A nurse is assessing the eyes on a patient and during the inspection the conjunctival sac is red, itchy, and has white thick drainage.
Which finding are these consistent with?

Allergic conjunctivitis.

Viral conjunctivitis.

Bacterial conjunctivitis.

Cataracts.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Allergic conjunctivitis is usually characterized by redness, itching, and watery discharge. It is often associated with allergic reactions to pollen, dust, or pet dander. The discharge in allergic conjunctivitis is typically clear and watery, not white and thick.

Choice B rationale

Viral conjunctivitis is often caused by adenovirus and is characterized by redness, watery discharge, and a gritty sensation in the eye. It is highly contagious and can spread through contact with infected individuals. The discharge in viral conjunctivitis is usually watery, not thick and white.

Choice C rationale

Bacterial conjunctivitis is characterized by redness, itching, and white, thick discharge. It is often caused by bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, or Haemophilus influenzae. The thick discharge is a hallmark of bacterial infection, distinguishing it from allergic or viral conjunctivitis.

Choice D rationale

Cataracts involve the clouding of the eye's natural lens, leading to blurred vision and difficulty seeing at night. They do not cause redness, itching, or discharge from the eye. Cataracts affect the lens inside the eye, not the conjunctival sac.

Correct Answer is D

Explanation

Choice A rationale

The Whisper test evaluates hearing acuity, while the Romberg test assesses balance and proprioception by having the client stand with feet together and eyes closed. Both tests involve sensory assessments but do not directly assess cranial nerve VIII, which is the vestibulocochlear nerve responsible for hearing and balance.

Choice B rationale

PERRLA (pupils equal, round, reactive to light and accommodation) assesses cranial nerves II and III, while EOMs (extraocular movements) assess cranial nerves III, IV, and VI. These tests do not evaluate cranial nerve VIII.

Choice C rationale

Snellen and Rosenbaum tests measure visual acuity for distance and near vision, respectively. These tests assess cranial nerves II and III but do not evaluate cranial nerve VIII.

Choice D rationale

The Rinne and Weber tests are audiometric assessments that specifically evaluate cranial nerve VIII, which controls hearing and balance. The Rinne test compares air and bone conduction of sound, while the Weber test assesses sound lateralization, making them appropriate tests for assessing cranial nerve VIII.

A. Visual acuity. B. Peripheral vision. C. Presence of the red reflex. D. Pupillary constriction to light.

Correct Answer is D

Explanation

Choice A rationale

Visual acuity tests assess the clarity of vision and the ability to discern letters or numbers at a set distance. It is used to test the function of cranial nerve II (optic nerve) rather than cranial nerve III (oculomotor nerve). Testing visual acuity involves using eye charts and assessing each eye separately.

Choice B rationale

Peripheral vision tests evaluate the ability to see objects outside the direct line of vision and are used to test the function of cranial nerve II (optic nerve). Peripheral vision assessment helps in diagnosing conditions like glaucoma but does not test the function of cranial nerve III.

Choice C rationale

The presence of the red reflex is assessed by looking into the eye with an ophthalmoscope to check for abnormalities in the eye's posterior segment. It is not related to the function of cranial nerve III but rather indicates healthy eye structures, including the retina and optic nerve (cranial nerve II).

Choice D rationale

Pupillary constriction to light is a direct test of cranial nerve III function. The oculomotor nerve controls the constriction of the pupil in response to light. By shining a light into the eyes and observing the pupils' response, the nurse can assess the integrity of cranial nerve III.
