1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. A client is starting to take amitriptyline. The healthcare provider should instruct the client to monitor for which of the following adverse effects?

• A. Diarrhea
• B. Urinary retention
• C. Bradycardia
• D. Dry cough

Correct answer: B

Rationale: The correct answer is B: Urinary retention. Amitriptyline, a tricyclic antidepressant, can cause relaxation of the bladder sphincter muscles, leading to urinary retention. Monitoring for urinary retention is crucial as it is a common anticholinergic effect associated with this medication. Diarrhea (choice A) is not a common adverse effect of amitriptyline. Bradycardia (choice C) is more commonly associated with beta-blockers rather than tricyclic antidepressants like amitriptyline. Dry cough (choice D) is not a typical adverse effect of amitriptyline.

3. When teaching a client with a prescription for long-term use of oral prednisone for chronic asthma, the nurse should instruct the client to monitor for which of the following adverse effects of this medication?

• A. Weight gain
• B. Nervousness
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: The correct answer is weight gain. Weight gain and fluid retention are common adverse effects of oral prednisone due to sodium and water retention. Patients on long-term prednisone therapy should be advised to monitor their weight closely and report any significant changes to their healthcare provider. Choice B, 'Nervousness,' is not typically associated with oral prednisone use. Choice C, 'Bradycardia,' refers to a slow heart rate, which is not a common adverse effect of prednisone. Choice D, 'Constipation,' is not a typical adverse effect of oral prednisone; instead, gastrointestinal disturbances like increased appetite or even peptic ulcer disease may occur.

4. A client has a prescription for Erythromycin. Which of the following instructions should be included?

• A. Take the medication with food.
• B. Expect your urine to turn dark yellow.
• C. Take the medication with a full glass of milk.
• D. Report persistent diarrhea to your provider.

Correct answer: D

Rationale: The correct answer is D: 'Report persistent diarrhea to your provider.' Erythromycin is known to cause Clostridium difficile-associated diarrhea, which can be severe. Instructing the client to report any persistent diarrhea to their healthcare provider promptly is crucial to prevent complications. Choices A, B, and C are incorrect. Taking Erythromycin with food is generally recommended to reduce stomach upset, but it is not the most critical instruction. Expecting urine to turn dark yellow is not a common side effect of Erythromycin. Taking Erythromycin with a full glass of milk is not necessary and may not be appropriate for all clients, especially those with lactose intolerance or dairy allergies.

5. Which medication is contraindicated with Nitroglycerin?

• A. Hydrochloroquine
• B. Methylprednisolone
• C. Phenazopyridine
• D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.
