Nursing Elites

1. What is the lowest fasting plasma glucose level suggestive of a diagnosis of DM?

• A. 90 mg/dl.
• B. 115 mg/dl.
• C. 126 mg/dl.
• D. 180 mg/dl.

Correct answer: C

Rationale: A fasting plasma glucose level of 126 mg/dl or higher is diagnostic of diabetes mellitus. Choice A (90 mg/dl) is too low to indicate diabetes. Choice B (115 mg/dl) is also below the diagnostic threshold for diabetes. Choice D (180 mg/dl) is above the diagnostic threshold and would indicate uncontrolled diabetes, not the lowest level suggestive of a diagnosis.

2. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?

• A. Adrenal cortex
• B. Pancreas
• C. Adrenal medulla
• D. Parathyroid

Correct answer: A

Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not 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 type 2 diabetes mellitus is being discharged after receiving initial treatment. What should the nurse emphasize as a crucial instruction?

• A. Take insulin as prescribed, even if you are not eating.
• B. Avoid all forms of physical exercise to prevent hypoglycemia.
• C. Monitor blood glucose levels regularly and report any changes.
• D. Stop taking oral antidiabetic medication if your blood glucose levels are normal.

Correct answer: C

Rationale: Monitoring blood glucose levels regularly is a critical aspect of managing type 2 diabetes mellitus. This allows the individual to track their blood sugar levels, understand the effectiveness of the treatment plan, and detect any fluctuations promptly. Option A is incorrect because insulin should be taken based on a prescribed schedule that correlates with meals to prevent hypoglycemia or hyperglycemia. Option B is incorrect as physical exercise is beneficial for managing diabetes but should be done cautiously with adjustments in insulin or food intake. Option D is incorrect because discontinuing oral antidiabetic medications without healthcare provider guidance can lead to uncontrolled blood glucose levels.

5. The client with DM is being taught by the nurse about the importance of monitoring blood glucose levels. The nurse should instruct the client to:

• A. Check blood glucose only when feeling unwell.
• B. Check blood glucose before meals and at bedtime.
• C. Check blood glucose only after meals.
• D. Check blood glucose only in the morning.

Correct answer: B

Rationale: The correct answer is to check blood glucose before meals and at bedtime. Monitoring blood glucose levels before meals allows the client to adjust their insulin or oral antidiabetic medications based on their current levels. Checking at bedtime helps in ensuring blood glucose levels are at a safe range throughout the night. Option A is incorrect because blood glucose should be monitored regularly as part of diabetes management, not just when feeling unwell. Option C is incorrect because checking only after meals does not provide a complete picture of blood glucose control throughout the day. Option D is incorrect as checking only in the morning does not cover the full spectrum of blood glucose variations that can occur during the day.
