Question

"Patient: 48-year-old woman

Chief complaint: I can't really see well out of my right eye. My eyelids have been dropping since I woke up this morning.
Background/Patient history: Patient got Botox (botulism toxin) injections in her forehead one day prior.

How can you explain the relationship between the patient's prior treatment and her current complaint
a. The injections injured the trigeminal nerve, permanently paralyzing the affected muscle
b. The injections pierced blood vessels, preventing blood flow to the muscles of the eyelid.
c. the toxin lowered the threshold for depolarization of the sarcolemma of the paralyzed muscle fiber
d. The toxin inhibited the release of acetylcholine from neuron
e. The toxin blocked parasympathetic innervation to the structures of the forehead and surrounding areas."

Answer 1

Botox injections can cause muscle paralysis, which explains the patient's complaint of not being able to see well out of her right eye and drooping eyelids.

Step-by-step explanation:

The patient's current complaint of not being able to see well out of her right eye and drooping eyelids can be explained by the prior treatment of Botox injections in her forehead. Botox, which is a botulism toxin, works by inhibiting the release of acetylcholine from neurons. Acetylcholine is a neurotransmitter that plays a key role in muscle contraction. When the release of acetylcholine is blocked, it leads to muscle paralysis.
