The nurse is deciding on a dosage schedule for methylphenidate (Ritalin). The nurse recognizes that which time is the most appropriate to administer this drug for maximum effectiveness?
Before breakfast or lunch
With meals
After dinner
At bedtime
The Correct Answer is A
A. Before breakfast or lunch
Methylphenidate (Ritalin), a stimulant medication commonly used to treat attention deficit hyperactivity disorder (ADHD), is usually administered before breakfast or lunch for maximum effectiveness. This schedule helps align the peak concentration of the medication with the times when increased focus and attention are often needed, such as during school hours.
B. With meals
While it can be administered with meals, the goal is often to have the medication take effect before meals to help with focus and attention during activities like school or work.
C. After dinner
Administering methylphenidate after dinner may interfere with the patient's ability to fall asleep, as the medication can cause insomnia. It is generally recommended to avoid administering it in the late afternoon or evening.
D. At bedtime
Administering methylphenidate at bedtime is not appropriate due to the potential for insomnia. The stimulant effect of the medication is not aligned with the patient's sleep-wake cycle.

Correct Answer is B
Explanation
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.
Correct Answer is ["125"]
Explanation
`To calculate the rate of infusion in mL/h, you need to divide the total volume of fluid by the total time of infusion.
In this case, you have 1,000 mL of normal saline (NS) to infuse in eight hours.
Therefore, the rate of infusion is 1,000 mL / 8 h = 125 mL/h.
