An individual with type 2 diabetes who takes glipizide has begun a formal exercise program at a local gym. While exercising on the treadmill, the individual becomes pale, diaphoretic, shaky, and has a headache. The individual feels as though she is going to pass out. What is the individual’s priority action?
- A. Drink additional water to prevent dehydration.
- B. Eat something with 15 g of simple carbohydrates.
- C. Go to the first-aid station to have glucose checked.
- D. Take another dose of the oral agent.
Correct Answer: B
Rationale: The correct answer is B: Eat something with 15 g of simple carbohydrates. In this scenario, the individual is exhibiting signs of hypoglycemia due to the combination of glipizide (which can lower blood sugar) and exercise. The priority action is to raise blood sugar levels quickly to prevent further complications. Consuming simple carbohydrates, like glucose tablets or juice, will rapidly increase blood sugar levels. This is crucial to prevent the individual from passing out or experiencing more serious consequences.
Choice A is incorrect because while hydration is important, it is not the immediate priority in this situation. Choice C is incorrect as going to the first-aid station may waste valuable time when immediate action is needed. Choice D is incorrect as taking another dose of the oral agent can further lower blood sugar levels and worsen the hypoglycemia.

A patient with long-standing type 1 diabetes presents to the emergency department with a loss of consciousness and seizure activity. The patient has a history of renal insufficiency, gastroparesis, and peripheral diabetic neuropathy. Emergency personnel reported a blood glucose of 32 mg/dL on scene. When providing discharge teaching for this patient and family, the nurse instructs on the need to do which of the following? (Select all that apply.)
- A. Administer glucagon 1 mg intramuscularly any time the blood glucose is less than 70 mg/dL.
- B. Administer 15 grams of carbohydrate orally for severe episodes of hypoglycemia.
- C. Discontinue the insulin pump by removing the infusion set catheter.
- D. Increase home blood glucose monitoring and report patterns of hypoglycemia to the provider.
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
The patient undergoes a cardiac catheterization that requires the use of contrast dyes during the procedure. To detect signs of contrast-induced kidney injury, the nurse should
- A. not be concerned unless urine output decreases.
- B. evaluate the patient’s serum creatinine for up to 72 hours after the procedure.
- C. obtain an order for a renal ultrasound.
- D. evaluate the patient’s postvoid residual volume to detect intrarenal injury.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. Contrast dyes can cause kidney injury due to their nephrotoxic effects.
2. Serum creatinine levels are a reliable indicator of kidney function.
3. Evaluating serum creatinine for up to 72 hours after the procedure allows detection of any contrast-induced kidney injury.
4. Monitoring serum creatinine helps in early identification and intervention for renal complications.
Summary:
A: Incorrect. Urine output alone is not a definitive indicator of kidney injury.
C: Incorrect. Renal ultrasound is not typically used for detecting contrast-induced kidney injury.
D: Incorrect. Postvoid residual volume is not specific for contrast-induced kidney injury.
The nurse is caring for a patient who has undergone major abdominal surgery. The nurse notices that the patient’s urine output has been less than 20 mL/hour for the past 2 hours. The patient’s blood pressure is 100/60 mm Hg, and the pulse is 110 beats/min. Previously, the pulse was 90 beats/min with a blood pressure of 120/80 mm Hg. The nurse should
- A. contact the provider and expect a prescription for a normal saline bolus.
- B. wait until the provider makes rounds to report the assessment findings.
- C. continue to evaluate urine output for 2 more hours.
- D. ignore the urine output, as this is most likely postrenal in origin.
Correct Answer: A
Rationale: Rationale:
1. Urine output < 20 mL/hour indicates potential hypoperfusion.
2. Decreased urine output with hypotension and tachycardia suggests inadequate fluid resuscitation.
3. Administering a normal saline bolus can help improve perfusion and stabilize blood pressure.
4. Contacting the provider promptly for orders is crucial in managing this acute situation.
Summary of Incorrect Choices:
B. Delaying reporting to the provider risks worsening the patient's condition.
C. Continuing to evaluate urine output without intervention can lead to further deterioration.
D. Ignoring the urine output due to potential postrenal causes overlooks the urgent need for fluid resuscitation.
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 patient has elevated blood urea nitrogen (BUN) and serum creatinine levels with a normal BUN/creatinine ratio. These levels most likely indicate
- A. increased nitrogen intake.
- B. acute kidney injury, such as acute tubular necrosis (ATN).
- C. hypovolemia.
- D. fluid resuscitation.
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.
