Flashcard 1: What does the term tachypnea mean for an adult respiratory rate?
Answer: Respiratory rate greater than 20 breaths/min. Accelerated breathing compensates for hypoxia, acidosis, or increased metabolic demand in adults.
Flashcard 2: Calculate MAP for BP 90/60 mmHg using MAP=DBP+31(SBP−DBP).
Answer: 70 mmHg. The formula weights diastolic higher due to longer cycle phase, providing mean perfusion pressure.
Flashcard 3: What is the immediate action if a patient becomes pale, diaphoretic, and dizzy during orthostatic vitals?
Answer: Stop the test and place the patient supine. Symptoms suggest orthostatic hypotension, requiring immediate stabilization to prevent falls or syncope.
Flashcard 4: What is the normal adult pulse rate range (beats/min)?
Answer: 60–100 beats/min. This range indicates normal cardiac output at rest for adults, balancing metabolic needs without strain.
Flashcard 5: Calculate pulse pressure for BP 118/76 mmHg.
Answer: 42 mmHg. Pulse pressure is derived by subtracting diastolic from systolic, reflecting arterial dynamics.
Flashcard 6: What is the formula for mean arterial pressure (MAP) using SBP and DBP?
Answer: MAP=DBP+31(SBP−DBP). This approximation estimates average arterial pressure, crucial for assessing organ perfusion over the cardiac cycle.
Flashcard 7: What is the correct method to count respirations without alerting the patient?
Answer: Count after pulse while appearing to still assess the pulse. This technique prevents conscious alteration of breathing patterns, ensuring accurate rate assessment.
Flashcard 8: What is the normal adult systolic blood pressure range (mmHg)?
Answer: Approximately 90–120 mmHg. This range maintains adequate perfusion pressure in adults without indicating hypotension or hypertension.
Flashcard 9: What is the definition of pulse pressure?
Answer: Systolic pressure minus diastolic pressure. It quantifies the difference in arterial pressure during cardiac cycles, indicating stroke volume and vascular compliance.
Flashcard 10: What is the normal adult respiratory rate range (breaths/min)?
Answer: 12–20 breaths/min. This range reflects typical resting ventilation for healthy adults, ensuring adequate gas exchange without distress.
Flashcard 11: What does pulse oximetry (SpO₂) estimate in the blood?
Answer: Percent hemoglobin saturated with oxygen. It measures oxygen binding to hemoglobin, reflecting arterial oxygenation efficiency non-invasively.
Flashcard 12: Which pulse site is preferred to assess perfusion in an unresponsive adult?
Answer: Carotid pulse. Central pulses like carotid are more reliable in low-perfusion states common in unresponsive patients.
Flashcard 13: Which trend is more concerning: HR 88→110 with worsening mentation, or HR 110→88 with improved mentation?
Answer: HR 88→110 with worsening mentation. Rising heart rate with deteriorating mental status suggests decompensation, unlike stabilization in the reverse trend.
Flashcard 14: What is the normal adult diastolic blood pressure range (mmHg)?
Answer: Approximately 60–80 mmHg. This range supports sufficient end-organ perfusion while avoiding excessive cardiac workload in adults.
Flashcard 15: What four measurements make up the standard EMT set of vital signs?
Answer: Respirations, pulse, blood pressure, skin (color/temp/condition). These core indicators provide a comprehensive assessment of cardiovascular, respiratory, and perfusion status in emergency medical care.
Flashcard 16: What does the term tachycardia mean for an adult pulse rate?
Answer: Pulse rate greater than 100 beats/min. Elevated rates often signal compensatory mechanisms for stress, hypoxia, or cardiac issues in adults.
Flashcard 17: Identify the best indicator of clinical improvement: improved vital signs, improved skin signs, or both trending better together?
Answer: Both vital signs and skin signs trending better together. Concurrent improvements confirm overall perfusion and stability, more reliable than isolated changes.
Flashcard 18: Identify the Korotkoff sound change that defines diastolic blood pressure in adults.
Answer: Disappearance of sounds. This phase indicates laminar flow resumption when cuff pressure drops below diastolic, standard for adult measurement.
Flashcard 19: What does the term bradypnea mean for an adult respiratory rate?
Answer: Respiratory rate less than 12 breaths/min. Slowed ventilation can result from respiratory depression, CNS issues, or opioid effects in adults.
Flashcard 20: Identify the Korotkoff sound that defines systolic blood pressure.
Answer: First clear tapping sound. It marks the onset of turbulent blood flow as cuff pressure equals arterial systolic pressure.
Flashcard 21: What does capillary refill time greater than 2 seconds generally suggest?
Answer: Possible poor peripheral perfusion. Delayed refill reflects vasoconstriction or hypovolemia, compromising capillary blood flow.
Flashcard 22: Which pulse site is commonly used for routine assessment in a responsive adult?
Answer: Radial pulse. Peripheral pulses like radial are accessible and sufficient for monitoring in stable, alert patients.
Flashcard 23: What does the term bradycardia mean for an adult pulse rate?
Answer: Pulse rate less than 60 beats/min. Reduced rates may indicate cardiac depression, medication effects, or neurological issues in adults.
Flashcard 24: What is the normal SpO₂ range for a healthy adult at sea level?
Answer: Approximately 95%–100%. This level ensures optimal tissue oxygenation in healthy individuals breathing room air at standard atmospheric pressure.
