Which of the following patients is considered to be breathing adequately?

• A. A conscious female with facial cyanosis and rapid, shallow respirations
• B. A conscious male with respirations of 18 breaths/min and reduced tidal volume
• C. A conscious male with respirations of 19 breaths/min and pink skin
• D. An unconscious 52-year-old female with snoring respirations and cool, pale skin

Answer: (C)

Breathing adequately refers to the ability of a person to maintain sufficient oxygenation and ventilation, characterized by normal respiratory rate, adequate depth of breathing, and the absence of signs of respiratory distress or inadequate oxygenation.

In this case, the patient who is a conscious male with a respiratory rate of 19 breaths per minute and pink skin is considered to be breathing adequately. A normal respiratory rate for adults typically ranges between 12 to 20 breaths per minute, which indicates that his breathing frequency falls within the normal range. The presence of pink skin further suggests good oxygenation, as cyanosis (a bluish color typically seen in inadequate oxygenation) is not present. This combination shows that the patient is effectively breathing, having an appropriate depth and rate of ventilation.

Other options describe conditions that may indicate inadequate breathing. For instance, the first option presents a patient with cyanosis and rapid, shallow respirations, both of which suggest poor oxygenation and ineffective breathing. The second option features a patient with reduced tidal volume, which could signal insufficient ventilation despite a seemingly normal respiratory rate. The last option describes an unconscious patient with snoring respirations, which can indicate airway obstruction, and pale skin, indicating potential inadequate perfusion.

Thus, the option indicating the
