What is the total volume for diluting medication given via ET tube?

The correct answer reflects the standard protocol for diluting medications administered via an endotracheal (ET) tube. In this context, a volume of 10 ml of normal saline (NS) is typically used for dilution. This amount is considered adequate for ensuring that the medication is properly absorbed and effectively delivered into the lungs when administered through the ET tube.

Using 10 ml allows for effective flushing of the medication through the tube, minimizing the risk of blockage and ensuring that the patient receives the full dose. It also helps in delivering the medication more evenly throughout the respiratory system, which is particularly important in emergency situations where rapid and effective treatment is critical.

Volumes lower than this may not provide enough dilution to adequately facilitate medication delivery, while higher volumes can unnecessarily increase fluid load, which is especially concerning in patients with respiratory distress or compromised cardiovascular function.
