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: 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.

Correct Answer: C

Rationale: Step-by-step rationale for the correct answer (C: hyperkalemia): 1. Adrenal crisis leads to adrenal insufficiency, causing decreased cortisol levels. 2. Cortisol plays a crucial role in regulating potassium levels. 3. With decreased cortisol, potassium levels can rise, leading to hyperkalemia. 4. Hyperkalemia can result in life-threatening cardiac arrhythmias. Summary: A: Fluid volume excess is not typical in adrenal crisis. B: Hyperglycemia can be present but is not the most significant finding. D: Hypernatremia is not a typical feature of adrenal crisis.

Correct Answer: A

Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function as healthy kidneys should not allow large molecules like proteins to pass through the filtration barrier. This could be a sign of kidney damage or dysfunction. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not specific indicators of renal function issues. Sodium is actively reabsorbed in the renal tubules, creatinine is a waste product filtered by the kidneys, and a small number of red blood cells may pass through the filtration barrier under normal circumstances.

Correct Answer: B

Rationale: The elevated BUN and serum creatinine levels with a normal BUN/creatinine ratio suggest kidney dysfunction. This pattern is commonly seen in acute kidney injury, like acute tubular necrosis (ATN), where the kidneys are unable to properly filter waste products. Other choices (A) increased nitrogen intake and (C) hypovolemia would not cause the specific pattern of elevated BUN and creatinine levels with a normal ratio. (D) Fluid resuscitation would actually aim to correct hypovolemia and would not directly affect the BUN and creatinine levels.
