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 mL"]
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 D
Explanation
The brachial pulse in the right arm is the best option to assess because it is contralateral to the insertion site and unaffected by the procedure. The radial pulse in the left arm may be diminished or absent due to arterial occlusion or spasm from the catheterization.
Radial pulse in the left arm is wrong because it may be diminished or absent due to arterial occlusion or spasm from the catheterization.
Radial pulse in the right arm is wrong because it may not reflect the true blood pressure or perfusion status of the client because it is ipsilateral to the heart.
Brachial pulse in the left arm is wrong because it may also be compromised by the insertion site and is not a reliable indicator of circulation.
