question 1. In Stress, the sympathetic-adrenal mechanism
is activated, and it is achieved through? Thyroid hormone
Epinephrine and nor-epinephrine Mast cells
B-lymphocytes The correct answer is Epinephrine and nor-epinephrine To achieve the sympathetic-adrenergic mechanism,
the adrenergic fibers(sympathetic) of the autonomic nervous system are stimulated to

of the heart to pump? Hypovolemic
Cardiogenic Septic
Neurogenic The correct answer is Cardiogenic Cardiogenic shock
is caused by the failure of the heart to pump an adequate amount of blood to the vital organs.
This reduction in cardiac output means that the amount of blood that reaches the vital
organs is not adequate for tissue perfusion 3. The causes of Neurogenic shock may include
all of the following, except? Spinal anesthesia
Surgery Psychic trauma
Pulmonary embolism The correct answer is Pulmonary embolism Neurogenic shock may be caused by spinal anesthesia,
surgery, and drugs that inhibit the sympathetic nervous system, and psychic trauma such as
fear, worry, and emotional tension 4. An inflammatory response to a pathogenic
organism is termed as? Inflammation
Allergy Infection
Anaphylaxis The correct answer is Infection 5. If bacteria spread from the local site
into the bloodstream is known as? Bacteremia
Septicemia Secondary infection
Toxins The correct answer is Bacteremia Bacteria spread from the local site into the
bloodstream is known as Bacteremia When bacteria are present, growing and producing
toxins into the bloodstream, the infection is called septicemia
6. Which of the following is not a factor influencing inflammation?
Age Sex
Nutrition Adequacy of blood supply
The correct answer is Sex Factors influencing Inflammation
Age Nutrition
Adequacy of blood supply Availability of WBC
Immune response Hormonal influence
7. What is the full of ‘TIGH’? Time, Incidence, Goal and Hormone
Total Intake of Growth Hormone Tetanus Immune Globulin, Human
None of these The correct answer is Tetanus Immune Globulin,
Human Tetanus Immune Globulin, Human or TIGH
Nonimmunized persons are started on a tetanus immunization series and also given TIGH
TIGH is administered intramuscularly in high doses;
part of the dose may be infiltrated around the wound
8. What is the other name of gas gangrene? Septicemia
Candidiasis Diabetic foot
Clostridial myositis The correct answer is Clostridial myositis 9. An infection that involves the soft tissue
of the fingertip is called? Paronychia

and underneath the nail is called paronychia An infection that involves the soft tissue
of the fingertip is called a felon. 10. The type of cells are
those which constantly multiply throughout life replacing those cells being destroyed?
Labile cells Stable cells
Permanent cells Bone cells
The correct answer is Labile cells Labile cells:- Cells of the skin
and mucous membrane, blood cells Stable cells:- The cells do not multiply vigorously
throughout life but do so if injured and if an underlying structure present. Eg:- Osteoblasts
and functional cells of glandular organs Permanent cells:- These cells are unable to
regenerate and in which repair is by scar tissue. Eg:- Muscle cells, nerve cells of
CNS, cell bodies of peripheral nerves. 11. Which of the following factor is not affecting
the healing process? Color of the skin
Age Foreign bodies
Hormonal influence The correct answer is Color of the skin Factors that affect healing
Age Nutrition
Adequate blood supply Foreign bodies
Hormonal influence 12. A substance that when introduced into
an animal elicits the formation of specific antibodies is known as?
Foreign body Antigen
Antibody Immunity
The correct answer is Antigen 13. Which type of immunoglobulin consists
of 75 – 85% in blood? IgA
IgE The
correct answer is IgG 14. Which immunoglobulin is known as macroglobulin?
The correct answer is IgM IgM is a large molecule and is often called
the macroglobulin. Because of its size confined to the blood, where it is mainly involved
in providing protection against bacterial and viral invaders.
15. Why gamma globulin preparation is not administered intravenously?
Not effective Large quantity
Thick preparation Causes a severe anaphylactic reaction
The correct answer is Causes severe anaphylactic reaction The isolated gamma globulin preparations tend
to form small protein aggregates, and these if injected intravenously, could lead to severe
anaphylactic reactions. For this reason, the material is always administered intramuscularly.
16. Which one of the following is not included in four classical
signs of inflammation? Calor
Rubor Callous
tumor The correct answer is Callous Four Classical signs of Inflammation

or remembered response is a characteristic of both B and T cells system. The prior contact
with the antigen is stored in special memory cells of both
cell lines 21. Tuberculin reaction is an example of?
Anaphylactic reaction Cell-mediated reaction
Cytotoxic reaction Immune complex reaction
The correct answer is Cell-mediated reaction 22. A large amount of citrated blood given
over a short period of time causes? Hyponatremia

Hypercalcemia The correct answer
is Hypocalcemia Each unit of PRBC or FFP contains approximately
3 g of citrate used as a preservative and anticoagulant. It binds with serum calcium
