Which medical terminology word part provides the general meaning of the word?

Choice A rationale:

The client's respirations are faster and deeper than normal due to expelling too much carbon dioxide. This condition is known as hyperventilation. Hyperventilation can occur due to various reasons such as anxiety, pain, fever, or metabolic acidosis. When the body expels excessive carbon dioxide, it leads to respiratory alkalosis, resulting in faster and deeper breathing to compensate for the decrease in carbon dioxide levels in the blood.

Choice B rationale:

This option is incorrect. Hypoxemia, or low blood oxygen levels, typically leads to rapid, shallow breathing (tachypnea) rather than deep and fast respirations.

Choice C rationale:

This option is incorrect. Inflammation of the phrenic nerve does not directly affect the depth and rate of respirations. Phrenic nerve inflammation is more likely to cause pain during breathing or hiccups.

Choice D rationale:

This option is incorrect. Using intercostal muscles to breathe is a normal physiological process, especially during deep or labored breathing. However, it does not explain the specific situation described in the question, where the respirations are faster and deeper than normal.

The correct answer is Choice C.

Choice A rationale: Using a fire extinguisher is part of containment, but it follows evacuation. Attempting to extinguish before removing clients violates RACE protocol and risks patient injury from smoke or electrical fire.

Choice B rationale: Activating the fire alarm initiates emergency response but comes after client rescue. Per RACE (Rescue, Alarm, Contain, Extinguish), client safety is prioritized before system-wide alerts.

Choice C rationale: Moving clients to safety is the first step in fire response. It aligns with the “Rescue” phase of RACE, ensuring immediate protection from smoke inhalation, electrical hazards, and fire spread.

Choice D rationale: Confine by closing doors and windows is part of containment, which follows rescue and alarm activation. It helps limit fire spread but is not the initial priority in patient-centered emergencies.
