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 B
Explanation
The priority nursing action is to notify the provider of the client's allergy because shellfish allergy may indicate an allergy to iodine, which is commonly used as a contrast dye in cardiac catheterization. This could cause a severe allergic reaction or anaphylaxis during the procedure, which could be life-threatening. The provider may need to order a different type of contrast dye or premedicate the client with antihistamines or steroids to prevent an allergic reaction.
a. Ask the client if any other foods cause such a reaction is wrong because it is not the priority action and it does not address the potential risk of iodine allergy.
c. Notify the dietary department of the client's allergy is wrong because it is not relevant to the cardiac catheterization and it does not prevent an allergic reaction during the procedure.
d. Atach a wrist band indicating the client's allergy is wrong because it is not sufficient to alert the provider or the catheterization team of the client's allergy and it does not prevent an allergic reaction during the procedure.
Correct Answer is B
Explanation
Edema is a common finding in clients who have chronic venous insufficiency, due to the impaired venous return and increased capillary pressure. The edema is usually worse at the end of the day and improves with elevation.
a. Thick, deformed toenails are more likely to be seen in clients who have fungal infections or peripheral arterial disease, not chronic venous insufficiency.
c. Dependent rubor is a sign of peripheral arterial disease, not chronic venous insufficiency. It is a reddish color of the lower extremities that occurs when they are lowered and disappears when they are elevated.
d. Hair loss is another sign of peripheral arterial disease, not chronic venous insufficiency. It is caused by the reduced blood supply to the hair follicles.
