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?

Answer and Explanation

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.

A. Bradycardia B. Fluid retention C. Nervousness and tremors D. Respiratory depression

Correct Answer is D

Explanation

A. Bradycardia

Bradycardia is not a common side effect of diphenoxylate with atropine. Atropine, which is included in the combination, has anticholinergic effects that can lead to an increased heart rate (tachycardia), not bradycardia.

B. Fluid retention

Fluid retention is not a common side effect of diphenoxylate with atropine. In fact, the medication is used to treat severe diarrhea, and the goal is to decrease fluid loss associated with diarrhea rather than causing fluid retention.

C. Nervousness and tremors

Nervousness and tremors are not common side effects of diphenoxylate with atropine. Atropine's anticholinergic effects may cause nervousness, but these effects are generally not prominent at therapeutic doses.

D. Respiratory depression

This is the correct choice. Respiratory depression is a potential side effect of diphenoxylate with atropine, particularly if the medication is misused or taken in excessive amounts. Atropine is included in the combination to discourage misuse, as it can cause unpleasant anticholinergic effects.
