- A patient's oxygen saturation reading is 89% on room air. What is the most appropriate EMT response?
Answer: Administer supplemental oxygen and reassess the reading
An oxygen saturation of 89% is below the normal range (95-100%) and indicates hypoxemia requiring supplemental oxygen administration and reassessment. Choice A is incorrect as 89% is abnormal for any age. Choice C delays necessary treatment. Choice D assumes equipment error when the reading may be accurate and requires treatment.
- What does this vital sign trend suggest about your patient's response to treatment?
Answer: Patient is responding positively to treatment with improving stability
The vital signs show consistent improvement over time with decreasing blood pressure toward normal ranges, decreasing heart rate, and normalizing respiratory rate, indicating positive response to treatment and decreasing cardiovascular stress. Choice A is incorrect as the trends show improvement, not deterioration. Choice C misinterprets the improving trends. Choice D fails to recognize the significant positive changes occurring.
- What is the normal range for capillary refill time in adults?
Answer: Less than 2 seconds with immediate color return
Normal capillary refill time in adults is less than 2 seconds, indicating adequate peripheral circulation. Choice B (2-4 seconds) is delayed and may indicate circulatory compromise. Choice C (4-6 seconds) is significantly delayed and abnormal. Choice D (greater than 6 seconds) indicates poor circulation and potential shock.
- What is the normal respiratory rate range for a healthy adult at rest?
Answer: 12-20 breaths per minute with regular rhythm
The normal respiratory rate for a healthy adult at rest is 12-20 breaths per minute. Choice A (8-12) is too low and would be considered bradypnea. Choice C (20-28) is elevated and would be considered tachypnea. Choice D (28-35) is significantly elevated and indicates respiratory distress.
- Dizzy after diarrhea. Lying: HR 76, BP 128/82. Standing: HR 116, BP 102/60. What best describes this finding?
Answer: Orthostatic hypotension
Your blood pressure drops from 128/82 lying to 102/60 standing, a fall of 26 mmHg systolic and 22 mmHg diastolic, while your heart rate climbs from 76 to 116. That is orthostatic hypotension, often from volume loss due to diarrhea. A normal response to standing would keep blood pressure stable, making that the tempting wrong answer.
- A patient's skin is cool, pale, and diaphoretic. What does this combination of findings most likely indicate?
Answer: Sympathetic nervous system activation from shock or stress
Cool, pale, and diaphoretic skin indicates sympathetic nervous system activation, often from shock, stress, or cardiovascular compromise as the body diverts blood from the skin to vital organs. Choice A would not typically cause diaphoresis. Choice C would not explain the systemic nature of these findings. Choice D is less likely than the classic shock presentation described.
- What is the primary purpose of trending vital signs during patient care?
Answer: To identify patient condition changes and treatment effectiveness
Trending vital signs allows EMTs to identify whether a patient's condition is improving, deteriorating, or remaining stable, and whether treatments are effective. Choice A focuses on documentation rather than patient care. Choice C is about information transfer, not ongoing assessment. Choice D focuses on skill demonstration rather than patient benefit.
- After trauma, serial vitals: 110/70, HR 92; 98/64, HR 110; 84/50, HR 126. What do trends indicate?
Answer: Decompensated shock, BP low
Serial vitals show a dropping blood pressure (110/70 to 84/50) with a rising heart rate (92 to 126), meaning the body can no longer compensate for the shock. This is decompensated shock with low BP. The most tempting wrong choice is compensated shock with stable BP, but that would maintain blood pressure; here BP is clearly falling.
- Head injury: BP rises 140/90 to 170/110, HR falls 96 to 58, RR 12 to 8. What do trends indicate?
Answer: Rising intracranial pressure
A head injury with rising blood pressure, falling heart rate, and slowing respirations is Cushing's triad, a late sign of rising intracranial pressure. The body raises BP to maintain cerebral perfusion against swelling, which triggers bradycardia. "Improving brain perfusion" is tempting, but these trends indicate compression, not recovery.
- How frequently should vital signs be reassessed during transport of a stable patient?
Answer: Every 15 minutes unless patient condition changes significantly
For stable patients, vital signs should be reassessed every 15 minutes, with more frequent assessment if the patient's condition changes. This provides adequate monitoring without excessive intervention. Choice A is too frequent for stable patients. Choice B is more appropriate for unstable patients. Choice D provides insufficient monitoring during transport.
- A 65-year-old patient has a heart rate of 45 beats per minute. How should this finding be interpreted?
Answer: Bradycardia requiring assessment for underlying causes and symptoms
A heart rate of 45 bpm is bradycardia (below 60 bpm) and requires assessment for underlying causes, symptoms, and potential need for treatment. Choice A is incorrect as this is abnormally slow for any age. Choice C might apply to conditioned athletes but requires assessment in a 65-year-old. Choice D makes assumptions about the cause and duration without proper evaluation.
- What trend do these vital signs demonstrate?
Answer: Improving cardiovascular status with decreasing stress response
The vital signs show a consistent downward trend toward more normal values, suggesting the patient is relaxing and the initial stress response is diminishing. This is a positive trend. Choice B is incorrect as shock would show worsening vital signs. Choice C is incorrect as there's no indication of dangerous hypotension. Choice D fails to recognize the significant positive trend occurring.
- What do these vital signs and presentation most likely indicate?
Answer: Heat stroke requiring immediate cooling and emergency transport
The combination of hypotension, extreme tachycardia, tachypnea, hyperthermia (104°F), altered mental status, and hot dry skin in an athlete during practice indicates heat stroke, a life-threatening emergency requiring immediate cooling and transport. Choice A doesn't explain the hyperthermia and shock signs. Choice C underestimates the severity. Choice D doesn't account for the heat-related presentation.
- A patient has a heart rate of 150 beats per minute. What additional assessment is most important?
Answer: Determine if the rapid rate is regular or irregular
With severe tachycardia at 150 bpm, determining whether the rhythm is regular or irregular helps differentiate between different types of tachycardia and guides treatment priorities within EMT scope. While blood pressure and perfusion are important, identifying rhythm regularity is the most critical assessment to determine the nature of the tachycardia.
- When assessing blood pressure in a patient with a weak pulse, what technique modification should be used?
Answer: Consider palpation method if auscultation is difficult to hear
When a patient has a weak pulse, the Korotkoff sounds may be difficult to hear with auscultation, making the palpation method more reliable for obtaining at least a systolic pressure reading. Choice A addresses cuff size but not the weak pulse issue. Choice B may be necessary but doesn't address the detection problem. Choice D is not practical and doesn't solve the weak pulse assessment challenge.
- What vital sign change would be most concerning in a patient with suspected internal bleeding?
Answer: Heart rate increasing from 80 to 110 beats per minute
A significant increase in heart rate from 80 to 110 bpm suggests the cardiovascular system is compensating for blood loss, which is an early and concerning sign of shock development in internal bleeding. Choice A shows minimal blood pressure change. Choice C shows minimal respiratory change. Choice D shows slight temperature decrease which is less immediately concerning than cardiovascular compensation.
- A patient's blood pressure reading is 88/54 mmHg. How should this finding be classified?
Answer: Hypotensive blood pressure indicating potential shock
A blood pressure of 88/54 mmHg is hypotensive, with the systolic pressure well below 90 mmHg, indicating potential shock and requiring immediate assessment for underlying causes. Choice A is incorrect as this is well below normal ranges. Choices B and D are incorrect as this represents low, not high, blood pressure.
- What does this vital sign trend most likely indicate?
Answer: Progressive shock development requiring immediate intervention
The vital signs show classic signs of progressive shock: decreasing blood pressure, increasing heart rate, and increasing respiratory rate over time. This trend indicates cardiovascular compromise requiring immediate intervention. Choice A is incorrect as anxiety would not cause this progressive deterioration. Choice B is wrong as this is not a normal response. Choice D ignores the consistent downward trend across multiple measurements.
- With oxygen, RR drops from 30 to 18 and SpO2 rises from 86% to 96%. What should the EMT do next?
Answer: Continue current oxygen dose
The respiratory rate dropping and SpO2 rising to 96% show the oxygen therapy is effective, so maintain the current dose and reassess. Increasing flow or switching to a bag-valve-mask is only needed if the patient deteriorates. The tempting mistake is to remove oxygen because the patient improved, but improvement means treatment is working, not that it should be stopped.
- What do these vital signs most likely indicate?
Answer: Increased intracranial pressure causing Cushing's triad presentation
The combination of hypertension (180/110), bradycardia (58), and severe headache suggests increased intracranial pressure with Cushing's triad (hypertension, bradycardia, and irregular respirations). Choice A ignores the abnormal vital sign combination. Choice C would not typically cause this specific pattern. Choice D would more likely cause tachycardia and hypotension.
