Questions Bank
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?
Blood glucose of 350 mg/dL
Anticoagulant therapy for 10 days
Hemoglobin of 8.5 g/dL
Heart rate of 100 beats/min and blood pressure of 100/60
The nurse is reviewing the patient's arterial blood gas results. The PaO? is 96 mm Hg, pH is 7.20, PaCO? is 55 mm Hg, and HCO? is 25 mEq/L. What might the nurse expect to observe on assessment of this patient?
Disorientation and tremors
Tachycardia and decreased blood pressure
Increased anxiety and irritability
Hyperventilation and lethargy
The nurse would identify which patient condition as a problem of impaired gas exchange secondary to a perfusion problem?
Peripheral arterial disease of the lower extremities
Chronic obstructive pulmonary disease (COPD)
Chronic asthma
Severe anemia secondary to chemotherapy
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?
An elevation of the total white cell count indicates generalized inflammation.
Eosinophil count will assist to identify the presence of a respiratory infection.
White cell count will differentiate types of respiratory bacteria.
Level of neutrophils provides guidelines to monitor a chronic infection.
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?
Chronic lung disease with increased carbon dioxide retention
Acute anxiety, hyperventilation, and decreased carbon dioxide retention
Decreased cardiac output with increased serum lactic acid production
Gastric drainage with increased removal of gastric acid
