A nurse is caring for a client who has urticaria following administration of an antibiotic. Which of the following medications should the nurse prepare to administer?
Diphenhydramine
Hydralazine
Naloxone
Protamine
The Correct Answer is A
A. Diphenhydramine. Urticaria (hives) is a common allergic reaction often caused by medications like antibiotics. Diphenhydramine, an antihistamine, is used to treat allergic reactions by blocking histamine receptors, reducing itching, swelling, and rash.
B. Hydralazine. This is an antihypertensive medication used to treat high blood pressure, not allergic reactions. It has no effect on histamine or allergic symptoms.
C. Naloxone. Naloxone is an opioid antagonist used to reverse opioid overdose. It does not treat allergic reactions like urticaria unless the cause is opioid-induced (which is not indicated here).
D. Protamine. Protamine is used to reverse the effects of heparin. It has no role in treating allergic reactions to antibiotics.

Correct Answer is B
Explanation
A. A client who has a fracture and is in balance suspension traction. This client is non-ambulatory and difficult to move quickly, so should not be evacuated first unless they are in immediate danger. They would require additional assistance and equipment to move safely.
B. A client who is ambulatory and receiving oxygen. This client is able to walk independently and can evacuate with minimal assistance, even while on oxygen. Evacuating ambulatory clients first helps clear the area quickly and frees up staff to assist less mobile clients.
C. A client who uses a wheelchair and is confused. While this client needs help due to confusion and mobility limitations, they are not the priority for first evacuation unless in immediate danger. They require more time and assistance.
D. A client who is bedridden and wears a hearing aid. This client is non-ambulatory and may have communication challenges, which makes evacuation more complex. They would be evacuated after ambulatory clients for safety and efficiency.
Correct Answer is C
Explanation
A. Ketorolac. This is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of gastrointestinal bleeding, especially in clients with a history of peptic ulcer disease. It should be avoided in this population.
B. Aspirin. Aspirin is also an NSAID and can irritate the gastric lining, increasing the risk of ulceration and bleeding. It is contraindicated in clients with peptic ulcers.
C. Acetaminophen. Acetaminophen is the safest option for clients with peptic ulcer disease because it does not affect the gastric mucosa. It provides effective relief for mild to moderate pain, including headaches.
D. Ibuprofen. Like ketorolac and aspirin, ibuprofen is an NSAID and is not recommended for clients with peptic ulcers due to the increased risk of gastrointestinal irritation and bleeding.
