Nursing Elites

1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

2. A nurse is reviewing the laboratory results of a client who has Cushing's disease. The nurse should expect an increase in which of the following laboratory values?

• A. Serum glucose level
• B. Serum potassium level
• C. Serum calcium level
• D. Serum sodium level

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is increased cortisol production, leading to elevated blood glucose levels. This occurs due to the role of cortisol in promoting gluconeogenesis and insulin resistance. Choices B, C, and D are incorrect because Cushing's disease is not typically associated with alterations in serum potassium, calcium, or sodium levels.

3. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

4. A nurse is caring for a client who has a prescription for furosemide. Which of the following findings should the nurse identify as an indication that the medication is effective?

• A. Weight loss of 0.5 kg (1.1 lb) in 24 hours.
• B. Increased urinary output.
• C. Blood pressure of 118/78 mm Hg.
• D. Decreased peripheral edema.

Correct answer: A

Rationale: The correct answer is A. Weight loss of 0.5 kg (1.1 lb) in 24 hours is an indication that furosemide is effectively reducing fluid retention. This medication works by promoting diuresis, resulting in increased urine output, which could lead to weight loss. While increased urinary output (choice B) is a common effect of furosemide, weight loss is a more specific indicator of its effectiveness. Blood pressure (choice C) and decreased peripheral edema (choice D) can be influenced by various factors and are not direct indicators of furosemide's effectiveness in reducing fluid retention.

5. During a change-of-shift report, a nurse is receiving information about an adult female client who is postoperative. Which of the following client information should the nurse report?

• A. The client's oxygen saturation is 95%
• B. The client's blood pressure is 110/70 mm Hg
• C. The client has a temperature of 36.8°C (98.2°F)
• D. The client's heart rate is 88/min

Correct answer: B

Rationale: The correct answer is B because a blood pressure of 110/70 mm Hg is within the normal range and stable. Reporting this information is crucial to monitor the client's condition postoperatively. Oxygen saturation of 95% is acceptable, a temperature of 36.8°C (98.2°F) is normal, and a heart rate of 88/min is within the expected range for an adult female client, so these values do not raise concerns that require immediate reporting.
