- 1.
The functionof hemoglobin is
- A.
Prevent bleeding
- B.
Carry oxygen into cells
- C.
Fight off infection
- D.
Improve cardiac output
- E.
Assist in prolong vomiting
Correct Answer
B. Carry oxygen into cellsExplanation
Hemoglobin is a protein found in red blood cells that is responsible for carrying oxygen from the lungs to the cells throughout the body. It binds to oxygen in the lungs and releases it in the tissues, ensuring that oxygen is delivered to all the cells for their proper functioning. Therefore, the correct answer is "carry oxygen into cells".Rate this question:

Iron deficiency anemia is caused by
- A.
Inadequate supply of Iron
- B.
Genetics
- C.
Excessive hydration
- D.
Vitamin C reabsorption
Correct Answer
A. Inadequate supply of IronExplanation
Iron deficiency anemia is caused by an inadequate supply of iron. Iron is an essential mineral required for the production of hemoglobin, a protein in red blood cells that carries oxygen throughout the body. When there is a lack of iron in the diet or the body is unable to absorb iron properly, it leads to a decrease in the production of hemoglobin, resulting in iron deficiency anemia. This condition can be caused by various factors such as poor dietary intake, malabsorption disorders, or chronic blood loss.Rate this question:

HIV primarily affects
- A.
Beta cells
- B.
RBC's
- C.
Cardiac output
- D.
CD4 T-lymphocytes
Correct Answer
D. CD4 T-lympHocytesExplanation
HIV primarily affects CD4 T-lymphocytes, which are a type of white blood cells that play a crucial role in the immune system. The virus targets these cells and enters them, using them as a host to replicate and spread throughout the body. As the virus replicates, it destroys CD4 T-lymphocytes, weakening the immune system and making the body more susceptible to infections and diseases. This is why CD4 T-lymphocyte count is used as a measure of the progression of HIV infection and the effectiveness of antiretroviral therapy.Rate this question:

Clinical manifestations of HIV include:
- A.
Increased cardiac output
- B.
Decrease in kidney function
- C.
Pnemocystitis Carinii
- D.
Decrease size in spleen due to lack of blood supply
Correct Answer
C. Pnemocystitis CariniiExplanation
Pneumocystis carinii is a common opportunistic infection seen in individuals with HIV. It is caused by a fungal organism called Pneumocystis jirovecii. This infection primarily affects the lungs and can cause symptoms such as cough, shortness of breath, and fever. It is an important clinical manifestation of HIV because it typically occurs in individuals with a weakened immune system, making it a significant marker of disease progression. The other options listed, such as increased cardiac output, decreased kidney function, and decreased size of the spleen, are not directly associated with HIV infection.Rate this question:

Diagnostics in HIV in children includes a/n
Correct Answer
ELISA
Eastern blot test
CBCExplanation
Diagnostics in HIV in children includes ELISA, Eastern blot test, and CBC. ELISA is a commonly used test to detect HIV antibodies in the blood. The Eastern blot test is a more specific test that helps in confirming the presence of HIV antibodies. CBC (Complete Blood Count) is a routine blood test that provides information about the overall health of the child, including the levels of different blood cells. These three tests are important in diagnosing HIV in children and monitoring the progression of the disease.Rate this question:
