A nurse is preparing to administer valproic acid 400 mg PO bid for migraine headaches. Available is valproic acid 250 mg/5 mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["8"]
To calculate the volume to administer, the nurse should use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL) x 1000
Plugging in the given values, the nurse should get:
Volume (mL) = 400 mg / 250 mg/5 mL x 1000
Volume (mL) = 8 mL
The nurse should round the answer to the nearest whole number and use a leading zero if it applies. Therefore, the nurse should administer 8 mL of valproic acid per dose.

Correct Answer is C
Explanation
Placing the client on his side is an essential action to take during a seizure, as it can prevent airway obstruction and aspiration. The client should be placed on his side, preferably in a lateral recumbent position, to allow saliva and secretions to drain from the mouth.
Holding the client's arms and legs from moving is not appropriate, as it can cause injury, increase agitation, or prolong the seizure. The client should be allowed to move freely during a seizure, but supported and guided away from hazards.
Placing the client back in bed is not necessary, as it can cause harm or delay care. The client should be left on the floor, unless it is unsafe or uncomfortable, and padded with pillows or blankets to protect from injury.
Inserting a tongue blade in the client's mouth is not advisable, as it can cause oral trauma, choking, or damage to the teeth. The client should not have anything inserted into his mouth during a seizure, as he cannot swallow or bite his tongue. The nurse should ensure that the client's airway is clear and patent.
Correct Answer is ["125"]
Explanation
To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, the nurse should get:
Infusion rate (mL/hr) = 250 mL / 2 hr
Infusion rate (mL/hr) = 125 mL/hr
The nurse should round the answer to the nearest whole number and use a leading zero if it applies. Therefore, the nurse should set the IV pump to deliver 125 mL/hr.
