Question:
Pulse
Answer:
Stroke volume: amount of blood every heart beat pumps into aorta
About 70 mL in adult Force flares arterial walls and generates pressure wave, felt in periphery as pulse Palpating peripheral pulse gives rate and rhythm of heartbeat, as well as local data on condition of artery Radial pulse usually palpated while vital signs measured Using pads of the first three fingers, palpate radial pulse at flexor aspect of wrist laterally along radius bone If rhythm is regular, count number of beats in 30 seconds and multiply by 2 The 30-second interval is most accurate and efficient when heart rates are normal or rapid and when rhythms are regular

Question:
Assess pulse as following
Answer:
Rate Rhythm Force Elasticity
Question:
Heart Rate
Answer:
In resting adult, normal heart rate range is 60 to 100 beats per minute (bpm) Rate normally varies with age and is more rapid in infancy and childhood and moderate during adult and older years Rate also varies with gender; after puberty, females have slightly faster rate than males In adult, a heart rate less than 60 bpm is bradycardia This occurs normally in well-trained athletes whose heart muscle develops along with skeletal muscles Stronger, more efficient heart muscle pushes out a larger stroke volume with each beat, thus requiring fewer beats per minute to maintain a stable cardiac output A more rapid heart rate, over 100 bpm, is tachycardia Occurs normally with anxiety or with increased exercise to match body's demand for increased metabolism 2 / 3
Question:
Heart Rhythm
Answer:
Rhythm of pulse normally has an even tempo
Sinus arrhythmia: one irregularity commonly found in children and young
adults Here heart rate varies with respiratory cycle, speeding up at peak of inspiration and slowing to normal with expiration Inspiration momentarily causes a decreased stroke volume from left side of heart To compensate, heart rate increases If any other irregularities are felt, auscultate heart sounds for a more complete assessment
Question:
Strength of pulse
Answer:
Weak, thready pulse reflects a decreased stroke volume (e.g., as occurs with hemorrhagic shock) Full, bounding pulse denotes increased stroke volume, as with anxiety, exercise, and some abnormal conditions Pulse force recorded using three-point scale 3+ Full, bounding 2+ Normal 1+ Weak, thready
