One hour after receiving intravenous morphine sulfate, a patient reports generalized itching. The nurse assesses the patient and notes clear breath sounds, no rash, respirations of 14 breaths per minute, a heart rate of 68 beats per minute, and a blood pressure of 110/70 mm Hg. Which action will the nurse take?

Correct Answer: D

Rationale: The correct action for the nurse to take in this situation is to prepare an epinephrine injection in case of an anaphylactic reaction. The patient's presentation of generalized itching could be a sign of an allergic reaction to morphine sulfate. It is important to be prepared for an anaphylactic reaction, which could potentially be life-threatening. Having epinephrine readily available allows for quick administration if needed to treat the allergic reaction. Reassuring the patient is also appropriate, but the priority in this situation is to be prepared for a possible serious allergic reaction. Administering naloxone to reverse opioid overdose is not indicated based on the patient's current vital signs and symptoms. Having resuscitation equipment available at the bedside is always a good practice, but preparing for an anaphylactic reaction takes precedence in this scenario.

Correct Answer: A

Rationale: Benzodiazepines (e.g., lorazepam) rapidly calm via GABA, making them highly effective for acute anxiety and insomnia, per clinical use. They carry dependence risk-not low. Insurance or cost varies, not unique. Effectiveness drives preference, despite risks, for quick relief.

Correct Answer: A

Rationale: Patients with peptic ulcers should stop taking NSAIDs (Nonsteroidal Anti-Inflammatory Drugs) because NSAIDs can worsen the condition and increase the risk of gastrointestinal bleeding and ulcer perforation. NSAIDs inhibit prostaglandin synthesis, which normally helps protect the stomach lining. Therefore, patients with peptic ulcers should avoid NSAIDs and consult their healthcare provider for alternative pain management options.

Correct Answer: C

Rationale: Physostigmine, a cholinesterase inhibitor, lowers IOP in glaucoma by increasing aqueous outflow . It contracts the ciliary muscle, opening the trabecular meshwork. Secretion or synthesis reduction isn't its mechanism. Raising pressure (D, E) contradicts its use. This aids drainage in open-angle glaucoma.

Correct Answer: B

Rationale: Individual variation-metabolism, weight, genetics-dictates dose differences, a pharmacokinetic truth explaining her higher amount. Female metabolism isn't universally higher. Hormones affect response, but not broadly dose. Body fat impacts distribution, not directly dose here. Uniqueness covers all factors, reassuring and accurate.
