Question 2

You are working in the ED, caring for a 55-year-old female patient with a long history of COPD. She is more short of breath today than usual, and states that she has an increased cough. She has a tympanic temperature of 99.8°F. You have drawn arterial blood gases with the patient on room air; when the report comes back, it shows that the patient has a PaO2 of 92 mmHg. Which of the following is most likely?

Accepted Answer

A)  You have inadvertently drawn a venous sample. 
B)  The patient is critically hypoxic and requires assisted ventilation. 
C)  This is the typical value for this patient. 
D)  The lab performed the test incorrectly.

B)  evaluating the heart's electrical conduction system for abnormalities. 
C)  determining stroke volume. 
D)  evaluating the effectiveness of cardiac contractions. 
A)  determining cardiac output. 
B)  evaluating the heart's electrical conduction system for abnormalities. 
C)  determining stroke volume. 
D)  evaluating the effectiveness of cardiac contractions.

Question 4

Your patient is a 16-year-old male who attempted suicide. He is unconscious and apneic, lying supine on a garage floor. The family states that they found the patient unconscious in the front seat of a car that was running in an enclosed garage. HR = 70, BP = 100/60, RR = 0. In addition to an IV of normal saline, which of the following is the most appropriate action?

Accepted Answer

A)  Intubate, remove the patient from the garage, and transport to a hospital with a hyperbaric chamber. 
B)  Remove the patient from the garage, initiate BVM ventilations with 100 percent oxygen, intubate, and transport to a hospital with a hyperbaric chamber. 
C)  Remove the patient from the garage, initiate BVM ventilations with 100 percent oxygen, intubate, and transport to the nearest facility. 
D)  Remove the patient from the garage, intubate, and transport to the nearest hospital. 
A)  Intubate, remove the patient from the garage, and transport to a hospital with a hyperbaric chamber. 
B)  Remove the patient from the garage, initiate BVM ventilations with 100 percent oxygen, intubate, and transport to a hospital with a hyperbaric chamber. 
C)  Remove the patient from the garage, initiate BVM ventilations with 100 percent oxygen, intubate, and transport to the nearest facility. 
D)  Remove the patient from the garage, intubate, and transport to the nearest hospital.

B)  left ventricular hypertrophy. 
C)  slowed conduction through the AV node. 
D)  myocardial injury. 
A)  hyperkalemia.
