The physician orders acyclovir 400 mg po three times a day for herpes. The medication is supplied in 800-mg tablets. How many tablets will the nurse administer?
The Correct Answer is ["0.5"]
To determine the number of tablets per dose, use the formula:
Tablets per dose = Dose ordered/Dose available
Given:
- Ordered dose = 400 mg
- Available dose = 800 mg per tablet
Tablets per dose = 400mg/(800mg/tablet)
= 0.5 tablet
Thus, the nurse will administer 0.5 tablet per dose.

Correct Answer is B
Explanation
A. Brachial artery. The brachial pulse is commonly used in infants but is not the best choice for assessing circulation in an unconscious adult.
B. Carotid artery. The carotid artery is the preferred site for assessing a pulse in an unconscious adult because it is a central pulse with strong circulation, even in low-perfusion states.
C. Radial artery. The radial pulse is a peripheral pulse and may be difficult to palpate if the patient has poor circulation or cardiac arrest. The carotid pulse is more reliable in emergencies.
D. Apical artery. There is no apical artery; the apical pulse is auscultated over the heart with a stethoscope and is not used in emergency pulse checks.
Correct Answer is ["1.5"]
Explanation
Calculation:
Volume to administer = Dose ordered/ Dose available
Given:
- Ordered dose = 75 mg
- Available concentration = 50 mg/mL
Volume = 75mg/ (50mg/mL)
= 1.5mL
Thus, the nurse will administer 1.5 mL.
