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 healthcare professional is receiving a telephone prescription from a provider for a client who requires additional medication for pain control. Which of the following entries should the professional make in the medical record?

• A. Morphine 3 mg SC every 4 hr. PRN for pain
• B. Morphine 3 mg Subcutaneous
• C. Morphine 3.0 mg subq every 4 hr. PRN for pain
• D. Morphine 3 mg SC q 4 hr. PRN for pain

Correct answer: A

Rationale: The correct entry for the medication in the medical record should include the abbreviation 'SC' (subcutaneous) for the route of administration. Choice A is the correct answer as it accurately represents the prescription received. Choice B is incorrect because it lacks the frequency and PRN indication. Choice C is incorrect due to the incorrect abbreviation 'subq' and the missing 'q' before the frequency. Choice D is incorrect because it uses 'SC' but the frequency abbreviation 'q' should be followed by the time interval.

3. What should be monitored when administering opioids to a patient?

• A. Monitor blood pressure
• B. Monitor respiratory rate
• C. Monitor heart rate
• D. Monitor oxygen saturation

Correct answer: B

Rationale: When administering opioids, monitoring the respiratory rate is crucial to detect any signs of respiratory depression, which is a serious side effect of opioid use. Monitoring blood pressure, heart rate, and oxygen saturation are important parameters to assess a patient's overall condition, but they are not the primary focus when administering opioids.

4. A nurse is planning care for a client who has a closed head injury and has an intraventricular catheter. Which of the following interventions should the nurse include to reduce the risk for infection?

• A. Keep the head of the bed elevated to 30 degrees.
• B. Administer IV antibiotics prophylactically.
• C. Change the catheter insertion site every 24 hours.
• D. Monitor the insertion site for redness.

Correct answer: D

Rationale: The correct answer is to monitor the insertion site for redness. This intervention helps detect signs of infection early in clients with intraventricular catheters. Keeping the head of the bed elevated to 30 degrees is important for managing intracranial pressure but does not directly reduce the risk of infection. Administering IV antibiotics prophylactically is not recommended as a routine practice due to the risk of antibiotic resistance and should only be done based on culture results. Changing the catheter insertion site every 24 hours is unnecessary and increases the risk of introducing new pathogens.

5. A nurse is caring for a client who has an indwelling urinary catheter. Which of the following interventions should the nurse implement to prevent catheter-associated infections?

• A. Change the catheter every 24 hours
• B. Ensure the drainage bag is positioned above the bladder
• C. Perform routine irrigation of the catheter
• D. Empty the drainage bag every 4 hours

Correct answer: B

Rationale: The correct answer is to ensure the drainage bag is positioned above the bladder. This positioning prevents urine reflux into the bladder, reducing the risk of catheter-associated infections. Changing the catheter too frequently (Choice A) can actually increase the risk of infection by introducing pathogens. Performing routine catheter irrigation (Choice C) is no longer recommended as it can increase the risk of infection by introducing bacteria. Emptying the drainage bag every 4 hours (Choice D) is a standard practice to prevent urinary stasis but is not directly related to preventing catheter-associated infections.
