Oops! That's Not Right
Insufficient oxygen flow rate.
This muscular organ pumps blood through the pulmonary and systemic circulations
What is the heart
What is the normal resting heart rate range for most healthy adults?
A man tries to impress his friends by jumping from a roof and lands on his feet. He complains of severe heel pain. What bone is commonly fractured in this type of landing?
An EMT checks a blood pressure and hears the first Korotkoff sound at 138 mmHg and the last at 82 mmHg. They document 82/138. What did they do wrong?
Reversed the systolic and diastolic pressures
These tiny air sacs are the primary location where oxygen and carbon dioxide are exchanged
What are the alveoli?
A cardiac arrest patient is in ventricular fibrillation. What intervention should be delivered as soon as the AED advises it?
What is defibrillation
A patient tries to start a bonfire by pouring gasoline onto an existing flame. Their arm has blistering burns that are moist and extremely painful. What depth of burn is most consistent with these findings?
Superficial partial-thickness burns
A patient has a large piece of metal impaled in their thigh. An EMT pulls it out so they can apply a pressure dressing. What is the mistake?
Removed the impaled object
Damage to this part of the brainstem can severely disrupt the body's automatic control of breathing
What is the medulla oblongata?
An adult patient has a heart rate of 38, BP of 72/40, cool clammy skin, and altered mental status. Why is this heart rate dangerous in this patient?
What is inadequate cardiac output causing poor tissue perfusion?
A man drinks heavily, falls down a flight of stairs, and insists he is fine. He has slurred speech, vomits twice, and becomes increasingly confused. What serious injury must you suspect?
What is a traumatic brain injury, including possible intracranial hemorrhage?
An unconscious diabetic patient has a blood glucose of 34 mg/dL. An EMT attempts to administer oral glucose gel by squeezing it into the patient's mouth. What is wong?
Gave oral glucose to a patient who cannot protect their airway
A patient with a severe allergic reaction develops swelling of the airway, widespread vasodilation, and fluid leaking from blood vessels. What substance released by mast cells contributes to these effects.
What is histamine?
A patient has crackles in both lungs, severe shortness of breath, and pink, frothy sputum. What cardiac-related condition is most likely?
Acute cardiogenic pulmonary edema
A man punches a window during an argument. He has a deep wrist laceration with pulsatile bleeding and reports numbness in his fingers. What two major structures may have been injured?
What are an artery and a peripheral nerve?
An adult trauma patient is pale, diaphoretic, confused, and tachycardic, with a BP of 118/76. The EMT states, 'they aren't in shock because their blood pressure is normal.' What is the critical error?
Failed to recognized compensated shock
A patient with a large pulmonary embolism has adequate air movement into parts of the lungs, but blood cannot reach those alveoli effectively. What type of ventilation-perfusion problem is this?
What is increased alveolar dead space (v/q mismatch)
A patient describes crushing chest pressure radiating to their left arm, accompanied by nausea and sweating. What life-threatening cardiac condition should you suspect?
Acute Coronary Syndrome (ACS) - includes unstable angina and myocardial infarction
A man jumps into a shallow lake headfirst. He is awake, cannot move his arms or legs, and has a heart rate of 46 with a BP of 78/42. What type of shock should you supsect?
What is neurogenic shock?
