Question 1 of 5
The nurse is administering the first dose of hydralazine to an older adult. The nurse should place the client on which of the following precautions?
Correct Answer: B
Rationale: Hydralazine can cause orthostatic hypotension, increasing fall risk in older adults. Other precautions are unrelated.
Question 2 of 5
The nurse is teaching the client prescribed verapamil to avoid which of the following foods?
Correct Answer: A
Rationale: Grapefruit increases verapamil levels by inhibiting metabolism, risking toxicity. Apples, bananas, and oranges have no significant interaction.
Question 3 of 5
A client who wants to quit smoking has a new prescription for varenicline [Chantix]. The nurse will instruct the client to notify the provider immediately with which of the following?
Correct Answer: D
Rationale: Varenicline can cause serious mood changes or suicidal thoughts, requiring immediate reporting. Cravings, nausea, and dry mouth are less urgent.
Question 4 of 5
A client with type 1 diabetes is taking propranolol [Inderal], acting confused, and reports weakness and feeling shaky. What must the nurse check first?
Correct Answer: B
Rationale: Propranolol masks hypoglycemia symptoms in type 1 diabetes; confusion and shakiness suggest low glucose, requiring immediate check over renal, BP, or electrolytes.
Question 5 of 5
A nurse is assessing a client who complains of a persistent, nonproductive dry cough after starting a new prescription for hypertension. Which of the following medications does the nurse suspect?
Correct Answer: A
Rationale: Captopril, an ACE inhibitor, commonly causes a dry cough due to bradykinin buildup. Nifedipine, verapamil, and propranolol do not typically cause this.
