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 is in active labor and notes the FHR baseline has been 100/min for the past 15 minutes. The nurse should identify which of the following conditions as a possible cause of fetal bradycardia?

• A. Maternal fever.
• B. Fetal anemia.
• C. Maternal hypoglycemia.
• D. Chorioamnionitis.

Correct answer: C

Rationale: In this scenario, the fetal heart rate (FHR) baseline of 100/min for the past 15 minutes indicates bradycardia. Maternal hypoglycemia can lead to decreased oxygen supply to the fetus, resulting in fetal bradycardia. This situation requires immediate intervention to address the underlying cause. Choices A, B, and D are incorrect as they are not typically associated with fetal bradycardia. Maternal fever, fetal anemia, and chorioamnionitis may have other effects on the fetus but are not primary causes of bradycardia in this context.

3. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following actions should the nurse take to prevent infection?

• A. Change the TPN tubing every 48 hours.
• B. Change the TPN tubing every 24 hours.
• C. Monitor the client's urine output every 8 hours.
• D. Monitor the client's weight every 72 hours.

Correct answer: B

Rationale: The correct answer is to change the TPN tubing every 24 hours. This action helps reduce the risk of infection because the high glucose content of TPN promotes bacterial growth. Choice A is incorrect as changing the tubing every 48 hours would not provide adequate infection prevention. Option C, monitoring urine output, is important for assessing renal function but is not directly related to preventing TPN-related infections. Option D, monitoring weight, is essential for assessing nutritional status but does not directly address infection prevention in TPN administration.

4. A nurse is caring for a client who has pneumonia. Which of the following findings should the nurse report to the provider?

• A. Productive cough with green sputum
• B. Temperature of 37.1°C (98.8°F)
• C. Crackles in the lung bases
• D. Oxygen saturation of 95%

Correct answer: C

Rationale: In a client with pneumonia, crackles in the lung bases can indicate fluid accumulation, worsening of the condition, or development of complications such as pulmonary edema. This finding should be reported to the provider promptly for further evaluation and management. Choices A, B, and D are common in clients with pneumonia and may not necessarily require immediate reporting unless accompanied by other concerning symptoms or vital sign abnormalities.

5. How should a healthcare professional assess for infection in a patient post-surgery?

• A. Check the surgical site
• B. Check for fever
• C. Check for abnormal breath sounds
• D. Check the patient's skin color

Correct answer: A

Rationale: When assessing for infection in a patient post-surgery, checking the surgical site is crucial. Changes in the appearance of the surgical site, such as redness, swelling, warmth, or drainage, can indicate an infection. While checking for fever (Choice B) is also important as it can be a sign of infection, it is a more general symptom and may not always be present. Checking for abnormal breath sounds (Choice C) and skin color (Choice D) are not typically direct indicators of infection in a post-surgery patient.
