Nursing Elites

1. A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin (A1C)
• C. Urine output
• D. Serum ketone level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.

2. An older client with SIRS has a temperature of 101.8°F, a heart rate of 110 beats per minute, and a respiratory rate of 24 breaths per minute. Which additional finding is most important to report to the healthcare provider?

• A. Serum creatinine of 2.0 mg/dL
• B. Elevated WBC count
• C. Blood pressure of 100/60 mmHg
• D. Oxygen saturation of 95%

Correct answer: A

Rationale: A serum creatinine level of 2.0 mg/dL indicates possible acute kidney injury, which can occur during severe systemic inflammatory response syndrome (SIRS). Reporting this value promptly allows for interventions to prevent further renal damage. Elevated WBC count (choice B) is a common feature of SIRS and may not be as urgently indicative of immediate organ damage as high creatinine levels. A blood pressure of 100/60 mmHg (choice C) is relatively low but may be a typical finding in SIRS; however, renal function is critical in this context. Oxygen saturation of 95% (choice D) is within normal limits and is not as concerning as a high creatinine level in this scenario.

3. The nurse is caring for a client with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Which intervention is most important for the nurse to implement?

• A. Encourage oral hydration
• B. Monitor for signs of dehydration
• C. Restrict fluid intake
• D. Administer IV fluids as prescribed

Correct answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.

4. A client with hyperparathyroidism is preparing for surgery. Which preoperative lab finding is most important to report?

• A. Elevated serum calcium.
• B. Decreased serum albumin.
• C. Elevated serum potassium.
• D. Elevated serum magnesium.

Correct answer: A

Rationale: The correct answer is A: Elevated serum calcium. In hyperparathyroidism, elevated calcium levels can lead to complications such as kidney stones, bone pain, and fractures. During surgery, high calcium levels can affect neuromuscular function, cardiac function, and blood clotting. Therefore, it is crucial to report elevated serum calcium levels preoperatively to prevent potential surgical complications. Choices B, C, and D are not directly associated with hyperparathyroidism and are less likely to impact the surgical outcome in this scenario.

5. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.
