A nurse in the emergency department is caring for a client who is suspected to be in a cholinergic crisis. Which of the following factors should the nurse identify as a possible cause?

High purine diet

High protein diet

Not exercising enough

Taking too much of the prescribed medication

Answer and Explanation

The Correct Answer is D

Choice A reason: A high purine diet is more commonly associated with gout and hyperuricemia, not cholinergic crisis.

Choice B reason: A high protein diet is not directly related to cholinergic crisis. The crisis is related to medication levels rather than dietary factors.

Choice C reason: Not exercising enough is not a direct cause of cholinergic crisis. Physical activity levels do not impact the balance of acetylcholine in the body in this context.

Choice D reason: A cholinergic crisis occurs due to excessive accumulation of acetylcholine, often from taking too much of prescribed anticholinesterase medications. This can lead to overstimulation of the neuromuscular junction and symptoms such as muscle weakness and respiratory distress.

Correct Answer is D

Explanation

Choice A reason: Pyridostigmine is a medication used to treat myasthenia gravis by inhibiting acetylcholinesterase, but it is not used as an antidote for edrophonium overdose. Pyridostigmine helps improve muscle strength by increasing the amount of acetylcholine available at the neuromuscular junction.

Choice B reason: Flumazenil is an antidote for benzodiazepine overdose and has no effect on edrophonium. It works by competitively inhibiting the actions of benzodiazepines on the GABA receptor.

Choice C reason: Acetylcholine itself is not used as an antidote for edrophonium overdose. Administering acetylcholine would not counteract the effects of excessive acetylcholinesterase inhibition caused by edrophonium.

Choice D reason: Atropine is the correct antidote for edrophonium overdose. Atropine is an anticholinergic drug that can counteract the excessive accumulation of acetylcholine caused by edrophonium, thereby alleviating symptoms such as bradycardia and muscle weakness.

A. Mild headaches B. Cloudiness that worsens at night C. Severe eye pain D. Mild eye pain

Correct Answer is C

Explanation

Choice A reason: Mild headaches are not typically associated with increased intraocular pressure. While headaches can accompany eye conditions, they are not as common or specific as severe eye pain in this context.

Choice B reason: Cloudiness that worsens at night could be related to cataracts or other eye conditions but is not a specific manifestation of increased intraocular pressure. Severe eye pain is a more direct indicator of conditions like acute angle-closure glaucoma.

Choice C reason: Severe eye pain is a significant clinical manifestation of increased intraocular pressure, such as in acute angle-closure glaucoma. This condition can lead to sudden, severe eye pain due to the rapid rise in intraocular pressure, which can damage the optic nerve if not treated promptly.

Choice D reason: Mild eye pain may occur in various minor eye conditions but is not as indicative of serious issues like increased intraocular pressure. Severe eye pain is more concerning and requires immediate assessment and intervention.
