21. A 4 hrs old neonate has
arterial pO2 of 100,
pCO2=30. He is on FiO2 of
0.4.
Calculate the a/ApO2 ratio?
RQ=1

22. A. ApO2= FiO2 (760-47) - PCO2/RQ
ApO2= 0.4(760-47)-30/1 =255
A. apO2/ApO2 = 100/ 255
= 0.39

37. Steps for Gram staining ?
- 5 marks

38. 1. Make a slide of tissue or body fluid that is to be stained. Heat
the slide for few seconds until it becomes hot to the touch so
that bacteria are firmly mounted to the slide.
2. Add the primary stain crystal violet and incubate 1 minute.
3. Add Gram's iodine for 1 min. It is not a stain; it is a mordant. It
doesn't give color directly to the bacteria but it fixes the
crystal violet to the bacterial cell wall.
4. Wash with Decolorizer. If the bacteria is Gram-positive it will
retain the primary stain. If it is Gram-negative it will lose the
primary stain.
5. Add the secondary stain, safranin, and incubate 1 min, then
wash with water for a maximum of 5 seconds. If the bacteria is
Gram-positive then it will retain the primary stain and will not
take the secondary stain. It will look black-violet in a pink
background. If it is Gram-negative then it will lose the primary
stain and take secondary stain making it pink-red.

41.  Thefollowing is a table which
shows cigarette smoking and
lung cancer ?
Cigarette Developed cancer Did not devlop
smoking cancer
Yes 70 6930
no 3 2997
Calculate the relative risk ?

42. 1. RR= Incidence of disease in
exposed/Incidence of disease in non
exposed
2. Incidence of disease in exposed =
70/7000=10 per 1000
3. Incidence of disease in non
exposed=3/3000= 1 per 1000
4. So RR=10/1= 10
