Latest Version with All Questions from Actual Exam
1. What is the link between major depression and cortisol secretion?
A. Decreased cortisol levels lead to inflammation
B. Persistently elevated plasma cortisol levels result in inflammation that triggers depression
C. Cortisol has no effect on depression
D. Low cortisol causes depressive symptoms
Correct Answer: B
Rationale: Individuals with depression exhibit persistently elevated plasma cortisol levels, which
can result in inflammation believed to trigger depression, as per neuroendocrine
pathophysiology.
2. A patient has chronic anemia associated with chronic renal failure. What substance does the
healthcare professional tell the patient is needed to treat this anemia?
A. Iron supplements
B. Erythropoietin
C. Vitamin B12
D. Folic acid
Correct Answer: B
Rationale: Chronic renal failure leads to decreased erythropoietin production by the kidneys,
necessitating exogenous erythropoietin to stimulate red blood cell production.
3. What is the first indication of nephrotic syndrome in children?
A. Hematuria
B. Periorbital edema
C. Proteinuria
D. Hypertension
Correct Answer: B
Rationale: Periorbital edema is often the initial sign of nephrotic syndrome in children due to
hypoalbuminemia and fluid retention from massive proteinuria.
4. A patient is in the Emergency Department with heat stroke. What finding does the healthcare
provider associate with this condition?
A. Profuse sweating
B. Absence of sweating despite a high core temperature
C. Hypotension only
D. Normal mental status
Correct Answer: B
Rationale: Heat stroke involves failure of thermoregulation, leading to absence of sweating
despite elevated core temperature, resulting in hyperthermia.
5. Clinical manifestations that include irregular or heavy bleeding, the passage of large clots, and
the depletion of iron stores support which diagnosis?
A. Endometriosis
B. Abnormal uterine bleeding
C. Polycystic ovary syndrome
,D. Uterine fibroids
Correct Answer: B
Rationale: Abnormal uterine bleeding is characterized by irregular or heavy menstrual bleeding,
clot passage, and iron depletion due to chronic blood loss.
6. The health care professional is caring for a person who has a pathologic fracture. The patient
asks the professional to explain the condition. What response by the professional is best?
A. A fracture due to trauma
B. A fracture at the site of an abnormality already in that bone
C. A stress fracture from overuse
D. A greenstick fracture
Correct Answer: B
Rationale: Pathologic fractures occur at sites of weakened bone due to underlying disease, such
as metastasis or osteoporosis.
7. A patient has a temporary displacement of two bones in a joint causing the bone surfaces to
partially lose contact with each other. What treatment does the health care professional prepare
the patient for?
A. Surgery
B. Reduction and immobilization
C. Physical therapy only
D. Analgesics
Correct Answer: B
Rationale: Subluxation (partial dislocation) requires reduction to realign the joint and
immobilization to allow healing.
8. Cystic fibrosis is characterized by which symptom?
A. Excessive mucus production
B. Pancreatic insufficiency only
C. Lung infections only
D. Genetic mutation without symptoms
Correct Answer: A
Rationale: Cystic fibrosis involves defective CFTR protein leading to excessive mucus
production in respiratory and GI tracts.
9. What is the definition of stroke volume (SV)?
A. Amount of blood ejected per heartbeat
B. Pressure in the arteries during systole
C. Total blood volume in the body
D. Heart rate per minute
Correct Answer: A
Rationale: Stroke volume is the amount of blood ejected from a ventricle in one contraction, key
to cardiac output calculation (SV x HR).
10. What is the definition of multiple sclerosis (MS)?
A. Autoimmune disease with demyelination of nerve fibers
B. Viral infection of the brain
C. Degenerative joint disease
D. Muscle weakness from toxin
Correct Answer: A
Rationale: MS is a central nervous system disease characterized by demyelination, leading to
, episodes of neurologic dysfunction and remission.
11. What is the definition of transient ischemic attack (TIA)?
A. Permanent brain damage from ischemia
B. Minor stroke with quick recovery of neurological function
C. Heart attack
D. Pulmonary embolism
Correct Answer: B
Rationale: TIA is a brief episode of neurological dysfunction due to temporary ischemia, with
full recovery, often a precursor to stroke.
12. What is the definition of myasthenia gravis?
A. Autoimmune neuromuscular disorder with muscle weakness
B. Inflammatory joint disease
C. Bone density loss
D. Skin rash from allergy
Correct Answer: A
Rationale: Myasthenia gravis involves autoantibodies against acetylcholine receptors, causing
voluntary muscle weakness.
13. What is the definition of headaches?
A. Pain in the cranial cavity
B. Visual disturbance only
C. Nausea without pain
D. Seizure activity
Correct Answer: A
Rationale: Headaches (cephalalgia) are pain anywhere in the cranial cavity, with various
etiologies like tension, migraine, or cluster.
14. A woman diagnosed with trichomoniasis asks if her sexual partner should be treated as well.
What is the appropriate response by the healthcare professional?
A. Only if symptomatic
B. Sexual partners should be treated even if asymptomatic
C. No treatment needed for partners
D. Only female partners need treatment
Correct Answer: B
Rationale: Trichomoniasis is a sexually transmitted infection, and treating asymptomatic partners
prevents reinfection and transmission.
15. An infant is brought to the emergency department by parents who report that the baby's
fontanels seem to be bulging outward. What action by the healthcare provider is most
appropriate?
A. Monitor for 24 hours
B. Prepare the baby for a lumbar puncture and blood cultures
C. Administer antibiotics orally
D. Check for allergies
Correct Answer: B
Rationale: Bulging fontanels in infants suggest increased intracranial pressure, often from
meningitis, requiring immediate LP and blood cultures for diagnosis.
16. A patient has polycythemia vera and presents to the Emergency Department with plethora
and neurological changes. The student asks the healthcare professional to explain the primary
