QUESTIONS & VERIFIED ANSWERS
PASSED ALREADY GRADED A+
Autosomal Dominant - correct answer ✔✔1 parent has, 50% change of child having
Autosomal Recessive - correct answer ✔✔Both parents are carriers, 25% change of child having,
50% chance child is a carrier.
Cystic Fibrosis - correct answer ✔✔affects pancreas causing secretions in lungs
21st Trisomy - correct answer ✔✔Down Syndrome
Klinefelter Syndrome (XXY) - correct answer ✔✔male has extra X, female like qualities
Turner Syndrome - correct answer ✔✔Missing X in females
Alpha Thalassemia - correct answer ✔✔inherited blood disorder; mild to severe anemia
Beta Thallasemia - correct answer ✔✔low hemoglobin; contraindicated medication ferrous
sulfate
Prevalence Risk - correct answer ✔✔proportion of the population affected at a certain time
Incidence rate - correct answer ✔✔number of new cases divided by population
,Innate immunity - correct answer ✔✔inflammation; increased vascular permeability
B&T lymphocytes - correct answer ✔✔immune response
primary malignant tumor - correct answer ✔✔lack of organization of cells
glucocorticoids - correct answer ✔✔used in combination with other agent to treat lymphoid
tissue (leukemia). glucocorticoids are directly toxic to lymphoid tissues.
Selective estrogen receptor modulators (SERM) - correct answer ✔✔for hormone receptor
positive and advanced breast cancer. (Tamoxifin reduces risk and recurrence risk)
Heart failure - correct answer ✔✔impairment of the ventricle to fill with or eject blood; heart
cannot meet metabolic need of the body.
CHF - correct answer ✔✔heart cannot keep up with metabolic needs; volume overload in
pulmonary area
Left Ventricular Dysfunction - correct answer ✔✔reduced ejection fraction; ventricle having
issue ejecting blood.
normal ejection fraction - correct answer ✔✔55 - 60 % (blood pumped out with each
heartbeat)
Ejection fraction of 50% - reduced or preserved? - correct answer ✔✔preserved
Diastolic CHF - correct answer ✔✔preserved ejection fraction, problem is with filling
, Systolic CHF - correct answer ✔✔reduced ejection fraction, problem is with ejecting
Left sided CHF - correct answer ✔✔pulmonary (JVD, fluid volume overload, rails, S-3 murmurs)
** #1 cause of Right sided CHF
BNP - correct answer ✔✔gold standard lab test to diagnose CHF
Echocardiogram - correct answer ✔✔Diagnostic tool, evaluates heart structure and function
At Risk for HF - Stage A - correct answer ✔✔no structural heart disease or symptoms of heart
failure
Stage A HF co-morbidities - correct answer ✔✔htn, atherosclerotic disease, diabetes, metabolic
syndrome, patients using cardiotoxins with family history
Therapy goals of stage A HF - correct answer ✔✔treat htn, encourage smoking cessation,
encourage regular exercise, treat lipid disorders, discourage alcohol intake/drug use, control
metabolic syndrome
Meds: ACEI or Angiotensin II RB for vascular disease or diabetes (avapro, losartan, benicar,
diovan, etc)
At Risk for HF - Stage B - correct answer ✔✔structural heart disease but no symptoms of heart
failure
Stage B HF co-morbidities - correct answer ✔✔previous MI, LV remodeling with LV hypertrophy
and low EF, asymptomatic valvular disease
