Question

Emergency medical responders are unable to obtain a peripheral IV for a patient in cardiac arrest. what is the next most preferred route for drug administration?

a) Intraosseous (IO)
b) Subcutaneous
c) Intramuscular
d) Endotracheal tube

Answer 1

The next most preferred route for drug administration when emergency medical responders are unable to obtain a peripheral IV for a patient in cardiac arrest is Intraosseous (IO). This route involves injecting drugs directly into the bone marrow, providing a quick and effective way for medication delivery in critical situations.

Step-by-step explanation:

The next most preferred route for drug administration when emergency medical responders are unable to obtain a peripheral IV for a patient in cardiac arrest is Intraosseous (IO).

When a peripheral IV cannot be obtained, IO access involves the injection of drugs directly into the bone marrow. This route provides a quick and effective way for medication delivery, especially in critical situations such as cardiac arrest.

For example, during cardiac arrest, IO access can be used to deliver medications like epinephrine or vasopressin directly into the bone marrow, where they can quickly reach the bloodstream and have an immediate effect in resuscitating the patient.
