Correct Answer is ["10"]

Explanation

Step 1: Determine the Medication Concentration

The total amount of medication in the solution is 250 mg.
The total volume of the solution is 5 mL.
To find the concentration per mL:
250 mg ÷ 5 mL = 50 mg/mL

Step 2: Determine the Required Volume

The prescribed dose is 500 mg.
To find the volume needed:
500 mg ÷ 50 mg/mL = 10 mL

Thus, the nurse should administer 10 mL of the solution to deliver the required 500 mg dose.

A. Developing a respiratory infection. B. Taking too much prescribed medication. C. Insufficient sleep. D. Insufficient exercise.

Correct Answer is A

Explanation

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 Crationale:

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

Choice Drationale:

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.
