A client has been placed on a mechanical ventilator. The PCP has ordered the ventilator to be set at a respiratory rate of 28 breaths /min. The nurse questions the order, citing concerns about which acid-base problem?
Base deficit (HCO3): Acidosis
Acid excess (CO2): Acidosis
Base excess (HCO3): Alkalosis
Acid deficit (CO2): Alkalosis
The Correct Answer is B
A. Base deficit (HCO3): Acidosis: A base deficit indicates metabolic acidosis, but respiratory acidosis is more likely with the high rate of ventilation.
B. Acid excess (CO2): Acidosis: This is the correct answer. A high respiratory rate can lead to hyperventilation, decreasing CO2 levels and causing respiratory alkalosis, which may be a concern with an elevated rate.
C. Base excess (HCO3): Alkalosis: This would indicate metabolic alkalosis, but it is not as related to ventilator settings.
D. Acid deficit (CO2): Alkalosis: If the CO2 level is too low due to hyperventilation, this can lead to alkalosis, which the nurse is questioning here.
