Background: As you do not know the path of the wind or how the body is formed in a mother’s womb, so you cannot understand the work of GOD, the maker of all things. The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The Placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it.
Objectives: 1. to assess the knowledge regarding development of placenta and umbilical cord among antenatal mothers before and after SIM. 2. To associate the level of knowledge regarding development of placenta and umbilical cord with selected socio demographic variables of antenatal mothers before and after SIM.
Materials and Methods: A quantitative research approach was adopted to assess the effectiveness of SIM on knowledge regarding development of placenta and umbilical cord among antenatal mothers. Quasi experimental non-equivalent control group design was used to assess the effectiveness of structured instructional module on level of knowledge between the variables under each section. The samples were selected by using Non – probability convenience sampling technique. The setting of study in Narayana General Hospital and Narayana Superspeciality Hospital, Nellore. Sample size was determined by using single population proportion formula with the assumptions of 95% level of confidence, 10% proportion on knowledge of antenatal mothers on development of placenta and umbilical cord, 4% of margin of error. Finally considering a non-response rate of 8%, the total size was calculated to be 500 antenatal mothers with all trimesters. Among them 250 assigned as experimental group and 250 as control group.
Result: The results reveals that effectiveness of SIM considering the overall aspects, antenatal mothers are gain more knowledge after the administration of the SIM. This 60.82% of knowledge gain is the net benefit of the study which indicates the effectiveness of SIM.
