A patient in cardiac arrest experiences return of spontaneous circulation. As part of post-cardiac arrest care, the patient is receiving mechanical ventilation at an initial rate of 10 breaths/min and a fraction of inspired oxygen (FiO2) of 0.30. Which finding(s) would indicate the need for change in the ventilator settings to optimize the patient's ventilation and oxygenation? SaO2 96% SaO2 90% PaCO2 48 mmHg ETCO2 55 mmHg ETCO2 40 mmHg {Ans: SaO2 90% PaCO2 48 mmHg ETCO2 55 mmHg Mechanical ventilation should be started at a rate of 10 breaths per minute and adjusted as necessary to keep carbon dioxide levels in physiologic range (PaCO2 between 35 and 45 mmHg or monitored using ETCO2). The minimum fraction of inspired oxygen necessary to maintain an SaO2 of 94% to 99% is used.}A 35-year-old female patient's ECG is consistent with STEMI. The ECG reveals a new ST-segment elevation at the J point in leads V2 and V3 of at least which size? 0.10 mV 0.15 mV 0.2 mV 0.25 mV {Ans: 0.15 mV New ST-segment elevation at the J point in leads V2 and V3 of at least 0.15 mV (1.5 mm) in women 40 years or younger is considered
