Cardiopulmonary Resuscitation (CPR) Practice 2026 - Free CPR Practice Questions and Study Tips.

Administering intratracheal drugs during CPR is done to enhance the effectiveness of resuscitation efforts, particularly when intravenous access is not possible. The correct frequency is every 3-5 minutes, which aligns with the need for timely drug administration to support cardiac function and overall resuscitation efforts.

The rationale for this frequency is tied to the pharmacokinetics of the drugs used; administering them at 3-5 minute intervals allows for timely peaks in drug concentration, promoting better outcomes during the critical moments of cardiac arrest. This interval also corresponds to the cycles of CPR that allow for safety and reassessment of the patient's condition.

Inappropriate frequencies, such as continuous administration or too infrequent intervals, could lead to ineffective resuscitation. Continuous administration may not allow for adequate evaluation of the patient's response, while administering drugs every 10-15 minutes might delay action during a critical time when rapid intervention is necessary. The method of drug administration, the clinical setting, and the patient's response to therapy all play crucial roles in effective CPR management.
