Final answer:
The nurse would question options b and e.
Step-by-step explanation:
In this case, the nurse would question options b and e.
Option b involves administering 60 mEq of KCl to a patient with a serum potassium level of 3.2 mEq/L. This dosage would further increase the potassium level, potentially leading to hyperkalemia.
Option e, which is administering Potassium chloride, 10 mEq as a rapid IV push, poses a risk of causing cardiac arrest.
