This document discusses several methods for calculating pediatric drug dosages based on age, weight, and body surface area. It presents Young's rule, Dilling's rule, Fried's rule, and Clarke's rule for calculating dosages based on age and weight. It also provides formulas for calculating intravenous fluid rates for children of different weights. Finally, it outlines the Glasgow Coma Scale for assessing level of consciousness in children, scoring eye opening, verbal, and motor responses on a scale of 1 to 5 or 6 points.

2. A. Dose calculation related to age
1. Young’s rule
Child’s dose = Age(year) * adult dose
Age (year)+ 12

3. 2. Dilling’s rule
Child’s dose = Age(year) *adult dose
20
3. Fried’s rule
Child’s dose = Age(months) *adult dose
150

4. 1. Clarke’s rule
Child’s dose = Body wt.(lb) *adult dose
150
Child’s dose = Body wt.(kg) *adult dose
70
# 1kg= 2.2 lb

5. Child’s dose = Child’s BSA *adult dose
150
BSA= body surface area

6. 1. 0-10 kg = wt.(kg)*100 ml/kg/day
2. 10-20 kg = 1000ml+ [wt.(kg)*50 ml/kg/day
3. >20 kg = 1500ml+ [wt.(kg)*20 ml/kg/day

7.  Drops/min = total volume [ml]* drop factor
total time[min]
Drop factor
Micro drip delivers 20 drops/min
Macro drip delivers 60 drops/min

8. S.
N
Children over 2 years Children below 2 years score
A. Eye opening response
1. Spontaneous opens with
blinking
Eye opening
spontaneously
4 points
2. Opens to verbal command Eye opening to speech 3 points
3. Opens to pain Eye opening to pain 2 points
4. None No eye opening 1 points
B. Verbal response
1. Oriented and converses Infant coos or
babbles(normal)
5 points
2. Confused but able to
answer questions
Infant is irritable and
continually cries
4 points
3. Inappropriate responses,
words are discernible
Infant cries to pain 3 points
4. Incomprehensible
speech/sounds
Infant moans to pain 2 points

9. 5. None No verbal response 1 points
C. Motor Response
1. Obeys commands for
movement
Infant moves
spontaneously or
purposefully
6 points
2. Purposeful movement to
painful stimulus
Infant withdraws from
touch
5 points
3. Withdraws from pain Infant withdraws from pain 4 points
4. Abnormal (spastic)
flexion, decorticate
posture
Abnormal flexion to pain
for an infant( decorticate
response)
3 points
5. Extensor (rigid) response
decerebrate posture
Extension to pain(
decerebrate response)
2 points
6. None No motor response 1 points

10. Scoring
13 – 15= mild brain injury
9- 12 = moderate brain injury
3- 8 = severe brain injury
