Correct Answer: A

Rationale: The correct answer is A: Increased thirst and frequent urination. These are classic signs of hyperglycemia, indicating elevated blood sugar levels. Choice B is incorrect as hyperglycemia usually presents with increased appetite rather than decreased appetite and low blood pressure. Choice C is incorrect as weight loss is more commonly associated with uncontrolled diabetes rather than hyperglycemia. Choice D is incorrect as increased sweating and confusion are not typical signs of hyperglycemia.

Correct Answer: B

Rationale: The correct first action for a client with an NG tube experiencing nausea and decreased gastric secretions is to irrigate the NG tube with sterile water. This helps alleviate blockages and can improve the client's symptoms. Increasing the suction pressure (Choice A) may exacerbate the issue and cause further discomfort. Turning the client onto their left side (Choice C) is not directly related to addressing the reported symptoms. Replacing the NG tube with a new one (Choice D) should be considered only after attempting initial interventions like irrigation.

Correct Answer: D

Rationale: When a client refuses medication, the nurse should inform the client of the possible consequences of refusal. This action helps the client understand the risks associated with not taking the medication. Asking the client to discuss their feelings (choice A) is important but should follow after informing them of the consequences. Explaining the importance of the medications (choice B) might not address the immediate concern of the client. Documenting the refusal and withholding the medication (choice C) should be done after informing the client of the consequences and attempting to address their concerns.

Correct Answer: A

Rationale: Corrected Question: When managing a patient with fluid overload, the appropriate approach involves restricting fluids and administering diuretics. This strategy helps remove excess fluid from the body and prevent complications associated with fluid overload. Choice B suggesting increasing fluid intake is incorrect as it would worsen the condition. Choice C, administering antibiotics, is unrelated to managing fluid overload. Choice D, monitoring weight and providing a low-sodium diet, is helpful but not as effective as fluid restriction and diuretics in managing fluid overload.

Correct Answer: A

Rationale: In clients with oliguria, hypertension, and peripheral edema, protein should be restricted in the diet to reduce the workload on the kidneys. Excessive protein intake can lead to increased BUN levels, which can further stress the kidneys. Restricting protein can help prevent further kidney damage. Fats, carbohydrates, and magnesium do not directly impact kidney function in the same way as protein does, making them incorrect choices in this scenario.
