Answer to Question 1

Correct Answer: 1
Rationale 1: The most common side effects of doxazosin (Cardura) include dizziness, drowsiness, fatigue, and weakness. Also, first-dose syncope can occur 30 to 90 minutes following the initial dose, so the nurse should teach the client to be cautious.
Rationale 2: Doxazosin (Cardura) has no effect on the bronchi or the bronchioles, since the receptors in the bronchus are beta2 receptors.
Rationale 3: Doxazosin (Cardura) causes relaxation of smooth muscle of the bladder and prostate, causing increased urinary frequency, not decreased urinary frequency.
Rationale 4: Doxazosin (Cardura) is a selective alpha1-adrenergic antagonist that causes a rapid decrease in peripheral resistance that reduces blood pressure. It does not have any effect on the smooth muscle of the GI tract.

Answer to Question 2

Correct Answer: 2,3,5
Rationale 1: Prazosin (Cardura) is a selective alpha1-antagonist drug and is not used to treat overdose of propranolol (Inderal).
Rationale 2: Isoproterenol is an adrenergic agonist that is used to treat overdose of propranolol to reverse the bronchoconstriction .
Rationale 3: Atropine is an anticholinergic drug that is used to treat overdose of propranolol to reverse the severe bradycardia.
Rationale 4: Metoprolol is a selective beta1-adrenergic antagonist and has actions similar to propranolol, so it cannot be used for treating overdose of this drug.
Rationale 5: Cardiac failure caused by beta antagonist overdose can be treated by administering digoxin (Lanoxin) or diuretics.
