What is the normal resting adult pulse rate range?
70-110 beats per minute
60-100 beats per minute
50-70 beats per minute
40-90 beats per minute
The normal resting adult pulse rate is generally between 60 and 100 beats per minute. Rates below or above this range may indicate bradycardia or tachycardia, respectively.
What is the typical normal adult respiratory rate at rest?
20-30 breaths per minute
8-12 breaths per minute
12-20 breaths per minute
10-16 breaths per minute
A normal adult respiratory rate at rest is 12 to 20 breaths per minute. Values outside this range suggest abnormal breathing patterns.
What is considered a normal blood pressure for a healthy adult?
120/80 mmHg
140/90 mmHg
130/85 mmHg
110/70 mmHg
A blood pressure of 120/80 mmHg is widely accepted as the normal standard for healthy adults. Higher readings indicate prehypertension or hypertension.
Which device is used to measure blood pressure manually?
Pulse oximeter
Thermometer
Stethoscope
Sphygmomanometer
A sphygmomanometer is the manual instrument used with a cuff to measure blood pressure. The stethoscope is used in conjunction with it to auscultate Korotkoff sounds.
Which vital sign is measured using a thermometer?
Respiratory rate
Blood pressure
Heart rate
Body temperature
A thermometer measures body temperature, which is one of the core vital signs. It does not measure pulse, blood pressure, or respiration.
At which arterial site is the pulse most commonly assessed at the wrist?
Brachial artery
Radial artery
Temporal artery
Carotid artery
The radial artery, located on the thumb side of the wrist, is the most common site for assessing peripheral pulse rate. It is easily accessible and safe to palpate.
When selecting a blood pressure cuff for an adult arm, the bladder length should cover what percentage of the arm circumference?
80%
100%
50%
20%
The bladder length should cover about 80% of the arm circumference to ensure accurate blood pressure readings. A cuff that is too small or too large can yield erroneous values.
A patient has a blood pressure reading of 145/95 mmHg. How would this be classified?
Hypotension
Prehypertension
Stage 1 hypertension
Stage 2 hypertension
A blood pressure of 145/95 mmHg falls into the stage 2 hypertension category (140 - 159/90 - 99 mmHg). This level requires medical evaluation and possible intervention.
A respiratory rate of 30 breaths per minute is termed:
Bradypnea
Apnea
Tachypnea
Hyperventilation
Tachypnea refers to an abnormally rapid breathing rate, typically over 20 breaths per minute in adults. Bradypnea is slow breathing, apnea is absence of breathing.
What is the normal resting heart rate range for a healthy 3-year-old child?
80-140 beats per minute
60-100 beats per minute
100-160 beats per minute
70-120 beats per minute
The normal resting heart rate for a 3-year-old child ranges from about 80 to 140 beats per minute. Pediatric heart rates are higher than adult rates.
A patient's heart rate increases from 80 to 100 bpm over one hour without activity. This trend most likely indicates:
Early sign of patient distress
Onset of bradycardia
Normal diurnal variation
Improved cardiovascular fitness
An unexplained rise in heart rate can be an early indicator of patient distress, such as pain, anxiety, or developing hypovolemia. Monitoring trends is vital for early intervention.
Which element is essential when documenting vital sign measurements?
Preferred meal
Nurse's shoe size
Time of measurement
Patient's clothing color
Accurate documentation must include the time of measurement for vital signs to track trends and correlate changes with clinical events. Other details are not clinically relevant.
Why should an oral temperature not be taken in an unconscious patient?
Ear canal blockage
Risk of aspiration
Low blood sugar interference
Dry mouth error
An unconscious patient cannot safely hold the thermometer, increasing the risk of aspiration or airway obstruction. Alternative sites should be used in such cases.
What does pulse pressure represent?
Average of systolic and diastolic pressures
Difference between systolic and diastolic pressures
Sum of systolic and diastolic pressures
Ratio of systolic to diastolic pressure
Pulse pressure is calculated as systolic pressure minus diastolic pressure. It reflects the force the heart generates each contraction.
Which method is best for measuring oxygen saturation?
Sphygmomanometer
Thermometer
Pulse oximeter
Stethoscope
A pulse oximeter estimates oxygen saturation noninvasively by measuring light absorption through a pulsating vascular bed. Other devices measure different vital signs.
A patient's blood pressure is 90/80 mmHg, resulting in a pulse pressure of 10 mmHg. A narrowed pulse pressure most likely indicates:
Increased vascular resistance
Decreased stroke volume
Arrhythmia
Hypervolemia
A narrow pulse pressure, typically under 25 mmHg, often indicates reduced stroke volume as seen in heart failure or hypovolemia. It reflects diminished blood ejected per beat.
Which statement correctly describes mean arterial pressure (MAP)?
Sum of systolic and diastolic pressures divided by two
Difference between systolic and diastolic pressures
[(Systolic + 2 Ã- Diastolic) ÷ 3] mmHg
Average of systolic and diastolic pressures
Mean arterial pressure is calculated as (systolic + 2 Ã- diastolic)/3 because diastole lasts roughly twice as long as systole. It represents tissue perfusion pressure.
When measuring blood pressure, why is it important to position the cuff at heart level?
To inflate faster
To increase pulse pressure
To minimize hydrostatic pressure errors
To make the patient comfortable
Positioning the cuff at heart level ensures that hydrostatic pressure does not skew readings. A cuff too high or low will under- or overestimate true arterial pressure.
Calculate the shock index (heart rate divided by systolic blood pressure) for a patient with HR 110 bpm and SBP 90 mmHg, and interpret the result.
0.82, indicating normal hemodynamics
0.75, indicating low risk
1.00, indicating stable vital signs
1.22, indicating possible hypovolemia
Shock index is HR/SBP = 110/90 ≈ 1.22. Values above 0.7 suggest compromised perfusion and possible hypovolemia or shock, warranting prompt assessment.
In a patient with suspected sepsis, which pattern of vital sign changes is an early indicator?
Bradycardia, bradypnea, hypothermia
Increased heart rate, increased respiratory rate, low-grade fever
Stable vital signs throughout
Decreased heart rate, increased blood pressure, hyperthermia
Early sepsis often presents with tachycardia, tachypnea, and low-grade fever as the body mounts an inflammatory response. Recognizing this triad aids in early intervention.
