Cardiac EMT Quiz (Valentine's Day 2024)

What is the pathway of blood flow through the heart?

• aorta-->body-->left atrium-->tricuspid-->right atrium-->pulmonary valve-->pulmonary vein-->pulmonary artery--> left ventricle-->mitral valve-->right ventricle-->aortic valve-->vena cava

• Vena cava-->left atrium-->tricuspid valve-->left ventricle-->pulmonary valve-->pulmonary artery-->lungs-->pulmonary vein-->right atrium-->bicuspid valve-->right ventricle-->aortic valve-->aorta-->body

• Vena cava-->right atrium-->tricuspid valve-->right ventricle-->pulmonary valve-->pulmonary artery-->lungs-->pulmonary vein-->left atrium-->bicuspid valve-->left ventricle-->aortic valve-->aorta-->body

• Vena cava-->right atrium-->bicuspid valve-->right ventricle-->pulmonary valve-->pulmonary vein-->lungs-->pulmonary artery-->left atrium-->tricuspid valve-->left ventricle-->aortic valve-->aorta-->body

Answer explanation

What is the appropriate single dosage of nitroglycerin sublingually?

• 4 mg

• 0.4 mg

• 0.2 mg

• 2 mg

Answer explanation

Your patient is a 55 yo F living on Bell Road, experiencing left shoulder and jaw pain rated at a 7 of 10. She's alone and unaware of medical history. As a conscientious provider, you place your patient on a 12-lead EKG, and computer interpretation suggests a STEMI. You need to make a transport decision. Where are you taking your patient?

• Johnston-Willis

• St Francis

• MCV

• St Mary's

Your patient presents with JVD and peripheral edema. He reports difficulty breathing and you note that he is seated in the tripod position. He's on Lasix and reports a prior MI. Vital signs as follows: HR 110, BP 100/64, SP02 92% on room air, RR 22, GCS 15. What do you suspect?

• Left-sided heart failure.

• ST-elevated myocardial infarction.

• Right-sided heart failure.

• Pulmonary edema.

Answer explanation

You are dispatched for a patient found unconscious in bed by family members. Upon arrival on scene, you are directed to a back bedroom and find your patient supine in bed, unresponsive to verbal or painful stimuli. You assess simultaneously for a pulse and respirations and can't detect either. The patient's wife tells you he has no advanced directives and asks you if you can save him. You and your partner are working for a rural agency, and although additional help/ALS has been activated, resources are about 20 minutes away. Your next step is to:

• One of you should calm the wife while the other documents time of death.

• One of you should procure the AED while the other initiates CPR.

• You should begin compressions while your partner attempts to place a supraglottic airway.

• You should place a 12-lead and allow for computer interpretation of the rhythm before anything else.

Which two rhythms will your AED consider shockable?

• PEA and V-tach

• Asystole (flat-line) only

• Only V-tach

• V-tach and V-fib

Which BLS medication can cause a prolonged QT interval?

• Zofran (ondansetron)

• Oxygen

• Aspirin

• Albuterol

What is happening inside the body when we refer to "shock?"

• Excess emotion: The patient's experiencing excess stress and anxiety from an injury/traumatic event, leading to a physiological inability to perfuse.

• Bradypnea: The patient is breathing too slowly to take in sufficient oxygen for perfusion, therefore preventing the patient's tissues from receiving sufficient oxygenation and putting them in a hypoxemic state.

• Hypovolemia: Shock is always due to lack of volume.

• Hypoperfusion: The patient is, due to pump/cardiac failure, decreased volume, obstruction, or inappropriate regulation of distribution, isn't receiving nutrients/oxygen to all tissues.

Answer explanation

Your patient reports that he has a prescription for nitroglycerin due to a prior STEMI. Which are reasons you might not assist him to take a dose of his prescribed nitro? (Assume that the nitro is in date, belongs to him, etc.)

Select all that apply.

• The patient's heart rate is 82 bpm.

• The patient tells you he's had stents placed.

• The patient's blood pressure is 90/50.

• The patient reports pain in his jaw.

• The patient says he's been taking a medication called Cialis.

You are placing AED pads on a 2 y/o patient. Where will you place the pads?

• "Anterior-posterior" with one exactly between the shoulderblades and the other in the corresponding space on the anterior chest.

• You should initiate rescue breaths instead of performing any cardiac-related intervention.

• One just below the collarbone on the right side, one on the left side in the area of the fourth intercostal space.

• You should initiate CPR instead.
