AIIMS Paramedical Nursing Previous Year Question Paper With Solutions For Biology

1. Bicarbonate ion is produced inside:

a) Basophils

b) Erythrocytes

c) Neutrophils

d) Lymphocytes

Answer: (b) Erythrocytes

Explanation: In erythrocytes, which are also known as red blood cells is the cell is where bicarbonate ion production takes place. In the cell, some carbon dioxide binds to haemoglobin, forming carbaminoglobin. The carbonic anhydrase enzyme present in red blood cells quickly converts carbon dioxide and water into bicarbonate and hydrogen ions. So the correct answer is 'Erythrocytes'.

2. Reduction in the pH of blood will:

a) Release bicarbonate ions by the liver

b) Decrease the affinity of haemoglobin with oxygen

c) Reduce the blood supply to the brain

d) Reduce the rate of heartbeat

Answer: (b) Decrease the affinity of haemoglobin with oxygen

Explanation: Reduction in pH of blood causes oxygen haemoglobin dissociation curve to shift to the right, which indicates dissociation of oxygen from haemoglobin. This decreases the affinity of haemoglobin for oxygen.

3. The amount of air exchanged in breathing can be measured with a:

a) Barometer

b) Sphygmomanometer

c) Spherometer

d) Spirometer

Answer: (d) Spirometer

Explanation: Spirometry is the process of recording the changes in the volume movement of air into and out of the lungs, and the instrument used for the purpose is called a spirometer or respirometer.

4. For reaching left side of heart, blood must pass through:

a) Kidneys

c) Lungs

b) Liver

d) Brain

Answer: (c) Lungs

Explanation: The deoxygenated blood pumped into the pulmonary artery is passed on to the lungs, from where the oxygenated blood is carried by the pulmonary veins into the left atrium. Hence, for reaching the left side of the heart, blood must pass through the lungs.

7. Two blocks of masses 5 kg and 2 kg are placed on a frictionless surface and connected by a spring. An external kick gives a velocity of 14 m/sec to the heavier block in the direction of the lighter one. Velocities of two blocks in the centre of mass frame, just after the kick, are respectively given by:

a) 10 m/s, - 10 m/s
