26. You are receiving a radio report from an EMS team en route with a patient who
may be having an acute stroke. The hospital CT scanner is not working at this
time. What should you do in this situation?

patient’s blood pressure is 102/59 mm Hg, the heart rate is 230/min, the respiratory rate
is 16 breaths/min, and the pulse oximetry reading is 96%. The lead II ECG is displayed
below. A patent peripheral IV is in place. What is the next action?
A. Acquisition of a 12-lead ECG
B. Vagal maneuvers
C. Procedural sedation
D. Immediate defibrillation
28. A 49-year-old man has retrosternal chest pain radiating into the left arm. The
patient is diaphoretic, with associated shortness of breath. The blood pressure
is 130/88 mm Hg, the heart rate is 110/min, the respiratory rate is 22 breaths/min,
and the pulse oximetry value is 95%. The patient’s 12-lead ECG shows STsegment elevation in the anterior leads. First responders administered 160 mg
of aspirin, and there is a patent peripheral IV. The pain is described as an 8 on a
scale of 1 to 10 and is unrelieved after 3 doses of nitroglycerin. What is the next
action?
A. Administer an additional dose of aspirin.
B. Administer an additional nitroglycerin tablet.
C. Administer high-flow oxygen via an oxygen mask.
D. Administer 2 to 4 mg of morphine by slow IV bolus.
29. A 56-year-old man reports that he has palpitations but not chest pain or
difficulty breathing. The blood pressure is 132/68 mm Hg, the pulse is 130/min
and regular, the respiratory rate is 12 breaths/min, and the pulse oximetry
reading is 95%. The lead II ECG displays a wide-complex tachycardia. What is
the next action after establishing an IV and obtaining a 12-lead ECG?
A. Administration of IV epinephrine
B. Seeking expert consultation
C. Procedural sedation
D. Synchronized cardioversion
30. A postoperative patient in the ICU reports new chest pain. What actions have
the highest priority?
A. Administer an IV fluid bolus and obtain arterial blood gas.
B. Start dopamine at 2 mcg/kg per minute and obtain a chest x-ray.
C. Send blood to the laboratory for chemistry and cardiac enzymes.
