A nurse is assessing a client's cranial nerves as part of a neurological examination. Which action should the nurse take to assess cranial nerve II?

A.

Assess visual acuity

B.

Elicit gag reflex

C.

Checking for pupillary response to light

D.

Observing for facial symmetry

Answer and Explanation

The Correct Answer is A

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 ["A","C","D"]

Explanation

A. Decreased urine output: While not a direct sign of pneumonia, decreased urine output can be an objective finding indicative of dehydration, which often accompanies infections like pneumonia.

B. Headache: Although the client has a headache, it is a subjective symptom rather than an objective finding and is not a primary indicator of pneumonia.

C. Respiratory assessment: The respiratory assessment reveals shortness of breath, crackles in the right lower lobe, and tachypnea, which are commonly associated with pneumonia.

D. Chest X-ray: The chest X-ray shows areas of increased density and infiltrates in the right lower lobe, a hallmark finding that indicates pneumonia.

E. Religion: This does not relate to the clinical findings associated with pneumonia.

F. Bowel sounds: Normal bowel sounds are not indicative of pneumonia.

G. Perception of needles: This is irrelevant to the diagnosis of pneumonia.

Correct Answer is A

Explanation

A. This is the correct answer as conjunctivitis, commonly known as pink eye, is characterized by redness, swelling, and discharge from the eye, which is likely what the image shows.

B. Cataracts typically present as clouding of the lens of the eye, leading to blurred vision but do not present with redness or discharge like conjunctivitis.

C. This condition often involves increased intraocular pressure and can lead to vision loss, but it does not usually cause the symptoms depicted in the image of conjunctivitis.

D. This is primarily associated with central vision loss and does not produce the external symptoms of redness or discharge typical of conjunctivitis.
