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
Performing neurovascular checks with vital signs is an important action to take following a cardiac catheterization accessed through the femoral artery, as it can help monitor for complications such as bleeding, hematoma, infection, thrombosis, or embolism. The nurse should assess the color, temperature, sensation, movement, and pulses of the affected leg, as well as the blood pressure, heart rate, and oxygen saturation of the client.
Instructing the client to perform range-of-motion exercises to his lower extremities is not appropriate, as it can increase the risk of bleeding or dislodging the arterial sheath or closure device. The client should keep the affected leg straight and avoid bending or lifting it for several hours after the procedure, or as directed by the provider.
Restricting the client's fluid intake is not necessary, as fluid intake can help prevent dehydration and contrast- induced nephropathy following a cardiac catheterization. The client should be encouraged to drink fluids, unless contraindicated.
dAmbulating the client 1 hr following the procedure is not advisable, as it can cause bleeding, hematoma, or vascular injury. The client should remain on bed rest for 2 to 6 hours after the procedure, or as directed by the provider, and resume ambulation gradually and with assistance.
Correct Answer is A
Explanation
a.This is appropriate as regular, moderate exercise can help improve cardiovascular health and functional capacity in clients with heart failure. It is essential to discuss appropriate types and levels of exercise based on the individual’s condition.
b.This is incorrect because clients should be instructed to notify the provider if they gain 1 kg (2.2 lbs) in one day or 2 kg (4.4 lbs) in one week. A weight gain of 0.5 kg is not typically a threshold for concern.
c. Take diuretics early in the morning and before bedtime is wrong because it may disrupt the client's sleep patern and cause nocturia. The nurse should advise the client to take diuretics early in the morning and avoid taking them in the evening or at night, unless prescribed otherwise.
d. Take naproxen for generalized discomfort is wrong because naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can worsen heart failure by causing sodium and water retention, increasing blood pressure, and reducing the effectiveness of diuretics and other heart failure medications. The nurse should advise the client to avoid NSAIDs and use acetaminophen or other alternatives for pain relief, as prescribed by the provider.
