Due to cranial nerve involvement in Bell's palsy, which of the following would prevent a potential complication from the disorder?

Wearing sunglasses while symptomatic

Applying an eye patch before sleep

An antihistamine eye drop

Antibiotic ophthalmic ointment

Answer and Explanation

The Correct Answer is B

A. Wearing sunglasses while symptomatic

Sunglasses reduce photophobia, but they do not prevent corneal damage from dryness.

B. Applying an eye patch before sleep

Bell's palsy affects cranial nerve VII (facial nerve), leading to incomplete eye closure. This can cause corneal abrasions and dryness. An eye patch at night prevents corneal injury.

C. An antihistamine eye drop

Antihistamine eye drops may dry out the eye further, worsening the risk of corneal injury.

D. Antibiotic ophthalmic ointment

Antibiotics are not necessary unless an infection is present. Lubricating drops or artificial tears are more appropriate.

Correct Answer is ["A","B","C","D"]

Explanation

A. Causative agent and duration of exposure – Chemical, electrical, or thermal burns differ in severity.

B. Depth of burn – Superficial, partial-thickness, and full-thickness burns determine severity.

C. Anatomical location – Burns over joints, face, or perineum have higher morbidity.

D. Total Body Surface Area (TBSA) percentage – Used to estimate fluid resuscitation needs (e.g., Parkland formula).

E. Time of day burn occurred – Time does not affect burn severity.

A. Follows an object with eyes without nystagmus or strabismus B. Moves the tongue out midline without tremors or deviation C. Moves the head and shoulders against resistance with equal strength D. Demonstrates full range of the neck

Correct Answer is C

Explanation

A. Follows an object with eyes without nystagmus or strabismus
Cranial nerves III (oculomotor), IV (trochlear), and VI (abducens) control eye movement. CN XI does not control eye movement.

B. Moves the tongue out midline without tremors or deviation
Cranial nerve XII (hypoglossal nerve) controls tongue movement.

C. Moves the head and shoulders against resistance with equal strength
Cranial nerve XI (spinal accessory nerve) controls the sternocleidomastoid and trapezius muscles. If intact, the client can shrug shoulders and turn the head against resistance with equal strength.

D. Demonstrates full range of the neck
Full range of motion in the neck involves multiple muscles, not just those innervated by CN XI.
