The patient is receiving zolpidem (Ambien) for treatment of short-term insomnia. What is the primary safety concern of the nurse when the patient takes this medication?

Correct Answer: A

Rationale: Zolpidem, a sedative-hypnotic, causes dizziness and daytime sedation-fall risks, especially if not sleeping fully, per safety data. Nausea and diarrhea occur but aren't primary. Sleepwalking is rare, notable but less common. Sedation drives monitoring, a key concern.

Correct Answer: D

Rationale: Nasal decongestants risk rebound beyond 5 days; spitting excess avoids systemic effects (correct answers: 1, 3, 5). Water isn't relevant. D ensures safe use, making it key.

Correct Answer: C

Rationale: Central venous access devices (CVADs) are advantageous for chemotherapy administration because they allow caustic or vesicant drugs to be delivered directly into larger veins, reducing the risk of vein irritation, thrombosis, or extravasation. While CVADs may have other benefits, such as long-term use and reduced need for repeated IV insertions, their primary advantage in chemotherapy is the safe administration of potentially damaging agents. Home administration and cost are secondary considerations.

Correct Answer: D

Rationale: Terfenadine is a second-generation antihistamine, but it is not an H1 receptor antagonist like the other options listed. Terfenadine was once used for the treatment of allergic conditions, but it is known for its potential to cause cardiac side effects due to its interaction with other medications and prolongation of the QT interval. Consequently, terfenadine has been largely replaced by newer, safer antihistamines. The rest of the options listed (chlorpheniramine, promethazine, cimetidine, and diphenhydramine) are all H1 receptor antagonists commonly used to block the action of histamine and relieve symptoms of allergies.

Correct Answer: B

Rationale: Meperidine hydrochloride (Demerol) is an opioid analgesic commonly used for post-operative pain management. The common side effects of meperidine include tremors, sweating, and dizziness. Diarrhea is not a common side effect associated with meperidine use. Opioid analgesics like meperidine more commonly cause constipation rather than diarrhea. Therefore, choice B is the correct answer as the side effect of diarrhea is not typically seen with meperidine administration.
