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 A

Explanation

Choice A reason: Verapamil is a calcium channel blocker used to manage rapid atrial fibrillation. It works by slowing down the conduction of electrical impulses in the heart, helping to control the heart rate.

Choice B reason: Adenosine is used to treat supraventricular tachycardia (SVT) but is not typically used for atrial fibrillation.

Choice C reason: Nitroglycerin is used to relieve chest pain (angina) by dilating the blood vessels but is not used to treat atrial fibrillation.

Choice D reason: Atropine is used to treat bradycardia (slow heart rate) and is not used for atrial fibrillation.

A. Chronic open-angle glaucoma B. Retinal detachment C. Cataracts D. Acute angle-closure glaucoma

Correct Answer is D

Explanation

Choice A reason: Chronic open-angle glaucoma is a gradual condition that usually progresses without noticeable symptoms until significant vision loss has occurred. It is characterized by the gradual buildup of pressure within the eye, but it does not present with sudden, severe symptoms.

Choice B reason: Retinal detachment presents with symptoms such as flashes of light, floaters, and a curtain-like shadow over the field of vision, but it does not typically cause severe pain or pressure in the eyes.

Choice C reason: Cataracts cause blurred vision and decreased visual acuity but develop slowly over time and do not cause sudden severe eye pain or extreme pressure.

Choice D reason: Acute angle-closure glaucoma is characterized by sudden, severe eye pain, blurred and decreased visual acuity, and increased intraocular pressure. This condition is a medical emergency that requires immediate treatment to prevent permanent vision loss.
