Weekly Quiz Competition

Question 1
1 / -0

Which one of the following proteins is involved in the coagulation of blood

A
Globulin

B
Fibrinogen

C
Albumin

D
Serum amylase.

Solution

Fibrinogen is soluble protein that is produced by the liver and found in blood plasma. It is one of the 13 coagulation factors responsible for normal blood clotting or coagulation of blood. When tissue damage results in bleeding, fibrinogen is converted at the wound into fibrin by the action of thrombin, a clotting enzyme.
So the correct answer will be option B.
Question 2
1 / -0

Assertion. Blood group 'O' has both anti-A and anti-B antibodies
Reason. It does not have any antigen

A
A

B
B

C
C

D
D.
Question 3
1 / -0

Which one takes part in blood clotting

A
RBC

B
WBC

C
Thrombocytes

D
Lymphocytes.

Solution

C. Thrombocytes
EXPLANATION: Thrombocytes are small pieces of very large cells called megakaryocytes, which are present in the bone marrow. They help to form blood clots to stop bleeding and to help wounds heal. Having too many or too few thrombocytes may be indicative of diseases.
Question 4
1 / -0

Fastest distribution of some injectable material/medicine and with no risk of any kind can be achieved by injecting it into

A
Artery

B
Vein

C
Muscle

D
Lymph vessel.

Solution

B. Vein
EXPLANATION: 'Intravenous' means 'within a vein'. The intravenous root is the fastest way compared to deliver medicines throughout the body. Intravenous therapy is also known as IV therapy.
Question 5
1 / -0

Life span of blood platelets is

A
1 - 2 days

B
2 - 3 days

C
3 - 4 days

D
5 - 9 days.

Solution

D. 5 - 9 days
EXPLANATION: Platelets can survive only about ten days, before they are removed from the bloodstream. A low numbers of platelet may also be called thrombocytopenia. The symptoms are severe bleeding and are possibly fatal, if it is not treated.
Question 6
1 / -0

Given here is ECG of a normal human. Which one of its components is correctly interpreted

A
QRS complex - one complete pulse

B
Peak T - initiation of total cardiac contraction

C
Peaks P and R - systole and diastole blood pressure

D
Peak T - initiation of left atrial contraction only.

Solution

A) The QRS complex represents the electrical impulse as it spreads through the ventricles and indicates ventricular depolarization. The QRS complex starts just before ventricular contraction and is the complete pulse.
B) The T wave represents the repolarization of the ventricles. Cardiac relaxation takes place.
C) The P wave represents the depolarization of the atria This happens right before the atria contract and push blood into the ventricles. R represents the peak of the ventricular contraction. Systole corresponds to contraction while diastole corresponds to relaxation. The P and R peaks only signify a systole.
D) T wave signifies the relaxation of the whole heart (diastole).
So the correct answer is 'QRS complex - one complete pulse'.
Question 7
1 / -0

Which does not play any role in blood clotting according to Best and Taylor

A
Fibrinogen

B
Platelets

C
Calcium

D
Prothrombin.

Solution

According to the theory of Best and Taylor's, four components are involved in blood clotting. These are prothrombin, thromboplastin, fibrinogen and calcium ions. And platelets does not take any part in blood clotting.
So the correct answer will be option B.
Question 8
1 / -0

Choose the correct option about a - d.

A
a - eosinophil, b - lymphocyte, c - neutrophil, d - monocyte

B
a - erythrocyte, b - basophil, c - neutrophil, d -lymphocyte

C
a - eosinophil, b - monocyte, c - neutrophil, d - lymphocyte

D
a - eosinophil, b - erythrocyte, c - neutrophil, d- basophil
Solution
Correct Option: C
Explanation:
In the diagram,
a- depicts eosinophils, which are granulocytes with a bilobed nucleus.
b -denotes monocytes, which are agranulocytes with a kidney-shaped nucleus.
c- denotes neutrophils, which are granulocytes with a 2-5 lobed nucleus.
d -denotes lymphocytes, which are agranulocytes with a big concentrated nucleus.
Hence, the correct option about a-d is as follows, 'a - eosinophil, b - monocyte, c - neutrophil, d - lymphocyte'.
Question 9
1 / -0

What is correct regarding blood pressure?

A
105/50 mm Hg makes one very active

B
100/55 mm Hg is considered at ideal blood pressure

C
190/110 mm Hg may harm vital organs like brain and kidneys

D
130/90 mm Hg is considered as high and requires treatment

Solution

Blood pressure 190/110 mm Hg indicates high blood pressure or hypertension. Normal systolic and diastolic blood pressure in body is 140 mm Hg and 90 mm Hg respectively. Pressure above 140 mm Hg and 90 mm Hg is high blood pressure which can cause damage to vital organs like brain and kidney. High blood pressure can cause damage to blood vessels in brain and kidney. This can lead to rupture of blood vessels and cause brain haemorrhage. In kidneys, high blood pressure can lead to inadequate supply of blood to kidney and thus, resulting in decreased filtration.
So, the correct answer is '190/110 mm Hg may harm vital organs like brain and kidneys'.
Question 10
1 / -0

Foramen ovale:

A
Connects the two atria in the foetal heart.

B
Connects pulmonary trunk and aorta in foetus.

C
ls a condition in which heart valves do not completely close.

D
Is a shallow depression in the inter-ventricular septum.

Solution

Foramen ovale is a hole between the left and right atria (upper chambers) of the heart. It connects two atria in the foetal heart.
So the correct answer will be option A.
