CCRN Review Laura Gasparis2025 questions and answers
Malignant HTN - answer Diastolic >140 mm Hg *
and is associated with retinal hemorrhages and
papilledema
Hypertrophic Cardiomyopathy (HCM) or HOCM or
IHSS - answer Big septum that hangs out in L
ventricle. Only fills up with 30 cc instead of 70 cc
(decrease in cardiac output)
Increased thickening of heart muscle (SEPTUM)
ventricles become rigid and stiff
Digoxin, morphine, dopamine and nitrates are
contraindicated (you don't want anything that
vasodilates) You want to give beta blocker or
calcium channel blocker. You want the heart to be
in diastole longer. (Fills up 35 cc instead and it will
squeeze out a really long time)
Pulmonary artery pressure - answer Systolic (PAS)
(R V in systole squeezing blood into PA) Elevated in
lung problems such as pulm HTN, COPD, ARDS, PE,
hypoxia.
, Diastolic (PAD) (R V is filling) Mitral valve open, tip
of catheter looks at LV. Closely corresponds to
LVEDP. (pressure in ventricles at end of diastole)
Elevated with heart problems.
PA systolic normal - answer 15-25 mmHg
PA diastolic normal - answer 8-10 mm Hg
The PAD does not always reflect the LVEDP ** -
answer Usually but not always.
RBBB (hindrance in RV systole creates a drop in
pressure = inaccurate PAD)
Mitral valve disease (cause inaccurate increased
pressure in L atrium due to valve issue)
Pulmonary HTN
Decreased L ventricular compliance
Aortic insufficiency (valve open, blood backflow,
increase in pressure)
Pulmonic insufficiency (valve open, blood backflow,
drop in pressure) - answer You cannot use Swan-
