Question: 1 / 400

What solution is exclusively used for arterial lines?

Dextrose

Normal saline

Normal saline is the solution that is exclusively used for arterial lines due to its compatibility with blood and its isotonic nature. This saline solution helps maintain hemodynamic stability and can help prevent blood clots within the arterial line by ensuring adequate fluid balance without causing hemolysis or unwanted cellular reactions.

Other solutions, like dextrose, can lead to complications such as hyperglycemia and cellular hydration issues. Ringer's lactate, while often used for fluid resuscitation, can lead to issues with electrolyte imbalance when utilized in an arterial line context. Water, being hypotonic, can cause hemolysis and is not suitable for this purpose. Therefore, normal saline is the most appropriate choice for ensuring safe and effective functioning of arterial lines.
