Final answer:
The maximum safe depth for a heel puncture is 2.4 mm, which is essential to avoid potential complications during the procedure.
Step-by-step explanation:
b) 2.4 mm The maximum depth of a heel puncture that should not be exceeded is 2.4 mm. This limitation is established to minimize the risk of injury and complications such as hitting bone or causing an infection. In the context of healthcare, it is critical to adhere to these guidelines to ensure patient safety during procedures such as blood sampling from infants.The maximum depth of a heel puncture, commonly performed in newborns for blood sampling, is typically regulated to avoid potential complications. The correct answer is:b) 2.4 mm.In neonatal heel puncture procedures, healthcare professionals use a lancet to create a small incision in the heel to collect a blood sample for various tests, such as newborn screening. The depth of the puncture is an essential consideration to ensure that the procedure is effective in obtaining an adequate blood sample while minimizing discomfort and reducing the risk of complications.
The depth of the puncture is generally specified to be around 2.4 mm or less. This depth is designed to reach the capillary bed in the heel, allowing for sufficient blood flow for sampling without causing unnecessary pain or potential damage to deeper structures. It's crucial for healthcare providers to adhere to these guidelines to ensure the safety and well-being of the newborns undergoing such procedures. The specified depth is considered a balance between obtaining an adequate blood sample and minimizing the risks associated with puncturing the delicate tissues in the infant's heel.
