Mr. Ramos consulted at the health center for follow up after one month of Isoniazid and Rifampicin. Which diagnostic test will have an abnormal result if the client is taking these medications?
Correct Answer: C
Rationale: The client is taking Isoniazid and Rifampicin, which are two common first-line medications prescribed for the treatment of tuberculosis. Both of these drugs can potentially cause liver toxicity as a side effect. Therefore, the diagnostic test that is most likely to have an abnormal result if the client is taking these medications is the liver function tests. These tests include parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and bilirubin levels, which can indicate liver damage or dysfunction. Monitoring liver function is essential during treatment with these medications to detect any hepatic adverse effects early and make appropriate management decisions.
