Final answer:
The patient is experiencing cardiac arrest.
Step-by-step explanation:
The correct answer is A-Cardiac arrest.
Cardiac arrest occurs when the heart no longer pumps blood or pumps blood so poorly that vital organs can no longer function. This is a medical emergency requiring immediate intervention.
If a patient is not breathing, their central pulse is absent, and they have no life-threatening bleeding, it indicates that they are experiencing a cardiac arrest. In this condition, the heart stops pumping blood effectively, leading to a lack of oxygen supply to the body's vital organs.
To save the patient's life, immediate intervention is required, such as performing cardiopulmonary resuscitation (CPR) to manually compress the blood within the heart and push some of it into the pulmonary and systemic circuits. CPR should be continued until the patient regains spontaneous contraction or is declared dead by a healthcare professional.
