Question 68

h.s. refers to a specific time of day.

The abbreviation h.s. on a prescription indicates that the medication should be taken at bedtime or "hora somni," which translates to "at the hour of sleep." This is specifically related to the timing of medication administration.

A) time of day.

This option is correct because h.s. specifically means to take the medication at bedtime. The instruction is related to the timing rather than any other aspect of medication use.

B) dosage form.

This option is incorrect as h.s. does not refer to the form in which a medication is delivered, such as tablet, capsule, or liquid. Dosage forms are typically indicated separately on a prescription.

C) route of administration.

This option is incorrect because h.s. does not specify how the medication is administered (e.g., orally, intravenously, etc.). The route of administration is a distinct aspect of prescribing that is not addressed by this abbreviation.

D) disease state.

This option is incorrect as h.s. does not relate to any specific disease or condition. Instead, it solely provides guidance on the timing of medication intake.

Conclusion

In summary, the abbreviation h.s. clearly signifies a specific time of day for medication administration, namely bedtime. This distinguishes it from the other options, which pertain to different aspects of prescription writing that h.s. does not address. Therefore, A) time of day is the only correct choice in this context.
