Cаse Yоu аre а nurse wоrking within the pediatric unit оf your local hospital. The charge nurse receives a call from the Children’s clinic reporting a direct admission is expected due to respiratory distress. Upon arrival, you note a 3-month female appears to be in respiratory distress. Two adults are present with the infant and state they are mother and father. Initial vital signs are 99.2 F axillary, 135, 72, BP not obtainable, SaO2 82% on room air. Based on the case initial intake findings provided above, your patient's critical physiological need is:
