11. A phlebotomist is preparing to perform venipuncture for blood collection from a 5-year-old patient. Which of the following needles should the phlebotomist use?
Answer: C
The phlebotomist should use a 23-gauge needle for venipuncture in a 5-year-old patient.
A 23-gauge needle is appropriate for pediatric patients, as it is small enough to minimize discomfort while still being effective for blood collection.
A) 16-gauge
A 16-gauge needle is too large for a young child, as it is typically used for larger veins or in emergency situations. Using such a large gauge would likely cause unnecessary pain and trauma for a 5-year-old.
B) 18-gauge
While an 18-gauge needle is smaller than a 16-gauge, it is still not ideal for a pediatric patient. It may cause significant discomfort and is generally reserved for adults or larger veins, making it unsuitable for a 5-year-old.
C) 23-gauge
The 23-gauge needle is specifically designed for pediatric venipuncture, as it strikes a balance between size and comfort. It is small enough to reduce pain and is effective for blood collection in younger patients, making it the best choice.
D) 27-gauge
A 27-gauge needle is too small for effective venipuncture in most cases, as it may not allow for adequate blood flow. While it may cause less pain, it is not suitable for blood collection in a child, as it could lead to difficulties in obtaining an adequate sample.
Conclusion
The 23-gauge needle is the most appropriate choice for venipuncture in a 5-year-old, as it effectively balances comfort and functionality. Options A, B, and D either pose risks of discomfort or inadequate blood flow, underscoring why the 23-gauge needle is the best option in this context.
