A client with myasthenia gravis is experiencing a cholinergic crisis. Which symptoms are associated with this condition? (Select all that apply.)

A. Give the child fluids and proceed to the emergency department.
While giving the child fluids is generally important, proceeding to the emergency department without consulting poison control may not be the most appropriate initial action. Poison control can provide specific guidance based on the substance ingested.

B. Call the poison control center and follow directions.
The safest advice for a toddler who has ingested a small amount of household cleaning fluid is to call the poison control center and follow their directions. Poison control centers are staffed with professionals who can provide specific guidance based on the type and amount of the ingested substance. They can advise on the appropriate steps to take, such as whether immediate medical attention is needed or if monitoring at home is sufficient.

C. Administer syrup of ipecac and monitor for vomiting.
The use of syrup of ipecac is no longer recommended as a routine measure for ingested substances. It can have adverse effects and may not be effective for all substances. Consulting poison control for guidance is considered a more appropriate approach.

D. Have the toddler eat bread to absorb the substance.
The ingestion of certain substances may not be effectively addressed by having the toddler eat bread. The specific advice for management should come from poison control, which can provide evidence-based guidance.

To calculate the amount of solution needed for each dose, we need to use the formula:

Amount of solution (mL) = Dose (mg) / Concentration (mg/mL)

Plugging in the given values, we get:

Amount of solution (mL) = 50 mg / 20 mg/mL

Simplifying, we get:

Amount of solution (mL) = 2.5 mL

Therefore, the nurse must administer 2.5 mL of the solution for each dose.
