Exam 19: Gas Exchange

The nurse is reviewing the patient's arterial blood gas results. The PaO₂ is 96 mm Hg, pH is 7.20, PaCO₂ is 55 mm Hg, and HCO₃ is 25 mEq/L. What might the nurse expect to observe on assessment of this patient?

The nurse would identify which patient condition as a problem of impaired gas exchange secondary to a perfusion problem?

The nurse is assigned a group of patients. Which patient finding would the nurse identify as a factor leading to increased risk for impaired gas exchange?

The nurse is assessing a patient for the adequacy of ventilation. What assessment findings would indicate the patient has good ventilation? (Select all that apply.)

Which patient finding would the nurse identify as being a risk factor for altered transport of oxygen?

Which clinical management prevention Chapter would the nurse identify as representative of secondary prevention?

The nurse would identify which body systems as directly involved in the process of normal gas exchange? (Select all that apply.)

A 3-month-old infant is at increased risk for developing anemia. The nurse would identify which principle contributing to this risk?

The acid-base status of a patient is dependent on normal gas exchange. Which patient would the nurse identify as having an increased risk for the development of respiratory acidosis?

The nurse is assessing a patient's differential white blood cell count. What implications would this test have on evaluating the adequacy of a patient's gas exchange?
