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 client who has pneumonia. Which of the following findings should the nurse report to the provider?

• A. Crackles in the lung bases
• B. Oxygen saturation of 95%
• C. Heart rate of 88/min
• D. Frequent productive cough

Correct answer: A

Rationale: The correct answer is A: Crackles in the lung bases. In a client with pneumonia, crackles in the lung bases can indicate fluid accumulation, suggesting worsening respiratory status. This finding should be reported to the provider for further evaluation and management. Choice B, an oxygen saturation of 95%, is within the normal range and does not require immediate reporting. Choice C, a heart rate of 88/min, is also within normal limits and does not indicate an urgent need for intervention. Choice D, a frequent productive cough, is a common symptom in pneumonia and may not require immediate reporting unless it is severe or worsening. Therefore, crackles in the lung bases are the most concerning finding that warrants prompt attention.

3. A nurse is caring for a client who has cirrhosis and a new prescription for lactulose. The nurse should monitor the client for which of the following therapeutic effects of this medication?

• A. Improved mental status.
• B. Increased urine output.
• C. Decreased serum ammonia.
• D. Decreased bilirubin levels.

Correct answer: C

Rationale: The correct answer is C: Decreased serum ammonia. Lactulose is prescribed to decrease serum ammonia levels in clients with cirrhosis and hepatic encephalopathy. By reducing serum ammonia, lactulose helps improve the mental status of these clients. Therefore, monitoring for decreased serum ammonia is crucial to assess the effectiveness of lactulose therapy. Choice A (Improved mental status) is indirectly related as it is the desired outcome of decreasing ammonia levels. Choices B (Increased urine output) and D (Decreased bilirubin levels) are not directly associated with the therapeutic effects of lactulose in cirrhosis and hepatic encephalopathy.

4. A healthcare provider is reviewing laboratory results for a client who has diabetes mellitus. Which of the following tests is an indicator of long-term blood glucose control?

• A. Fasting blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Random blood glucose
• D. Postprandial blood glucose

Correct answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

5. What is the appropriate intervention for a patient with hypertension refusing medication?

• A. Educate the patient on the importance of medication
• B. Respect the patient's decision
• C. Inform the healthcare provider
• D. Explore alternative treatment options

Correct answer: A

Rationale: The correct answer is A: Educate the patient on the importance of medication. Providing education to the patient is crucial in promoting understanding of the condition and the necessity of medication. By enhancing the patient's knowledge, healthcare providers can empower them to make informed decisions regarding their health. Choice B, respecting the patient's decision, may not be appropriate in this scenario as untreated hypertension can lead to serious complications. Choice C, informing the healthcare provider, is important but should be done after attempting to educate the patient. Choice D, exploring alternative treatment options, may be considered if the patient has concerns or side effects related to the medication, but initially, educating the patient about the importance of medication is key.
