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 newborn who has a blood glucose level of 30 mg/dl. Which manifestation should the nurse expect?

• A. Loose stools.
• B. Jitteriness.
• C. Hypertonia.
• D. Abdominal distention.

Correct answer: B

Rationale: Jitteriness is a common symptom of neonatal hypoglycemia. When a newborn has a low blood glucose level, they may exhibit signs of central nervous system dysfunction, such as jitteriness. Loose stools (Choice A) are not typically associated with neonatal hypoglycemia. Hypertonia (Choice C) refers to increased muscle tone, which is not a common manifestation of hypoglycemia in newborns. Abdominal distention (Choice D) is more often associated with gastrointestinal issues rather than hypoglycemia.

3. A client who has a positive stool culture for Clostridium difficile should be placed in which type of room for infection control purposes?

• A. Wear a face shield prior to entering the room.
• B. Place the client in a private room.
• C. Place the client in a negative pressure room.
• D. Use an alcohol-based hand rub following client care.

Correct answer: B

Rationale: Placing the client in a private room is the appropriate infection control measure for C. difficile to prevent the spread of infection. While wearing a face shield may be necessary for procedures that generate splashes or sprays, it is not the primary precaution for C. difficile. Negative pressure rooms are typically used for airborne infections, not for C. difficile. Using an alcohol-based hand rub is important for hand hygiene but is not specific to managing C. difficile infection.

4. A nurse is caring for a client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse implement?

• A. Use a donut-shaped cushion for sitting
• B. Turn the client every 4 hours
• C. Elevate the head of the bed to 45 degrees
• D. Massage reddened areas to increase circulation

Correct answer: C

Rationale: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

5. A nurse is assessing a client who is receiving a continuous heparin infusion. Which of the following findings should the nurse report to the provider?

• A. Platelet count of 200,000/mm³
• B. aPTT of 50 seconds
• C. Hemoglobin of 14 g/dL
• D. INR of 1.0

Correct answer: D

Rationale: The correct answer is D because an INR of 1.0 is below the therapeutic range for clients receiving heparin, indicating a potential need for dosage adjustment. Platelet count (choice A) within normal range, aPTT (choice B) within therapeutic range, and hemoglobin level (choice C) are not directly related to the monitoring of heparin therapy and would not require immediate reporting to the provider.
