Case #4 Dillon is a 55 lb., 6-year-old male who fell into a fresh water lake while duck hunting with his father. Dillon was unaccounted for 15-20 minutes until his body was found floating face down in the water. He was immediately pulled out and basic life support was started. Upon arrival at the hospital, his ABG results were as follows: pH = 6.90; P.O₂ = 49 mmHg; PCO₂ = 54 mmHg; and HCO3 = 24 mEq/L. 1. What is Dillon's acid-base disturbance? acid nam TPCO₂ HLU 2. What is the specific cause of his acid-base disturbance? Explain your answer. 3. In the hospital, ventilatory support is provided with PEEP (positive end- expiratory pressure) and Dillon's latest ABG are: PO₂ = 88 mmHg, CO₂ = 38 mmHg, HCO3 = 10 mE/L, pH = 6.99. What would you attribute his current acid/base status to? Explain.

Case #4
Dillon is a 55 lb., 6-year-old male who fell into a fresh water lake while duck hunting
with his father. Dillon was unaccounted for 15-20 minutes until his body was found
floating face down in the water. He was immediately pulled out and basic life support
was started. Upon arrival at the hospital, his ABG results were as follows: pH = 6.90;
P₂O₂ = 49 mmHg; PCO₂ = 54 mmHg; and HCO3 = 24 mEq/L.

3. In the hospital, ventilatory support is provided with PEEP (positive end-

mmHg, HCO3- = 10 mE/L, pH = 6.99. What would you attribute his current
acid/base status to? Explain.
4. The doctors order a continuous ECG monitor and a blood chemistry panel to
evaluate Dillon's serum electrolyte levels. The doctor explains to the critical
care nurse that he is concerned about a redistribution or transmembrane shift
of electrolytes. Which particular electrolyte is the doctor most concerned
about and how would that affect Dillon's cardiac function?
