Nursing Elites

1. The patient expects that a type 1 diabetic may receive ____ of their morning dose of insulin preoperatively:

• A. 10-20%.
• B. 25-40%.
• C. 50-60%.
• D. 85-90%.

Correct answer: B

Rationale: It is common practice to administer 25-40% of the morning dose of insulin preoperatively to prevent hypoglycemia during surgery. Giving a lower percentage (A) may not provide sufficient glycemic control, while higher percentages (C, D) can increase the risk of hypoglycemia during the surgical procedure.

2. A client with hyperthyroidism is prescribed propranolol. The nurse understands that this medication is used to:

• A. Increase metabolism
• B. Reduce anxiety
• C. Decrease heart rate
• D. Increase blood pressure

Correct answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

3. A male client with type 1 diabetes mellitus has a highly elevated glycosylated hemoglobin (Hb) test result. In discussing the result with the client, nurse Sharmaine would be most accurate in stating:

• A. The test needs to be repeated following a 12-hour fast.
• B. It appears you aren't following the prescribed diabetic diet.
• C. It tells us about your sugar control for the last 3 months.
• D. Your insulin regimen needs to be significantly altered.

Correct answer: C

Rationale: The correct answer is C. Glycosylated hemoglobin (HbA1c) reflects average blood glucose levels over the past 3 months. This test is used to assess long-term blood sugar control in individuals with diabetes. Choice A is incorrect because fasting is not required for an HbA1c test. Choice B is judgmental and not supported by the information provided. Choice D is not the most accurate statement to make based on the HbA1c result; adjusting insulin would depend on a more comprehensive assessment of the client's overall diabetes management.

4. Which of the following laboratory values should the nurse monitor in a client with Cushing's syndrome?

• A. Blood glucose levels
• B. Serum calcium levels
• C. Serum potassium levels
• D. Serum sodium levels

Correct answer: A

Rationale: The correct answer is A: Blood glucose levels. In Cushing's syndrome, there is excess cortisol in the body which leads to increased blood glucose levels due to its effect on glucose metabolism. Elevated blood glucose levels are a common finding in individuals with Cushing's syndrome. Monitoring blood glucose levels is crucial as it helps in assessing and managing hyperglycemia in these patients. Choice B, serum calcium levels, is not typically a priority in monitoring for Cushing's syndrome. While abnormalities in calcium levels can occur in some endocrine disorders, hypercalcemia is not a hallmark of Cushing's syndrome. Choice C, serum potassium levels, and Choice D, serum sodium levels, are not directly associated with Cushing's syndrome. While electrolyte imbalances can occur in various conditions, they are not specifically linked to Cushing's syndrome as blood glucose levels are.

5. The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

• A. Weight loss
• B. Flat neck and hand veins
• C. An increase in blood pressure
• D. A decreased central venous pressure (CVP)

Correct answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.
