Question

A child who is less than 12 years of age was admitted to the hospital. There was no blood sample taken upon arrival. The child cannot be considered as a donor without using an algorithm if:

a. They have received a transfusion of 2000ml of colloids within the last hour
b. They have received a transfusion of 1000 ml of crystalloids within the last hour
c. They have received an infusion of 1000ml of blood within the last hour
d. All of the above

Answer 1

The child cannot be considered as a blood donor without using an algorithm if they have received any large volume transfusions or infusions within the last hour, including 2000ml of colloids, 1000ml of crystalloids, or 1000ml of blood. The correct answer is d. All of the above.

Step-by-step explanation:

The conditions under which a child who is less than 12 years of age cannot be considered as a donor without using an algorithm are when they have received a transfusion or infusion that might impact their blood volume or composition. Specifically, this includes:

• a transfusion of 2000ml of colloids within the last hour,
• a transfusion of 1000ml of crystalloids within the last hour, and
• an infusion of 1000ml of blood within the last hour.

The correct answer would be d. All of the above, as each of these situations presents a risk to the child's blood volume and could interfere with a donor match due to dilution or alteration of the child's blood components.In order to determine if a child who is less than 12 years of age can be considered as a donor, an algorithm needs to be used. The child cannot be considered as a donor if they have received a transfusion of 2000ml of colloids or 1000 ml of crystalloids or an infusion of 1000ml of blood within the last hour. Therefore, the correct answer is d. All of the above.
