A nurse is caring for a client who is to receive potassium replacement. The provider’s prescription reads, “Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min.” For which of the following reasons should the nurse clarify this prescription with the provider?

The potassium infusion rate is too rapid.

Another formulation of potassium should be given IV.

Potassium chloride should be diluted in dextrose 5% in water.

The client should be treated by giving potassium by IV bolus.

Answer and Explanation

The Correct Answer is A

According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.

Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.

Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.

Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.

Correct Answer is D

Explanation

Drowsiness is a very common adverse effect of paroxetine, a selective serotonin reuptake inhibitor (SSRI) used to treat depression and anxiety. Paroxetine can cause somnolence (sleepiness) in up to 22% of patients who take it. The nurse should instruct the client to monitor for this effect and avoid driving or operating machinery until they know how the medication affects them.

Choice A is wrong because tinnitus (ringing in the ears) is not a common adverse effect of paroxetine.

It may occur rarely in some patients, but it is not a typical symptom of SSRI use.

Choice B is wrong because alopecia (hair loss) is not a common adverse effect of paroxetine.

It may occur rarely in some patients, but it is not a typical symptom of SSRI use.

Choice C is wrong because peripheral edema (swelling of the limbs) is not a common adverse effect of paroxetine.

It may occur rarely in some patients, but it is not a typical symptom of SSRI use.

A. Take one tablet each morning 30 minutes prior to eating. B. Discard any tablets you do not use every 6 months. C. Keep the tablets at room temperature in their original glass bottle. D. Place the tablet between your cheek and gum to dissolve.

Correct Answer is C

Explanation

The correct answer is choice C. Keep the tablets at room temperature in their original glass bottle. Rationales: Choice A rationale: Taking one tablet each morning 30 minutes prior to eating is incorrect. Sublingual nitroglycerin is used to relieve acute angina attacks and is taken as needed rather than on a fixed schedule. Choice B rationale: Discarding any tablets not used every 6 months is incorrect. Sublingual nitroglycerin tablets should be replaced every 6 months to ensure potency, but this is not the main teaching point for safe storage. Choice C rationale: Keeping the tablets at room temperature in their original glass bottle is correct. Nitroglycerin tablets are sensitive to light and moisture, and the original glass bottle protects them from these elements, ensuring their effectiveness. Choice D rationale: Placing the tablet between the cheek and gum to dissolve is incorrect. Sublingual nitroglycerin tablets should be placed under the tongue where they dissolve and are absorbed quickly into the bloodstream for rapid relief of angina symptoms
