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.
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 B
Explanation
According to the CDC, people with severe, life-threatening allergies to any ingredient in a flu vaccine (other than egg proteins) should not get that vaccine. However, people with egg allergy can get a flu vaccine. The CDC also states that people who have had a severe allergic reaction to a dose of influenza vaccine should not get that flu vaccine again and might not be able to receive other influenza vaccines. Therefore, a nurse should report an egg allergy to the provider as a possible contraindication to receiving the vaccine.
Choice A is wrong because shellfish is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice C is wrong because milk is not an ingredient in a flu vaccine and is not a contraindication to receiving the vaccine.
Choice D is wrong because peanuts are not an ingredient in a flu vaccine and are not a contraindication to receiving the vaccine.
Correct Answer is D
Explanation
This is because a weight gain of 2.5 kg (5 Ib) in 2 days indicates a worsening of heart failure and fluid retention, which may require an adjustment of the diuretic dose or other medications.
The provider should be informed of this change as soon as possible to prevent further complications.
Choice A is wrong because teaching the client about foods low in sodium is not the first action the nurse should take.
While a low-sodium diet is important for heart failure patients, it is not an urgent intervention and it does not address the immediate problem of fluid overload.
Choice B is wrong because determining medication adherence by the client is not the first action the nurse should take.
While it is important to assess if the client is taking furosemide as prescribed, it is not an urgent intervention and it does not rule out other causes of fluid retention, such as renal impairment or disease progression.
Choice C is wrong because encouraging the client to dangle the legs while sitting in a chair is not the first action the nurse should take.
While this may help reduce edema in the lower extremities, it does not address the underlying cause of fluid overload and it may worsen pulmonary congestion by increasing venous return to the heart.
