A nurse in the emergency department is assisting with the care of a client who has myasthenia gravis and is in crisis.
The nurse should identify that which of the following factors can cause a myasthenic crisis?.

Developing a respiratory infection.

Taking too much prescribed medication.

Insufficient sleep.

Insufficient exercise.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Developing a respiratory infection can indeed trigger a myasthenic crisis. Any form of stress on the body, including infections, can exacerbate symptoms.

Choice B rationale:

Taking too much prescribed medication is not typically a cause of myasthenic crisis. However, medication changes should always be managed carefully.

Choice C rationale:

Insufficient sleep can contribute to overall stress and fatigue, potentially exacerbating symptoms, but it is not a primary cause of myasthenic crisis.

Choice D rationale:

Insufficient exercise is not a known trigger for myasthenic crisis. While regular exercise can help manage symptoms, lack of exercise is not a direct cause.

Correct Answer is A

Explanation

Choice A rationale:

Antipsychotic medications can cause extrapyramidal symptoms, which include involuntary muscle contractions and tremors.

Choice B rationale:

Insulin, used to treat type 2 diabetes mellitus, does not typically cause extrapyramidal symptoms.

Choice C rationale:

Pancreatic enzymes, used to treat chronic pancreatitis, are not associated with extrapyramidal symptoms.

Choice D rationale:

Beta-adrenergic blockers, used to treat hypertension, do not typically cause extrapyramidal symptoms.

So, the correct answer is A, A client who has schizophrenia and is taking an antipsychotic medication.

A. Chill the medication prior to administration. B. Hold the dropper against the ear canal while instilling the medication. C. Apply gentle pressure with a finger to the tragus of the ear. D. Straighten the external auditory canal by pulling it down and back.

Correct Answer is C

Explanation

The correct answer is choice C. Apply gentle pressure with a finger to the tragus of the ear.

Choice A rationale:

Chilling the medication prior to administration is not recommended. Cold ear drops can cause dizziness or discomfort when instilled into the ear. It is generally advised to warm the drops to body temperature by holding the bottle in your hands for a few minutes before administration.

Choice B rationale:

Holding the dropper against the ear canal while instilling the medication is incorrect. The dropper should be held above the ear canal to avoid contamination and injury. Touching the dropper to the ear canal can introduce bacteria and cause infection.

Choice C rationale:

Applying gentle pressure with a finger to the tragus of the ear helps to facilitate the flow of the medication into the ear canal. This action helps to ensure that the medication reaches the affected area effectively.

Choice D rationale:

Straightening the external auditory canal by pulling it down and back is incorrect for adults. For adults, the correct method is to pull the ear up and back to straighten the ear canal. Pulling it down and back is the method used for children.
