HCC
HCC 2008 Blood Pressure
| Question | Answer |
|---|---|
| blood pressure depends on | force of heartbeat, resistance of the blood vessels, the volume of circulating, viscosity or thickness of the blood |
| maximum pressure is excerted on the walls of the arteries when... | the left ventricle of the heart pushes on the aorta |
| maximum pressure is called | systolic |
| diastolic is | the lowest pressure that occurs btw the contractions of the ventricles or when they are resting |
| systolic pressure is the... | period of ventricular contraction |
| suddenly when listening through the scope the beat of the heart either stops or changes quickly to a dull thud. This number is called the... | diastolic |
| blood pressure | systolic/diastolic |
| sites for assessing blood pressure | upper arm(brachial), upper leg (popliteal), leg (posterior tibial or dorsalis pedis artery) |
| measurement | blood pressure cuff and palpatory method |
| falsely high reading might result from | cuff too narrow, too loose, release cuff too slowly, meniscus not at eye level, bp taken in leg |
| falsely low reading may result from | cuff too wide, arm above heart, miss first round, excessive length of stethoscope, obesity(hard to hear) |
| what would you do if you discovered hypertension? | check baseline, assess surrounding events, reposition patient, check patients meds, length of scope too long, repeat measures |
| what would you do if you discovered hypotension? | rest, position with head lower legs elevated, check pt's activity level |
| significance of pulse pressure | greater than 30-40 it indicates arteries have lost some elasticity |
| auscultatory gap | temporary disappearance of sound, sound of systolic pressure diminishes and returns at lower pressure point |
