Nursing Research Paper Introduction A study by Naugler and DiCarlo (2018) rates "Sudden Infant Death Syndrome" (SIDS) as one of the major causes of deaths of infants in the U.S. According to Moon, Hauck, and Colson (2016), more than 4000 SIDS-related infant deaths are registered in the U.S. every year (p.67). No precise causes of SIDS have been documented, but an apparent correlation has been found between both sleep environment and infant positioning and risks of SIDS (Myers, 2016). A preponderance of evidence demonstrates that nurses on Mother-Baby-Units are not as knowledgeable as they need be around AAP Safe Baby Sleeping practices, and that is why cases SIDS-related infants’ deaths have been on the rise (Naugler & DiCarlo, 2018; Bartlow et al., 2016). AAP baby sleeping practices are recommendations given by the APP (American Academy of Pediatrics) regarding how to establish a safe sleeping environment for newborns (Goetter & Stepans, 2005). This study will use both qualitative and quantitative research designs to investigate this problem: nurses on Mother-Baby-Units are not as knowledgeable as they need be around American Academy of Pediatric Safe Baby sleeping practices. Due to the limitation of literature on this topic, a combination of these two research designs will provide a richer and more detailed understanding of the overall knowledge nurses and parents about AAP safe baby sleeping environment and practices. Research design The study will be observational, qualitative and quantitative. Quantitative research will be conducted by using questionnaires while qualitative research will be conducted through observation. The study will be carried out at infant postpartum nurseries in two different hospitals (A and B) in New York City. Staff nurses handling infants in the two hospitals will not be informed capstonewriting.com NURSING RESEARCH PAPER 3 about the specific purpose of observation to avoid creating any alarms, but the directors of the nursing units will be made aware. Observations will be carried out in the postpartum nurseries where newborns are taken care of by registered nurses rather than caretakers or their mothers. No requests will be made to nurses to bring infants for observation. Each observation will include one observer who will observe the nursery at a particular time. Observers will note the position of infants (left-lateral, supine, prone or right-lateral) and other items within the crib of the infants like blankets. Anonymous self-administered questionnaires will be used to measure the attitudes and knowledge of nurses. The questionnaires will test the nurses’ knowledge about SIDs, their reported practice and attitudes toward SIDs. These questionnaires will strictly be distributed within the postpartum units after concluding observation. Sampling A convenience sampling approach will be used to select two hospitals in New York City. Simple random sampling will then be conducted to select a total of 60 nurses caring for infants in their nurseries (30 nurses from each hospital) to fill the questionnaire. The study will include observations of 88 infants and their crib environments in the two hospitals. Regular visits will be made in hospital A and B until 44 infants are observed in each hospital. Observations will be done in a three weeks period at random intervals. Inclusion criteria The inclusion criteria for the participants will be the two hospitals must have infant nurseries to be selected for the study. Only registered nurses, taking care of infants in the nurseries will be allowed to fill the questionnaire. Exclusion criteria The inclusion criteria for the participants will be hospitals without infant nurseries will not be selected for the study. Nurses in the t
