PARAMEDIC FINAL LATEST
EXAM
Which of the following ECG waveforms represents ventricular
depolarization? - ANSWERS-QRS complex
Which of the following patients would MOST likely present with
atypical signs and symptoms of an acute myocardial infarction? -
ANSWERS-58-year-old diabetic woman
Which of the following statements regarding oxygen administration for a
patient experiencing an acute myocardial infarction is correct? -
ANSWERS-Treatment with oxygen should be individualized and
titrated to maintain the SpO2 level above 94%.
55-year-old man complains of severe pain between his shoulder blades,
which he describes as "ripping" in nature. He tells you that the pain
began suddenly and has been intense and unrelenting since its onset. His
medical history includes hypertension, and he admits to being
noncompliant with his antihypertensive medication. Which of the
following assessment findings would MOST likely reinforce your
suspicion regarding the cause of his pain? - ANSWERS-Difference in
blood pressure between the two arms

EXAM
You are dispatched to a residence at 2:00 AM for an elderly man with
shortness of breath. The patient tells you that he was suddenly awakened
with the feeling that he was smothering. You note dried blood on his
lips. The patient tells you that he has some type of "breathing problem,"
for which he uses a prescribed inhaler and takes a "heart pill." You
should suspect: - ANSWERS-left ventricular failure.
Depolarization, the process by which muscle fibers are stimulated to
contract, occurs when: - ANSWERS-cell wall permeability changes and
sodium rushes into the cell.
The right atrium, right ventricle, and part of the left ventricle are
supplied by the: - ANSWERS-right coronary artery
Atherosclerosis is a process in which: - ANSWERS-plaque infiltrates the
arterial wall, decreasing its elasticity and narrowing its lumen.
In contrast to the right side of the heart, the left side of the heart: -
ANSWERS-drives blood out of the heart against the relatively high
resistance of the systemic circulation.

EXAM
The left main coronary artery subdivides into the: - ANSWERS-left
anterior descending and circumflex arteries.
Cardiac-related chest pain may be relieved by: - ANSWERS-Nitro
The farther removed the conduction tissue is from the SA node: -
ANSWERS-the slower its intrinsic rate of firing
A 68-year-old male who has COPD presents with edema to his feet and
ankles, jugular venous distention, and an enlarged abdomen. What
should you suspect? - ANSWERS-right ventricular failure
A 69-year-old female presents with a sudden onset of shortness of breath
that woke her from her sleep. She is conscious, but anxious, and is
coughing up pink sputum. She can only speak in two-word sentences
and has cyanosis to her face. Her BP is 170/90 mm Hg, pulse rate is 130
beats/min, and respirations are 28 breaths/min. What should you do
first? - ANSWERS-Provide continuous positive airway pressure (CPAP)
classic sign of atrial flutter is: - ANSWERS-the presence of sawtooth F
waves.

EXAM
A decreased cardiac output secondary to a heart rate greater than 150
beats/min is caused by: - ANSWERS-decreases in stroke volume and
ventricular filling.
A major complication associated with atrial fibrillation is: - ANSWERS-
clot formation in the fibrillating atria.
A regular cardiac rhythm with a rate of 104 beats/min, upright P waves,
a PR interval of 0.14 seconds, and QRS complexes that measure 0.10
seconds should be interpreted as: - ANSWERS-sinus tachycardia
If a particular interval on the ECG graph paper is 1.5 small boxes in
width, the interval would be measured as: - ANSWERS-0.06 seconds
Which of the following differentiates an atrial rhythm from a sinus
rhythm? - ANSWERS-Varying shapes in P waves
Wandering Atrial Pacemaker - ANSWERS-may have variable PR
intervals.
