Which prescription should the nurse clarify with the provider prior to administration?

Potassium Chloride 20 mEq PO daily.

HCTZ 25 mg PO daily.

Amlodipine 10 mg PO daily.

Clonidine 1 mg PO TID PRN for systolic blood pressure of 180.

Answer and Explanation

The Correct Answer is D

Choice A rationale

Potassium chloride 20 mEq daily is a common dose for hypokalemia prevention or treatment. Normal serum potassium is 3.5–5.0 mEq/L. This dose is unlikely to cause adverse effects without significant hyperkalemia.

Choice B rationale

Hydrochlorothiazide 25 mg daily effectively manages hypertension by reducing fluid retention. It can cause hypokalemia; thus, monitoring serum potassium is crucial. Normal serum potassium range is 3.5–5.0 mEq/L.

Choice C rationale

Amlodipine 10 mg daily is a standard antihypertensive dose. It is a calcium channel blocker that dilates blood vessels, lowering blood pressure without significant adverse effects in most patients.

Choice D rationale

Clonidine 1 mg TID PRN for systolic blood pressure above 180 is excessive. Normal doses are 0.1–0.3 mg. High doses risk severe hypotension, bradycardia, and withdrawal symptoms. This requires clarification.

Correct Answer is A

Explanation

Choice A rationale: An oxygen saturation of 84% indicates severe hypoxemia. Normal oxygen saturation levels are between 95% and 100%. A level this low can impair tissue oxygenation and lead to life-threatening complications like respiratory failure or cardiac arrest.

Choice B rationale: An elevated blood pressure of 168/90 mm Hg, while concerning, does not immediately signify a life-threatening condition. It can be a result of distress or pain and needs management but is not as critical as severe hypoxemia.

Choice C rationale: A respiratory rate of 27/min is elevated but not immediately life-threatening. It indicates the body's effort to compensate for hypoxemia, but the underlying issue of low oxygen saturation is more critical to address.

Choice D rationale: A heart rate of 98/min, although increased, does not indicate a life-threatening condition. The elevation may be due to distress or medication side effects. Managing hypoxemia is more urgent to prevent further complications.

A. Orange slices. B. Ground hamburger. C. Cooked green beans. D. Canned peaches.

Correct Answer is A

Explanation

Choice A rationale

Orange slices pose a choking risk due to their firm texture and fibrous membranes, making them inappropriate for a mechanical soft diet.

Choice B rationale

Ground hamburger has a soft consistency and is easily chewable, meeting the requirements of a mechanical soft diet.

Choice C rationale

Cooked green beans are soft and easy to chew, aligning with the dietary restrictions of a mechanical soft diet.

Choice D rationale

Canned peaches are soft and can be mashed easily, making them suitable for a mechanical soft diet.
