Final answer:
For adults, capillary blood samples are typically collected from the fingertip, while for neonates, the heel is the recommended site. This approach allows for safe and efficient capillary blood collection using a small glass tube.
Step-by-step explanation:
Capillary blood samples are commonly collected from different sites on the body, depending on whether the patient is an adult or a neonate. For adults, the preferred site for capillary blood sampling is the fingertip. The skin on the fingertip is thin enough to easily puncture for blood collection, yet thick enough to prevent easy bruising or excessive bleeding. In contrast, for neonates, the recommended site is the heel. The heel provides a sufficient area for a safe puncture and avoids interference with bone, which could lead to complications such as osteomyelitis.
The correct answer to the question "Where is Capillary blood samples taken for adults and neonates?" is a. Adults: Fingertip; Neonates: Heel. This method of blood collection uses capillary action to draw blood into a small diameter glass tube, minimizing discomfort and allowing for a quick collection of a small blood sample for medical analysis.
