Correct Answer is C
Explanation
A. Removing the tracheostomy tube completely is unnecessary and unsafe when capping.
B. Placing the cap without deflating the cuff will block airflow because the inflated cuff seals the airway.
C. Deflating the cuff before capping allows airflow around the tube, enabling the patient to breathe through the upper airway, which is necessary when using a trach cap.
D. Capping with the cuff inflated prevents air passage through the upper airway and may cause respiratory distress.
Correct Answer is C
Explanation
A. Measuring respiratory rate and lung function is part of respiratory assessment, not the focus of hemodynamic monitoring.
B. Kidney function and urine output are influenced by hemodynamics but are not directly measured by hemodynamic monitoring.
C. Hemodynamic monitoring is primarily used to assess cardiovascular function, including parameters like cardiac output, preload, afterload, and systemic vascular resistance. It helps guide fluid and medication therapy in critically ill patients.
D. Acid-base status is assessed via arterial blood gases, not hemodynamic monitoring.
