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 preparing to administer a unit of packed RBCs to a client. Which of the following actions should the nurse take first?

• A. Check the client's identification band
• B. Verify the provider's prescription
• C. Prime the IV tubing with 0.9% sodium chloride
• D. Obtain the client's vital signs

Correct answer: A

Rationale: The correct first action for the nurse to take when preparing to administer a unit of packed RBCs is to check the client's identification band. This step is crucial to ensure that the correct blood is administered to the right client, preventing any errors or adverse reactions. Verifying the provider's prescription, priming the IV tubing, and obtaining the client's vital signs are important steps in the process but should follow the initial identification check to prioritize patient safety.

3. A nurse is reviewing the medical record of a client who has a new prescription for enalapril. Which of the following findings should the nurse report to the provider?

• A. Serum potassium 4.0 mEq/L
• B. Sodium 138 mEq/L
• C. Serum creatinine 3.8 mg/dL
• D. Hemoglobin 13 g/dL

Correct answer: C

Rationale: The correct answer is C. An elevated serum creatinine level can indicate impaired kidney function, which is crucial to report before administering enalapril. Enalapril, an ACE inhibitor, can affect kidney function, especially in patients with pre-existing renal impairment. Choices A, B, and D are within normal ranges and do not directly impact the initiation of enalapril therapy.

4. A client is being discharged with a new prescription for levothyroxine. Which of the following instructions should the nurse include?

• A. Take this medication with meals to avoid stomach upset.
• B. Take this medication at the same time every day.
• C. Notify your provider if you experience chest pain or palpitations.
• D. Take this medication with antacids to reduce indigestion.

Correct answer: B

Rationale: The correct answer is B: 'Take this medication at the same time every day.' It is crucial to take levothyroxine at the same time each day to maintain consistent thyroid hormone levels. Choice A is incorrect because levothyroxine should be taken on an empty stomach, usually in the morning. Choice C is important but not specific to the administration of levothyroxine. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.

5. A nurse is reviewing the medical record of a client who has a history of myocardial infarction. Which of the following findings should the nurse report to the provider?

• A. Blood pressure 140/90 mm Hg
• B. Heart rate of 88/min
• C. LDL cholesterol 110 mg/dL
• D. Respiratory rate of 16/min

Correct answer: D

Rationale: In a client with a history of myocardial infarction, a respiratory rate of 16/min should be reported to the provider. Changes in respiratory rate can indicate cardiac or pulmonary issues that need further evaluation. The other vital signs provided (blood pressure, heart rate, and LDL cholesterol level) are within normal limits and do not directly relate to potential complications following a myocardial infarction.
