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

Answer and Explanation

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 D

Explanation

A. Spinal cord degeneration is a general term for the deterioration of the spinal cord and doesn't specifically describe the patient's posture.
B. Decorticate posturing is characterized by the arms flexed and adducted, with the wrists and fingers flexed. The legs are extended and adducted, with the feet plantar flexed.
C. Atypical hyperreflexia refers to exaggerated reflexes, not a specific posture.

D. Decerebrate posturing is characterized by the arms extended and pronated, with the wrists and fingers flexed. The legs are stiffly extended with plantar flexion.

A. Heart rate 160/min B. Hypokalemia C. Mottled skin D. Blood pressure 115/68 mmHg

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.
