clinical skills questions

Correct Answer: D

Rationale: The correct answer is D: inform the provider of probable visceral perforation. This is the most urgent action as sudden abdominal pain, chills, and elevated temperature in a patient receiving peritoneal dialysis could indicate a serious complication like visceral perforation, which requires immediate medical attention to prevent further complications. Assessing peritoneal dialysate return (A) may provide some information but does not address the urgent need to address a potential visceral perforation. Checking the patient's blood sugar (B) and evaluating the patient's neurological status (C) are not priorities in this situation and do not address the potential life-threatening complication of visceral perforation.

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: �The fistula will be usable in about 4 to 6 weeks.� This is because arteriovenous fistulas typically require a maturation period of 4 to 6 weeks before they can be used for dialysis. During this time, the fistula will develop into a strong, durable access point for hemodialysis. Choice A is incorrect because the fistula needs time to mature before it can be used, and immediate use may damage it. Choice B is incorrect as it underestimates the maturation period required. Choice D is incorrect as the maturation time does not depend on the manufacturer but on the patient's physiology and healing process.

Correct Answer: C

Rationale: Correct Answer: C - Increased ability to excrete drugs. Rationale: 1. Renal insufficiency impairs kidney function, leading to decreased excretion of drugs. 2. In elderly patients with renal insufficiency, there may be compensatory mechanisms to enhance drug excretion. 3. This increased ability to excrete drugs helps prevent drug accumulation and potential toxicity. Summary: A: Increased GFR is not expected in renal insufficiency; it typically decreases. B: Serum creatinine level would likely be elevated in renal insufficiency, not normal. D: Hypokalemia is not a typical lab finding in renal insufficiency; hyperkalemia is more common.

Correct Answer: D

Rationale: The correct answer is D: ultrafiltration. Ultrafiltration involves the removal of plasma water and low-molecular weight particles using a pressure or osmotic gradient. This process allows small molecules to pass through a semipermeable membrane while retaining larger molecules. Dialysis (A) involves the removal of waste products and excess fluids from the blood, while diffusion (B) is the movement of molecules from an area of high concentration to low concentration. Clearance (C) refers to the rate at which a substance is removed from the blood by a specific organ or process. Ultrafiltration specifically targets the removal of plasma water and low-molecular weight particles through a pressure or osmotic gradient, making it the correct choice in this context.
