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 in an emergency department is assessing a client who reports ingesting thirty diazepam tablets. After securing the client's airway and initiating an IV, which of the following actions should the nurse do next?

• A. Monitor the client's IV site for thrombophlebitis.
• B. Administer flumazenil to the client.
• C. Evaluate the client for further suicidal behavior.
• D. Initiate seizure precautions for the client.

Correct answer: B

Rationale: Administering flumazenil is the priority to reverse the effects of diazepam overdose. Flumazenil is a specific benzodiazepine receptor antagonist that can rapidly reverse the sedative effects of diazepam. Monitoring the IV site for thrombophlebitis is important but not the immediate priority in this situation. Evaluating the client for further suicidal behavior is important for comprehensive care but is not the most urgent action at this moment. Initiating seizure precautions may be necessary, but the priority is to counteract the sedative effects of diazepam with flumazenil.

3. A nurse is assessing a newborn who is 12 hours old. Which of the following findings should the nurse report to the provider?

• A. Heart rate 140/min.
• B. A bulging anterior fontanel.
• C. Respiratory rate 50/min.
• D. Blood glucose 45 mg/dL.

Correct answer: D

Rationale: A blood glucose level of 45 mg/dL is below the normal range for a newborn and indicates hypoglycemia, which can lead to serious complications if left untreated. Therefore, this finding should be reported to the provider immediately. Choices A, B, and C are within normal ranges for a newborn and do not require immediate reporting. A heart rate of 140/min, a bulging anterior fontanel, and a respiratory rate of 50/min are all common findings in a newborn and do not raise immediate concerns.

4. A client with heart failure at risk for pulmonary edema should receive which intervention to improve oxygenation?

• A. Place the client in a supine position.
• B. Encourage the client to increase fluid intake.
• C. Elevate the client's legs when in bed.
• D. Administer oxygen via non-rebreather mask.

Correct answer: D

Rationale: Administering oxygen via a non-rebreather mask is the appropriate intervention for a client at risk for pulmonary edema as it helps improve oxygenation by delivering a high concentration of oxygen. Placing the client in a supine position can exacerbate pulmonary edema by increasing venous return to the heart, leading to fluid overload. Encouraging increased fluid intake is contraindicated in clients with heart failure and at risk for pulmonary edema, as it can worsen fluid accumulation. Elevating the client's legs when in bed is more appropriate for clients with conditions such as venous insufficiency or edema in the lower extremities, not for pulmonary edema.

5. 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.
