ANSWERS | DNAP 717 EXAM 3 STUDY GUIDE
& PRACTICE TEST 2026/2027

1 of 43




Term



normal range for:
pH, PaCO2, and HCO3



Give this one a go later!



- pH - 7.35-7.45

- increased airway pressure
- PaCO2 - 35-45 mmHg
- altered V/Q patterns

- HCO3 - 22-26 mEq/L




- ↑ intraathoracic pressure
it can redistribute blood flow to
- ↓ venous return
gravity dependent areas, increase
- ↓ SV
shunt and worsen V/Q
- ↓ CO

2 of 43

Term



• pH - > 7.45


• PaCO2 - decreased


• HCO3 - normal


• Caused by hyperventilation. Kidneys compensate by excreting HCO3



Give this one a go later!



- respiratory alkalosis
respiratory acidosis
- decrease ventilation




metabolic acidosis respiratory alkalosis

Term



what is NOT an indication for PPV?



Give this one a go later!



- ↑ intraathoracic pressure
it can redistribute blood flow to
- ↓ venous return
gravity dependent areas, increase
- ↓ SV
shunt and worsen V/Q
- ↓ CO




- Hypoxemia


*however, Hypoxemia without - increased airway pressure
CO2 retention is a pulmonary - altered V/Q patterns
problem and PPV improves
oxygenation


Don't know?




4 of 43

Term



normal ventilation is driven by ___ pressure
