A primary healthcare provider prescribes an enteral feeding formula to a client. A nurse finds that the formula's full strength concentration volume is 250 mL.
How much water should the nurse add to the formula to dilute it to half strength?
50 mL
100 mL
250 mL
500 mL
The Correct Answer is C
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.

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 C
Explanation
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.
