Answer to Question 1
C
When a child is critically ill or when long-term IV access is anticipated, a PICC catheter, a Broviac catheter, or an implanted port may be used to access a larger vein. PICCs can be used to infuse IV fluids, parenteral nutrition, blood and blood products, and medications such as antibiotics. Gerontological veins are very fragile, with less subcutaneous support tissue and with thinning of the skin. In older patients, use the smallest gauge possible. For example, a 22-gauge needle is adequate for fluid and medication therapy. PICC lines are not inserted routinely. PICCs are used when long-term IV is needed.
