When you are using the auscultatory method for determining blood pressure, how high do you pump up the pressure in the cuff?
20-30 mmHg above the expected systolic blood pressure

When we take a subject's blood pressure by inflating a blood pressure cuff and feeling for their radial pulse, we call this the ___________________________ method for determining blood pressure.
indirect-palpatory
Which of the following is/are true about the second heart sound?
it occurs when the pressure in the ventricles falls below the pressure in the aorta
When we use a stethoscope and blood pressure cuff to determine blood pressure, we place the diaphragm of the stethoscope where?
medial antecubital fossa
Which heart sound is associated with closing of the semilunar valves?
second
Our body is a little like Goldilocks; it wants everything just right. Which of the following is/are true about hypertension, normotension, and hypotension?
severe hypotension may be a more immediate threat to a pateint's life than hypertension hypertension increases the risk of having a stroke 40-50% of all US adults have hypertension a blood pressure of 80 over 40 could cause syncope
If observed, when does the 4th heart sound occur relative to our other heart sounds?
shortly before S1
When we talk about a patient's blood pressure, if we do not say otherwise we are referring to pressure in what part of the circulatory system?
systemic arterial presssure at the level of the heart
One of your patients has hypertension and you usually determine that their blood pressure is around 154/90. However, one of your interns usually determines that they have a blood pressure of around 128/90. What might they be doing wrong to get this answer?
they might not be pumping the pressure in the cuff high enough to be able to observe the first Korotkoff sound
When we use the auscultatory method for determining blood pressure:
we are listening for Korotkoff sounds
