Why is monitoring respiratory status a nursing priority when a client with COPD is receiving oxygen? a. hyperventilation leading to respiratory alkalosis and loss of consciousness is a risk. b. sudden increase in arterial oxygen can precipitate diaphragmatic spasm. c. decreased arterial oxygen is the stimuls for breathing in a clinet with COPD d. oxygen administration can trigger reflex bronchospasm. Correct Answer c. decreased arterial oxygen is the stimuls for breathing in a clinet with COPD Decreased oxygen in the blood is the stimulus for breathing in a client with COPD. Therefore, if oxygen is administered there is the risk that respiratory arrest will occur because high oxygen saturation levels in the blood eliminate the stimulus for breathing. This is a particular risk with the administration of 100% oxygen. The normal stimulus to breathe is an increase in CO2 in the blood but the client with COPD has become insensitive to CO2 because of longterm elevated levels associated with the COPD.
