Which antiseptic is typically used for performing a heel stick on an infant?

Benzalkonium Chloride
Hydrogen Peroxide
Isopropyl Alcohol
Chlorhexidine

The correct answer is: Isopropyl Alcohol

When performing a heel stick on an infant, isopropyl alcohol is commonly used as an antiseptic. This is because isopropyl alcohol is effective in reducing the number of microorganisms on the skin surface immediately prior to the puncture, helping to minimize the risk of infection. Isopropyl alcohol is generally preferred in pediatric settings due to its rapid action and the fact that it evaporates quickly, ensuring that it does not contribute to significant discomfort during the procedure. Additionally, the concentration of isopropyl alcohol commonly used (70% solution) is effective in antimicrobial action while being safe for delicate infant skin. Other antiseptics listed may not be as suitable. Benzalkonium chloride, while used in some antiseptic products, is less effective for skin preparation in blood collection. Hydrogen peroxide can cause skin irritation and is not generally recommended for routine antisepsis in this context. Chlorhexidine is a powerful antiseptic but is typically avoided in neonates due to the potential for absorption and toxicity. Thus, isopropyl alcohol is the most appropriate choice for performing a heel stick on an infant, ensuring effective antisepsis while prioritizing the infant's safety and comfort.
