A nurse is providing discharge teaching to a client who has a new prescription for metformin. Which of the following instructions should the nurse include?

Correct Answer: D

Rationale: The correct answer is D because taking metformin with food helps reduce gastrointestinal discomfort, a common side effect of the medication. Choice A is incorrect as metformin is usually taken with meals to minimize side effects. Choice B is incorrect because metformin does not typically cause urine discoloration. Choice C is incorrect as metformin is associated with weight loss or weight neutrality rather than weight gain.

Correct Answer: D

Rationale: The correct answer is D. Absent deep-tendon reflexes indicate magnesium toxicity and should be reported immediately. Magnesium sulfate is used to prevent seizures in clients with preeclampsia, but toxicity can lead to serious complications, including respiratory depression and loss of deep-tendon reflexes. Choices A, B, and C are within normal limits and expected findings in a client receiving magnesium sulfate for preeclampsia, so they do not require immediate reporting.

Correct Answer: D

Rationale: The correct answer is D because clients taking warfarin should avoid aspirin to reduce the risk of bleeding, as both medications can thin the blood. Choice A is incorrect because it is essential to eat a consistent amount of leafy green vegetables to maintain a steady intake of Vitamin K, which can impact warfarin's effectiveness. Choice B is incorrect although important because INR checks are necessary but do not specifically show an understanding of the teaching. Choice C is incorrect because while taking warfarin at the same time each day is beneficial for consistency, it does not directly address the interaction with aspirin.

Correct Answer: B

Rationale: During an acute exacerbation of Crohn's disease, the nurse should maintain the client on a low-residue diet. This diet helps to minimize bowel irritation by reducing the volume and frequency of stools. Choices A, C, and D are incorrect. Encouraging the client to increase dietary fiber (Choice A) and eat a high-fiber diet (Choice D) can worsen symptoms and aggravate bowel inflammation in Crohn's disease. Providing the client with frequent high-calorie snacks (Choice C) may not be appropriate during an exacerbation since high-fat foods can be harder to digest and may exacerbate symptoms.

Correct Answer: A

Rationale: The correct answer is A: Constant bubbling in the water seal chamber. Constant bubbling in the water seal chamber can indicate an air leak, which compromises the integrity of the chest tube system and should be reported to the provider for immediate intervention. Choices B, C, and D are incorrect. Intermittent bubbling in the suction control chamber is an expected finding indicating that the system is working appropriately. Tidaling in the water seal chamber is a normal fluctuation of fluid level with inspiration and expiration, indicating that the system is functioning correctly. Drainage of 75 mL in the first 24 hours is within the expected range for chest tube drainage and does not require immediate reporting unless accompanied by other concerning symptoms.
