The nurse assesses the patient and notes the following findings: Respiratory rate: 32 breaths per minute Oxygen saturation: 86% on 2L nasal cannula Heart rate: 118 bpm Arterial blood gas (ABG) results: pH: 7.28 PaCO₂: 68 mmHg PaO₂: 50 mmHg HCO₃: 29 mEq/L The provider suspects acute respiratory failure.

Cоntrоlled field experiments with а vаriety оf species were used to test the effects of surfаce-deposit feeders on succession at the Skagit Flats, an intertidal sandflat in northern Puget Sound, off the coast of Washington State in the U.S.A. A tiny crustacean (Tanais sp.) and a segmented worm (Manayunkia aestuarina) were each grown alone in a control treatment and grown with a tube building organism (Hobsonia florida) to test successional effects. Abundance of the crustacean and the worm (y-axis) were measured over time (x-axis) in both treatments. The effect of H. florida on Tanais species and M. aestuarina was __________ for both.
