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

Answer and Explanation

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.
