#1
Which artery is commonly used for pulse measurement?
Radial artery
ExplanationLocated in the wrist, easily accessible for pulse assessment.
#2
What is the normal resting heart rate for adults?
60-80 beats per minute
ExplanationRepresents the average heartbeats per minute at rest for adults.
#3
Which anatomical site is commonly used to measure a newborn's pulse?
Temporal artery
ExplanationAccessible and reliable site for measuring pulse in infants.
#4
Which age group typically has a higher resting heart rate?
Adolescents
ExplanationYouth generally have faster heart rates compared to adults.
#5
In pulse measurement, what does the term 'bpm' stand for?
Beats per minute
ExplanationUnit used to measure heart rate, indicating the number of heartbeats per minute.
#6
Which factor can affect the accuracy of pulse measurement?
Ambient temperature
ExplanationChanges in temperature can alter blood flow and pulse rate.
#7
Which of the following is the correct method for measuring pulse using the carotid artery?
Place fingers on the neck
ExplanationDirectly assesses pulse by placing fingers gently on the neck, near the windpipe.
#8
What is the term for an unusually fast heart rate, typically exceeding 100 beats per minute?
Tachycardia
ExplanationIndicates rapid heartbeat, potentially requiring medical attention.
#9
What is the term for the pulse felt in the foot, typically near the ankle?
Dorsalis pedis pulse
ExplanationAssesses blood flow to the foot, important in diagnosing vascular conditions.
#10
Which method is commonly used to assess the oxygen saturation level in addition to pulse?
Pulse oximetry
ExplanationMeasures oxygen saturation in blood, alongside pulse rate.
#11
What is the medical term for an elevated heart rate due to fever?
Pyrexia
ExplanationFever-induced increase in heart rate, a response to elevated body temperature.
#12
What is the medical term for an irregular pulse?
Arrhythmia
ExplanationRefers to abnormal heart rhythm, potentially indicating underlying health issues.
#13
What is the primary function of the sinoatrial (SA) node in the heart?
Conduct electrical impulses
ExplanationInitiates electrical signals, coordinating heart contractions.
#14
Which condition is characterized by an absence of pulse in the extremities?
Peripheral artery disease (PAD)
ExplanationSignifies narrowing or blockage of arteries, hindering blood flow.
#15
In pulse measurement, what does a weak and thready pulse suggest?
Dehydration
ExplanationIndicates reduced blood volume, often due to dehydration.
#16
Which position is ideal for measuring blood pressure and pulse simultaneously?
Fowler's position
ExplanationSitting position with knees bent, commonly used in clinical settings for concurrent measurements.
#17
What is the term for an irregular, fluttering heartbeat?
Atrial fibrillation
ExplanationCommon heart rhythm disorder, increasing the risk of complications like stroke.
#18
In pulse measurement, what does the term 'pulsus paradoxus' refer to?
Change in pulse amplitude during respiration
ExplanationNotable decrease in pulse strength during inhalation, indicating cardiac or respiratory issues.
