 15.1

Checkpoint Question 1.

In order to view either the right ventricle or the posterior wall of the heart; also for dextrocardic patients.

LO 15.2

Checkpoint Questions 1.

Wandering baseline makes it difficult to analyze the ST segment. This could give the appearance of ST elevation or depression when this is not the case or may allow the interpreter to miss ST elevation or depression.

2.

Low oxygen level to a region of cells in the heart that occurs when there is a reduction or interruption in blood flow and oxygen to the myocardium.

3.

ST segment elevation.

4.

Two or more views looking at the same part of the heart, or two numerically consecutive chest leads.

5.

A Q wave that measures 0.04 second or greater in width and/or greater than or equal to 1/3 the height of the R wave in that lead.

LO 15.3

Checkpoint Questions 1. Electricity will flow as it normally does down the unaffected side; the affected side will depolarize in a cell-by-cell manner, causing the QRS complex to widen and reflecting the longer depolarization period. If both ventricles are blocked, the patient could possibly end up with a complete heart block (medical emergency).

2. RBBB—Electricity passes down the left bundle as it normally does; the right bundle is blocked, causing a cell-by-cell depolarization. Electrical evidence on a 12lead would be viewed best in lead V1. There will still be a P wave, but the ventricular depolarization will measure 0.12 second or greater and the QRS is positively deflected.

LBBB—Electricity passes down the right bundle as it normally does; the left bundle is blocked, causing a cell-by-cell depolarization. Electrical evidence on a 12-lead would be viewed best in lead V1. There will still be a P wave, but the ventricular depolarization will measure 0.12 second or greater and the QRS is negatively deflected.

(LO 15.4) In a bundle branch block (the) duration or width of the QRS is increased on the tracing. With hypertrophy, the amplitude or voltage of the QRS is affected increased.

41.

(LO 15.4) Evidence of atrial activity (P wave). Remember, the problem is within the ventricles, so we must see a P wave to tell us that the electrical activity was initiated above the ventricles. QRS complex that measures 0.12 second or more in duration.

42.

(LO 15.4) Presence of atrial activity. If the majority of ventricular depolarization is negative or a QS complex is present measuring greater than 0.12 seconds, it is an LBBB. 43.
