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 ["3"]

Explanation

Step 1: Identify Given Information

Prescribed dose: 7.5 mg
Available tablet strength: 2.5 mg per tablet

Step 2: Calculate the Number of Tablets

To determine how many tablets to administer, divide the prescribed dose by the strength of each tablet:

7.5 mg ÷ 2.5 mg/tablet = 3 tablets

The nurse should administer 3 tablets of olanzapine.

Correct Answer is ["15"]

Explanation

Step 1 is to determine the amount of amantadine needed, which is 150 mg as prescribed.

Step 2 is to calculate the volume of the solution needed to deliver this dose. The available solution has a concentration of 50 mg per 5 mL. Using the formula:

(Prescribed dose ÷ Available dose) × Volume per dose

(150mg ÷ 50mg) × 5mL = 15mL

Therefore, the correct answer is 15 mL.
