A client is admitted to the hospital with a myasthenic crisis. The nurse should anticipate which potential precipitating factors for this event?
The client consumes a high purine diet
Taking too much of their medication
Taking too little of the prescribed medication
Taking their medication while on an empty stomach
The Correct Answer is C
Choice A reason: Consuming a high purine diet is not related to myasthenic crisis. High purine diets are more commonly associated with conditions like gout, where uric acid levels become elevated.
Choice B reason: Taking too much of their medication can lead to a cholinergic crisis, not a myasthenic crisis. A cholinergic crisis occurs due to excessive accumulation of acetylcholine, often from overmedication with anticholinesterase drugs.
Choice C reason: Taking too little of the prescribed medication is the primary precipitating factor for a myasthenic crisis. Inadequate levels of medication lead to insufficient acetylcholine at neuromuscular junctions, causing severe muscle weakness and potentially life-threatening respiratory failure. This situation requires immediate medical intervention to stabilize the patient.
Choice D reason: Taking medication on an empty stomach may affect absorption rates, but it is not a direct precipitating factor for a myasthenic crisis. The crisis is more closely linked to under-medication or missed doses of anticholinesterase drugs.

Correct Answer is D
Explanation
Choice A reason: Increased temperature is a common symptom of many infections, including otitis media, but it does not specifically indicate a tympanic membrane rupture. Fever may accompany the infection but is not a definitive sign of membrane rupture.
Choice B reason: Sudden pain relief can be an indicator of a tympanic membrane rupture in otitis media. This occurs because the pressure built up in the middle ear is suddenly released when the membrane ruptures. However, it is not the only definitive sign.
Choice C reason: A popping sensation when swallowing is a symptom associated with eustachian tube dysfunction rather than a tympanic membrane rupture. It indicates that there is a change in the pressure within the middle ear but not necessarily a rupture.
Choice D reason: Green-blue discharge in the ear canal is a classic sign of a tympanic membrane rupture. This discharge is usually pus mixed with blood from the middle ear and indicates that the membrane has ruptured, allowing the fluid to drain out. This finding is definitive and requires medical attention.
Correct Answer is A
Explanation
Choice A reason: Atropine is an anticholinergic medication that blocks the effects of the parasympathetic nervous system. One of its effects is relaxation of the smooth muscles in the bladder, which can lead to urinary retention. This occurs because the bladder's ability to contract is inhibited, making it difficult for the patient to void.
Choice B reason: Bradycardia is not an expected effect of atropine. In fact, atropine is often used to treat bradycardia by increasing heart rate. It works by blocking the vagus nerve's influence on the heart, which normally acts to slow the heart rate. Therefore, atropine would be expected to cause an increase in heart rate, not a decrease.
Choice C reason: Diarrhea is not a common effect of atropine. Atropine works by reducing the activity of the gastrointestinal tract, leading to a decrease in bowel movements and potentially causing constipation rather than diarrhea. Anticholinergic drugs like atropine reduce gastrointestinal motility, which can lead to a slower passage of food through the intestines.
Choice D reason: Vomiting is not typically associated with the administration of atropine. While nausea and vomiting can be side effects of many medications, atropine more commonly causes dry mouth, blurred vision, and constipation. The medication's action on the gastrointestinal tract tends to slow digestive processes rather than stimulate vomiting.
