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 planning care for a client who has a new prescription for total parenteral nutrition (TPN). Which of the following interventions should the nurse include?

• A. Weigh the client weekly to monitor for fluid retention.
• B. Monitor the client's blood glucose level every 6 hours.
• C. Change the TPN tubing every 72 hours.
• D. Flush the TPN line with sterile water before and after administration.

Correct answer: B

Rationale: The correct answer is B: Monitor the client's blood glucose level every 6 hours. When a client is on TPN, it is crucial to monitor their blood glucose levels frequently to prevent complications such as hyperglycemia or hypoglycemia. Weighing the client weekly to monitor for fluid retention (choice A) is important but not as critical as monitoring blood glucose levels. Changing the TPN tubing every 72 hours (choice C) is important for infection control but does not directly relate to the client's metabolic status. Flushing the TPN line with sterile water before and after administration (choice D) is not a standard practice and may introduce contaminants into the TPN solution.

3. What is the best intervention for a patient experiencing respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Administer IV fluids
• D. Provide humidified air

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient experiencing respiratory distress because it helps improve oxygenation and alleviate respiratory distress. Oxygen therapy is a critical and priority intervention in such cases as it aims to increase oxygen levels in the blood. Administering bronchodilators may be beneficial for specific respiratory conditions like asthma or COPD, but oxygen should be the initial priority. Administering IV fluids and providing humidified air, while important in certain situations, are not the primary interventions for respiratory distress.

4. Which medication is used to reverse the effects of opioid overdose?

• A. Naloxone
• B. Epinephrine
• C. Atropine
• D. Lidocaine

Correct answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.

5. A client is postoperative following cataract surgery. Which of the following instructions should the nurse include?

• A. Avoid lying flat for 24 hours after surgery.
• B. Avoid bending at the waist.
• C. Wear an eye patch at night for 1 week.
• D. Sleep on your affected side to reduce discomfort.

Correct answer: B

Rationale: The correct instruction that the nurse should include for a client postoperative following cataract surgery is to avoid bending at the waist. Bending at the waist can increase intraocular pressure, which is not recommended after cataract surgery. Choices A, C, and D are incorrect because lying flat for 24 hours after surgery may not be necessary, wearing an eye patch at night for a week is not a standard postoperative instruction for cataract surgery, and sleeping on the affected side may not necessarily reduce discomfort and can increase pressure on the eye.
