Objective Assessment Exam Questions & Answers |
Latest Updated Review
Master the WGU D236 Pathophysiology Objective Assessment (OA) with this comprehensive study guide
featuring high-yield concepts, detailed explanations, and exam-focused review materials. This updated
resource covers key topics including cellular injury, inflammation, fluid and electrolyte balance, acid-base
disorders, cardiovascular, respiratory, endocrine, renal, and immune system pathophysiology. Designed
to help students strengthen clinical reasoning and confidently prepare for the D236 OA exam, this guide is
ideal for practice, revision, and boosting exam readiness.
uses extreme cold to destroy abnormal or diseased tissue, such
as tumors or damaged nerves
TREATMENT FOR PROSTATE CANCER
cryoablation
,lung disease caused by a long term inhalation of silica dust which
leads to lung inflammation, scarring, and breathing difficulties.
GUY WITH SANDBLASTER
silicosis
damages motor neurons which control voluntary muscle
movements
Amyotrophic lateral sclerosis (ALS)
INVOLUNTARY MUSCLE CONTRACTIONS, WEAKNESS, LOWER
EXTREMITY TWITCHING AND.
PRESCRIBED ANTI GLUTAMATE
Amyotrophic lateral sclerosis (ALS)
most common form of ALS that occurs randomly without a known
genetic
cause or family history
SPORADIC ALS
A 60-year-old man presents with progressive muscle weakness.
He reports difficulty walking, muscle twitching, and recent
trouble swallowing. On exam, he has both upper motor neuron
signs (e.g., hyperreflexia, spasticity) and lower motor neuron
signs (e.g., muscle atrophy, fasciculations). Sensation remains
intact.
Amyotrophic lateral sclerosis (ALS)
chronic degenerative joint disease that occurs when cartilage that
cushions the end of bones gradually wears down over time.
,osteoarthritis
(associated with Osteoarthritis instead of RA)
Enlargement and bulging of a joint contour, commonly described
as swelling, are attributed to the thickening of the subchondral
bone from the proliferation of osteophytes around the margins of
the joint and hypertrophy in the joint capsule.
Bouchard nodes
and
Heberden nodes
A 68-year-old woman complains of chronic knee pain that
worsens with activity and improves with rest. On examination,
there is bony enlargement of the distal interphalangeal joints
(Heberden's nodes) and crepitus in the knees. There is no warmth
or significant swelling.
osteoarthritis
chronic autoimmune disease where the immune system
mistakenly attacks the synovium causing inflammation, pain, and
joint damage.
rheumatoid arthritis
A 45-year-old woman presents with joint pain and stiffness in her
hands and wrists. She reports the stiffness is worst in
the morning and lasts for over an hour. On exam, there
is swelling, tenderness, and limited range of motion in
the metacarpophalangeal (MCP) and proximal interphalangeal
, (PIP) joints bilaterally. Lab results show positive rheumatoid
factor (RF) and anti-CCP antibodies.
rheumatoid arthritis
an infection or inflammation of the inner lining of the heart
affecting the heart valves.
it is caused by bacteria, fungi, or other germs (tooth decay)
**Night sweats
***loud heart murmur
VEGETATION SHOWN ON AN ECHO
ENDOCARDITIS
A 35-year-old man with a history of intravenous drug use
presents with fever, chills, and fatigue. On exam, he has a new
systolic murmur and small, painless lesions on the palms and
soles (Janeway lesions). Blood cultures are positive
for Staphylococcus aureus.
ENDOCARDITIS
NECK/JAW PAIN
CHEST PAIN (angina pectoris)
VOMITING
DIAGNOSIS
**LACK OF O2=death to muscle tissue (necrosis)
**OCCLUSION OF CORONARY ATERY
MI (myocardial infarction)
