Question 1
1 / -0

The main function of the white blood cells in the human intestine system is to :

A
Combat and destroy antigenic particles.

B
Produce antigens to combat antibodies.

C
Carry oxygen around the body.

D
Transport antigens to B memory cells in the lymph nodes.

Solution

White blood cells or leucocytes are colourless, irregularly shaped and bigger sized cells than the RBC containing nucleus. WBCs are the cells, that help the body to fight infections. They combat and destroy the antigenic particles.
Thus, the correct answer is option A.
Question 2
1 / -0

The first open heart surgery was performed in

A
1945

B
1953

C
1967

D
1893

Solution

The first open heart surgery was done in 1893 by Daniel Hale Williams, a surgeon in Chicago, USA.
Question 3
1 / -0

Which of the following reveals the muscle disorders?

A
ECG

B
EEG

C
EMG

D
All of the above

Solution

Electromyography (EMG) measures muscle response or electrical activity in response to a nerves stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle. The electrical activity picked up by the electrodes is then displayed on an oscilloscope (a monitor that displays electrical activity in the form of waves).
Question 4
1 / -0

A child's blood group is `O'. The parents blood groups cannot be

A
AB and 0

B
B and 0

C
A and B

D
A and A
Question 5
1 / -0

Identify the correct sequence, that leads to the formation of a blood clot:
(A) Blood clot                     (B) Injury
(C) Factor II                     (D) Factor III
(E) Factor IV                     (F) Fibrinogen
(G) Thrombin

A
$$B\rightarrow C\rightarrow D\rightarrow F\rightarrow G\rightarrow A$$

B
$$B\rightarrow C\rightarrow G\rightarrow F\rightarrow A\rightarrow D$$

C
$$D\rightarrow B\rightarrow C\rightarrow G\rightarrow F\rightarrow A$$

D
$$B\rightarrow D\rightarrow C\rightarrow F\rightarrow G\rightarrow A$$
Question 6
1 / -0

In a medico-legal case of accidental interchange between two babies in a hospital, the baby of blood group A could not be rightly given to a people

A
With both husband and wife of group 0

B
Husband of group 0 and wife of group A

C
Husband of group A and wife of group 0

D
Both husband and wife of group A

Solution

The correct option is A.
If both parents have blood group O, then they possibly cannot give birth to a baby of blood group A due to absence of antigens of A in their RBC.
Question 7
1 / -0

A woman of blood group `O' presented a baby of blood group `O' which she claimed as her child. She brought a suit against a man of 'AB' group as the father of the child.

Which statement is correct as per your judgement

A
The father and mother claimed are the true persons

B
Father is true and mother is not the true person

C
Both the parentage claims are false

D
Mother is the true person and father claimed is not true
Question 8
1 / -0

When whole blood is stored with an anticoagulant at $$4^oC$$, the K+ ions move out from the RBC into the plasma. The most likely reasons for this is that

A
RBC haemolyses and hence leakage of K+ ions

B
K+ ions become more mobile at $$4^oC$$

C
Active transport ceases resulting in ionic equilibrium

D
The anticoagulant attracts the K+ ions into the plasma
Question 9
1 / -0

Which of the following substances, if introduced into the bloodstream, would cause coagulation of blood at the site of its introduction?

A
Fibrinogen

B
Prothrombin

C
Heparin

D
Thromboplastin

Solution

Thromboplastin is a lipoprotein produced by platelets at the site of injury and helps in clot formation. Thus if it is introduced into the bloodstream it would cause clot formation. Thromboplastin is the one which initiates the clotting process. Fibrinogen and prothrombin are two plasma proteins which help in the clotting process only when thromboplastin is present. Heparin is a natural anticoagulant present in blood which prevents the blood clotting in the blood stream.
So, the correct answer is 'Thromboplastin'
Question 10
1 / -0

An ECG gives information of:

A
Brain

B
Ventricles

C
Atria

D
Both (B) and (C)

Solution

Electrocardiogram (ECG) is a test that records the heart's electrical activity. ECG is used to detect and study many heart problems, such as heart attacks, arrhythmias and heart failure along with other disorders that affect heart function.
