    The WHO criteria for near miss maternal mortality include various indicators that suggest severe maternal morbidity. These indicators include the requirement of vasoactive drugs, shock, and acute thrombocytopenia with platelet counts below 1,00,000. However, oxygen saturation of less than 90% for more than 60 minutes is not included in the WHO criteria for near miss maternal mortality. This means that a prolonged period of low oxygen saturation alone does not meet the criteria for near miss maternal mortality according to the WHO.

    • C.

      B lymphocytes

    • D.

      Mature dendritic cells

    Correct Answer
    D. Mature dendritic cells
    Explanation
    Activation of T cells need 2 sets of signals:

    1] T cell receptor complex (TCR with CD4+ or CD8+) on the T cells should bind with the Major Histocompatibility Complex (MHC) on the Antigen Presenting Cells (APC).

    2] Non specific costimulatory signal due to the interaction of the costimulators present on the antigen presenting cells.

    Mature dendritic cells have the highest number of costimulators.

    Therefore, they are the most potent activators of naive T cells.

    • C.

      CD 30

    • D.

      CD 33

    Correct Answer
    D. CD 33
    Explanation
    CD 33 is the marker for granulocytic sarcoma. Granulocytic sarcoma, also known as chloroma or myeloid sarcoma, is a rare extramedullary tumor composed of immature myeloid cells. CD 33 is a cell surface marker that is typically expressed on myeloid cells, including granulocytes. Therefore, the presence of CD 33 can help identify and diagnose granulocytic sarcoma. CD 10, CD 13, and CD 30 are not specific markers for granulocytic sarcoma.

    Which of the following is true regarding Maraviroc?

    • A.

      Bind to transmembrane glycoprotein

    • B.

      Not active orally

    • C.

      Targets the CXCR4 receptor

    • D.

      Impairs immune surveillance

    Correct Answer
    D. Impairs immune surveillance
    Explanation
    Maraviroc is a CCR5 receptor inhibitor.
    It interferes with the attachment of HIV virus to the host cell.
    It has no effect on the strains of HIV which are tropic for CXCR4 receptor.
    It is given orally.
    Impaired immune surveillance can result due to blocking of human chemokine receptor CCR5.

    Most potent fluoroquinolone against Mycobacterium leprae is?

    • A.

      Levofloxacin

    • B.

      Ofloxacin

    • C.

      Moxifloxacin

    • D.

      Ciprofloxacin

    Correct Answer
    C. Moxifloxacin
    Explanation
    Ciprofloxacin has poor activity against Mycobacterium leprae.
    Ofloxacin, Pefloxacin, Moxifloxacin and Sparfloxacin have high level of activity against Mycobacterium leprae.
    Among them, Moxifloxacin is the most potent.

    • D.

      It is a glycoprotein.

    Correct Answer
    D. It is a glycoprotein.
    Explanation
    Inhibin is secreted by the sertoli cells in males and by the granulosa cells in females.
    It inhibits the secretion of Gonadotrophin Releasing Hormone.
    It is a glycoprotein with molecular weight between 10,000 and 30,000.

    • C.

       Activity is increased in protein deficiency

    • D.

      Activity is increased by glucocorticoids

    Correct Answer
    B. Increases chondrogenesis
    Explanation
    Somatomedin increases glucose oxidation in fat.
    Activity of somatomedin is reduced by protein deficiency and glucocorticoids.
    It has insulin like effect on tissues and causes lipolysis and increased glucose and amino acid transport by muscle.

    Most important mechanism which gets triggered in the first few hours after large increase in salt and water intake is?

    • A.

      Small increase in arterial pressure

    • B.

      Suppression of angiotensin II formation

    • C.

      Activation of low pressure receptor reflexes

    • D.

      Stimulation of natriuretic systems

    Correct Answer
    C. Activation of low pressure receptor reflexes
    Explanation
    As sodium intake is increased, sodium output initially lags slightly behind the intake.
    This time delay causes small increase in cumulative sodium balance.
    This leads to slight increase in extracellular fluid volume.
    This increase in extracellular fluid volume triggers various mechanisms in the body to increase sodium excretion.
    On intake of large quantities of salt and water, signals from the stretch receptors of the right atrium and the pulmonary blood vessels go to the brain stem.
    This will inhibit sympathetic nerve activity to the kidney.
    This in turn leads to decrease in tubular sodium reabsorption.
    This mechanism is most important in the first few hours after large increase in salt and water intake.
