1. Which of the following is characteristic of chronic transplant
rejection?
Choose matching definition
- it involves humoral immunity
- involves increased t lymphocytes
,- can not occur months to years after transplant
- it is the active form of vitamin d, converted in the liver
Answer: it involves humoral immunity
Verified Rationale:
Chronic transplant rejection is primarily mediated by humoral (antibody-
mediated) immune responses as well as alloantibody targeting of the graft
vasculature. Over time, this results in progressive vasculopathy and fibrosis of
the transplanted tissue. T lymphocytes can be involved, but the chronic phase
distinctively features antibody-mediated mechanisms. Chronic rejection
develops months to years after transplantation, and is a major cause of late
allograft failure.

2. A decrease in Na+ reabsorption is achieved through the action of which
of the following?
Choose matching definition
- nitrates
- diuretics
- antihistamines
- anticoagulants
Answer: diuretics
, Verified Rationale:
Diuretics are a class of drugs specifically designed to reduce sodium
reabsorption in the renal tubules, resulting in increased excretion of
sodium and water. This pharmacological effect is utilized in treating
hypertension, heart failure, and edema by decreasing fluid volume.

3. Which of the following is/are true regarding acid-base disorders?
(mark all that apply)
Choose matching definition
- Metabolic disorders are a result of a change in plasma HCO3- levels
- Respiratory disorders are a result of a change in plasma CO2 levels
- Normal blood pH = 7.35-7.45
Answer:
- Metabolic disorders are a result of a change in plasma HCO3- levels
- Respiratory disorders are a result of a change in plasma CO2 levels
- Normal blood pH = 7.35-7.45
Verified Rationale:
Acid-base balance is tightly maintained through respiratory control of CO₂ and
renal control of HCO₃⁻ . Disorders involving bicarbonate levels (HCO₃⁻ ) are
classified as metabolic, while those involving CO₂ are classified as respiratory.
Normal arterial blood pH is 7.35-7.45.
