What is the normal adult oral temperature range in degrees Fahrenheit?
96.8°F to 100.4°F
100.5°F to 104.0°F
90.0°F to 95.0°F
94.0°F to 98.0°F
The typical normal adult oral temperature is between 96.8°F and 100.4°F. Outside this range, hypothermia or fever may be present. Consistent measurement site and technique improve accuracy.
Which pulse site is located at the wrist on the thumb side?
Radial
Carotid
Ulnar
Brachial
The radial pulse is palpated on the lateral wrist (thumb side) and is commonly used for routine assessments. Using the pads of your index and middle fingers, avoid using the thumb to prevent detecting your own pulse.
What is the normal resting heart rate range for a healthy adult in beats per minute?
100 to 120 bpm
60 to 100 bpm
30 to 50 bpm
40 to 60 bpm
A normal resting adult heart rate ranges from 60 to 100 beats per minute. Rates below 60 indicate bradycardia, while rates above 100 indicate tachycardia at rest. Factors like fitness level, medications, and temperature can influence heart rate.
What is the typical normal respiratory rate for an adult at rest?
6 to 10 breaths per minute
20 to 30 breaths per minute
30 to 40 breaths per minute
12 to 20 breaths per minute
Adults usually have a resting respiratory rate of 12 to 20 breaths per minute. Rates below this may indicate respiratory depression, and rates above may suggest distress or compensation. Always observe respirations unobtrusively for accuracy.
Which unit is used to measure blood pressure?
Millimeters of mercury (mmHg)
Pascal (Pa)
Atmospheres (atm)
Centimeters of water (cmH?O)
Blood pressure is conventionally measured in millimeters of mercury (mmHg) using a sphygmomanometer. This unit reflects the pressure required to displace a column of mercury. Standardized units ensure consistency in clinical practice.
Which of the following is often considered the 'fifth vital sign' in many healthcare settings?
Pain level
Blood glucose
Oxygen saturation
Height
Pain is frequently termed the 'fifth vital sign' to emphasize its assessment alongside temperature, pulse, respiration, and blood pressure. It is usually measured on a numeric or visual analogue scale. Regular pain assessment improves patient comfort and outcomes.
A drop in systolic blood pressure of 20 mmHg when a patient moves from lying to standing indicates which condition?
Pseudohypertension
Orthostatic hypotension
Hypertensive crisis
White coat syndrome
Orthostatic hypotension is diagnosed when systolic blood pressure falls by 20 mmHg or more upon standing. It can cause dizziness or syncope. Monitoring positional changes helps identify at-risk patients.
Which of the following can cause a falsely low pulse oximetry reading?
High ambient light
Movement artifact
Low hemoglobin levels
Dark nail polish
Dark nail polish, especially black or blue, can absorb light wavelengths and produce falsely low SpO? readings. Removing polish or using an alternative site like the earlobe can improve accuracy. Motion artifact more commonly causes erroneous high or low readings but is not as specific.
Bradypnea refers to which respiratory pattern?
More than 20 breaths per minute
Periodic cessation of breathing
Fewer than 12 breaths per minute
Deep, rapid breathing
Bradypnea is defined as a respiratory rate of fewer than 12 breaths per minute in adults. It may result from respiratory depression or metabolic disorders. Clinicians should assess level of consciousness and oxygenation.
Tachypnea is identified by a respiratory rate exceeding what value?
12 breaths per minute
10 breaths per minute
30 breaths per minute
20 breaths per minute
Tachypnea occurs when respiratory rate exceeds 20 breaths per minute in adults at rest. It can indicate respiratory distress, pain, fever, or metabolic acidosis. Accurate observation without patient awareness yields the best data.
When measuring blood pressure manually, the stethoscope should be placed over which artery?
Ulnar artery
Brachial artery
Femoral artery
Radial artery
Manual blood pressure measurement requires placing the stethoscope bell or diaphragm over the brachial artery in the antecubital fossa. This allows clear detection of Korotkoff sounds. Placement too distal or proximal can yield inaccurate readings.
If a patient's breathing pattern is irregular, what is the most appropriate way to measure the respiratory rate?
Observe for 10 seconds and multiply by six
Count for 15 seconds and multiply by four
Count for a full minute
Estimate based on pulse rate
When respirations are irregular, counting for a full minute provides the most accurate assessment of rate. Shorter intervals risk misinterpretation of variability. The patient should be unaware of the assessment to avoid altered breathing patterns.
Which temperature reading is typically about 0.5°F higher than an oral measurement?
Temporal
Rectal
Tympanic
Axillary
Rectal temperatures are usually about 0.5°F higher than oral readings, reflecting core body temperature more closely. Axillary is lower, while tympanic and temporal approximate core temperature but can vary with technique. Choosing the proper site is important for accuracy.
Using a blood pressure cuff that is too small for a patient's arm typically results in which error?
Falsely low blood pressure
Falsely high blood pressure
No significant error
Underestimation of pulse pressure
A cuff that is too small requires more pressure to occlude the artery, leading to an overestimation of both systolic and diastolic pressures. Proper cuff size is critical: the bladder width should be about 40% and length 80% of arm circumference.
What is pulse pressure?
Systolic minus diastolic pressure
Diastolic minus systolic pressure
Sum of systolic and diastolic pressure
Average of systolic and diastolic pressure
Pulse pressure is the numerical difference between systolic and diastolic blood pressures. A normal pulse pressure is typically 30 - 40 mmHg. Abnormal values can indicate cardiovascular issues.
Which Korotkoff phase corresponds to the systolic blood pressure?
Phase IV
Phase II
Phase I
Phase V
Korotkoff Phase I is the first appearance of faint, clear tapping sounds and corresponds to the systolic pressure. Subsequent phases represent changes in the quality of sounds until they disappear at diastolic pressure (Phase V).
Which Korotkoff phase is used to determine diastolic pressure in adults?
Phase II
Phase V
Phase IV
Phase III
In adults, diastolic pressure is recorded at Korotkoff Phase V, where sounds disappear completely. Phase IV (muffling) may be used in children, but Phase V is standard in most adults.
Cheyne - Stokes respirations are characterized by which pattern?
Random shallow breaths with irregular pauses
Cyclical crescendo-decrescendo breaths followed by periods of apnea
Rapid, shallow breaths without pause
Deep, gasping breaths with prolonged expiration
Cheyne - Stokes respiration is a cyclical pattern of gradually increasing and then decreasing tidal volumes, separated by brief apnea periods. It can occur in heart failure or central nervous system injury. Recognizing the pattern aids clinical assessment.
Which factor can specifically cause a falsely low SpO? reading on a pulse oximeter?
Poor peripheral perfusion
Fever
High hemoglobin levels
Elevated PaCO?
Poor peripheral perfusion, as seen in shock or hypothermia, reduces blood flow to extremities and impairs pulse oximeter signal, causing falsely low readings. Warming the site or using a more central location can improve accuracy.
When using a tympanic thermometer in an adult, how should the examiner position the pinna?
Pull down and forward
Rotate outward
Hold straight without traction
Pull up and back
For accurate tympanic measurements in adults, the pinna is pulled up and back to straighten the ear canal. In children under 3, the pinna is pulled down and back. Proper positioning ensures sensor alignment with the tympanic membrane.
Where is the apical pulse located?
Second intercostal space at the left sternal border
Fourth intercostal space at the left midaxillary line
Third intercostal space at the right sternal border
Fifth intercostal space at the midclavicular line
The apical pulse is best heard at the fifth intercostal space in the midclavicular line (apex of the heart). It provides the most accurate measure of heart rate in irregular rhythms or infants. Counting for a full minute ensures correct rate determination.
Which temperature measurement site provides the most accurate estimate of core body temperature?
Axillary
Temporal
Rectal
Oral
Rectal measurements reflect core body temperature more accurately than oral, axillary, or temporal sites. They are preferred when precise readings are essential, despite being more invasive. Clinical context guides site selection.
In orthostatic vital sign assessment, what sequence is correct?
Supine, standing, sitting
Supine, sitting, standing
Sitting, standing, supine
Standing, supine, sitting
Orthostatic vital signs are taken with the patient supine, then sitting, then standing, usually with a 1 - 3 minute wait between positions. This sequence assesses cardiovascular response to postural change. Consistent technique prevents misinterpretation.
What is an 'auscultatory gap' in blood pressure measurement?
Temporary disappearance of sounds between Phase I and II
Sudden louder sounds after cuff deflation
Absence of sounds until below diastolic pressure
Continuous muffled sounds throughout deflation
An auscultatory gap is a transient silence between the first (Phase I) and second Korotkoff sounds, which can lead to underestimating systolic pressure if unrecognized. Detecting this gap requires careful palpation and auscultation.
A wide pulse pressure is most commonly associated with which condition?
Hypovolemia
Cardiac tamponade
Aortic regurgitation
Heart block
Wide pulse pressure, an increased difference between systolic and diastolic pressure, is characteristic of aortic regurgitation due to rapid runoff of blood from the aorta. Conditions like hypovolemia narrow pulse pressure.
Pulsus paradoxus is defined by which phenomenon?
An inspiratory drop in systolic blood pressure >10 mmHg
A diastolic increase during inspiration
Equal changes in systolic and diastolic pressure
A systolic rise during expiration
Pulsus paradoxus is an exaggerated decrease (>10 mmHg) in systolic pressure during inspiration. It can indicate cardiac tamponade, severe asthma, or COPD. Measuring it requires precise blood pressure monitoring.
Which respiration pattern is characterized by deep, rapid breathing without pauses?
Cheyne - Stokes respirations
Biot respirations
Orthopnea
Kussmaul respirations
Kussmaul respirations are deep, rapid breaths typically associated with metabolic acidosis, such as in diabetic ketoacidosis. They differ from Cheyne - Stokes (cyclical increase and decrease) and Biot (clusters with apnea) patterns.
Biot respirations are identified by which pattern?
Clusters of quick, shallow breaths followed by regular periods of apnea
Rapid, regular breathing
Gradual increase and decrease in tidal volume
Deep, grunting breaths
Biot respirations consist of groups of quick, shallow breaths followed by periods of apnea. They often result from increased intracranial pressure or medullary injury. Recognizing the pattern guides neurological assessment.
Hyperthermia typically increases heart rate by approximately how many beats per minute per 1°C rise in body temperature?
20 beats per minute
30 beats per minute
10 beats per minute
2 beats per minute
For each 1°C increase in body temperature, heart rate usually rises by about 10 beats per minute. This relationship, called Liebermeister's rule, reflects increased metabolic demand. Monitoring vitals guides fever management.
What percentage of the arm circumference should the blood pressure cuff bladder length cover?
60%
40%
80%
100%
The cuff bladder length should cover at least 80% of the arm circumference to ensure accurate blood pressure readings. If the bladder is too short or too narrow, readings may be falsely elevated. Proper sizing is essential for reliable measurements.
An inter-arm blood pressure difference greater than 10 mmHg may suggest which condition?
Aortic regurgitation
Pericarditis
Subclavian artery stenosis
Mitral valve prolapse
A difference in systolic blood pressure of more than 10 mmHg between arms may indicate subclavian artery stenosis or other vascular obstruction. Bilateral readings help detect peripheral arterial disease.
When a patient's arm circumference exceeds the range of an adult cuff, what is the next best action?
Apply two adult cuffs in tandem
Use a pediatric cuff
Use a thigh cuff on the arm
Estimate pressure by palpation only
If an adult cuff cannot properly encircle a large arm, using a thigh cuff (which has a larger bladder) on the upper arm provides accurate readings. Pediatric cuffs are too small, and tandem adult cuffs are not recommended.
Pulsus alternans is a vital sign irregularity indicating what underlying issue?
Pulmonary embolism
Mitral stenosis
Right atrial enlargement
Left ventricular dysfunction
Pulsus alternans, characterized by alternating strong and weak pulses, is associated with left ventricular dysfunction and heart failure. It reflects impaired myocardial contractility. Identification requires careful palpation or arterial waveform analysis.
What is the normal capillary refill time in adults?
Less than 2 seconds
2 to 4 seconds
More than 6 seconds
4 to 6 seconds
Normal capillary refill time is under 2 seconds when pressing on a fingernail or skin. Longer refill times can indicate poor perfusion or shock. Conditions like cold environment can also extend refill time.
Which scenario may produce a falsely normal SpO? reading despite inadequate oxygen delivery?
Hypovolemia
Carbon monoxide poisoning
Anemia
Peripheral edema
Carbon monoxide binds hemoglobin with high affinity, producing carboxyhemoglobin that a standard pulse oximeter reads as oxyhemoglobin, resulting in falsely normal SpO?. Co-oximetry is required for accurate assessment.
What is the most widely accepted formula for calculating mean arterial pressure (MAP)?
Systolic pressure × diastolic pressure divided by two
(Systolic + diastolic) ÷ 2
Systolic pressure ? diastolic pressure
Diastolic pressure + one-third pulse pressure
MAP is commonly estimated as diastolic pressure plus one-third of the pulse pressure (systolic minus diastolic). This reflects the average arterial pressure driving blood flow during the cardiac cycle. Accurate MAP helps guide perfusion management.
Pulsus bisferiens, a double-peaked arterial pulse, is classically associated with which condition?
Mitral regurgitation
Cardiac tamponade
Pulmonary hypertension
Combined aortic stenosis and regurgitation
Pulsus bisferiens features two systolic peaks per cardiac cycle and is most classically seen in combined aortic stenosis and regurgitation. It reflects the biphasic ventricular ejection patterns. Detailed hemodynamic assessment confirms diagnosis.
Circadian variations in body temperature are primarily regulated by which physiological mechanism?
Thyroid hormone fluctuations hourly
Peripheral vasoconstriction peripherally
Hypothalamic thermoregulatory set point influenced by melatonin and cortisol
Renal excretion of heat
Circadian temperature rhythms are governed mainly by the hypothalamic thermoregulatory set point, which is influenced by hormones like melatonin and cortisol. This leads to lower evening and higher afternoon temperatures. Disruptions can impact patient assessment.
Which cytokines are most directly involved in raising the hypothalamic set point during infection-related fever?
Transforming growth factor-beta and interleukin-8
Interleukin-1 and tumor necrosis factor-alpha
Interferon-gamma and interleukin-2
Interleukin-4 and interleukin-10
During infection, pyrogenic cytokines such as interleukin-1 and tumor necrosis factor-alpha act on the hypothalamus to raise the temperature set point, causing fever. Anti-inflammatory cytokines (e.g., IL-10) counteract this effect.

Cheat Sheet

  1. Accurate Temperature Measurement -

    Place the thermometer correctly (oral, tympanic or rectal) and wait for its full reading cycle to prevent errors. Normal adult temperature ranges from 36.1°C to 37.2°C (97°F to 99°F); deviations may indicate infection or hypothermia. Use the mnemonic "TORE" (Tympanic, Oral, Rectal, External canal) to recall sites and precautions per WHO guidelines.

  2. Pulse Assessment Techniques -

    Evaluate rate, rhythm and strength by palpating the radial or apical pulse for a full 60 seconds; normal adult rate is 60 - 100 bpm (American Heart Association). Note irregularities like arrhythmias and document findings immediately, a best practice highlighted in vital signs quiz prep resources. Practicing with a stethoscope and stopwatch builds confidence for the RN vital signs assessment 2.0.

  3. Respiratory Rate Monitoring -

    Count respirations unobtrusively for 30 seconds (multiply by two) to gauge rate, depth and rhythm; normal adult range is 12 - 20 breaths per minute. Observe chest rise and fall for effort and use of accessory muscles, as recommended by accredited nursing fundamentals texts. Accurate practice vital signs technique reduces observer bias and enhances clinical reliability.

  4. Blood Pressure Evaluation and MAP Calculation -

    Use a correctly sized cuff placed at heart level and listen for Korotkoff sounds to identify systolic and diastolic pressures (AHA standard). Calculate mean arterial pressure (MAP) with MAP = (SBP + 2×DBP) ❄ 3 to assess organ perfusion. Consistent technique is crucial in vitals quiz scenarios and routine fundamentals of nursing vital signs practice questions.

  5. Oxygen Saturation and Perfusion -

    Apply a pulse oximeter probe to a warm, well-perfused finger and aim for SpO2 ≥ 95%; values below 90% signal potential hypoxemia (American Thoracic Society). Remove nail polish and ensure good contact to avoid false readings during your practice vitals quiz simulations. Interpreting SpO2 alongside vital trends boosts clinical judgment in RN vital signs assessment 2.0.
