Correct Answer: B

Rationale: The correct answer is B: Bowel inflammation. Bowel inflammation can decrease the absorption of medications, reducing their effectiveness. Improved mobility (choice A) would generally not contribute to a decrease in medication effectiveness. Long-term use of the medication (choice C) may lead to tolerance but would not directly cause a decrease in effectiveness. Frequent dehydration (choice D) can affect overall health but is not a direct factor in the medication's effectiveness for arthritis.

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: 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: Frequent urge suppression can lead to constipation, especially postoperatively. Suppressing the urge to defecate can disrupt normal bowel movements and result in constipation. Increased physical activity, increased fiber intake, and adequate fluid intake are measures that typically help prevent constipation by promoting bowel regularity and preventing stool hardening. Therefore, choices A, C, and D are not behaviors that increase the client's risk for constipation.

Correct Answer: D

Rationale: The correct answer is D: Decreased abdominal distention. This finding indicates that the client is tolerating the feeding well without experiencing bloating or discomfort. Nausea and vomiting (choice A) are symptoms of intolerance to enteral feedings. Normal bowel sounds (choice B) are a good sign but do not directly indicate tolerance to the feeding. Weight gain (choice C) may occur due to factors other than enteral feedings.
