Question 1
1 / -0

A mismatch during transfusion of blood causes

A
Agglutination

B
Erythroblastosis

C
Haemopoies

D
None of the above.

Solution

A mismatch blood transfusion cause more or less severe intravascular hemolysis, which clump (agglutinate) the red blood cell. This is due to severe antibody reactions between circulating antibodies and the corresponding antigens of the mismatched red blood cells.
So, the correct option is A.
Question 2
1 / -0

For safe blood transfusion

A
Donor's RBC should not contain antibodies against recipient's serum

B
Recipient's serum should not contain antigens against donor's antibodies

C
Recipient's serum should not contain antibodies against RBC of donors

D
Recipient's RBC should not contain antibodies against donor's antigens.
Solution
- The presence of antigen on the surface of the red blood cell decides the type of blood group as shown in the given chart. Antibodies specific to these antigens are present within blood plasma (serum).
- AB is considered a universal recipient because it does not have anti-A or anti-B antibodies. That means it can accept blood with A antigen, B antigen, both the antigens or without A & B antigen present on the surface of RBC without generating an immune response.
So, the correct answer is option C.
Question 3
1 / -0

Murmur occurs due to defect in

A
Heart valves

B
SA node

C
AV node

D
Purkinje fibres.

Solution

Heart murmurs are the sounds produced in the heart that are indicative of defects in heart valves. These sounds can be heard using the stethoscope. The type of murmur produced could be indicative of the type of defect inside or outside the heart.
So, the correct answer is 'Heart valves'.
Question 4
1 / -0

In ECG deflection waves, ventricular systole occurs during

A
PQ

B
PQR

C
QRS

D
T
Solution
ECG (Electrocardiogram) represents the electric current that moves through the heart during a heart beat. An ECG shows five consecutive waves i.e. P, Q, R, S and T.
- P wave represents the depolarisation of atria when both the atria contract.
- QRS complex represents depolarisation of ventricles when ventricular systole i.e. contraction of ventricles occur.
- T wave represents ventricular repolarisation when ventricles return from excited state to normal state.
So, the correct answer is 'QRS'.
Question 5
1 / -0

Systole is contraction of

A
AV node

B
SA node

C
Major arteries

D
Atria and ventricles.
Question 6
1 / -0

Thoracic duct is associated with

A
Purkinje fibres

B
Hepatic duct

C
Innominate vein

D
Aorta.
Question 7
1 / -0

In ECG, P-wave represents _________.

A
End of atrial contraction

B
Beginning of atrial contraction/depolarisation

C
Beginning of ventricular contraction

D
None of the above
Solution
ECG consists of three components: P-wave, a QRS complex, and a T-wave.
The P-wave represents the beginning of the atrial contraction (atrial depolarisation).
The QRS complex represents ventricular contraction (ventricular depolarisation) and T wave represents ventricular relaxation (ventricular repolarisation).
Hence, the correct answer is option B, i.e., Beginning of atrial contraction/depolarisation.
Question 8
1 / -0

Systemic circulation of oxygenated blood starts from

A
Right atrium

B
Left atrium

C
Left ventricle

D
Right ventricle

Solution

Systemic circulation is the flow of blood from the left ventricle of heart to all parts of body and return of blood to the right atrium of heart. The oxygenated blood leaves the left ventricle through aorta and deoxygenated blood returns to the right atrium through superior and inferior vena cava. The purpose of systemic circulation is to transport oxygen and nutrients to body tissues and remove carbon dioxide and other wastes. Hence, systemic circulation of oxygenated blood starts from left ventricle.
So, the correct answer is 'Left ventricle'.
Question 9
1 / -0

Which one represents pulmonary circulation?

A
Left auricle (oxygenated blood) $$\rightarrow$$ lungs (deoxygenated blood) $$\rightarrow$$ Right auricle

B
Left auricle (deoxygenated blood) $$\rightarrow$$ lungs (oxygenated blood) $$\rightarrow$$ Right auricle

C
Left auricle (oxygenated blood) $$\rightarrow$$ lungs (deoxygenated blood) $$\rightarrow$$ Left auricle

D
Right auricle (deoxygenated blood) $$\rightarrow$$ lungs (oxygenated blood) $$\rightarrow$$ Left auricle
Solution
Pulmonary circulation is the flow of deoxygenated blood to lungs and return of oxygenated blood to the heart.
- Deoxygenated blood from the body parts is brought to right auricle by the vena cava.
- The blood is pumped to the right ventricle from the right auricle.
- From the right ventricle, deoxygenated blood is carried to lungs by pulmonary artery.
- The blood gets mixed with oxygen in the lungs and is carried to left auricle of heart by pulmonary vein.
So, the correct answer is 'Right auricle (deoxygenated blood) → lungs (oxygenated blood) → Left auricle'.
Question 10
1 / -0

$$Rh^-$$ mother carries $$Rh^+$$ foetus. The foetus is at risk of disease called

A
Haemophilia

B
Haemolytic disease

C
Tuberculosis

D
Syphilis.
