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: 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: 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.

Correct Answer: B

Rationale: The correct answer is B: Administer 15 grams of carbohydrate orally for severe episodes of hypoglycemia. In this scenario, the patient is experiencing severe hypoglycemia (blood glucose of 32 mg/dL) leading to loss of consciousness and seizure activity. Administering 15 grams of carbohydrate orally is crucial to rapidly raise the blood glucose levels and address the hypoglycemia. This immediate intervention can help reverse the symptoms and prevent further complications. The incorrect choices: A: Administering glucagon intramuscularly is typically reserved for severe hypoglycemia when the patient cannot take anything by mouth. In this case, oral intake is preferred for faster absorption. C: Discontinuing the insulin pump is not necessary in this situation since the primary concern is treating the acute hypoglycemia. Removing the infusion set can lead to hyperglycemia if not managed properly. D: Increasing home blood glucose monitoring and reporting patterns of hyp

Correct Answer: D

Rationale: The correct answer is D: Urine osmolality. In head trauma patients, the risk of developing diabetes insipidus (DI) is high due to damage to the posterior pituitary. Monitoring urine osmolality helps identify DI early, as low urine osmolality indicates impaired concentration ability. This is crucial for prompt treatment to prevent dehydration. Choices A and B are important but not specific to endocrine disorders. Choice C is relevant for respiratory assessment, not endocrine disorders.
