A health care provider prescribes 50 mg of a drug. The drug is only available in a 20 mL vial that contains 20 mg/mL of the drug. How much solution must the nurse administer for each dose?
The Correct Answer is ["2.5"]
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.

Correct Answer is D
Explanation
A. High-sodium foods: Sodium intake is not specifically contraindicated with methylphenidate (Ritalin). However, maintaining a balanced and healthy diet is generally recommended for overall well-being.
B. High-sugar foods and drinks: While there is no strict contraindication with methylphenidate and sugar, a diet high in sugar may contribute to hyperactivity and may not be conducive to managing symptoms of ADHD. It's advisable to promote a balanced diet with reduced sugar intake.
C. High-fat foods: There is no direct contraindication between methylphenidate and high-fat foods. However, maintaining a balanced diet with a moderate intake of fats is generally recommended for overall health.
D. Caffeinated foods and drinks: This is the correct answer. Methylphenidate is a stimulant, and combining it with additional sources of caffeine can lead to an increase in stimulant effects, potentially causing adverse reactions.
Correct Answer is ["40"]
Explanation
To calculate the dosage of docusate sodium (Colace) for a 10-year-old child, we need to divide the total amount of medication by the number of doses. The total amount of medication is 120 mg/day, and the number of doses is 3. Therefore, we can use the following formula:
Dosage per dose = Total amount / Number of doses
Dosage per dose = 120 mg / 3
Dosage per dose = 40 mg
The child will receive 40 mg of docusate sodium (Colace) per dose, three times a day.
