clinical skills questions

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: B

Rationale: Correct Answer: B Rationale: 1. Hemofilter clotting can affect CRRT efficiency. 2. Assessing every 6 hours allows early detection and intervention. 3. Clotting can lead to treatment interruptions or complications. 4. Regular assessment ensures optimal therapy delivery. Other Choices: A: Assessing tubing warmth is not a reliable indicator of CRRT function or complications. C: Covering dialysis lines to protect from light is not a standard practice in CRRT monitoring. D: Using clean technique is not sufficient for vascular access dressing changes; aseptic technique is required for infection prevention.

Correct Answer: D

Rationale: The correct answer is D: syndrome of inappropriate secretion of antidiuretic hormone (SIADH). In this scenario, the patient's symptoms of decreased urine output, shortness of breath, edema, and mental status changes are indicative of fluid overload due to SIADH. SIADH causes excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. This results in edema, decreased urine output, and neurological symptoms. A: Adrenal crisis presents with hypotension, shock, and electrolyte abnormalities, not consistent with the patient's symptoms. B: Diabetes insipidus would present with excessive urine output and thirst, opposite of the patient's symptoms. C: Myxedema coma results from severe hypothyroidism and presents with hypothermia, bradycardia, and altered mental status, not consistent with the patient's symptoms. In summary, the patient's clinical presentation aligns

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: 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.
