Question

A phlebotomist is taking blood from a 3 year old child who weighs 15.9 kg (35 lbs), what blood collection amount is within total volume guidelines for a 1 month period for this patient?

Answer 1

To calculate the safe blood collection volume for a 3-year-old child weighing 15.9 kg, multiply their body weight by 7 ml/kg, resulting in a total of 111.3 ml for a one month period.

Step-by-step explanation:

When considering the blood collection amount guidelines for pediatric patients, it is important to base the calculations on the child's weight and the general recommendations for blood volume in children. The amount of blood in the human body is about 8 percent of the body weight. In adults, males have around 5 to 6 liters of blood, and females average 4-5 liters.

For the specific case of a 3-year-old child weighing 15.9 kg (35 lbs), we can estimate the total blood volume using the percentage mentioned. As the risk guidelines suggest, no more than 7 ml of blood per kilogram of body weight should be taken over a period to avoid significant blood volume loss. Therefore, the maximum safe blood collection volume over one month would be:

15.9 kg x 7 ml/kg = 111.3 ml

This volume is appropriate to maintain safety while allowing for necessary diagnostic procedures.
