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
Obtaining a pair of slipper socks for the client is a simple and safe way to provide warmth and insulation to the feet, which can improve blood flow and comfort.
Placing a moist heating pad under the client's feet is not recommended, as it can cause burns, vasodilation, or increased fluid loss, which can worsen the condition.
Increasing the client's oral fluid intake is not relevant, as it does not affect the temperature or circulation of the feet.
Rubbing the client's feet briskly for several minutes is not advisable, as it can cause trauma, inflammation, or ulceration to the fragile skin and tissues of the feet.

Correct Answer is B
Explanation
The correct answer is B
Choice B reason: Intermittent claudication
Intermittent claudication is a characteristic symptom of PAD in the early stage, due to the reduced blood flow to the muscles during exercise. It is a cramping pain in the legs that occurs with walking and is relieved by rest.
Choice A reason: Dependent rubor is a sign of PAD in the advanced stage, due to the impaired vasodilation and reactive hyperemia. It is a reddish color of the lower extremities that occurs when they are lowered and disappears when they are elevated.
Choice C reason: Foot ulcers are a complication of PAD in the late stage, due to the poor wound healing and tissue necrosis. They are usually located on the toes, heels, or pressure points.
Choice D reason: Rest pain is another sign of PAD in the late stage, due to the severe ischemia and nerve damage. It is a persistent pain in the feet or toes that occurs at night and is not relieved by rest.
