1. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

2. A nurse is caring for a client who is 12 hr postpartum and has a third-degree perineal laceration. The client reports not having a bowel movement for 4 days. Which of the following medications should the nurse administer?

Correct answer: A

Rationale: In this scenario, the nurse should administer Bisacodyl 10 mg rectal suppository. Bisacodyl is a stimulant laxative that promotes bowel movement, which is appropriate for a postpartum client experiencing constipation. Magnesium hydroxide (choice B) is an antacid and not indicated for constipation. Famotidine (choice C) is an H2 receptor antagonist used for reducing stomach acid production, not for constipation. Loperamide (choice D) is an antidiarrheal agent and would worsen constipation in this case.

3. A client who has a new prescription for prednisone is being taught by a nurse. Which of the following statements by the client indicates an understanding of the teaching?

Correct answer: B

Rationale: The correct answer is B because prednisone is usually prescribed for long-term use. Stopping it abruptly can lead to adrenal insufficiency. Choice A is incorrect because prednisone should be taken with food to prevent stomach upset. Choice C is incorrect as prednisone is typically tapered off gradually to avoid adverse effects. Choice D is incorrect as there is no specific requirement to take prednisone with a high-protein snack.

4. A nurse is caring for a client who has cirrhosis and a new prescription for lactulose. The nurse should monitor the client for which of the following therapeutic effects of this medication?

Correct answer: C

Rationale: The correct answer is C: Decreased serum ammonia. Lactulose is prescribed to decrease serum ammonia levels in clients with cirrhosis and hepatic encephalopathy. By reducing serum ammonia, lactulose helps improve the mental status of these clients. Therefore, monitoring for decreased serum ammonia is crucial to assess the effectiveness of lactulose therapy. Choice A (Improved mental status) is indirectly related as it is the desired outcome of decreasing ammonia levels. Choices B (Increased urine output) and D (Decreased bilirubin levels) are not directly associated with the therapeutic effects of lactulose in cirrhosis and hepatic encephalopathy.

5. A nurse is preparing to administer an intermittent enteral feeding to a client who has a nasogastric tube. Which of the following actions should the nurse take?

Correct answer: C

Rationale: The correct action for the nurse to take when preparing to administer an intermittent enteral feeding through a nasogastric tube is to flush the tube with 10 mL of water after feeding. This helps maintain tube patency and prevent clogging. Choice A, checking for residual feeding contents, is not the immediate action to take before administering the feeding. Choice B, administering the feeding through a large-bore syringe, is not the recommended method for administering enteral feedings. Choice D, administering the feeding at room temperature, is important but not the immediate action related to tube maintenance.
