Regarding precautions for finger puncture, what is a true statement?

Performing finger punctures involves specific considerations to ensure patient safety and the accuracy of test results. The correct statement indicates that finger punctures should be avoided on infants under 1 year of age. This is primarily due to the small size and delicate nature of an infant's fingers, which can make it more difficult to obtain an adequate blood sample without causing excessive trauma or discomfort.

In addition, the anatomical and physiological characteristics of infants, such as their small blood volume and thinner skin, require that alternative sites or methods are considered to minimize any potential complications or risk of injury. This precaution reflects best practices in pediatric care, ensuring that blood collection methods are suitable for the patient's age and size.

Other options do not accurately represent established guidelines and may lead to unnecessary risk or complications. Punctures being exclusively for infants, restrictions based solely on age without consideration for other factors, or limitations to one hand do not reflect the evidence-based practices essential in phlebotomy.
