1. A patient with systemic lupus erythematosus (SLE) develops fatigue,
joint pain, and a butterfly-shaped rash on the face. Which
pathophysiologic mechanism is primarily responsible for this disease?
A. Bacterial invasion of connective tissue
B. Autoimmune-mediated tissue destruction
C. Excessive production of red blood cells
D. Deficiency of immunoglobulin production
Answer: B. Autoimmune-mediated tissue destruction
Systemic lupus erythematosus is an autoimmune disorder in which the
immune system produces antibodies against self-antigens. These
immune complexes deposit in tissues and cause inflammation and
damage affecting multiple organs, including the skin, joints, kidneys,
and cardiovascular system.
2. A patient with chronic kidney disease develops anemia. Which
mechanism best explains this finding?
,A. Increased destruction of platelets
B. Reduced erythropoietin production by the kidneys
C. Excessive iron absorption
D. Increased production of white blood cells
Answer: B. Reduced erythropoietin production by the kidneys
The kidneys normally produce erythropoietin, a hormone that
stimulates red blood cell production in the bone marrow. In chronic
kidney disease, decreased erythropoietin levels result in reduced
erythrocyte production and anemia.
3. A patient with heart failure experiences shortness of breath and
pulmonary crackles. Which process contributes most directly to these
findings?
A. Decreased blood volume
B. Pulmonary fluid accumulation from increased cardiac pressures
C. Increased airway resistance from asthma
D. Reduced production of surfactant
Answer: B. Pulmonary fluid accumulation from increased cardiac
pressures
,Heart failure reduces the heart’s ability to pump effectively, causing
blood to back up into the pulmonary circulation. Increased hydrostatic
pressure forces fluid into the alveoli, producing pulmonary congestion,
crackles, and dyspnea.
4. Which inflammatory mediator plays a major role in producing fever
during systemic infection?
A. Insulin
B. Prostaglandin E2
C. Thyroxine
D. Erythropoietin
Answer: B. Prostaglandin E2
During infection, cytokines stimulate the hypothalamus to increase
prostaglandin E2 production. This raises the body’s temperature set
point, resulting in fever as part of the immune response.
5. A patient develops septic shock after a severe infection. Which
physiologic change is expected?
A. Increased systemic vascular resistance
, B. Decreased inflammatory response
C. Widespread vasodilation and impaired tissue perfusion
D. Increased oxygen delivery to tissues
Answer: C. Widespread vasodilation and impaired tissue perfusion
Septic shock occurs when an exaggerated immune response causes
systemic inflammation, vasodilation, capillary leakage, and poor tissue
oxygenation. These changes can lead to organ dysfunction and failure.
6. Which laboratory finding is most consistent with acute
inflammation?
A. Decreased C-reactive protein level
B. Elevated C-reactive protein level
C. Reduced white blood cell activity
D. Decreased cytokine production
Answer: B. Elevated C-reactive protein level
C-reactive protein is an acute-phase reactant produced by the liver
during inflammation. Elevated levels indicate an active inflammatory
process and are commonly monitored in infectious and inflammatory
diseases.
