The critical care nurse is responsible for monitoring the patient receiving continuous renal replacement therapy (CRRT). In doing so, the nurse should
- A. assess that the blood tubing is warm to the touch.
- B. assess the hemofilter every 6 hours for clotting.
- C. cover the dialysis lines to protect them from light.
- D. use clean technique during vascular access dressing changes.
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.

The nurse is assigned to care for a patient who presented to the emergency department with diabetic ketoacidosis. A continuous insulin intravenous infusion is started, and hourly bedside glucose monitoring is ordered. The targeted blood glucose value after the first hour of therapy is
- A. 70 to 120 mg/dL.
- B. a decrease of 25 to 50 mg/dL compared with admitting values.
- C. a decrease of 35 to 90 mg/dL compared with admitting values.
- D. less than 200 mg/dL.
Correct Answer: C
Rationale: The correct answer is C: a decrease of 35 to 90 mg/dL compared with admitting values. In diabetic ketoacidosis, there is severe hyperglycemia which needs to be corrected gradually to prevent complications like cerebral edema. A rapid decrease in glucose levels can lead to osmotic shifts and neurological issues. The targeted decrease of 35 to 90 mg/dL is considered safe and effective in managing hyperglycemia in these patients. This range ensures a controlled reduction in blood glucose levels without causing harm.
Choice A (70 to 120 mg/dL) is too broad and may lead to overly aggressive treatment. Choice B (a decrease of 25 to 50 mg/dL) is too conservative and may not adequately address the high glucose levels seen in diabetic ketoacidosis. Choice D (less than 200 mg/dL) does not provide a specific target range for glucose reduction, which is essential in managing diabetic ketoacidosis effectively.
The nurse is providing insulin education for an elderly patient with long-standing
diabetes. A prescription has been written for the patient to take 20 units of insulin glargine at 10
PM nightly. The nurse should instruct the patient that the peak of the insulin action for this agent
is
- A. 200
- B. 400
- C. 800
- D. peakless
Correct Answer: D
Rationale: The correct answer is D: peakless. Insulin glargine is a long-acting insulin with a smooth, consistent release of insulin over 24 hours, providing a steady level of insulin without a pronounced peak. This characteristic helps in maintaining stable blood glucose levels. Options A, B, and C are incorrect as they refer to peak values that do not apply to insulin glargine.
The nurse is caring for a patient receiving peritoneal dialysis. The patient suddenly complains of abdominal pain and chills. The patient’s temperature is elevated. The nurse should
- A. assess peritoneal dialysate return.
- B. check the patient’s blood sugar.
- C. evaluate the patient’s neurological status.
- D. inform the provider of probable visceral perforation.
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.
The nurse is caring for a patient with head trauma who was admitted to the surgical intensive care unit following a motorcycle crash. What is an important assessment that will assist the nurse in early identification of an endocrine disorder commonly associated with this condition?
- A. Daily weight
- B. Fingerstick glucose
- C. Lung sound auscultation
- D. Urine osmolality
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.
The most common reasons for initiating dialysis in acute kidney injury include which of the following? (Select all that apply.)
- A. Acidosis
- B. Hypokalemia
- C. Volume overload
- D. Hyperkalemia
Correct Answer: A
Rationale: Explanation:
A: Acidosis is a common reason to initiate dialysis in acute kidney injury due to impaired acid-base balance.
B: Hypokalemia is not a common reason for initiating dialysis in acute kidney injury.
C: Volume overload may require dialysis but is not as common as acidosis.
D: Hyperkalemia is a valid reason for dialysis but not as common as acidosis in acute kidney injury.
