Answer to Question 1

C

Feedback
A The optic nerve is tested by using the Snellen chart or asking the patient to read printed material.
B The facial nerve is tested by having the patient smile, frown, puff out cheeks, and raise and lower eyebrows while the nurse looks for asymmetry. Having the patient identify salty or sweet tastes on the front of the tongue also tests the facial nerve.
C The trigeminal nerve is tested by lightly touching the cornea with a wisp of cotton, by assessing the corneal reflex, and by measuring sensation of light pain and touch across the skin of the face.
D The oculomotor nerve is tested by assessing directions of gaze, and testing papillary reaction to light and accommodation.

Answer to Question 2

A

Feedback
A Tube placement must be verified by radiography before enteral feedings.
B Auscultating the abdomen is not appropriate.
C Measuring the pH of aspirated fluid is appropriate for ensuring ongoing placement at the bedside but is not done for initial verification of placement.
D Administering a bolus into a nasoenteric tube to verify initial placement is not appropriate.
