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 client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

3. A client with acute diverticulitis should have which intervention included in the care plan?

• A. Administer a cleansing enema.
• B. Initiate a low-fiber diet.
• C. Apply moist heat to the abdomen.
• D. Provide a clear liquid diet.

Correct answer: B

Rationale: The correct intervention for a client with acute diverticulitis is to initiate a low-fiber diet. A low-fiber diet helps manage acute diverticulitis by reducing irritation to the colon, allowing it to heal. Administering a cleansing enema (Choice A) can worsen diverticulitis by increasing pressure within the colon. Applying moist heat to the abdomen (Choice C) may provide comfort but does not address the underlying cause. Providing a clear liquid diet (Choice D) is not ideal for diverticulitis management as it lacks the necessary nutrients for healing and may not provide enough bulk to prevent further irritation.

4. A nurse is assessing a client who is experiencing acute pain. Which of the following manifestations should the nurse expect?

• A. Hypertension
• B. Bradycardia
• C. Diaphoresis
• D. Piloerection

Correct answer: C

Rationale: The correct answer is C: Diaphoresis. Diaphoresis, which is excessive sweating, is a common manifestation of acute pain caused by increased sympathetic nervous system activity. This response is the body's way of trying to regulate body temperature during the stress response. Choices A, B, and D are incorrect. Hypertension (Choice A) and tachycardia (not bradycardia as in Choice B) are more likely responses to acute pain due to sympathetic nervous system activation. Piloerection (Choice D), also known as goosebumps, is not a typical manifestation of acute pain.

5. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Take the medication with food to prevent stomach upset.
• C. Take one tablet every 5 minutes, up to three doses, for chest pain.
• D. Swallow the tablet whole for the best effect.

Correct answer: C

Rationale: The correct instruction for a client with a new prescription for nitroglycerin sublingual tablets is to take one tablet every 5 minutes, up to three doses, for chest pain. This dosing regimen helps relieve chest pain associated with angina by promoting vasodilation. Option A is incorrect as nitroglycerin sublingual tablets should be placed under the tongue, not swallowed with water. Option B is incorrect because taking nitroglycerin with food may decrease its effectiveness. Option D is incorrect because nitroglycerin sublingual tablets are meant to be dissolved under the tongue, not swallowed whole.
