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

A.

Wearing sunglasses while symptomatic

B.

Applying an eye patch before sleep

C.

An antihistamine eye drop

D.

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 B

Explanation

A. Vocalization, strength, and pupillary response and accommodation are not components of GCS. Strength testing is part of a motor exam, and pupillary response is part of a cranial nerve assessment.

B. Eye opening, verbal response, and motor response are the three components of the Glasgow Coma Scale (GCS), which assesses a client’s neurological status and level of consciousness.

C. Pupillary reaction, eye opening, and motor response is incorrect because pupillary reaction is not a component of the GCS.

D. Motor response, sensory response, and level of consciousness is incorrect because sensory response is not a part of the GCS.

Correct Answer is C

Explanation

A. Diphenhydramine 50 mg PO
Diphenhydramine (Benadryl) treats mild allergic reactions but is not sufficient for anaphylaxis. The presence of SOB and angioedema suggests airway compromise, requiring epinephrine.

B. Famotidine 40 mg PO
Famotidine (H2 blocker) can help with allergic reactions but is not the priority in an emergency.

C. Epinephrine 1 mg IM
Epinephrine is the first-line treatment for anaphylaxis. It reverses airway swelling, hypotension, and bronchoconstriction. The standard IM dose is 0.3-0.5 mg, not 1 mg, but epinephrine remains the priority drug.

D. A fluid bolus of normal saline
IV fluids help treat hypotension in anaphylaxis, but epinephrine is the priority intervention.
