Which of the following is a component of the four Cs of physiologic patient management?

• A. Control
• B. Collaboration
• C. Caring
• D. Confidence

Answer: (A)

Maintaining the patient’s physiologic state is about exerting direct control over the body's responses during care. In physiologic patient management, the four Cs point to different dimensions of how care is delivered, and control is the one that specifically refers to actively regulating physiological variables to keep them within safe, target ranges. This includes monitoring and adjusting vital signs, oxygenation, ventilation, heart rate, blood pressure, and pain or stress responses as interventions are applied.

Collaboration, caring, and confidence are essential supporting elements—working with the team, showing empathy, and having trust in yourself and the plan—but they describe the behavior and context of care rather than the mechanism of regulating the patient’s physiology. The act of adjusting medications, fluids, or other interventions to stabilize physiology embodies the control aspect of physiologic management.
