A client is to receive Valproic Acid 400 mg every 12 hours by mouth. What is the total dosage in milligrams the client should receive in a 24-hour period? (Use a preceding zero if it applies. Do not use trailing, zeros. Round to the nearest whole number)

Determine the number of doses in 24 hours: Since the medication is given every 12 hours, there will be two doses in a 24-hour period (24 hours / 12 hours/dose = 2 doses). Calculate the total dosage: Each dose is 400 mg. Total dosage = 2 doses x 400 mg/dose = 800 mg
