- C. Naproxen (Naprosyn)

A nurse would administer phentolamine to a client diagnosed with which condition?
- A. Pheochromocytoma-induced hypertension
- B. Benign hypertension
- C. Preoperative hypertension
- D. Increased intraocular pressure
- E. Treatment of dopamine extravasation tissue damage
Correct Answer: A,C,E
Rationale: Phentolamine is an a-adrenergic blocker used in the treatment of pheochromocytoma-induced hypertension and preoperative hypertension and in the prevention and treatment of tissue damage caused by extravasation of dopamine.
A client who is receiving a b blocker tells the nurse that he also takes ibuprofen for arthritis pain. The nurse would be alert for which of the following?
- A. Decreased effect of the b blocker
- B. Increased risk of bradycardia
- C. Increased risk of paradoxical hypertensive effect
- D. Increase risk of hypotension
Correct Answer: A
Rationale: The nurse should monitor for the decreased effect of the b blocker in the client who is receiving a b blocker along with NSAIDs. The nurse need not monitor for increased risk of bradycardia and paradoxical hypertensive effect or decreased risk of hypotension. There is an increase in the risk of paradoxical hypertensive effect when a b-adrenergic blocking drug is administered with clonidine. There is an increase in the risk of bradycardia when a b-adrenergic blocking drug is administered with antidepressants. There is an increased risk of hypotension when a b-adrenergic blocking drug is administered with loop diuretics.
A client with cardiac arrhythmia is treated with a centrally acting antiadrenergic drug. The nurse would assess the client for which of the following as a possible adverse reaction?
- A. Lightheadedness
- B. Malaise
- C. Bradycardia
- D. Weakness
Correct Answer: B
Rationale: The nurse should monitor the client for malaise as a generalized reaction with antiadrenergic drugs that are centrally acting when administered to clients with cardiac arrhythmias. Lightheadedness, bradycardia, and weakness are the adverse reactions associated with peripherally acting antiadrenergic drugs.
A nurse is caring for a client who has been prescribed propranolol for angina. After administering the drug, which of the following would the nurse do?
- A. Ask about relief of symptoms and record responses on the chart
- B. Determine signs of infection in the client
- C. Monitor for sudden decrease in urine output
- D. Monitor for sudden increase in intraocular pressure
Correct Answer: A
Rationale: The nurse should ask about the relief of symptoms and record the responses on the client's chart. Determining the signs of infection in the client is part of the nurse's preadministration assessment, not the ongoing assessment. The nurse need not monitor the client for a sudden decrease in urine output and a sudden increase in intraocular pressure for a client receiving propranolol therapy for angina.
A nurse is conducting discharge teaching with a client being discharged on clonidine (Catapres). The nurse would instruct the client about which of the following as a possible adverse reaction?
- A. Dry mouth
- B. Bradycardia
- C. Sedation
- D. Anorexia
- E. Tachypnea
Correct Answer: A,C,D
Rationale: Adverse reactions associated with the use of centrally acting antiadrenergic drugs like clonidine (Catapres) include dry mouth, drowsiness, sedation, anorexia, rash, malaise, and weakness.
