Respiratory Disorders Part 1

Increased asthmatic attacks in certain seasons are related to:

1. hot and humid environment

2. eating fruits preserved in tin containers

3. inhalation of seasonal pollen

4. low-temperature

Which two of the following changes (a – d) usually tend to occur in the plain dwellers when they move to high altitudes (3,500 m or more)?

(a)	Increase in red blood cell size
(b)	Increase in red blood cell production
(c)	Increased breathing rate
(d)	Increase in thrombocyte count

Changes occurring are:
1. (b) and (c)
2. (c) and (d)
3. (a) and (d)
4. (a) and (b)

People who have migrated from the planes to an area adjoining Rohtang Pass about six months back:

1.	Have more RBCs and their haemoglobin has a lower binding affinity to 02
2.	Are not physically fit to play games like football
3.	Suffer from altitude sickness with symptoms like nausea, fatigue, etc.
4.	have the usual RBC count but their haemoglobin has a very binding affinity to 02

Due to increasing air-borne allergens and pollutants, many people in urban areas are suffering from respiratory disorder causing wheezing due to:

1.	reduction in the secretion of surfactants by pneumocytes
2.	benign growth on mucous lining of nasal cavity
3.	inflammation of bronchi and bronchioles
4.	proliferation of fibrous tissues and damage of the alveolar walls

Given below are two statements: one is labeled as Assertion (A) and the other is labeled as Reason (R).

Assertion (A):	A person goes to a high altitude and experiences 'altitude sickness' with symptoms like breathing difficulty and heart palpitations.
Reason (R):	Due to low atmospheric pressure at high altitudes, the body does not get sufficient oxygen.

In light of the above statements, choose the correct answer from the options given below:

1.	(A) is true but (R) is false.
2.	(A) is false but (R) is true.
3.	Both (A) and (R) are true and (R) is the correct explanation of (A).
4.	Both (A) and (R) are true but (R) is not the correct explanation of (A).

Match List-I with List-II.

	List-I		List-II
A.	Emphysema	I.	Rapid spasms in muscle due to low Ca++ in body fluid
B.	Angina Pectoris	II.	Damaged alveolar walls and decreased respiratory surface
C.	Glomerulonephritis	III.	Acute chest pain when not enough oxygen is reaching to heart muscle
D.	Tetany	IV.	Inflammation of glomeruli of kidney

Choose the correct answer from the options given below :
1. A-II, B-IV, C-III, D-I
2. A-II, B-III, C-IV, D-I
3. A-III, B-I, C-IV, D-II
4. A-III, B-I, C-II, D-IV
