How frequently is a medication administered if prescribed "every day"?

When a medication is prescribed to be taken "every day," it indicates that the patient should take the medication once per day, without any gaps or interruptions. This frequency ensures that the medication maintains a consistent presence in the patient's system for its intended therapeutic effect.

The term "每天," which translates to "every day," clearly conveys the requirement to adhere to a daily schedule for taking the medication. Consistency is vital for many medications to achieve the desired health outcomes, so it is essential that the patient follows this directive closely.

The other options suggest varying frequencies that do not align with the "every day" prescription. For instance, "once weekly" indicates a much less frequent administration, which would not provide the continuous support that a daily prescription aims to achieve. Similarly, "every other day" and "every two days" suggest even less frequent intervals, making them incompatible with the directive of "every day." Therefore, "每天" is the only accurate interpretation of the prescribed frequency.
