Assessment Quiz 2

1. A 55-year-old man is found down and unresponsive to verbal commands when you tap on both of his shoulders. His respiratory rate is 16 breaths/minute, and his heart rate is 65 bpm. What should you do?

2. A 55-year-old man is found down and unresponsive to verbal commands when you tap on both of his shoulders. His respiratory rate is 16 breaths/minute, and his heart rate is 65 bpm. What should you do?

3. A 60-year-old man is brought to the emergency department unresponsive. He has the following vital signs: HR = 100 bpm, BP = 100/80 mm Hg, RR = 12/min, T = 36.8°C, oxygen saturation = 100%. Blood sugar level = 30 mg/dL. A 12-lead ECG records the following tracing:

What is the treatment of choice for this patient?

4. A 71-year-old woman undergoes hip replacement surgery. On the third hospital day, she suddenly develops chest pain and difficulty breathing. A ventilation/perfusion scan reveals two segmental mismatched defects in the right middle lobe. After the test, the patient goes into cardiac arrest and expires. What is the likely cause of the patient’s demise?

5. A cardiac arrest patient has achieved a return of spontaneous circulation after 25 minutes of cardiopulmonary resuscitation. He is presently comatose. The neurologist wants to assess the patient’s prognosis and orders a CT scan of the brain. If the CT scan taken within 2 hours after cardiac arrest shows a marked reduction of the gray-white ratio, what can the neurosurgeon conclude of this finding?

6. A comatose patient was revived after an unwitnessed cardiac arrest. After reviewing the patient’s brain CT scan, the neurosurgeon concludes that this patient’s neurologic outcome is poor. The patient has a gray-white ratio of 0.5 on a CT scan of the brain. What can you conclude in this finding?

7. A neurologist is projecting the likely outcome of a 72-year-old man that has been revived 15 minutes after cardiac arrest. Which of the following are clinical findings or tools that can help to conclude that this patient has a good prognosis?

8. A patient has achieved a return of spontaneous circulation (ROSC) after 15 minutes of ACLS. She is comatose and is admitted to the ICU with targeted temperature management. When is the most appropriate time to perform prognosticating tests in this situation?

9. A patient in cardiac arrest is successfully intubated in the ED. While performing 2 cycles of CPR, waveform capnography measures pressures at 9 mm Hg. What is your next course of action?

10. A patient in cardiac arrest secondary to severe hypothermia has achieved return of spontaneous circulation. At what targeted temperature should the patient be maintained, provided that there are no contraindications?
