WGU D027 FINAL STUDY GUIDE WITH
DETAILED PRACTICE QUESTIONS AND
VERIFIED SOLUTIONS(A+ GUIDE
SOLUTION) NEWEST 2025/2026
What organ does cystic fibrosis affect? - ANS>> Affects the pancreas
causing secretions into the lungs
What is Klinefelter syndrome? - ANS>> An extra X chromosome for males
so example XXY causing female-like qualities
What is Turner Syndrome? - ANS>> females. missing or deformed x
chromosome. right hemisphere dysfunction, hearing loss, ear infection,
language and articulation disorders, visual spatial and attentional problems
What is beta thalassemia? - ANS>> a condition in which the synthesis of
the beta-globin chains is decreased or absent. Causes low hemoglobin.
Which medication is contraindicated in a patient with Beta Thalassemia? -
ANS>> Ferrous Sulfate
What drug is used in combination with other agent to treat lymphoid tissue
(leukemia). Directly toxic to lymphoid tissues Selective estrogen receptor
modulators (SERM) - for hormone receptor positive and advanced breast
cancer. (Tomaxafin - reduces risk and recurrence risk) - ANS>>
Glucocorticoids
What is the normal ejection fraction? - ANS>> 55-60%. Less than 50% is
BAD
Is an ejection fraction of 50% reduced or preserved? - ANS>> Preserved
What are symptoms of left sided heart failure? - ANS>> Think
PULMONARY. JVD, FVO, rails, S3 murmurs. Number one cause of right
sided heart failure!
, What should you assess before giving Digoxin? - ANS>> Apical pulse
How should Warfarin be started? - ANS>> Start initial dose at half to
monitor the effects
What causes the destruction of alveolar walls? Air goes in but can't get out
which leads to hyperinflation - ANS>> Emphysema
What causes excess mucus production and smooth muscle hypertrophy? -
ANS>> Bronchitis
What is a chronic inflammatory obstruction of bronchi? - ANS>> Asthma,
Triggers cause mucus to clog bronchial tubes.
What causes an overbite and buffalo hump? - ANS>> Endocrine disorder
called acromegaly (overproduction of growth hormone)
What causes Addison's disease? - ANS>> Decreased glucocorticoid (due
to autoimmune destruction of adrenal cortex)
What are symptoms of right sided heart failure? - ANS>> Think peripheral
vascular. Lower extremity edema, abdominal distension.
What is the gold standard lab test for heart failure? - ANS>> BNP. Heart
failure is a result greater than 100
What heart disease is worse with exertion? - ANS>> Ischemic heart
disease because the demand requirements are higher.
What causes Cushing's syndrome? - ANS>> excess cortisol
What causes Grave's disease? - ANS>> overproduction of thyroid
hormone. HYPERthyroidism.
When should you instruct the patient to take their FIRST dose of
antihypertensive? - ANS>> At night to avoid orthostatic hypotension.
Educate slow position changes and lay down if needed.
What are side effects of ACE inhibitors? - ANS>> dry cough
