The patient was admitted to the ICU in respiratory acidosis secondary to smoke inhalation and exposure to caustic gases.After placement of an endotracheal tube and connection to a mechanical ventilator,the arterial blood gas results are pH = 7.28,PaO2 = 85,PaCO2 = 60.What changes to care does the nurse anticipate?

A) Wean the patient from the ventilator.
B) Increase the concentration of oxygen delivered.
C) Decrease the concentration of oxygen delivered.
D) Increase the number of breaths per minute on the ventilator.

Respiratory Acidosis

A condition where there is an excess of carbon dioxide in the blood, leading to a lower pH level and causing the blood to become more acidic.

Arterial Blood Gas

Arterial blood gas is a blood test that measures the levels of oxygen and carbon dioxide in the blood from an artery, used to assess the effectiveness of a person's respiratory function.

Mechanical Ventilator

A device used to assist or control breathing by delivering air into the lungs.

  • Initiate and set priorities for nursing actions for patients who have impaired oxygen levels and require support from mechanical ventilators.

Final Answer :
D
Explanation :
The patient is still in a state of respiratory acidosis and is not ready for extubation and weaning from the ventilator.The PaO2 is adequate,so there is no need to increase the delivered oxygen concentration.The PaO2 is adequate so there is no need to decrease the delivered oxygen concentration.Increasing the number of breaths per minute provided by the mechanical ventilator will help the patient to blow off more carbon dioxide,which will result in an improved pH.
