A tall thin 25-year-old college student was admitted to the ER in moderate distress after suddenly developing a sharp pain in his left lower thoracic region. The pain was exacerbated by deep inspiration and radiated anteriorly, almost to the midline. The patient is mildly dyspneic and has episodes of nonproductive cough that seem to increase the chest pain. His trachea is shifted to the right of the midline. Vital Signs: BP= 150/82, HR= 96 beats/min, and respirations 28 breaths/min and shallow. On room air, his SpO2 was 89%, X-ray revealed a mediastinal shift to the right. The left side of the chest was hyperresonant to percussion, and the breath sounds were described as absent or faint on right side. They patient was placed on 50% venturi maks. ABG: pH 7.53, PaCO2 29 mm Hg, HCO3 21 mEq/L, PaO2 56 mm Hg, and SaO2 92%. CVP 10 mm hg MPAP 22 mm Hg PCWP 4 mm Hg CO 2 L/min PVR 300 dynes/sec/ SVR 700 dynes/sec/   The next step for this patient would be to

Social role theory was primarily developed by Alice Eagly.

During your patient assessment, you must zero and balance the patients right radial arterial line.  You note the patients radial pulse is weak distal to the line and capillary refill is slow.  Prior to performing a square wave test you with draw from the line and no blood return is noted.   Your next step is …

In the event of a tension pneumothorax, variations of pulse and blood pressure during inspiration and expiration are noted on the arterial line waveform.  This variation is noted to be

The following are causes of SvO2 < 60%, except?

During transport of a patient to CT, the non-invasive blood pressure monitor unexpectedly shuts down.  You are concerned about your patients blood pressure being too low.  While troubleshooting the monitor, you palpate the patients radial pulse noting a strong regular pulse pressure.  This would indicate?
