Question

Mr. Reynolds is on the antithyroid drug (ATD) methimazole (Tapazole), so you make it a point to check his:

1) Glycated hemoglobin (HbA1c)
2) Complete blood count (CBC) and liver transaminases
3) Uric acid level
4) Total thyroxine (T4)

Answer 1

For Mr. Reynolds on methimazole, it is essential to monitor the Complete blood count (CBC) and liver transaminases to check for potential medication side effects such as liver toxicity and hematological changes.

Step-by-step explanation:

In reference to Mr. Reynolds who is on the antithyroid drug methimazole, the correct option to check is his Complete blood count (CBC) and liver transaminases. Methimazole is used for the treatment of hyperthyroidism. Hyperthyroidism is a condition in which the thyroid gland produces an excessive amount of thyroid hormones, such as thyroxine (T4) and triiodothyronine (T3).

While monitoring the levels of thyroid hormones is essential, it is just as important to monitor for potential side effects of the medication, which may include changes in blood count and liver function; hence, CBC and liver transaminases are essential tests. Methimazole can lead to liver toxicity and hematological changes, thus necessitating regular monitoring of these parameters.
