Cardiopulmonary Resuscitation (CPR) Practice 2025 – Comprehensive All-in-One Guide to Master Your CPR Skills!

The correct choice emphasizes the multitude of complications and systemic damage that can occur following a cardiac arrest and subsequent CPR. When the heart stops, various body systems, particularly those relying heavily on oxygenated blood, are put at significant risk.

The brain is one of the first organs to suffer from oxygen deprivation, which can lead to brain injury if blood flow is not restored quickly enough. The body can also experience disseminated intravascular coagulation (DIC), a serious condition in which small blood clots form throughout the body's small blood vessels, leading to multiple organ dysfunction. Renal failure is another possible outcome because the kidneys require a constant blood supply to function effectively, and the lack of oxygen can result in acute kidney injury. Lastly, gastrointestinal failure can occur as the blood flow to the gastrointestinal tract is reduced during cardiac arrest, which may impair its function following resuscitation.

These consequences highlight the critical interconnectedness of body systems and the complex physiological response to cardiac arrest and CPR efforts, where the effects are not isolated but can lead to a chain reaction of failures in multiple organ systems.
