OXYGENATION AND PERFUSION FINAL
STUDY GUIDE 2026 CORRECT SOLUTIONS
GRADED A+
⫸ Restlessness. Answer: An early indicator of hypoxia due to
decreased oxygenation of brain tissue.
⫸ Incentive spirometer usage. Answer: Instruct the patient to inhale
slowly and deeply through the mouthpiece to expand the lungs and
prevent atelectasis.
⫸ High Fowler's position. Answer: Promotes maximum lung
expansion and improves oxygenation for patients with impaired gas
exchange.
⫸ Decreased level of consciousness (LOC). Answer: Indicates
inadequate cerebral perfusion from low cardiac output.
⫸ Pursed-lip breathing. Answer: Slows exhalation, keeping airways
open longer and promoting gas exchange in COPD patients.
⫸ Oxygen saturation assessment. Answer: Should be assessed first in
a patient with dyspnea to determine severity before interventions.
