1. A 38-year-old man had severe diarrhea for weeks without
receiving medical attention. Arterial blood gas analysis showed a pH of 7.36,
PCO2 of 24 mm Hg, HCO3 − of 13 mEq/L, and BE of
−11 mEq/L. How would the RT assess this patient’s acid-base condition?
2. An automobile accident victim, previously healthy,
sustained a closed head injury with accompanying high ICP. Mechanical
ventilation in the intensive care unit is required, and the physician asks the
RT for input regarding ventilator strategies and what PaCO2 should be targeted?
