A nurse is caring for a client who is experiencing anaphylactic shock in response to the administration of penicillin. Which of the following medications should the nurse administer first?
Methylprednisolone
Dobutamine
Furosemide
Epinephrine
The Correct Answer is D
Methylprednisolone is a crucial medication in managing anaphylaxis but it takes longer to act compared to epinephrine and is not the immediate first-line treatment.
B. Dobutamine is a vasopressor used to treat heart failure. However, it's not indicated in the initial management of anaphylaxis.
C. Furosemide is a diuretic used for conditions like heart failure and edema. It has no role in treating anaphylaxis.
D. Epinephrine is the first-line treatment for anaphylactic shock. It rapidly reverses the life-threatening effects of anaphylaxis by constricting blood vessels, relaxing airway muscles, and stimulating the heart.

Correct Answer is A
Explanation
A. Tachycardia is a classic sign of the compensatory stage of shock. The body attempts to increase cardiac output by increasing heart rate to maintain blood pressure.
B. Hypokalemia is more likely to occur in the later stages of shock, as it's associated with tissue breakdown and renal dysfunction.
C. Mottled skin is a sign of the progressive stage of shock, indicating poor peripheral perfusion.
D. Blood pressure 115/68 mmHg: While this might be considered within normal range, it's important to consider the baseline blood pressure of the patient. In the compensatory stage, blood pressure may be maintained, but there are other compensatory mechanisms in place (like increased heart rate) to do so.
Correct Answer is C
Explanation
A. amiodarone is a medication used to treat ventricular fibrillation administered after defibrillation.
B. Epinephrine is also used in cardiac arrest, but it is administered after unsuccessful defibrillation attempts.
C. Defibrillation is the immediate life-saving intervention for ventricular fibrillation. It delivers a high- energy shock to the heart to try to restore normal rhythm.
D. While important in cardiac arrest, it is not the immediate priority. Defibrillation takes precedence.
