NBRC TMC PRACTICE EXAM | QUESTIONS WITH ACCURATE ANSWERS| EXPERT VERIFIED FOR GUARANTEED PASS | LATEST UPDATE 2024|2025 Which of the following is needed to calculate alveolar oxygen tension? A. VD/VT, PAO2 B. BP and FiO2 C. PetCO2 and PaO2 D. QS/QT, deadspace Correct Answer B. Barometric pressure, FiO2, and PaO2 are all included in the formula (BP stands for barometric pressure) L/min/m2 is the unit of measure for: A. Systemic vascular resistance B. Cardiac output C. Cardiac index D. Stroke volume Correct Answer C. A spontaneously breathing patient has the following arterial blood gas results: pH 7.38 PaCO2 42 mmHgPaO2 76 mmHgHCO3- 24 mEq/LBE 0 mEq/L Which of the following supplemental oxygen levels is most appropriate? A. 2 L/min nasal cannula B. 5 L/min nasal cannula C. non-rebreathing mask D. Venturi mask at 30% Correct Answer B. A patient who is showing signs of hypoxemia should receive supplemental oxygen. If the patient is not a COPD patient and the situation is not an emergency, then the proper supplemental oxygen is an adult therapeutic dose, which is 40% to 55%. Of the options available only 5 L/min nasal cannula will approach this. Other options are either insufficient or too much. Left heart failure would be manifested in which of the following values? A. CVP and mPAP B. mPAP and wedge pressure C. MAP and SVR D. cardiac output and wedge pressure Correct Answer D. The function of the left heart, specifically the left ventricle, is best assessed hemodynamically by looking at those values that precede and come after the left heart. In this case pulmonary capillary wedge pressure and cardiac output (or cardiac index) are the values found before and after the left heart. Which of the following findings is most closely associated with increased airway resistance? A. reduced SpO2 B. accessory muscle use C. altered P50 D. increased PetCO2 Correct Answer B.
