This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient kno...

Changes to the assessment data include RR- 24 TO 36 CXR clear to bilateral diffuse infiltrates ABG 40% face mask or 100% non-rebreather mask pO2 120 mm Hg to 56 mm Hg pCO2 33 mmHg to 56 mmHg pH 7.42 to 7.35 HCO3 24 meq/L to 27 mEq/L Which of the ff do these changes most likely represent A. aspiration pneumonia B. p...

The nurse observes that the patient's jugular veins distend in the semi-upright position to more than 5 cm above the sternal angle. This is an indication of: - correct answer -fluid volume overload. what is normal Pulmonary artery occlusion pressure (PAOP)? - correct answer -5-12 mmHg The resistance against which the left ventricle must pump to eject its volume is: - correct answer -systemic vascular resistance. When the tricuspid valve is open, central venous pressure reflects the fil...
