Correct Answer: D

Rationale: The correct action for the nurse to take when administering medications through a nasogastric (NG) tube is to dissolve medications separately and flush the tube with sterile water. This is important to prevent interactions between medications and ensure accurate administration. Option A is incorrect because tap water may not be sterile and could lead to contamination. Option B is incorrect as it increases the risk of drug interactions and may affect the effectiveness of each medication. Option C is incorrect as 60 mL of water before each medication may not be enough to ensure proper medication delivery and prevent interactions.

Correct Answer: B

Rationale: The correct intervention to reduce the risk of deep vein thrombosis (DVT) after surgery is to use compression stockings. Compression stockings help prevent DVT by promoting venous return, which reduces the likelihood of blood pooling in the legs and forming clots. Choices A, C, and D are incorrect because avoiding ambulation can actually increase the risk of DVT, using a heating pad does not directly address DVT prevention, and elevating the client's legs on a pillow alone may not provide sufficient compression to prevent DVT.

Correct Answer: A

Rationale: Using written communication is the most effective action for a nurse when assessing a client with hearing loss. This method helps overcome communication barriers by providing information visually, ensuring the client understands the assessment questions and instructions. Speaking louder (choice B) may distort the sound and not necessarily improve understanding. Facing the client (choice C) is important for lip reading but may not be sufficient for effective communication. Providing care in a quiet environment (choice D) is beneficial but might not fully address the need for clear communication in the assessment process for a client with hearing loss.

Correct Answer: C

Rationale: The correct answer is C: 'Use a special mattress to reduce pressure on the skin.' This intervention is crucial in preventing skin breakdown in clients with limited mobility as it helps to reduce pressure on bony prominences. Repositioning every 4 hours (Choice A) is important but may not be sufficient to prevent skin breakdown entirely. Applying lotion every 2 hours (Choice B) may not address the root cause of skin breakdown related to pressure. Increasing fluid intake (Choice D) is beneficial for overall skin health but may not directly prevent skin breakdown caused by pressure points.

Correct Answer: C

Rationale: The correct answer is C: Decrease in moisture levels. In older adults, there is a reduction in oil production, leading to decreased moisture levels in the skin. This change can result in dry skin and increased risk of skin issues. The other choices are incorrect because in older adults, skin turgor tends to decrease, subcutaneous fat may decrease, and oil production typically decreases rather than increases.
