During mechanical ventilation of a patient with COPD, the PaCO2 = 58 mm Hg and the minute ventilation = 5.5 L/min. The desired PaCO2 for this patient is 45 mm Hg. To what should the minute ventilation be changed? a) 6.0 L/min b) 6.6 L/min c) 7.1 L/min d) 8.0 L/min correct answer: C. Desired vt= known paco2 x known vt / desired paco2 A patient with CHF is being mechanically ventilated. The patient's current PaCO2 = 28 mm Hg, and the ventilator set rate is 16 per minute.

Tidal volume breathing correct answer: Facilitates removal of CO2 and replenishes O2 Alveolar ventilation correct answer: Amount of fresh gas reaching alveoli per minute, determined by tidal volume, dead space and RR Compliance correct answer: Higher lung inflates easily, lower lung inflation is difficult Surfactant correct answer: Prevents alveolar collapse, inhaling toxins decrease effectiveness Restrictive lung diseases correct answer: More pressure needed to meet volume O...

Which of the following structures will result in the most radiopaque shadow on a CXR a. aorta b. heart c. lungs d. ribs correct answer: d. ribs Your patient just had an anteroposterior chest film taken. When you view the film, what may be a consideration? correct answer: The heart may appear larger than it really is. What is indicated by blunting of the costophrenic angles seen on a PA or lateral CXR? correct answer: Excess pleural fluid What chest x-ray view is best used to id...

Radiolucent correct answer: X-rays pass through low density tissue. Cause shadow to turn darker. Radiopaque correct answer: X-rays pass through high density tissue. Leave the exposed film lighter. Air correct answer: Absorbs x-rays least and results in dark shadow (radiolucent) Bone correct answer: Absorbs most x-ray energy and results in white shadow (radiopaque) PA view correct answer: Most common way chest x-ray is taken Right lateral decubitus correct answer: Lying on ri...
