Right before I went under to have surgery on my septum… I was about to start counting backwards before they put the mask on.

Answers and Rationale

Here are the answers for this exam. Gauge your performance by counter checking your answers to those below. If you have any disputes or clarifications, please direct them to the comments section.

1. Answer: A. halothane (Fluothane)

Arrhythmias are a result of an interaction that can occur with halothane and catecholamines. Other choices do not interact with halothane to cause arrhythmias.

2. Answer: B. Skeletal muscle relaxants

The effects of skeletal muscle relaxants are potentiated with the use of the general anesthetics. Depolarizing agents do not interact with general anesthetics. C and D are general anesthetics.

3. Answer: B. Hyperthermia

Malignant hyperthermia is the most dangerous metabolic side effect of general anesthesia.

4. Answer: D. Expect nausea, vomiting, shivering, and pain postoperatively.

These responses should be expected, and the client should be prepared for them. Food is contraindicated before surgery. Urinary retention, not incontinence is likely. Medication is more likely to be held on the day of surgery.

5. Answer: A. Inhibiting depolarization.

When local anesthesia is used, sensation is removed and the area anesthetized by inhibition of depolarization. Choice B is incorrect because the opposite is true. Choices C and D do not occur with local anesthesia.

6. Answer: B. Shivering can occur in the absence of hypothermia.

Shivering can also appear after surgery. This is known as postanesthetic shivering.

7. Answer: D. Hypertension

Manifestations of local anesthetic toxicity typically appear 1-5 minutes after the injection, but onset may range from 30 seconds to as long as 60 minutes. Initial manifestations may also vary widely. Classically, patients experience symptoms of central nervous system (CNS) excitement such as the following: Circumoral and/or tongue numbness, metallic taste, lightheadedness, dizziness, visual and auditory disturbances (difficulty focusing and tinnitus), disorientation and drowsiness.

8. Answer: B. bradycardia.

Atropine, an anticholinergic drug, is used as an adjunct to anesthesia to counter the effects of vagal stimulation, which is caused by surgical manipulations that trigger parasympathetic reflexes, resulting in bradycardia. Atropine is not an anxiolytic. Atropine causes dry mouth and sometimes is used to minimize bronchial secretions.

9. Answer: B. Emergence delirium

Emergence delirium could occur postoperatively, and is characterized by hallucinations, confusion, and excitability.

10. Answer: A. Return of the gag reflex

Because the throat is anesthetized, monitor the client for return of the gag reflex before drinking or eating.

11. Answer: D. Prevent the administration, and give a plain lidocaine solution.

Solutions of lidocaine containing preservatives or epinephrine are intended for local anesthesia only, and must never be given IV for dysrhythmias.

12. Answer: B. An intravenous drug will be given to calm the client.

Stage 2 is the stage of excitement and hyperactivity. Medications may be given IV to calm the client.

13. Answer: D. Respiratory status.

General anesthesia causes relaxation of all muscles, including respiratory muscles, requiring mechanical ventilation. The client’s respiratory status must be monitored closely following general anesthesia.

14. Answer: C. “Vasoconstrictors should not be used as adjunct agents with this drug.”

Cocaine should not be combined with epinephrine or other vasoconstrictors, because it causes vasoconstriction itself, and the combination could precipitate severe hypertension. Cocaine has a rapid onset of effects, which last about 1 hour. It is used only topically for anesthesia. Although subject to widespread abuse with profound psychological dependence, it does not cause substantial physical dependence.

15. Answer: B. Blocks a specific group of nerves in tissues close to the operative area.

Infiltration anesthesia blocks a specific group of nerves close to the operative area by diffusion of a drug into the tissues. It is used to anesthetize small areas. Topical anesthetics are applied to mucous membranes. Nerve blocks provide anesthesia to a large surface area. Spinal anesthesia affects large, regional areas.

16. Answer: A. Stimulating opiate receptors

It is the stimulation of cerebral opiate receptors that reduces pain. Excitatory transmitters are not released during administration of morphine. Endorphin release is not associated with narcotic pain relief. The mu receptors mediate analgesia and are not blocked during narcotic administration.

17. Answer: B. Euphoria, miosis, nausea and vomiting

These are the effects that often occur with administration of narcotics. Constipation (not diarrhea) and decreased respirations (not increased) are noted during administration of narcotics. Decreased blood pressure results from narcotic administration. Narcotics do not cause the effects in choice D at all.

18. Answer: B. 2 to 4 hours

The half-life of morphine is 2 to 4 hours. Other choices are incorrect because they are either longer or shorter than the true half-life of morphine.

19. Answer: D. Morphine quickly enters all body tissues.

Morphine quickly enters all body tissues. Morphine is not contraindicated for head-injured clients, and withdrawal symptoms can be relieved by methadone. Morphine is equally effective by all routes when the proper dose is prescribed.

20. Answer: C. Codeine is very constipating

Codeine is very constipating, so the client’s diet should include foods that fight constipation, such as water, fruits, and vegetables.
