How to take blood pressure - ANSWER The instrument used is called a
sphygmomanometer. The health care provider uses a blood pressure cuff to cut
, off the blood flow from the brachial artery. As they release the pressure in the
cuff, using a stethoscope, they are listening for the first sound, called the Korotkoff
sound, meaning there is no longer enough pressure to keep all the blood from
flowing. This is the top number or systolic value of the patient's blood pressure.
The provider continues to let air out of the cuff and eventually the sounds
disappear, representing that the brachial artery is now completely open. This is
known as the diastolic value or bottom number in a patient's blood pressure.
Differentiate essential hypertension and secondary hypertension - ANSWER -
Essential hypertension (primary hypertension): cause of the increased blood
pressure is unknown.
-Secondary hypertension: elevated blood pressure is caused by another disease.
peripheral resistance - ANSWER resistance generated by the flow of blood
through the arteries. When this happens, the kidney releases an enzyme called
renin.
Renin enzyme - ANSWER leads to further vasoconstriction, water and sodium
retention, and an increase in blood pressure

supply to the kidney.
