Which medication should the nurse prepare for immediate administration to a child experiencing an anaphylactic reaction to a bee sting?
- A. Diphenhydramine (Benadryl)
- B. Dobutamine (Dobutarex)
- C. Epinephrine (Adrenalin)
- D. Calcium chloride (calcium chloride)
Correct Answer: C
Rationale: After the first priority of establishing an airway, administration of epinephrine is the drug of choice. Diphenhydramine, an antihistamine, is usually not used for severe reactions. Dobutamine and calcium chloride are not appropriate drugs for this type of reaction.

A client with chronic kidney disease (CKD) arrives at the clinic reporting shortness of breath on exertion and extreme weakness. Vital signs are temperature 100.4°F (38°C), heart rate 110 beats/minute, respirations 28 breaths/minute, and blood pressure 175/98 mmHg.
