clinical skills questions

Correct Answer: C

Rationale: The correct answer is C (80 mL/hour) as it is considered a minimally acceptable urine output for a patient weighing 75 kg. Adequate urine output is crucial for kidney function and fluid balance. The general rule is to maintain a urine output of at least 0.5 mL/kg/hour, which in this case would be 37.5 mL/hour for a 75 kg patient. Option C (80 mL/hour) exceeds this minimum requirement, ensuring proper kidney perfusion and waste elimination. Options A (Less than 30 mL/hour) and D (150 mL/hour) are incorrect as they fall below or exceed the recommended urine output range, potentially indicating renal impairment or fluid overload, respectively. Option B (37 mL/hour) is close to the minimum requirement but does not provide a sufficient margin for variations in fluid status or kidney function.

Correct Answer: A

Rationale: The correct answer is A: a diet of 2500 to 3500 kcal per day. During hemodialysis, patients often experience increased energy expenditure due to the treatment process. Therefore, maintaining a higher caloric intake is crucial to prevent malnutrition and support the body's needs. Options B, C, and D are incorrect as limiting protein intake to less than 50 grams per day may lead to malnutrition in a patient undergoing hemodialysis, restricting potassium intake to 10 mEq per day may not be appropriate as individual needs vary, and restricting fluid intake to less than 500 mL per day can lead to dehydration and electrolyte imbalances in a patient undergoing hemodialysis.

Correct Answer: A

Rationale: Rationale: Slow continuous ultrafiltration is a method used to remove excess plasma water in cases of volume overload, making choice A the correct answer. This process does not involve adding dialysate (choice C) or combining ultrafiltration, convection, and dialysis (choice D). While ultrafiltration does involve the removal of fluids and solutes, it is primarily achieved through ultrafiltration rather than convection (choice B).

Correct Answer: C

Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is essential in monitoring for signs of infection or complications. Redness and swelling can indicate infection, which requires prompt intervention. A: Applying a sterile gauze dressing is not necessary for a temporary percutaneous dialysis catheter unless specified by the healthcare provider. B: Transparent dressings are typically left in place for several days unless there is a specific reason to change them more frequently. D: Using the catheter for drawing blood samples is not recommended as it can increase the risk of infection and may interfere with the dialysis process.
