A child who weighs 55 pounds receives a prescription for isoniazid 10 mg/kg/day by mouth (PO) once a day.

The bottle is labeled, “Isoniazid Oral Solution, USP 50 mg per 5 mL.”. How many mL should the nurse administer? . .
Answer and Explanation

The Correct Answer is ["25"]

Answer and explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).

Step 2 is to calculate the total daily dosage. The prescription is for isoniazid 10 mg/kg/day. So, the total daily dosage in mg is 10 mg/kg/day × 25 kg = 250 mg/day.

Step 3 is to calculate the volume of the oral solution to administer. The bottle is labeled, “Isoniazid Oral Solution, USP 50 mg per 5 mL.”. So, the volume in mL to administer is (250 mg/day ÷ 50 mg) × 5 mL = 25 mL. Therefore, the nurse should administer 25 mL of the Isoniazid Oral Solution, USP 50 mg per 5 mL, once a day.

Step 3: A 1,000 mL bag of lactated Ringer’s solution containing 10 units of oxytocin is infusing via an 18-gauge peripheral IV in the left forearm at 125 mL per hour, with 500 mL remaining in the bag.

Correct Answer is B

Explanation

Choice A rationale
Nonstimulant medications can be beneficial in the treatment of ADHD. They are often used when stimulant medications are not effective or cause bothersome side effects.
Choice B rationale
Designating an established area for study is a beneficial strategy for children with ADHD. It helps to create a structured environment which can aid in focusing and completing tasks.
Choice C rationale
Being diagnosed with ADHD does not automatically qualify a child for a specialized education plan. Each child’s needs are evaluated individually, and while some may benefit from a specialized plan, it is not a universal requirement.
Choice D rationale
While creating an organization chart for tasks can be helpful for some children with ADHD, understanding this strategy does not necessarily demonstrate an understanding of the overall treatment for ADHD45.
