The PHCP prescribes 30 mg of phenobarbital by mouth, once daily. The medication label reads phenobarbital 10 mg tablets. The nurse prepares to administer how many tablet(s) per dose?

Explanation:
Dividing the prescribed dose by the tablet strength determines how many tablets are needed. With 30 mg prescribed and each tablet providing 10 mg, you calculate 30 ÷ 10 = 3. So three tablets are required per dose. Since 30 mg is an exact multiple of 10 mg, there’s no need to split tablets.
