Pathophysiology Final Exam | Questions & Answers
with Rationales | 2026 Study Guide
1. What is the link between major depression and cortisol secretion?
A. Elevated cortisol levels directly cause depression
B. Persistently elevated plasma cortisol levels can result in inflammation
that is believed to trigger depression
C. Low cortisol levels are associated with depressive symptoms
D. Cortisol has no effect on depression
Answer: B
Rationale: Individuals with depression often show persistently elevated
plasma cortisol levels due to hypothalamic-pituitary-adrenal (HPA) axis
dysfunction. This chronic hypercortisolism leads to inflammation, which is
believed to trigger or worsen depression. This is part of the
neuroinflammatory hypothesis of depression. The relationship is complex
and not simply direct causation.
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
B. Vitamin B12
,C. Erythropoietin
D. Folic acid
Answer: C
Rationale: The kidneys produce erythropoietin (EPO), which stimulates red
blood cell production in the bone marrow. In chronic renal failure, the
kidneys cannot produce adequate EPO, leading to anemia. Treatment
involves administering recombinant erythropoietin to stimulate RBC
production. Iron, B12, and folic acid may also be needed but are not the
primary deficiency in this case.
3. What is the first indication of nephrotic syndrome in children?
A. Hypertension
B. Hematuria
C. Periorbital edema
D. Proteinuria
Answer: C
Rationale: Periorbital edema (swelling around the eyes) is often the first
noticeable sign of nephrotic syndrome in children. This occurs due to fluid
shifts caused by hypoalbuminemia and decreased oncotic pressure. The
edema is typically worse in the morning and may improve during the day.
Proteinuria is the hallmark but is not visible.
4. A patient is in the Emergency Department with heat stroke. What
finding does the healthcare provider associate with this condition?
, A. Excessive sweating
B. Absence of sweating despite a high core temperature
C. Flushed, moist skin
D. Bradycardia
Answer: B
Rationale: Heat stroke is a life-threatening condition characterized by a
core temperature > 40°C (104°F) and anhidrosis (absence of sweating)
despite the high temperature. The thermoregulatory mechanism fails, and
the skin becomes hot and dry. This is a critical distinction from heat
exhaustion, where sweating is still present.
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. Polycystic ovary syndrome
C. Abnormal uterine bleeding
D. Uterine fibroids
Answer: C
Rationale: Abnormal uterine bleeding (AUB) is characterized by irregular or
heavy menstrual bleeding, passage of large clots, and iron deficiency
anemia from chronic blood loss. This is a broad diagnosis that includes
menorrhagia, metrorrhagia, and menometrorrhagia. The other conditions
may cause bleeding but do not encompass all of these manifestations.
