BP Air released too quick - Correct Answer-false reading
Abdominojugular test or reflux - Correct Answer-positive -> JVD
Resting pulse pressure - Correct Answer-40mmHg
Widened pulse pressure - Correct Answer-increased CV risk
Abnormal pulse pressure - Correct Answer-less than 25% of SBP
Common cause of narrow pulse pressure - Correct Answer-drop
in L vent stroke vol
Trauma, narrow pulse pressure - Correct Answer-blood loss,
insuff preload -> reduced cardiac output
Extremely low pulse pressure - Correct Answer-low stroke volume
(HF, shock)

valve stenosis and cardiac tamponade
Vendarsol
,Causes of wide pulse press - Correct Answer-stiffness of major
arteries, aortic regurg, AV malformation, hyperthyroidism, fever,
anemia
ACE inhibitors - Correct Answer-lower pulse pressure
Cushings triad - Correct Answer-High resting pulse pressure with
bradycardia and irregular breathing -> increased intracranial
pressure
High pulse pressure can lead to - Correct Answer-afib
5mg of folate - Correct Answer-> decreased pulse pressure;
reduces artery stiffness and may prevent S HTN
ABI - Correct Answer-ankle brachial index, evaluates upper limb
and lower limb SBP; do not do if patient has absent/dim pulses

heard
S4 - Correct Answer-late active phase of ventricular filling and are
caused by atrial systole
S1 - Correct Answer-AV valves closing (mitral and tricuspid);
phase of "isovolumetric" contraction where tension is increasing
in the muscles but without shortening of muscle fibers; signifies
onset of ventricular systole; LV depolarizes and contracts slightly
before RV (may hear split M1 -> T1)
