Correct Answer is B
Explanation
A. Observing for facial symmetry assesses cranial nerves VII (facial nerve), not cranial nerve III.
B. Cranial nerve III (oculomotor nerve) is responsible for eye movement and pupillary response, making checking the pupillary response to light the correct action.
C. Testing visual acuity primarily assesses cranial nerve II (optic nerve), not cranial nerve III.
D. Eliciting the gag reflex is associated with cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve III.
Correct Answer is D
Explanation
A. Generalized joint discomfort is not commonly associated with contact dermatitis; this condition typically affects the skin locally rather than causing systemic joint symptoms.
B. Systemic symptoms such as elevated temperature are generally not expected with contact dermatitis, as it is usually a localized skin reaction.
C. Pruritus (itching) is a common symptom of contact dermatitis, so denial of pruritus would not be expected.
D. Contact dermatitis often occurs due to exposure to a skin irritant, making a report of such exposure a typical finding in the assessment.
