Correct Answer is A

Explanation

A. Assessing visual acuity directly tests cranial nerve II (the optic nerve), which is responsible for vision.

B. Eliciting the gag reflex tests cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve II.

C. Checking for pupillary response to light primarily assesses the function of cranial nerve II but is more associated with cranial nerve III (oculomotor) since it involves the constriction of the pupil. While relevant, it is not the best standalone action for assessing cranial nerve II specifically.

D. Observing for facial symmetry is associated with cranial nerve VII (facial nerve), not cranial nerve II.

Correct Answer is ["8"]

Explanation

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
