Certified Ambulatory Perianesthesia Nurse (CAPA) Practice Exam

In the event of acute anaphylactic shock, what is the anticipated medication a perianesthesia nurse should prepare to administer after initiating oxygen?

1. Gastric acid blockers and epinephrine

2. Steroids and dobutamine

3. Norepinephrine and fluids

4. Colloids and beta-blockers

The correct answer is: Gastric acid blockers and epinephrine

In the event of acute anaphylactic shock, the administration of epinephrine is a critical, life-saving intervention. Epinephrine works by causing vasoconstriction, increasing heart rate, and improving myocardial contractility, all of which help to counteract the severe hypotension and inadequate perfusion that can occur during anaphylaxis. Additionally, it helps to relax the bronchial smooth muscle, alleviating respiratory distress. Gastric acid blockers may also be considered in a broader context of medical management, particularly if there is concern for stress ulcers after acute events; however, they do not address the immediate life-threatening aspects of anaphylaxis. The primary goal during such an emergency is to respond rapidly with epinephrine, which is recognized as the first-line treatment. Other combinations of medications, such as steroids and dobutamine, norepinephrine and fluids, or colloids and beta-blockers, are generally not the immediate focus in the context of anaphylactic shock. Steroids are typically used for longer-term management and may take hours to exert their effects, while dobutamine is not a standard treatment for anaphylaxis. Similarly, norepinephrine and fluids may be used in treating septic or cardiogenic shock, not specifically
