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.
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 ["0.5 mL."]
Explanation
Step 1 is to determine the amount of lorazepam in milligrams that the nurse needs to administer, which is 1 mg. Step 2 is to calculate the volume of lorazepam oral solution needed to deliver this dose. This is done by dividing the required dose by the concentration of the solution. So, (1 mg ÷ 2 mg/mL) = 0.5 mL.
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.”.
