A nurse is preparing to administer methylphenidate 10 mg PO. Available is methylphenidate oral solution 5 mg/tsp. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["10"]
To administer the correct dose of methylphenidate, which is 10 mg, when the available oral solution concentration is 5 mg per teaspoon, the nurse needs to calculate the volume to administer. One teaspoon is equivalent to 5 milliliters (mL). Since the desired dose is 10 mg, and the available solution has a concentration of 5 mg per teaspoon, the nurse would need two teaspoons to make up the 10 mg dose. Therefore, the nurse should administer 10 mL of the methylphenidate oral solution.

Correct Answer is B
Explanation
A. Give the client two troches in the morning and two troches in the evening. This option misinterprets the frequency of administration; the prescription is for four times a day, not twice.
B. Withhold oral intake until the troche dissolves in the client's mouth. Nystatin troches are designed to dissolve slowly in the mouth, allowing the medication to come into contact with the mucous membranes to treat fungal infections effectively. The client should avoid eating or drinking until the troche has fully dissolved to ensure maximum effectiveness.
C. Tell the client to keep the troche under the tongue for 5 min before swallowing it. Troches should dissolve completely in the mouth, not just be held under the tongue for a specific time.
D. Instruct the client to swallow the troche with 240 mL (8 oz) water. Troches should not be swallowed whole with water; they need to dissolve in the mouth to be effective.
