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 assessing a client who has heart failure and is receiving furosemide. Which of the following findings should the nurse identify as an indication that the client is developing hypokalemia?

• A. Positive Trousseau's sign.
• B. Hyperactive reflexes.
• C. Hypoactive bowel sounds.
• D. Decreased deep-tendon reflexes.

Correct answer: A

Rationale: The correct answer is A: Positive Trousseau's sign. When a patient receiving furosemide is developing hypokalemia, they may exhibit a positive Trousseau's sign, an indication of low potassium levels. This sign is elicited by inflating a blood pressure cuff above systolic pressure for a few minutes, resulting in carpal spasm. Choices B, C, and D are incorrect. Hyperactive reflexes are associated with hyperkalemia, not hypokalemia. Hypoactive bowel sounds are not specifically related to hypokalemia. Decreased deep-tendon reflexes are not typically seen in hypokalemia.

3. A nurse is preparing to administer digoxin to a client who has heart failure. Which of the following findings should the nurse report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Heart rate of 60/min
• D. Sodium 140 mEq/L

Correct answer: C

Rationale: The correct answer is C: Heart rate of 60/min. A heart rate of 60/min is borderline bradycardia, which can be a sign of digoxin toxicity. Digoxin can cause bradycardia, so any further decrease in heart rate should be reported promptly to the healthcare provider. Choices A, B, and D are within the normal range and not specifically related to potential digoxin toxicity, so they do not require immediate reporting.

4. A nurse is teaching a client who has a new prescription for alendronate. Which of the following instructions should the nurse include in the teaching?

• A. Take this medication at bedtime.
• B. Take this medication with food.
• C. Remain upright for at least 30 minutes after taking this medication.
• D. Avoid taking this medication with calcium-rich foods.

Correct answer: C

Rationale: The correct answer is C: 'Remain upright for at least 30 minutes after taking this medication.' This instruction is crucial when taking alendronate as it reduces the risk of esophagitis by preventing the medication from irritating the esophagus. Choice A is incorrect because alendronate should be taken in the morning, not at bedtime, to enhance absorption. Choice B is incorrect as alendronate should be taken on an empty stomach, preferably in the morning, with a full glass of water. Choice D is incorrect as there are no specific restrictions on taking alendronate with calcium-rich foods.

5. A client has a chest tube. Which of the following interventions should the nurse include?

• A. Clamp the chest tube for 15 minutes every 2 hours.
• B. Maintain the drainage system below the client's chest.
• C. Strip the chest tube every 2 hours.
• D. Keep the collection device at the level of the client's chest.

Correct answer: B

Rationale: Maintaining the chest tube drainage system below the client's chest level is crucial to ensure proper drainage and prevent complications. Clamping the chest tube can lead to a tension pneumothorax, stripping the chest tube is an outdated practice that can cause damage to the tissues, and keeping the collection device at the level of the client's chest can impede proper drainage and lead to fluid accumulation.
