Final answer:
The volume of blood to be drawn from an ill neonate should be no more than 5% of the circulating volume.
Step-by-step explanation:
The correct answer is b) 5%.
If the neonate is ill, the volume of blood to be drawn should be no more than 5% of the circulating volume. Drawing more than that can lead to further complications and harm the neonate.
For example, if the circulating volume of a neonate is 100 mL, no more than 5 mL of blood should be drawn.
