Nursing Elites

1. A client with type 1 DM calls the nurse to report recurrent episodes of hypoglycemia with exercise. Which statement by the client indicates an inadequate understanding of the peak action of NPH insulin and exercise?

• A. The best time for me to exercise is every afternoon.
• B. The best time for me to exercise is right after I eat.
• C. The best time for me to exercise is after breakfast.
• D. The best time for me to exercise is after my morning snack.

Correct answer: A

Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.

2. A healthcare professional caring for a client who has been receiving intravenous diuretics suspects that the client is experiencing a deficient fluid volume. Which assessment finding would the healthcare professional note in a client with this condition?

• A. Lung congestion
• B. Decreased hematocrit
• C. Increased blood pressure
• D. Decreased central venous pressure (CVP)

Correct answer: D

Rationale: Decreased central venous pressure (CVP) is the correct assessment finding in a client with deficient fluid volume. This is because a decrease in CVP indicates reduced blood volume returning to the heart, which is consistent with hypovolemia. Lung congestion (Choice A) would be more indicative of fluid volume excess, not deficiency. Decreased hematocrit (Choice B) may be seen in conditions such as anemia but is not specific to deficient fluid volume. Increased blood pressure (Choice C) is not typically associated with deficient fluid volume; in fact, hypovolemia often leads to decreased blood pressure.

3. A nurse is preparing to administer insulin to a client with DM. The nurse understands that the peak time for rapid-acting insulin, such as lispro (Humalog), is:

• A. 30 minutes to 1 hour after administration.
• B. 1 to 2 hours after administration.
• C. 2 to 4 hours after administration.
• D. 3 to 5 hours after administration.

Correct answer: A

Rationale: The correct answer is A: 30 minutes to 1 hour after administration. Rapid-acting insulins like lispro, such as Humalog, peak quickly within 30 minutes to 1 hour after administration. This peak time is crucial to monitor for potential hypoglycemia, which is most likely to occur during this period. Choice B is incorrect as it suggests a longer peak time for rapid-acting insulin, which is inaccurate. Choices C and D are also incorrect because they indicate even longer peak times, which do not align with the rapid onset and peak action of lispro insulin.

4. A client with diabetes mellitus visits a health care clinic. The client's diabetes was previously well controlled with glyburide (Diabeta), 5 mg PO daily, but recently the fasting blood glucose has been running 180-200 mg/dl. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?

• A. Prednisone (Deltasone)
• B. Atenolol (Tenormin)
• C. Phenelzine (Nardil)
• D. Allopurinol (Zyloprim)

Correct answer: A

Rationale: Prednisone, a corticosteroid, can increase blood glucose levels by promoting gluconeogenesis and decreasing glucose uptake by cells. This medication can lead to hyperglycemia in patients, especially those with diabetes mellitus. Atenolol (Tenormin) is a beta-blocker and is not known to significantly affect blood glucose levels. Phenelzine (Nardil) is a monoamine oxidase inhibitor used to treat depression and anxiety disorders; it does not typically impact blood glucose levels. Allopurinol (Zyloprim) is a xanthine oxidase inhibitor used to manage gout and does not interfere with blood glucose regulation.

5. The client with type 2 DM is learning to manage blood glucose levels. When should the client monitor blood glucose?

• A. Only when feeling unwell.
• B. Only before meals.
• C. Before meals and at bedtime.
• D. Only after meals.

Correct answer: C

Rationale: The correct answer is to monitor blood glucose before meals and at bedtime. This timing allows the client to assess fasting levels and make informed decisions about mealtime insulin or medication doses. Monitoring only when feeling unwell (choice A) is not sufficient for proper glucose management as it may miss important trends. Monitoring only before meals (choice B) is helpful but does not provide a complete picture of the client's glucose control throughout the day. Monitoring only after meals (choice D) is less beneficial than monitoring before meals as it does not capture fasting levels. Therefore, monitoring before meals and at bedtime (choice C) is the most comprehensive approach to maintain good glucose control and prevent complications.
