While assessing a physician with a trans thoracic ultrasound exam, you observe an echo-free area above the patient's diaphragm. Which of the following is most consistent with this finding? A) pn... eumothorax B) pulmonary edema C) pleural effusion D) atelectasis Correct Answer: C) pleural effusion In a B-mode ultrasound exam, the presence of an echo-free or dark zone in a scanned dependent region (especially at or near the costophrenic angle) indicates a pleural effusion. If the effusion is large, lung tissue may appear as a solid organ due to compression atelectasis. In real-time, the consolidated lung tissue may actually be seen as moving in the surrounding effusion fluid as the chest expands and contracts. What is the normal range for intracranial pressure (ICP) in a supine adult? A) -2 to +6 mmHg B) +7 to +15 mmHg C) +16 to +24 mmHg D) +25 to +33 mmHg Correct Answer: B) +7 to +15 mmHg Ans In supine adults, the mean ICP normally ranges between 7 to 15 mm Hg. An ICP > 20 mm Hg for more than 5 to 10 minutes is considered abnormally high in an adult, with pressures > 25 mm Hg for a prolonged period of time associated with poor patient outcomes. A patient involved in a motor vehicle accident presents with respiratory distress. A chest x-ray confirms the presence of multiple rib fractures on the left side. Which of the following physical findings would be expected during palpitation of the chest? A) trachea deviated to the left B) paradoxical motion of the abdomen C) paradoxical motion of the left chest [Show More]
