A client receives a tuberculin (PPD) skin test on Thursday at 1200. The nurse documents on the medication record that the results need to be read:
Sunday morning
Saturday morning
Friday morning
Monday morning
The Correct Answer is A
The tuberculin skin test (TST), also known as the Mantoux test, is used to determine if a person has been infected with the tuberculosis (TB) bacteria. The test involves injecting a small amount of purified protein derivative (PPD) into the skin of the forearm. The injection site is then examined 48 to 72 hours later for a reaction, which is measured in millimeters of induration (swelling).
Choice A reason:
Sunday morning is the correct time to read the test results. Since the test was administered on Thursday at 1200, the 48 to 72-hour window for reading the results would fall between Saturday at 1200 and Monday at 1200. Reading the results on Sunday morning falls within this time frame, making it the appropriate choice.
Choice B reason:
Saturday morning is not the correct time to read the test results. Reading the test results on Saturday morning would be less than 48 hours after the test was administered, which is too early to accurately assess the reaction. The test needs to be read between 48 and 72 hours after administration to ensure accurate results.
Choice C reason:
Friday morning is also not the correct time to read the test results. Reading the test results on Friday morning would be only 24 hours after the test was administered, which is far too early. The immune response to the PPD injection takes time to develop, and reading the test too early can result in a false-negative result.
Choice D reason:
Monday morning is within the acceptable time frame to read the test results, but it is at the very end of the 72-hour window. While it is still technically correct, it is generally recommended to read the test closer to the 48-hour mark to ensure the most accurate results. Therefore, Sunday morning is a better choice.

Correct Answer is A
Explanation
Clients on tuberculosis (TB) medications, particularly those on isoniazid, rifampin, and pyrazinamide, are at risk for hepatotoxicity. Therefore, regular monitoring of liver function tests (LFTs) is crucial to detect any liver damage early and adjust treatment as necessary.
Choice A reason:
Liver function studies are essential for clients on TB medications. Drugs like isoniazid, rifampin, and pyrazinamide can cause liver toxicity. Monitoring liver enzymes such as ALT (alanine aminotransferase) and AST (aspartate aminotransferase) helps in early detection of hepatotoxicity, allowing for timely intervention to prevent severe liver damage. Regular LFTs ensure that any adverse effects on the liver are identified and managed promptly.
Choice B reason:
White blood cells (WBCs) are not typically monitored monthly for clients on TB medications. While WBC counts can be affected by various conditions and treatments, they are not specifically indicative of the side effects of TB medications. Monitoring WBCs might be necessary if there are signs of infection or other hematologic issues, but it is not a standard monthly requirement for TB treatment.
Choice C reason:
Coagulation studies are not routinely required for clients on TB medications. These tests are more relevant for patients on anticoagulant therapy or those with bleeding disorders. TB medications do not typically affect coagulation parameters, so regular monitoring of coagulation studies is not necessary unless there is a specific clinical indication.
Choice D reason:
Red blood cells (RBCs) are also not typically monitored monthly for clients on TB medications. While anemia can occur in TB patients, it is not a direct side effect of the medications used to treat TB. Monitoring RBCs might be necessary if there are symptoms of anemia or other hematologic concerns, but it is not a standard part of monthly TB treatment monitoring.
Correct Answer is D
Explanation
Choice A reason:
Administering inhaler medications and increasing oxygen may be necessary if the client is experiencing respiratory distress. However, since the client is not currently reporting increased dyspnea, this intervention is not immediately required. The focus should be on addressing the client’s anxiety.
Choice B reason:
Notifying the physician and administering lorazepam may be appropriate if the client’s anxiety is severe and not manageable through non-pharmacological means. However, it is generally best to try comfort measures and non-pharmacological interventions first.
Choice C reason:
Dimming the lights and encouraging the client to take a nap can help reduce anxiety, but it may not be the most effective initial intervention. Providing direct comfort and reassurance is often more beneficial in addressing immediate anxiety.
Choice D reason:
Sitting with the client and providing comfort measures is the most appropriate intervention. This approach helps to alleviate anxiety through direct support and reassurance. Techniques such as deep breathing exercises, talking calmly, and providing a comforting presence can significantly reduce anxiety.
