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.

Step 1 is to determine the amount of lorazepam needed, which is 2 mg as prescribed.

Step 2 is to calculate the number of tablets required. Since each tablet contains 1 mg, we divide the prescribed dose by the strength per tablet:
