Correct Answer: C

Rationale: The correct answer is C: Promote positive nitrogen balance. In a postsurgical patient, promoting positive nitrogen balance is crucial for wound healing and tissue repair. This goal helps prevent muscle wasting and promotes overall recovery. A: Reduce dependent nitrogen balance is incorrect as it does not address the need for positive nitrogen balance in wound healing. B: Maintain negative nitrogen balance is incorrect because negative nitrogen balance indicates a loss of protein stores, which is detrimental for healing. D: Facilitate neutral nitrogen balance is incorrect as it does not actively support the increased protein needs for wound repair.

Correct Answer: C

Rationale: The correct answer is C because encouraging the patient to verbalize concerns can help alleviate anxiety by allowing the patient to express emotions and fears. This intervention promotes emotional expression and provides an outlet for the patient to discuss their worries. This can lead to increased understanding and support. Incorrect answers: A: Administering antianxiety medications does not address the underlying cause of anxiety and may lead to dependency. B: Instructing the family on planning care does not directly address the patient's anxiety. D: Distracting the patient may provide temporary relief but does not address the root cause of anxiety related to lack of control over health circumstances.

Correct Answer: B

Rationale: The correct answer is B: Mitral valve prolapse. This condition is usually benign during pregnancy because the heart's workload increases, and the mitral valve is a one-way valve that prevents blood from flowing back into the left atrium. Mitral valve prolapse typically does not significantly affect the heart's ability to pump blood efficiently during pregnancy. Rationale: 1. Cardiomyopathy (A) can worsen during pregnancy, leading to complications for both the mother and the fetus. 2. Rheumatic heart disease (C) can cause valve damage, increasing the risk of complications during pregnancy. 3. Congenital heart disease (D) varies in severity and can pose risks during pregnancy, depending on the specific condition. Summary: Mitral valve prolapse is the correct answer as it is less likely to cause significant issues during pregnancy compared to the other options provided.

Correct Answer: D

Rationale: Rationale for Correct Answer (D): Checking with the pharmacy for availability of liquid forms of medications is the best action because it reduces the risk of clogging the nasogastric tube. Liquid medications are less likely to cause blockages compared to nonliquid medications. Additionally, liquid forms are easier to administer through the tube. By using liquid medications, the nurse can ensure that the medications flow smoothly through the tube without causing any obstructions. Summary of Incorrect Choices: A: Instilling nonliquid medications without diluting can increase the risk of tube clogging. B: Irrigating the tube with water after all medications are given may not prevent clogging effectively and could introduce unnecessary moisture into the tube. C: Mixing all medications together can lead to potential drug interactions and may not address the issue of tube clogging effectively.

Correct Answer: B

Rationale: The correct answer is B (2, 4, 1, 3, 5) because it follows the correct sequential order for initiating feeding. First, you need to prepare the food (2), then set up the feeding area (4), followed by inviting the person to eat (1), serving the food (3), and finally allowing them to eat (5). The other choices do not adhere to the logical sequence required for initiating feeding. Choice A and D have incorrect sequences of steps, while Choice C has steps 1 and 4 switched, which disrupts the proper order of initiating feeding.
