Final answer:
The best nursing intervention for a 4-year-old child needing a bandage at a blood draw site is to apply a small bandage. This approach is not only compassionate but also prevents potential infection and supports the body's natural healing processes after a puncture wound.
Step-by-step explanation:
Best Nursing Intervention for Applying a Bandage
In the scenario presented, the best nursing intervention would be applying a small bandage to the site where the blood sample was drawn from the 4-year-old child. This is a caring and responsive action that acknowledges the child's request and ensures their comfort. It not only addresses the immediate physical need to cover the puncture site but also provides emotional support, which is particularly important for a young child in a healthcare setting. While asking why the child needs a bandage could provide insight, it may delay the comforting action. Similarly, explaining why the blood sample is taken or telling the child that the bleeding will stop may be informative but do not directly address the child's expressed need.
Applying a bandage also has practical benefits. It helps to protect the site from infection and supports the body's wound-healing response, which includes the formation of a blood clot followed by other healing processes. An uncovered puncture site can be a point of entry for bacteria, potentially leading to increased redness, swelling, and pain, which are signs of infection. Furthermore, after a patient has a blood draw, they should be monitored for these signs as part of post-procedural care.
In the case of a blood draw for type testing, it is normal for a patient's blood to agglutinate with both anti-A and anti-B antibodies if they have an AB blood type. This is a routine part of blood typing, as a visible agglutination response helps technicians determine a patient's blood type.
