which of the following is a characteristic of the troche dosage form?
troches are designed to dissolve quickly on the tongue usually in 60 seconds or less
troches are held in the mouth until dissolved
troches are intended to be chewed before swallowing
troches are coated to prevent them from dissolving in

Explanation:

1. For the first question, "qhs" is an error - prone abbreviation. It can be misinterpreted as "qhr" (every hour) instead of "at bedtime". The other abbreviations "po" (by mouth), "Subcut" (subcutaneous), and "ac" (before meals) are less likely to be misinterpreted in common pharmacy practice.
2. For the second question, troches are solid dosage forms that are held in the mouth until they dissolve. They are not designed to dissolve quickly on the tongue in 60 seconds or less, not intended to be chewed before swallowing, and are not coated to prevent disintegration in the mouth.

Answer:

Question 21: qhs
Question 22: Troches are held in the mouth until dissolved
