Exhibits Choose the most likely options for the information missing from the statement by selecting from the lists of options provided. When the laboratory results are available, the practical nurse (PN) would expect the child to have dropdown related to dropdown during the submersion.

Respiratory acidosis The laboratory results show a pH of 7.31, which is below the normal range of 7.35-7.45, indicating acidosis. Additionally, the PaCO2 is elevated at 51 mmHg, which is above the normal range of 35-45 mmHg, pointing towards a respiratory cause of the acidosis. Carbon dioxide retention During the submersion, the child likely experienced impaired ventilation, leading to hypoventilation and subsequent retention of carbon dioxide. This retention of CO2 contributes to respiratory acidosis.
