How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Which medication class is used in a prescribed inhaler or nebulizer to treat bronchospasm?

Answer: Short-acting beta agonist bronchodilator (for example, albuterol). Relaxes bronchial smooth muscle by stimulating beta-2 receptors, rapidly relieving acute bronchoconstriction.

Flashcard 2: What is the EMT indication for assisting with a patient's prescribed nitroglycerin?

Answer: Suspected cardiac chest pain with systolic BP adequate per protocol and no contraindications. Relieves vasospasm and reduces preload in stable patients to alleviate myocardial oxygen demand.

Flashcard 3: Identify the correct EMT action when a patient with wheezing cannot speak and has minimal air movement.

Answer: Begin assisted ventilations with BVM and high-flow oxygen; prepare for rapid transport. Manages respiratory failure by ensuring adequate oxygenation and ventilation when spontaneous efforts are insufficient.

Flashcard 4: What is the most common and expected side effect of nitroglycerin that you should reassess for?

Answer: Headache and decreased blood pressure. Occurs due to vasodilation effects, requiring monitoring to ensure hemodynamic stability post-administration.

Flashcard 5: Which symptom is a common atypical presentation of acute coronary syndrome in older adults or diabetics?

Answer: Shortness of breath or weakness without chest pain. Occurs due to altered pain perception in these populations, presenting as equivalents to classic angina symptoms.

Flashcard 6: What is the immediate EMT priority when a patient has severe respiratory distress and cannot speak full sentences?

Answer: Open and maintain airway; provide high-flow oxygen and ventilate as needed. Addresses life-threatening airway compromise and hypoxia by ensuring patency and supporting ventilation to improve oxygenation.

Flashcard 7: Which medication use is an absolute contraindication to nitroglycerin due to severe hypotension risk?

Answer: Recent phosphodiesterase-5 inhibitor use (for example, sildenafil). Causes dangerous synergistic vasodilation when combined with nitroglycerin, leading to profound hypotension.

Flashcard 8: What is the most important differentiator between respiratory distress and respiratory failure?

Answer: Respiratory failure has inadequate ventilation or oxygenation with fatigue/AMS. Marks progression to life-threatening state where compensatory mechanisms fail, evidenced by exhaustion and mental status changes.

Flashcard 9: What is the EMT indication for administering aspirin to a chest-pain patient per protocol?

Answer: Suspected acute coronary syndrome with no allergy or active bleeding. Inhibits platelet aggregation to prevent thrombus progression in suspected myocardial infarction without bleeding risks.

Flashcard 10: What is the hallmark presentation of hyperventilation syndrome in an anxious patient?

Answer: Rapid deep breathing with lightheadedness and tingling of hands or lips. Caused by hypocapnia from excessive ventilation, leading to respiratory alkalosis and paresthesia in extremities.

Flashcard 11: Which intervention is appropriate for suspected hyperventilation syndrome after ruling out serious causes?

Answer: Coach slow breathing and provide reassurance; do not use a paper bag. Restores normal CO2 levels safely without risking hypoxia, as paper bags can cause rebreathing and complications.

Flashcard 12: Which assessment finding most strongly supports a diagnosis of asthma rather than CHF?

Answer: Wheezing with a history of asthma and no dependent edema. Points to reactive airway disease without signs of fluid overload or cardiac involvement typical of congestive heart failure.

Flashcard 13: Which breath sound is most consistent with fluid in the lungs (pulmonary edema)?

Answer: Crackles (rales). Arises from air bubbling through alveolar fluid, commonly associated with left-sided heart failure or other causes of fluid overload.

Flashcard 14: What does cyanosis generally indicate about oxygenation or perfusion status?

Answer: Inadequate oxygenation and possible hypoxia. Reflects deoxygenated hemoglobin in peripheral tissues, often from hypoxemia, hypoventilation, or circulatory impairment.

Flashcard 15: Which breath sound is most consistent with lower-airway bronchospasm (asthma or COPD)?

Answer: Wheezing. Results from turbulent airflow through constricted bronchioles due to inflammation and smooth muscle spasm in reactive airway diseases.

Flashcard 16: Which breath sound suggests upper-airway obstruction and is a high-priority finding?

Answer: Stridor. High-pitched inspiratory sound from partial upper airway blockage, often due to edema or foreign body, demanding urgent intervention.

Flashcard 17: What ventilation device should you use for a patient with inadequate breathing and a pulse?

Answer: Bag-valve mask ventilation with supplemental oxygen. Supports inadequate tidal volume and rate to prevent hypoxia and hypercapnia while maintaining circulation.

Flashcard 18: Which finding most strongly suggests cardiogenic shock rather than uncomplicated angina?

Answer: Hypotension with signs of poor perfusion (cool, clammy skin; altered mentation). Indicates pump failure with systemic hypoperfusion, distinguishing from stable ischemia without circulatory compromise.

Flashcard 19: What is the most appropriate oxygen device for a patient with mild dyspnea who is breathing adequately?

Answer: Nasal cannula. Delivers low-flow oxygen (1-6 L/min) comfortably for stable patients without need for higher concentrations.

Flashcard 20: What oxygen device is preferred for a patient with moderate to severe dyspnea who is breathing adequately?

Answer: Nonrebreather mask. Provides high-concentration oxygen (up to 90-100%) via reservoir bag to maximize delivery for hypoxemic patients.

Flashcard 21: Identify the correct EMT action when a patient has chest pain, pale skin, and a systolic BP of $84$ mmHg.

Answer: Do not give nitroglycerin; provide oxygen as needed, treat shock, rapid transport. Avoids nitroglycerin due to hypotension risk, focusing on supportive care and expedited advanced intervention.

Flashcard 22: What is the classic symptom pattern for acute coronary syndrome chest discomfort?

Answer: Pressure-like substernal pain possibly radiating to jaw or left arm. Describes ischemic myocardial pain from coronary artery occlusion, often with referred pain due to shared nerve pathways.

Flashcard 23: What is the classic triad of signs for anaphylaxis that requires rapid treatment?

Answer: Respiratory distress, hypotension/shock, and skin or mucosal findings. Indicates severe systemic allergic reaction involving respiratory, cardiovascular, and integumentary systems, requiring immediate epinephrine.

Flashcard 24: Which assessment finding most strongly supports CHF with pulmonary edema rather than asthma?

Answer: Crackles with hypertension and possible dependent edema. Suggests left ventricular failure leading to alveolar fluid accumulation, differentiated from bronchospasm by edema and vital signs.

Flashcard 25: Which option best describes the priority intervention for suspected pulmonary edema with severe dyspnea and crackles?

Answer: High-flow oxygen and ventilatory support as needed; position upright if tolerated. Improves oxygenation and reduces work of breathing in acute decompensated heart failure, with positioning aiding venous return.
