Prep | Graded A+
1. In a laboratory test, if a patient’s blood shows no antigens and no antibodies,
what might this suggest about their immune status?
The patient may not have been exposed to any pathogens.
The patient has a strong immune response.
The patient is currently infected with a virus.
The patient is likely suffering from an autoimmune disorder.
2. Describe the significance of the imbalance of cytokines in children with cystic
fibrosis, particularly focusing on IL-10 and TNF-α.
A deficit of IL-10 indicates a stronger immune response in cystic
fibrosis.
Excess IL-4 and IL-12 are beneficial for children with cystic fibrosis.
The cytokine levels have no significant impact on the health of
children with cystic fibrosis.
The imbalance of cytokines, including a deficit of IL-10 and an
excess of TNF-α, can lead to increased inflammation and impaired
immune response in children with cystic fibrosis.
3. Which of the following congenital heart defects manifests as loud systolic
murmurs, thrills, and wide pulse pressures?
Coarctation of the aorta (CoA)
Patent ductus arteriosus (PDA)
Ventricular septal defect (VSD)
, Tetralogy of Fallot (ToF)
4. What is the definition of hypersensitivity in immunology?
Disturbance in the immunologic tolerance of selfantigens
Immunologic reaction of one person to the tissue of another person
Undetectable immune response in the presence of antigens
Altered immunologic response to an antigen that results in disease
5. A 1-year-old female is diagnosed with anemia secondary to insufficient
erythropoiesis. The most likely cause is:
A hemoglobin abnormality
An erythrocyte structural abnormality
Genetic factors
An iron deficiency
6. In stage II cancer, the cancer _.
is still contained in the original tumor
has spread to nearby lymph nodes
has returned after being treated
is well-developed and has spread to other tissues or organs
7. These are located at the base of the aorta behind the semilunar valves:
Lunula
Coronary arteries
Coronary ostia
Aortic sinuses
,8. The antibody is responsible for immediate (type I) hypersensitivity
reactions.
IgE
IgA
IgD
IgG
9. If a patient has low hemoglobin levels, what impact would this have on
oxygen transport in their body?
Enhanced oxygen transport efficiency
Increased oxygen transport
Reduced oxygen transport
Normal oxygen transport
10. If a patient is diagnosed with a stage 2 tumor, what implications does this
have for their prognosis compared to a stage 1 tumor?
The prognosis for a stage 2 tumor is worse than for a stage 3 tumor,
indicating a less severe condition.
The prognosis may be less favorable for a stage 2 tumor due to its
local invasiveness, indicating a more advanced disease.
The prognosis for a stage 2 tumor is generally better than for a stage
1 tumor due to earlier detection.
The prognosis for a stage 2 tumor is the same as for a stage 1 tumor,
as both are localized.
11. Which type of cancer is specifically mentioned as being potentially reduced
by exercise according to research?
, Endometrial
Colon
Liver
Stomach
12. In which primary immune deficient disease does the patient don't have
enough T cells?
DiGeorge syndrome
Hyper IgM syndrome
Isolated IgA deficiency
AIDS
13. For Gonorrhea, what is the most common site of infection for men?
urethra
rectum
thorat
eyes
14. Which of the following accurately describes DiGeorge syndrome?
Combined T cell and B cell deficiency
T cell deficiency from undeveloped thymus
Adenosine deaminase deficiency
Failure of B cell precursors to mature into B cells
15. Hypersensitivity refers to:
A normal immune response to pathogens.
