Directions: The fasting blood sugar level (F) and the postprandial blood sugar level (PP) of a patient were monitored for four weeks W1, W2, W3, W4, and the reading ( in mg/d1) for four weeks were as follows:
F/PP: 170/220, 150/180, 120/150, 90/120
These have been presented through a bar graph. The normal range is considered to be :
F/PP : 70 - 100/100 - 130.
During which week was the fasting blood sugar level of the patient approximately 115.4% above the upper limit of normal PP blood sugar level?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. W2.
Given that:
Normal range of Fasting blood sugar level (F) = 70 - 100
Normal range of Postprandial blood sugar level (PP) = 100 - 130
Now, according to the question
During which week was the fasting blood sugar level of the patient approximately 115.4% above the upper limit of normal PP blood sugar level
⇒ 115.4% ~ 115%
Upper limit = 130
⇒ 130 × 115% = 149.5
⇒ 149.5 is smaller than 150
Hence,
In W2 the fasting blood sugar level (F) is approximately 115.4% of the upper limit of normal PP blood sugar.
