NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

Labetalol is considered the drug of choice for pregnant patients. This is because Labetalol is a safe and effective option for managing high blood pressure during pregnancy, compared to other medications which may have potential risks for the developing baby. Additionally, the other options listed - such as using Labetalol in the elderly, teenagers, or patients with liver disease - may not necessarily be incorrect or unacceptable, but they are not the preferred choice due to factors such as potential interactions with other medications, increased side effects, or potential risks for certain populations. Therefore, while Labetalol may still be a suitable option for these patient populations, it is not considered the "drug of choice" for their conditions.
