If a patient is prescribed medication 'qhs', when should they take it?

The abbreviation 'qhs' stands for "quaque hora somni," which is Latin for "every bedtime." This indicates that the medication should be taken at bedtime, specifically used for medications that are intended to assist with sleep or have effects that are most beneficial when taken at night. Therefore, the correct answer indicates that the patient should take the medication at the time they go to sleep.

Taking medication at bedtime is important because it ensures that the medication can work effectively during the night when it is needed most, aligning with the patient’s sleep cycle. This helps in managing the patient's symptoms or conditions that may require medication to be effective overnight.
