Final answer:
Sites to avoid for a finger stick include the fingertip pads due to higher density of touch receptors, leading to increased pain. Other factors such as infections and repeated needle use in drug addicts also influence site selection.
Step-by-step explanation:
When selecting a location for a finger stick to test glucose levels or for other blood sampling needs, certain sites should be avoided due to higher risks of infections or discomfort. It is recommended to avoid using the fingertips' pads and instead use the sides of the fingers.
Using the pads of the fingers can stimulate the touch receptors, which are more densely located there, leading to increased pain and discomfort.
This practice applies to individuals who frequently need blood sampling, including diabetic patients, drug addicts who may have compromised sites due to repeated needle use, and healthcare professionals like phlebotomists and dentists who perform procedures involving needle sticks.
When selecting a location for a finger stick, it is important to avoid sites that may increase the risk of infection or needle sticks.
Some sites to avoid include locations frequented by drug addicts or individuals at higher risk of infections, such as phlebotomists. Dentists are also at risk and should take precautions.
