2025|140 QUESTIONS WITH 100% ACCURATE SOLUTIONS
1. Occlusion of the right coronary artery would MOST likely result in:
sinoatrial node failure.
ectopic ventricular
complexes. sudden cardiac
arrest.
an increase in atrial kick
2. In a patient presenting with a type I second-degree AV block, what
would be the most appropriate initial management step in an emergency
setting?
Monitor the patient closely for any progression of the block.
Initiate CPR as the first response to the block.
Administer atropine immediately to increase heart rate.
Prepare for immediate defibrillation due to risk of cardiac arrest.
3. Which intervention is most appropriate for the treatment of a patient in
asystole?
Defibrillation
Atropine
Transcutaneous pacing
, Epinephrine
4. Describe how digoxin affects heart rate and why it may lead to symptoms
such as nausea and blurred vision in patients with atrial fibrillation.
, Digoxin slows down the heart rate and can cause side effects
like nausea and blurred vision due to its effects on cardiac
output and electrolyte balance.
Digoxin is a diuretic that helps reduce fluid overload, alleviating
nausea and blurred vision.
Digoxin has no effect on heart rate but can cause nausea and
blurred vision due to its interaction with other medications.
Digoxin increases heart rate and improves blood flow, reducing
symptoms of nausea and blurred vision.
5. What is the primary indication for transcutaneous cardiac pacing (TCP)?
First-degree AV block in a patient with abdominal pain.
Asystole after 10 minutes of adequate CPR.
Third-degree AV block in a patient with pulmonary edema.
Pulseless electrical activity at a rate of 50 beats/min.
6. A 39-year-old female presents with an acute onset of lightheadedness. The
cardiac monitor reveals a tachycardic rhythm at 170 beats/min with QRS
complexes that measure 0.08 seconds in duration. Despite vagal maneuvers and
adenosine, her cardiac rhythm remains unchanged. She is conscious
and alert, has a blood pressure of 118/72 mm Hg, and denies shortness of breath
or chest discomfort. You should:
perform synchronized cardioversion with 50 joules.
consider that her rhythm is ventricular in origin.
transport immediately and monitor her en route.
administer 150 mg of amiodarone over 10 minutes.
, 7. Why is it critical for a paramedic to assess for hemodynamic compromise
before taking further action in a cardiac emergency?
It ensures that the patient receives fluids before any other
intervention.
Assessing for hemodynamic compromise helps determine
the patient's stability and guides appropriate treatment
decisions.
It is a standard procedure that does not influence treatment
decisions.
It allows the paramedic to immediately administer medication
without further assessment.
8. Why is administering dopamine considered the most appropriate next step
in managing this patient’s condition?
Administering dopamine is primarily for pain relief in cardiac
patients.
Administering dopamine is a standard procedure before obtaining
an ECG.
Administering dopamine helps to improve blood pressure and
cardiac output in a patient with hypotension.
Administering dopamine is used to treat bradycardia in patients.
9. Describe how decreased stroke volume in left heart failure can lead
to symptoms such as suffocation and anxiety in a patient.
Decreased stroke volume in left heart failure results in increased
blood flow to the lungs, leading to suffocation.
Increased stroke volume in left heart failure causes anxiety due to
excess oxygen in the blood.
