Cardiology
This is the heart rhythm that originates in the sinoatrial node and has a rate of 60-100 beats per minute in adults.
Sinus Rhythm
This device is commonly used by providers to deliver high flow oxygen to patients in respiratory distress at a flow rate of 15lpm
non rebreather mask
This vital sign, measured in beats per minute, helps determine perfusion and cardiac status.
Pulse or heart rate
A patient presents with mild wheezing and shortness of breath during an asthma attack. You are limited to BLS interventions. Which medication would you use?
nebulized albuterol or inhaled bronchodilator
This condition occurs when the heart cannot pump enough blood to meet the body's needs, often causing shortness of breath, edema, and fatigue
Heart failure
This chronic respiratory disease is characterized by inflammation and narrowing of the airways, causing wheezing, shortness of breath, and coughing.
asthma
This primary survey step focuses on identifying life-threatening bleeding, airway compromise, and shock.
ABC
A patient is experiencing chest pain and suspected acute coronary syndrome. You have ALS capabilities. Which medication would you administer to reduce clot formation
aspirin
This arrhythmia is characterized by irregularly irregular rhythm with no distinct P waves on the ECG. It increases the risk of stroke if not treated.
atrial fibrillation
This condition involves fluid accumulation in the alveoli, often from infection or cardiac failure, and can cause crackles, dyspnea, and hypoxia.
pulmonary edema
A 58-year-old male suddenly becomes dizzy and diaphoretic. Monitor shows a wide-complex, irregular rhythm at 180 bpm. He is hypotensive and altered. What is your next critical intervention?
synchronized cardioversion
You are preparing to perform rapid sequence intubation. You need a sedative to induce unconsciousness and a paralytic to facilitate intubation. Examples include this sedative and this paralytic
What are etomidate (or ketamine) and succinylcholine (or rocuronium)
this enzyme rises within hours of myocardial cell death and is commonly used in the hospitals to confirm a heart attack
troponin
This type of medication, given during RSI, is used to induce unconsciousness before administering a paralytic agent.
sedative or induction agent (etomidate, ketamine)
Your patient is bradycardic at 34 bpm, hypotensive, and shows signs of altered mental status. Atropine has failed. What is your next critical intervention?
transcutaneous pacing
You have a patient who needs 0.5 mg of atropine. The vial contains 1 mg/mL. How many milliliters will you administer
0.5mL
ST segment elevation in leads II, II, and aVF suggests infarction in this region of the heart.
inferior myocardial infarction
This change in end-tidal CO₂, may indicate hypoventilation, respiratory depression, or worsening airway obstruction
Hypercapnia (increased CO2)
A patient with a history of asthma is in severe distress, speaking only 2-word sentences, wheezing, and has a silent chest on auscultation. What is your treatment plan?
high flow O2, nebulized bronchodilators, solumedrol
A patient weighs 70 kg and requires a loading dose of 0.6 mg/kg of etomidate for RSI. The vial concentration is 2 mg/mL. How many milliliters do you administer
21 mL
70 kg × 0.6 mg/kg = 42 mg total. Concentration 2 mg/mL → 42 ÷ 2 = 21 mL
