Which of the following identifies the "H's" in cardiac arrest treatment?

The correct identification of the "H's" in cardiac arrest treatment is essential for addressing causes that may contribute to or exacerbate the condition. The first answer encompasses the key factors involved in the differential diagnosis of a patient in cardiac arrest.

Hypovolemia refers to a reduced volume of blood, which can lead to inadequate perfusion and cardiac output. It is crucial to recognize and treat this condition in resuscitation to restore blood volume through fluid replacement.

Hypoxia indicates a deficiency in oxygen reaching the tissues, which can severely impact the heart's ability to function normally. Correcting hypoxia is vital, often through airway management and supplemental oxygen, to improve oxygen delivery to vital organs during cardiopulmonary resuscitation (CPR).

Hydrogen ions relate to acidosis, a condition that can occur due to various factors, including metabolic processes or prolonged cardiac arrest. Monitoring and managing acid-base balance can aid in restoring a more stable physiological state.

Hyperkalemia and hypokalemia refer to elevated or decreased potassium levels, respectively. Both conditions can significantly affect cardiac rhythm and function, making it vital to assess and correct any imbalances in potassium during resuscitation efforts.

Hypothermia refers to a decrease in body temperature, which can further
