A client is ordered Mylanta 1 tablespoon by mouth after meals and at bedtime. How many milliliters should the client take with each dose?
5 mL
10 mL
15 mL
30 mL
The Correct Answer is C
A. 5ML: One tablespoon is equivalent to 15 milliliters, so 5 milliliters is too little for the prescribed dose.
B. 10ML: This amount is also insufficient, as it does not match the standard conversion of one tablespoon to milliliters.
C. 15ML: This is the correct conversion, as one tablespoon is equal to 15 milliliters.
D. 30ML: This amount is double the correct dose, which could lead to overmedication and potential side effects.

Correct Answer is B
Explanation
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 A
Explanation
First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).
Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.
We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..
Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.
