WGU D027 STUDY GUIDE QUESTIONS
AND ANSWERS WITH VERIFIED
SOLUTIONS 100% CORRECT RATED A+
NEWLY UPDATED 2025
Autosomal Dominant
✔✔ Only one parent needs to carry the gene; there is a 50% chance the child will
inherit the condition.
Autosomal Recessive
✔✔ Both parents must be carriers; there's a 25% chance the child will have the
disorder and a 50% chance the child will be a carrier.
Cystic Fibrosis
✔✔ A genetic disorder that affects the pancreas and leads to thick mucus buildup,
especially in the lungs.
21st Trisomy
✔✔ Also known as Down syndrome, caused by an extra copy of chromosome 21.
Klinefelter Syndrome (XXY)
✔✔ A genetic condition in males with an extra X chromosome, leading to some
female physical traits.
Turner Syndrome
✔✔ A condition in females where one X chromosome is missing or incomplete.
,Alpha Thalassemia
✔✔ An inherited blood disorder that causes varying degrees of anemia, from mild
to life-threatening.
Beta Thalassemia
✔✔ A condition that reduces hemoglobin production; ferrous sulfate is
contraindicated due to risk of iron overload.
Prevalence Risk
✔✔ Refers to the proportion of individuals in a population who have a particular
condition at a specific point in time.
Incidence Rate
✔✔ Measures the number of new cases of a condition in a population over a set
period of time.
Innate immunity - ANSWER✔✔inflammation; increased vascular permeability
B&T lymphocytes - ANSWER✔✔immune response
primary malignant tumor - ANSWER✔✔lack of organization of cells
glucocorticoids - ANSWER✔✔used in combination with other agent to treat
lymphoid tissue (leukemia). glucocorticoids are directly toxic to lymphoid tissues.
Selective estrogen receptor modulators (SERM) - ANSWER✔✔for hormone
receptor positive and advanced breast cancer. (Tamoxifin reduces risk and
recurrence risk)
, Heart failure - ANSWER✔✔impairment of the ventricle to fill with or eject blood;
heart cannot meet metabolic need of the body.
CHF - ANSWER✔✔heart cannot keep up with metabolic needs; volume overload
in pulmonary area
Left Ventricular Dysfunction - ANSWER✔✔reduced ejection fraction; ventricle
having issue ejecting blood.
normal ejection fraction - ANSWER✔✔55 - 60 % (blood pumped out with each
heartbeat)
Ejection fraction of 50% - reduced or preserved? - ANSWER✔✔preserved
Diastolic CHF - ANSWER✔✔preserved ejection fraction, problem is with filling
Systolic CHF - ANSWER✔✔reduced ejection fraction, problem is with ejecting
Left sided CHF - ANSWER✔✔pulmonary (JVD, fluid volume overload, rails, S-3
murmurs) ** #1 cause of Right sided CHF
BNP - ANSWER✔✔gold standard lab test to diagnose CHF
Echocardiogram - ANSWER✔✔Diagnostic tool, evaluates heart structure and
function
