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 client should be treated by giving potassium by IV bolus.
Another formulation of potassium should be given IV.
Potassium chloride should be diluted in dextrose 5% in water.
The potassium infusion rate is too rapid.
The Correct Answer is D
Choice A rationale:
IV bolus administration of potassium is not appropriate due to the risk of cardiac arrhythmias.
Choice B rationale:
The formulation of potassium (potassium chloride) is appropriate for IV administration.
Choice C rationale:
Potassium chloride is typically diluted in normal saline (0.9% sodium chloride) for IV administration, not dextrose.
Choice D rationale:
The prescribed infusion rate of 30 mEq of potassium chloride over 30 minutes is too rapid and could lead to adverse effects, such as cardiac arrhythmias. The nurse should clarify the prescription and discuss a slower infusion rate with the provider.

Correct Answer is B
Explanation
Choice A rationale:
While diphenhydramine is used to manage allergic reactions, epinephrine is the first-line treatment for severe anaphylactic reactions.
Choice B rationale:
In cases of anaphylactic reactions, epinephrine is the first-line treatment to reverse the severe allergic response. It helps to relieve bronchoconstriction, improve blood pressure, and counteract the symptoms of anaphylaxis.
Choice C rationale:
Elevating the client's legs and feet is not the appropriate intervention for anaphylactic reactions.
Choice D rationale:
Replacing the infusion with 0.9% sodium chloride is not the priority action in managing anaphylactic reactions. Administering epinephrine and managing the client's airway and circulation are more important.
Correct Answer is C
Explanation
Choice A rationale:
Bradycardia (slow heart rate) is not a primary concern when administering lisinopril.
Choice B rationale:
Hypokalemia (low potassium levels) can be a concern with certain medications, but it is not directly related to lisinopril administration.
Choice C rationale:
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor commonly used to treat heart failure. One of the potential side effects of ACE inhibitors is hypotension (low blood pressure), so the nurse should monitor the client's blood pressure closely during and after administration.
Choice D rationale:
Tinnitus (ringing in the ears) is not a common side effect of lisinopril.
