Correct Answer: B

Rationale: The most appropriate nursing intervention when a client with a nasogastric tube experiences nausea and a decrease in gastric secretions is to aspirate the gastric contents with a syringe. This action helps relieve nausea by removing excess fluid and gas. Option A, irrigating the nasogastric tube with distilled water, is not indicated as it does not address the underlying issue of decreased gastric secretions. Option C, administering an antiemetic medication, may provide symptomatic relief but does not address the mechanical issue of decreased flow in the nasogastric tube. Option D, inserting a new nasogastric tube, is not necessary unless there are specific complications or obstructions in the current tube.

Correct Answer: A

Rationale: The correct answer is A: Perform Kegel exercises daily. After a radical prostatectomy, Kegel exercises are beneficial as they help strengthen the pelvic floor muscles, aiding in urinary control and recovery. Choice B is incorrect because recommending 3 hours of light exercise daily may not be suitable immediately postoperatively. Choice C is incorrect as personal hygiene, including bathing, is important for postoperative care. Choice D is incorrect because sitting for more than 2 hours does not specifically relate to the client's postoperative care needs.

Correct Answer: C

Rationale: Irritability in infants can indicate worsening dehydration, which needs to be reported. Weight gain (Choice A) would be a positive finding, indicating adequate fluid intake. Poor appetite (Choice B) is common with diarrhea but not as concerning as irritability. Decreased urination (Choice D) can also be a sign of dehydration, but irritability is more specific to worsening dehydration in this case.

Correct Answer: C

Rationale: An oxygen saturation of 90% is below the expected reference range and could indicate respiratory depression, a serious side effect of morphine. This finding requires immediate attention as it may lead to hypoxia. Nausea (choice A) is a common side effect of morphine but does not pose an immediate threat. A urinary output of 20 mL/hr (choice B) may indicate decreased renal perfusion but is not as critical as respiratory compromise. A respiratory rate of 14/min (choice D) is within the normal range and does not suggest immediate danger.

Correct Answer: B

Rationale: Restlessness and agitation in clients with dementia should be addressed immediately as they can indicate underlying causes such as pain, discomfort, or unmet needs. Addressing these symptoms promptly can help prevent the escalation of behavioral issues and improve the client's quality of life. While frequent episodes of wandering at night, mild confusion during the day, and incontinence are also important issues to address in clients with dementia, restlessness and agitation usually require immediate attention to ensure the safety and well-being of the client.
