A nurse is preparing to administer valproic acid 400 mg PO bid for migraine headaches. Available is valproic acid 250 mg/5mL. 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.)

Answer and Explanation

The Correct Answer is ["8"]

Volume (mL) = Desired dose (mg) / Concentration (mg/mL)

In this case:

Desired dose = 400 mg
Concentration = 250 mg/5 mL = 50 mg/mL

Plugging the values into the formula:

Volume = 400 mg / 50 mg/mL = 8 mL

Correct Answer is A

Explanation

Rationale:

A. Cranial nerve VII (facial nerve) is not primarily responsible for hearing; however, it does have some sensory function in the ear region. The primary cranial nerve responsible for hearing is cranial nerve VIII (vestibulocochlear), which is not listed among the options.

B. Cranial nerve X (vagus nerve) is primarily involved in autonomic functions and does not directly relate to hearing.

C. Cranial nerve I (olfactory nerve) is responsible for the sense of smell.

D. Cranial nerve II (optic nerve) is responsible for vision.

A. PICC line insertion site B. Breath sounds C. Temperature D. Heart rate

Correct Answer is ["A","C","D"]

Explanation

A. PICC line insertion site: The client reports pain, redness, and edema at the PICC line insertion site, which are signs of a possible infection. This finding requires immediate follow-up to prevent complications like bloodstream infection or sepsis.

B. Breath sounds: The client’s breath sounds are clear and unchanged from Day 1, so this finding does not require immediate follow-up.

C. Temperature: The client's temperature has risen to 39 °C (102.2 °F) from 37.2 °C (99 °F) on Day 1. Such a significant increase in temperature indicates a possible infection and needs prompt intervention.

D. Heart rate: The client’s heart rate has increased to 108/min from 66/min, suggesting tachycardia. This could be a response to infection, potentially linked to sepsis, and warrants immediate follow-up.

E. Albumin level: The albumin level has increased to within the normal range, which is a positive trend and does not require urgent intervention.
