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 D

Explanation

Choice A rationale:

Blood backing up in the IV tubing indicates a problem with the IV line, not necessarily infiltration.

Choice B rationale:

A long red streak up the arm could indicate phlebitis, not infiltration.

Choice C rationale:

Loose tape could cause the IV needle to dislodge, but it doesn’t directly indicate infiltration.

Choice D rationale:

Swelling around the IV site is a common sign of infiltration.

So, the correct answer is D. “My baby’s fingers are looking swollen.”.

A. Withhold dose if having a fine hand tremor. B. Avoid foods with a high tyramine content. C. Limit daily fluid intake. D. Follow a low-sodium diet.

Correct Answer is A

Explanation

Choice A rationale:

Withholding the dose if having a fine hand tremor is not recommended. Hand tremors are a common side effect of lithium, but they can be managed by adjusting the dose.

Choice B rationale:

Avoiding foods with a high tyramine content is not necessary for lithium users. This dietary restriction is typically associated with certain antidepressants, not lithium.

Choice C rationale:

Limiting daily fluid intake is incorrect. Lithium can cause increased thirst and urination, so it’s important to maintain adequate hydration.

Choice D rationale:

Following a low-sodium diet is not advised. Both salt and fluid can affect the levels of lithium in your blood, so it’s important to consume a steady amount every day.

So, the correct answer is, none of the above.
