Vital Signs Quiz
Questions: 16 · 10 minutes
1. Why should the measurement site or method be recorded with a temperature reading?
The site determines whether temperature is a vital sign
Only one site can detect any change in body temperature
Oral, ear, forehead, rectal, and underarm methods can produce different readings
Readings from different sites always differ by exactly the same amount
2. A resting adult has a regular pulse of 72 beats per minute and no concerning symptoms. How does this compare with the commonly cited adult resting range?
It cannot be a resting pulse because resting rates are always below 70
It is below the commonly cited range of 80–120 beats per minute
It is above the commonly cited range of 40–60 beats per minute
It is within the commonly cited range of 60–100 beats per minute
3. What does a pulse oximeter primarily estimate?
The amount of carbon dioxide being exhaled with each breath
The pressure needed to circulate blood through the lungs
The percentage of hemoglobin in arterial blood carrying oxygen
The total volume of air moving through the lungs each minute
4. Why is body temperature better understood as a range rather than one fixed normal number?
All thermometers intentionally produce slightly random readings
A person's temperature normally changes by several degrees every few minutes
Temperature has meaning only when blood pressure is also measured
Time of day, measurement site, activity, and individual factors can affect it
5. Which range is commonly cited for the resting respiratory rate of a healthy adult?
12–20 breaths per minute
8–10 breaths per minute
4–8 breaths per minute
24–36 breaths per minute
6. A blood pressure cuff is too small for the person's upper arm. What effect is this most likely to have?
It may produce a falsely low body temperature reading
It may produce a falsely high blood pressure reading
It will measure pulse but not blood pressure
It will make the systolic and diastolic values identical
7. In the blood pressure reading 118/76 mmHg, which value is the systolic pressure?
76
118
42, the difference between the two numbers
194, the sum of the two numbers
8. A home device gives an unexpected vital-sign reading, but the person has no severe symptoms. What is the most sensible next step?
Assume the reading proves a medical condition
Ignore it because home devices never provide useful information
Change the result to match the person's usual reading
Repeat it using correct technique and seek professional guidance if it remains concerning
9. What does the systolic number in a blood pressure reading represent?
Pressure in the arteries while the heart relaxes between beats
Pressure in the arteries when the heart contracts
Pressure in the veins as blood returns to the heart
The number of heartbeats occurring each minute
10. Someone has just climbed several flights of stairs and wants a routine resting blood pressure reading. What should they do first?
Take the reading immediately before the pulse begins to slow
Drink a caffeinated beverage to stabilize circulation
Lie flat and raise both arms above the head
Sit quietly for at least several minutes before measuring
11. What does it mean when a pulse rhythm is described as irregular?
Every beat feels weaker than the beat before it
The pulse can be felt only on one side of the body
The intervals between beats are not consistently even
The rate increases normally during physical activity
12. How should a resting respiratory rate usually be measured?
Observe natural chest or abdominal rises while the person is at rest
Count only breaths that make the chest rise noticeably high
Ask the person to breathe as deeply as possible while counting
Have the person hold their breath first, then count recovery breaths
13. A person's radial pulse feels irregular. What is the most appropriate way to count it manually?
Count for a full 60 seconds while noting the rhythm
Count for 10 seconds and multiply by six
Count only the strongest beats for 30 seconds
Take three 5-second counts and use the highest
14. Which group contains the four traditional vital signs?
Temperature, pulse, respiratory rate, and blood pressure
Height, weight, body mass index, and waist circumference
Blood glucose, cholesterol, pulse, and temperature
Oxygen saturation, pain level, blood glucose, and body weight
15. A person becomes lightheaded whenever they stand. Which comparison would be most relevant for checking a position-related change in vital signs?
Temperature before and after drinking water
Blood pressure and pulse while lying down and again after standing
Respiratory rate before and after a meal
Oxygen saturation on the left hand and right hand at the same time
16. You find an adult who is unresponsive and not breathing normally. What should take priority over repeatedly measuring vital signs?
Waiting several minutes to see whether the readings normalize
Taking an oral temperature before moving closer
Activating emergency help and beginning appropriate emergency response
Recording three blood pressure measurements for comparison
