You went to a sub center as pa of an audit. How many infants should be registered with a health worker working there?
(A) 50 (B) 100 (C) 150 (D) 200
(B) Ans: B. 100Ref: K Park, 23d ed., pg. 524, 567Estimated no. of infants in a health sub centre covering 5000 population can be calculated as follows:No. of live bih = Bih rate x Population/ 1000= 20.4 x 5000/1000 = 102Infant moality for sub centre = No. of live bih x IMR/1000= 102 x 34/1000= 3.5 (for calculation purpose we assume it 4)Therefore, total number of infants = 102 -- 4= 98Hence correct answer is 100 (nearest value).
