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 caring for a client who has severe preeclampsia and is receiving magnesium sulfate intravenously. The nurse discontinues the magnesium sulfate after the client displays toxicity. Which of the following actions should the nurse take?

• A. Position the client supine.
• B. Prepare an IV bolus of dextrose 5% in water.
• C. Administer methylergonovine IM.
• D. Administer calcium gluconate IV.

Correct answer: D

Rationale: Administering calcium gluconate IV is the correct action when a client displays toxicity from magnesium sulfate. Calcium gluconate is used as the antidote for magnesium sulfate toxicity as it counteracts the effects. Positioning the client supine (Choice A) is not the immediate action needed. Administering dextrose 5% in water (Choice B) is not indicated for magnesium sulfate toxicity. Administering methylergonovine IM (Choice C) is used in postpartum hemorrhage, not for magnesium sulfate toxicity.

3. How should a healthcare professional manage a patient with hypertension who is non-compliant with medication?

• A. Provide education on the importance of medication
• B. Refer the patient to a specialist
• C. Discontinue the medication
• D. Explore alternative treatment options

Correct answer: A

Rationale: Providing education on the importance of medication is crucial in managing hypertension in patients who are non-compliant. By educating the patient about the significance of taking medication as prescribed, the healthcare professional can help improve the patient's understanding and motivation to adhere to the treatment plan. Referring the patient to a specialist (Choice B) may be necessary in some cases but addressing non-compliance should start with education. Discontinuing the medication (Choice C) without addressing the root cause of non-compliance can worsen the patient's condition. Exploring alternative treatment options (Choice D) should come after ensuring the patient understands the importance of the current treatment regimen.

4. A nurse is planning discharge teaching about cord care for the parents of a newborn. Which of the following instructions should the nurse include?

• A. The cord stump will fall off in 5 days.
• B. Contact the provider if the cord stump turns black.
• C. Clean the base of the cord with hydrogen peroxide daily.
• D. Keep the cord stump dry until it falls off.

Correct answer: D

Rationale: The correct instruction for cord care is to keep the cord stump dry until it falls off. This helps prevent infection and promotes healing. Choice A is incorrect because the timing of when the cord stump falls off can vary, usually between 1-3 weeks. Choice B is incorrect as a black cord stump can be a normal part of the healing process, so it is unnecessary to contact the provider for this reason. Choice C is incorrect because cleaning the cord with hydrogen peroxide daily is not recommended as it can delay healing and cause irritation.

5. A nurse is caring for a client who is postoperative following a total knee arthroplasty. Which of the following actions should the nurse take?

• A. Place a pillow under the client's knees
• B. Keep the client's legs elevated
• C. Flex the client's knee every 2 hours
• D. Apply heat to the operative knee

Correct answer: B

Rationale: Keeping the client's legs elevated is the appropriate action to prevent venous thromboembolism following a total knee arthroplasty. Elevating the legs helps promote circulation and reduce the risk of blood clots. Placing a pillow under the client's knees may provide comfort but does not address the specific postoperative complication. Flexing the client's knee every 2 hours may be contraindicated as excessive movement can disrupt the surgical site. Applying heat to the operative knee is not recommended immediately postoperatively as it can increase swelling and discomfort.
