The nurse is confirming a pediatric dose from an adult dose sent from the pharmacy.
What is an accurate method for calculating the child's dose?
Body surface area (BSA)
Actual body weight
Ideal body weight (BW)
Actual body height
The Correct Answer is B
This is the most commonly used method for calculating pediatric doses, especially for medications that are weight-based. The pediatric dose is typically calculated as a fraction or percentage of the adult dose based on the child's weight. For example, if the adult dose is 100mg and the child weighs 50kg, the child's dose may be calculated as 50mg (50% of the adult dose). Actual body weight takes into account the child's current weight, which can be an important factor in determining the appropriate dose.
Reasons why the other choices are not answers:
A. Body surface area is a method for calculating pediatric doses, but it is typically used for medications that are associated with toxicity or have a narrow therapeutic index.
C. Ideal body weight is an estimate of what a person's weight should be based on their height and gender, rather than their actual weight. It may be used in situations where a child is significantly overweight or underweight, but it is rarely used for pediatric dosing.
D. Actual body height is rarely used for pediatric dosing, as it does not take into account the child's weight or other important factors. It may be used in certain situations, such as when dosing growth hormone therapy.

Correct Answer is B
Explanation
To calculate the dose of dobutamine in mg/hr, we need to convert the patient's weight from pounds (lb) to kilograms (kg) and then use the ordered dose of 10 mcg/kg/min.
1 lb = 0.453592 kg (rounded to 6 decimal places) Patient's weight in kg = 110 lb x 0.453592 kg/lb
Patient's weight in kg = 49.89512 kg (rounded to 5 decimal places)
Now we can calculate the dose of dobutamine in mg/hr using the following formula:
Dose (in mg/hr) = Weight (in kg) x Dose (in mcg/kg/min) x 60 (to convert minutes to hours) / 1000 (to convert mcg to mg)
Dose (in mg/hr) = 49.89512 kg x 10 mcg/kg/min x 60 / 1000
Dose (in mg/hr) = 29.937072 mg/hr (rounded to 3 decimal places)
Therefore, the patient should receive a dose of approximately 29.9 mg/hr of dobutamine.
Correct Answer is C
Explanation
To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..
So the nurse should add 250 mL of water to the formula to dilute it to half strength.
