1. Cathy has just given birth to a little girl. When the nurse tried to feed her or bather her, the baby become cyanotic. Physical examination indicates no structural deformities. Blood gas levels show only 60% saturation with oxygen. What may be causing this problem? A. The infant has malformed digestive system B. the lungs are hyperventilating C. the lungs are hypoventilating D. the cardiovascular supply of the lungs is impaired E. the infant is born with only one lungs 2. The most effective long-term protection against pH changes of body fluid is: A. buffer system of plasma B. Renal control of H+/HCO3- C. Presence of dissolved proteins in the plasma D. Presence of electrolytes in the plasma E. None of the above 3. Jean has been vomiting off & on for a few days due to viral enteritis. His doctor orders SMA7 (seven blood chemistries including electrolytes) the serum will show: A. Low chloride level B. High chloride leve C. Ca++ will be high D. High H+ ions E. Plasma pH will be low 4. The process of invasion by malignant cells is dependent on? A. activation of TNM system B. Release of enzymes by invading cells C. Decreasing anaplasia D. Tissue damage by chemotherapy E. Stromal adesion 5. T- Cells classified as CD8 cells are: A. Cytotoxic T-Cells B. Killers T-cells C. Helper T- cells D. Memory T-cells E. Regulator T-cells 6. Herpes viruses are transmitted to humans by: A. Birds B. Fleas C. Rodents D.Rodents D. Carnivories E. None Solution 1. The correct option is d because the baby becomes cyanotic is mainly because of the insufficient supply of oxygen which is due to the impaired cardiovascular supply of the lungs. 2. the correct option is a because the blood plasma is responsible for the pH maintenance and works with lungs and kidney to maintain the pH of the body fluids by maintaining the acid and base ratio. 3. The correct option is a because the low levels of chloride level suggest that the body is losing the ions away during vomiting along wth the food particles. 4. The correct option is b because the level of enzymes that are released by the invading cells for the destruction of the proteins of the extracellular matrix which separates the cancer cells and the adjoining tissue. The level of degrading enzymes is responsible for the proliferation and escape of the cancer cell into the surrounding tissue. 5. The option is b killer t cells. 6. The correct option is e. because the Herpes viruses are transmitted through skin to skin contact in humans. mainly when in contact with infected person..

Solution
1. The correct option is d because the baby becomes cyanotic is mainly because of the
insufficient supply of oxygen which is due to the impaired cardiovascular supply of the lungs.
2. the correct option is a because the blood plasma is responsible for the pH maintenance and
works with lungs and kidney to maintain the pH of the body fluids by maintaining the acid and
base ratio.
3. The correct option is a because the low levels of chloride level suggest that the body is losing
the ions away during vomiting along wth the food particles.
4. The correct option is b because the level of enzymes that are released by the invading cells for
the destruction of the proteins of the extracellular matrix which separates the cancer cells and the
adjoining tissue. The level of degrading enzymes is responsible for the proliferation and escape
of the cancer cell into the surrounding tissue.
5. The option is b killer t cells.
6. The correct option is e. because the Herpes viruses are transmitted through skin to skin contact

2. in humans. mainly when in contact with infected person.
