Which physical change in geriatric patients can complicate blood collection?

The correct answer is that reduced collagen and skin elasticity can complicate blood collection in geriatric patients. As individuals age, their skin undergoes several changes, one of which includes a decrease in collagen production and a reduction in skin elasticity. This can make veins more fragile and make it more difficult for phlebotomists to locate and puncture veins successfully. The skin becomes thinner and less resilient, which can lead to bruising or hematoma formation more easily than in younger patients.

This change is particularly pertinent in geriatric care, as healthcare professionals need to apply modified techniques and extra caution when drawing blood from older patients to minimize discomfort and avoid complications. Understanding these physiological changes is crucial for effective patient care and ensuring a successful blood collection process.
