Which of the following patients is at the highest risk for hyperosmolar hyperglycemic syndrome?
- A. An 18-year-old college student with type 1 diabetes who exercises excessively
- B. A 45-year-old woman with type 1 diabetes who forgets to take her insulin in the morning
- C. A 75-year-old man with type 2 diabetes and coronary artery disease who has recently started on insulin injections
- D. An 83-year-old, long-term care resident with type 2 diabetes and advanced Alzheimer’s disease who recently developed influenza
Correct Answer: D
Rationale: The correct answer is D because the 83-year-old long-term care resident with type 2 diabetes and advanced Alzheimer's disease who recently developed influenza is at the highest risk for hyperosmolar hyperglycemic syndrome (HHS). This patient has multiple risk factors for HHS, including age, type 2 diabetes, advanced Alzheimer's disease, and the added stress of influenza, which can exacerbate hyperglycemia. The combination of these factors can lead to severe hyperglycemia, dehydration, and electrolyte imbalances characteristic of HHS.
Choice A is incorrect because although excessive exercise can lead to hypoglycemia in individuals with type 1 diabetes, it is not a risk factor for HHS. Choice B is incorrect as forgetting to take insulin can lead to diabetic ketoacidosis in type 1 diabetes, not HHS. Choice C is incorrect as starting insulin injections in a patient with type 2 diabetes and coronary artery disease does not automatically increase the risk

Slow continuous ultrafiltration is also known as isolated ultrafiltration and is used to
- A. remove plasma water in cases of volume overload.
- B. remove fluids and solutes through the process of convection.
- C. remove plasma water and solutes by adding dialysate.
- D. combine ultrafiltration, convection, and dialysis.
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).
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 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.
What is a minimally acceptable urine output for a patient weighing 75 kg?
- A. Less than 30 mL/hour
- B. 37 mL/hour
- C. 80 mL/hour
- D. 150 mL/hour
Correct Answer: C
Rationale: The correct answer is C (80 mL/hour) as it is considered a minimally acceptable urine output for a patient weighing 75 kg. Adequate urine output is crucial for kidney function and fluid balance. The general rule is to maintain a urine output of at least 0.5 mL/kg/hour, which in this case would be 37.5 mL/hour for a 75 kg patient. Option C (80 mL/hour) exceeds this minimum requirement, ensuring proper kidney perfusion and waste elimination. Options A (Less than 30 mL/hour) and D (150 mL/hour) are incorrect as they fall below or exceed the recommended urine output range, potentially indicating renal impairment or fluid overload, respectively. Option B (37 mL/hour) is close to the minimum requirement but does not provide a sufficient margin for variations in fluid status or kidney function.
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.
