Correct Answer: A

Rationale: Encouraging oral fluid intake is a crucial nursing intervention in managing a patient with fluid volume deficit. By encouraging oral fluid intake, the patient can increase hydration levels, helping to correct the deficit. Administering IV fluids may be necessary in severe cases or when the patient is unable to tolerate oral intake. Monitoring urine output and checking electrolyte levels are essential aspects of assessing fluid volume status, but they are not direct interventions for correcting fluid volume deficit. Monitoring skin turgor and capillary refill are important assessments for fluid volume status but are not direct management strategies.

Correct Answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

Correct Answer: C

Rationale: Increasing fiber intake is the most appropriate nursing intervention for a client experiencing constipation. Fiber helps add bulk to the stool, making it easier to pass and promoting regular bowel movements. Encouraging the client to remain in bed may exacerbate constipation by reducing movement and promoting inactivity. While stool softeners can be beneficial, they are typically used as a short-term solution and may not address the underlying issue of low fiber intake. Regular exercise is important for overall bowel health; however, in the immediate management of constipation, increasing fiber intake is the most effective intervention.

Correct Answer: A

Rationale: In acute renal failure, it is crucial to monitor urine output to assess kidney function and fluid balance. Administering diuretics helps manage fluid levels by promoting urine production. Choice B is incorrect because administering IV fluids can worsen fluid overload in renal failure patients, and restricting potassium intake is not typically the initial approach. Choice C is not the primary intervention but is important for long-term management. Choice D is incorrect as administering potassium can be dangerous in renal failure, and restricting fluids can lead to dehydration.

Correct Answer: B

Rationale: The correct answer is to check the client's capillary blood glucose level every 4 hours. Clients receiving TPN are at risk for hyperglycemia, so regular monitoring of blood glucose levels is essential to detect and manage hyperglycemia promptly. Administering TPN through a peripheral IV catheter (Choice A) is incorrect as TPN should be given through a central venous catheter to prevent complications. Heating the TPN solution to room temperature (Choice C) is unnecessary and not a standard practice. Weighing the client every 3 days (Choice D) is important for monitoring fluid status but is not the priority action when caring for a client receiving TPN.
