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 B

Explanation

A. Assessment of neurologic status
While neurological assessment is important, it is not the priority in this situation. The immediate priority is managing the chest wound and airway to ensure oxygenation and prevent further complications.

B. Obtain IV access with two large bore lines and blood for lab studies
IV access is important for fluid resuscitation and medication administration but is not the immediate priority compared to securing the airway and ensuring ventilation.

C. Placement of a naso-gastric tube to decompress the stomach
Although the naso-gastric tube may be necessary to decompress the stomach later, it is not the priority in the initial management of a client with a gunshot wound to the chest.

D. Placement of an indwelling catheter (Foley) to measure urine output
While measuring urine output is important for monitoring renal function and fluid balance, it is not the priority in this emergency situation.

A. Atropine 1mg IV push B. Epinephrine 1 mg (1:10,000) IV X1 C. Adenosine 6 mg IV push D. Milrinone 50 mcg/kg IV push

Correct Answer is A

Explanation

A. Atropine 1 mg IV push

A C3 spinal cord injury disrupts sympathetic control, causing bradycardia. Atropine is the first-line treatment for symptomatic bradycardia.

B. Epinephrine 1 mg IV

Epinephrine is used for cardiac arrest, not initial management of bradycardia.

C. Adenosine 6 mg IV push

Adenosine is used for supraventricular tachycardia, not bradycardia.

D. Milrinone 50 mcg/kg IV push

Milrinone is an inotrope used in heart failure, not bradycardia.
