Final answer:
The nurse should monitor for hypokalemia, hyperglycemia, and sulfa allergy as adverse reactions when administering hydrochlorothiazide to a client.
Step-by-step explanation:
The nurse should monitor for hypokalemia, hyperglycemia, and sulfa allergy as adverse reactions when administering hydrochlorothiazide to a client. Hydrochlorothiazide is a diuretic used to treat hypertension. It works by inhibiting the reabsorption of sodium (Na+) and chloride (Cl-) ions in the ascending limb of the loop of Henle in the kidney.
This increases the excretion of fluid and electrolytes, which can lead to the adverse reactions mentioned. Hypokalemia is a decrease in potassium levels, hyperglycemia is an increase in blood glucose levels, and sulfa allergy is an allergic reaction to sulfa-based medications.
