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?
Answer and Explanation

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. Axillary. The axillary method is less accurate because it measures surface temperature, which can be influenced by environmental factors and is typically lower than core temperature.
B. Rectal. The rectal route provides the most accurate core temperature measurement because it closely reflects internal body temperature and is less affected by external conditions. It is commonly used in critically ill patients and infants when precise measurements are needed.
C. Forehead. Forehead (temporal artery) thermometers provide a non-invasive method of measuring temperature but can be less accurate due to external factors like sweating or ambient temperature changes.
D. Oral. Oral temperature is commonly used and provides a good estimate of core temperature, but factors like recent eating, drinking, or mouth breathing can affect accuracy. Rectal temperature remains the most precise method.
