Exam Preview for 2352: Arterial Blood Gas (ABG) Interpretation: A N

Arterial Blood Gas (ABG) Interpretation: A New Look

Please note: exam questions are subject to change.

1. The most recent blood gas sample demonstrates significant respiratory acidosis. What may be the greatest contributor to acidosis? Respiratory depressant causing hypoventilation Suctioning the endotracheal tube Respiratory depressant causing hyperventilation Hypotension
2. A patient has the following blood gas results: pH 7.31, PaCO2 58, PaO2 80, HCO3- 30. What is the best interpretation of the ABG result? Metabolic acidosis with partial compensation Respiratory acidosis with partial compensation Respiratory acidosis without compensation Respiratory alkalosis with partial compensation
3. A patient has the following blood gas results: pH 7.51, PaCO2 26, PaO2 85, and HCO3 16 while on positive pressure ventilation. What is the appropriate intervention? Decrease ventilation Keep the settings the same Wean FIO2 Give Bicarbonate
4. Why is it crucial to expel air bubbles from an ABG sample as soon as possible? Air bubbles enhance sample stability Air bubbles have no impact on results Air bubbles may introduce significant errors Air bubbles improve sample mixing
5. What is the purpose of using dry electrolyte-balanced heparin in blood gas syringes? Enhance blood clotting Prevent coagulation in the sampler and analyzer Increase the risk of pH variation Extend the analysis window
