Heparin acts by binding to antithrombin III (AT III, a protein), which greatly increases AT III’s ability to inhibit the action of coagulation factors thrombin, Xa, and IXa. Binding with AT III enables heparin to work at several points in the clotting cascade by inhibiting factor X, interfering with prothrombin-to-thrombin conversion, and inactivating thrombin, thus preventing of fibrinogen-to-fibrin conversion. Heparin also interferes with platelet aggregation and the formation of a stable fibrin clot.

ANS: A

Ophthalmic lubricants may be used when a general anesthetic is administered for any surgical procedure. With patients under general anesthesia, eyelids are relaxed, and the corneal reflex is absent. To prevent corneal drying or damage and maintain integrity of the epithelial surface, a nonionic ointment or lubricant, such as lanolin alcohol (Lacri-Lube) or polyvinyl alcohol (Liquifilm, Lubrifresh), is applied to each eye. Then the eyelids are taped closed or special foam eye masks with plastic shields are used.

Etomidate (Amidate) is a hypnotic agent that is often used for patients with compromised myocardial contractility who cannot tolerate the myocardial depression often observed with other induction agents. It is particularly useful for induction in patients with trauma who may be hypovolemic and therefore unable to tolerate any additional hypotension.

Which group of drugs is given to facilitate intubation, as well as provide better surgical exposure during abdominal procedures? a. Opioids b. Muscle relaxants c. Tranquilizers d. Analgesics ANS: B

Agents categorized as neuromuscular blockers are administered to relax skeletal muscles for intubation and surgery. Patients under general anesthesia may be unconscious, pain free, and memory free, but their skeletal muscles continue to respond to stimuli. To receive an ET tube, the patient must be adequately relaxed—that is, the muscles must be relaxed. During some surgical procedures, especially in the abdomen, the patient’s muscles must be relaxed to facilitate exposure of the surgical site.

42. What is the neurotransmitter that is released at neuromuscular synapses to stimulate the release of calcium ions? a. Acetylcholine antagonists b. Acetylcholinesterase c. Acetylcholine d. Succinylcholine ANS: C

The neurotransmitter at the neuromuscular junction is acetylcholine (ACH). When ACh is released from the axon, it diffuses across the synapse (synaptic cleft) and binds to receptor sites on the cell membrane of the muscle fiber (sarcolemma). Acetylcholine causes a wave of depolarization to spread across the muscle fiber to T-tubules, which conduct the wave of depolarization deep into the muscle fibers. As a result of the spreading wave of depolarization, calcium is released from its storage sites within the sarcoplasmic reticulum.

ANS: A

If additional help is not available (as seen when performing emergency on-call procedures), it may become necessary for the scrubbed surgical technologist to break scrub and help reconstitute dantrolene as directed by the anesthesia provider, but surgical technologists are not authorized to administer medications.

18. In a hemolytic transfusion reaction, which agent would be used to treat hypotension? a. Mannitol b. Benadryl c. Epinephrine d. Dopamine ANS: D

Hemolytic transfusion reactions are first treated by discontinuation of blood products, followed by control of hypotension.

Medications used to raise blood pressure (vasopressors and/or inotropic agents) are administered as needed. Vasopressor agents include dopamine and phenylephrine.

ANS: D

The first-line pharmacologic treatment for cardiac arrest (also known as asystole—the absence of a heart beat) is epinephrine.

Epinephrine is a hormone (see Chapter 8) that acts as a vasopressor (causes vasoconstriction and raises blood pressure) and inotrope to strengthen the force and rate of myocardial contractions (to improve coronary perfusion pressure and myocardial blood flow).
