Final answer:
Capillary samples can be obtained from alternative sites in the body where capillary blood vessels are present, such as fingertips, earlobes, heels, and foreheads.
Step-by-step explanation:
If the patient does not have arms, capillary samples can be obtained from other locations in the body where capillary blood vessels are present. Some alternative sites for obtaining capillary blood samples include:
- Fingertips or toes
- Earlobe
- Heel
- Forehead
These areas have a rich supply of capillaries and can be easily accessed for blood collection purposes. When collecting a capillary sample from an alternative site, the same principles of capillary action can be utilized by using a small diameter glass tube to draw the blood into.
