Correct Answer is C
Explanation
A. Infection prevention is managed through sterile technique and proper tracheostomy care, not by using a one-way valve cap.
B. A one-way valve cap does not deliver oxygen; in fact, it requires that the patient be able to breathe through their upper airway.
C. The purpose of a one-way valve cap (such as a Passy-Muir valve) is to facilitate speech by allowing air to enter through the tracheostomy but forcing exhaled air through the vocal cords and upper airway, enabling phonation and improved communication.
D. Suctioning is performed through the tracheostomy tube, but the one-way valve cap is not designed to assist in that process.
Correct Answer is D
Explanation
A. Superior vena cava pressure reflects right atrial pressure, not wedge pressure.
B. The aorta has its own pressures, unrelated to wedge pressure.
C. Right atrial pressure is measured separately, not via wedge pressure.
D. Pulmonary artery wedge pressure (PAWP) reflects the pressure in the left atrium and indirectly estimates left ventricular end-diastolic pressure, indicating left heart preload.
