n300 final review
review for n300 final
starts in the skin or in tissues covering internal organs
begins in connective or supportive tissue
begins in bone marrow or blood-producing cells; travels into the bloodflow
lymphoma & myeloma
cancer beginning in the immune system cells
begins in brain or spinal cord
diuretics used for CHF - what should the nurse monitor?
serum potassium levels
inotropic vs chronotropic actions?
inotropic - affects cardiac contraction
chronotropic - affects heart rate
left-sided (aka systolic) heart failure
impaired ventricular contraction (decreased CO)
backup of blood to left atrium, then to lungs
: hacking cough, dyspnea, chest pain
right-sided (aka diastolic) heart failure
due to increased blood volume
ventricles cannot contract to accomodate increased afterload/preload
backward flow to periphery
pulmonary edema often occurs synonmyously with what sided HF?
contraction of the ventricle/atrium
resting period after contraction
trace cardiac conduction through the heart, in order
starts in SA node
travels to AV node
Bundle of His (in the bundle branches)
during cardiac rehab - should the pt be doing isometric or isotonic exercises?
isotonic - gradually increases HR. jogging, etc
isometric - quick increase in HR. requires more oxygen. ie, weight lifting or shoveling snow
mitral valve prolapse?
mitral valve (between LA and LV) is leaky, and blood may seep back into LA from the LV.
: similar to HF, chest pain, palpitations, activity intolerance.
during physical exam
: "mitral click" heard as extra heart sound
mitral valve hardens. causes buildup of fluid in LA b/c blood is not getting to LV
risk of emboli due to pooling blood
right-sided failure will also occur eventually since it is being overworked
symptoms of right-sided HF?
hepatomegaly (enlarged liver)
jugular vein distention
