A nurse would closely monitor which client for an increase in possible adverse reactions after administering propranolol?
- A. Clients with asthma
- B. Clients with hyperlipidemia
- C. Clients with diabetes
- D. Clients with peptic ulcer disease
- E. Clients with migraine headaches
Correct Answer: A,C,D
Rationale: A nurse should carefully observe clients with asthma (bronchospasm can result with the use of nonselective b blockers) and diabetes (b blockers can mask the symptoms of hypoglycemia) during the use of propranolol (Inderal), a nonselective b blocker. The drug also should be used cautiously in clients with peptic ulcer disease.
