A nurse is caring for a client with a new diagnosis of hypertension.
Which of the following medications is used to treat hypertension? (Select All That Apply.)

Choice A rationale

Morphine has a high potential for abuse due to its euphoric effects and the risk of developing physical dependence and addiction with prolonged use.

Choice B rationale

Morphine acts as an agonist on the mu and kappa receptors in the central nervous system, providing analgesic effects by altering the perception of and response to pain.

Choice C rationale

Morphine is a potent analgesic that is more effective than butorphanol, which is a mixed agonist-antagonist with less potency and a ceiling effect on pain relief.

Choice D rationale

Morphine is primarily used for pain management and is not indicated for preventing fevers.

Choice A rationale

Azithromycin can prolong the QT interval, leading to potential cardiac arrhythmias. Patients with a history of prolonged QT interval or other heart conditions should be monitored closely.

Choice B rationale

Constipation is not commonly associated with azithromycin use. Gastrointestinal side effects may include diarrhea or nausea but not constipation.

Choice C rationale

While tachycardia can be a side effect of some medications, azithromycin is more commonly associated with QT prolongation rather than causing increased heart rate directly.

Choice D rationale

Hyperkalemia is not typically a concern with azithromycin. Electrolyte imbalances are not a common side effect of this antibiotic.
