After keratoplasty, you observe that the patient's cornea is cloudy. What should you do?

Report signs of corneal rejection to the physician.

Elevate the patient's head and encourage increased fluid intake.

Reassure the patient that cloudiness is normal for several weeks after surgery.

Prepare the patient for emergency surgery.

Answer and Explanation

The Correct Answer is A

a) Report signs of corneal rejection to the physician: Cloudiness may indicate graft rejection, requiring immediate medical attention.
b) Elevate the patient's head and encourage increased fluid intake: This can help reduce intraocular pressure but does not address corneal rejection.
c) Reassure the patient that cloudiness is normal for several weeks: Persistent cloudiness is not typical and warrants evaluation.
d) Prepare the patient for emergency surgery: Emergency surgery is not the first step unless complications are severe.

Correct Answer is C

Explanation

a) Has no serious complications: Bacterial pharyngitis, especially streptococcal pharyngitis, can have serious complications, such as rheumatic fever or glomerulonephritis, which are not seen with viral pharyngitis.
b) Presents a negative culture: Bacterial pharyngitis typically presents with a positive throat culture for bacteria, while viral pharyngitis typically shows a negative culture.
c) Has an abrupt onset: Bacterial pharyngitis often has a sudden and severe onset of symptoms, while viral pharyngitis tends to have a more gradual onset.
d) Presents a normal complete blood count (CBC): In bacterial pharyngitis, the CBC may show an elevated white blood cell count, while in viral pharyngitis, the CBC may remain normal or slightly elevated.

A. Assess the 6 cardinal gazes B. Ask the client to her clench teeth. C. Anticipate the use of a tonometer D. Use a Snellen chart.

Correct Answer is D

Explanation

a) Assess the 6 cardinal gazes: This test assesses cranial nerve III, IV, and VI (oculomotor, trochlear, and abducens), which control eye movement, not the optic nerve.
b) Ask the client to clench teeth: This tests cranial nerve V (trigeminal nerve), which controls sensation in the face and motor functions like chewing.
c) Anticipate the use of a tonometer: A tonometer measures intraocular pressure (IOP), which is related to glaucoma, but it does not specifically assess cranial nerve II.
d) Use a Snellen chart: The Snellen chart is used to test visual acuity, which evaluates the function of cranial nerve II (optic nerve).
