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 uses levodopa for treatment of Parkinson's disease. The client is now prescribed an adrenergic blocking agent. The nurse would assess the client for which of the following?
- A. Decreased effect of levodopa
- B. Increased effect of adrenergic blocker
- C. Increased risk of levodopa toxicity
- D. Decreased risk of psychotic behavior
Correct Answer: A
Rationale: When levodopa and adrenergic blockers are administered together, the effect of the levodopa is decreased. Therefore, the client's Parkinson's disease may not be controlled as effectively as before. The effect of the adrenergic blocker is not increased, nor is the risk for levodopa toxicity. The client is not experiencing psychotic behavior.
A client with a cardiac problem is treated with b-adrenergic blocking drugs. Which of the following should the nurse identify as a cardiac reaction that impacts the body when a b-adrenergic blocking drug is given to the client?
- A. Vomiting
- B. Hyperglycemia
- C. Nausea
- D. Vertigo
Correct Answer: D
Rationale: The nurse should identify vertigo as the cardiac reaction that impacts the body when a b-adrenergic blocking drug is given to the client. Vomiting, nausea, and hyperglycemia are not cardiac reactions; they are gastrointestinal reactions that are observed when the client is administered b-adrenergic blocking drugs.
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.
A nurse is preparing to administer propranolol to a client for the treatment of cardiac arrhythmias. The nurse checks the client's apical pulse rate and blood pressure before administration and notes that the pulse rate is below 60 bpm. Which of the following would the nurse do next?
- A. Provide proper ventilation to the client
- B. Delay drug administration for some time
- C. Withhold the drug and contact the primary health care provider
- D. Immediately give oxygen via face mask
Correct Answer: C
Rationale: The nurse should withhold the drug and contact the primary health care provider if the pulse rate of the client is below 60 bpm. Providing proper ventilation to the client, delaying drug administration for some time, or providing oxygen support to the client would be inappropriate for this client.
