As several municipalities conduct nurse\u2010led hip ultrasound screenings during newborn and infant home visits, nurses must acquire the accurate technique smoothly and effectively. Clarifying the challenges nurses face when performing ultrasound procedures helps support effective education. This study aimed to identify challenges inexperienced nurses face when performing basic ultrasound using the Graf\u2010method in home settings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Descriptive case study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Ultrasound training was provided to 22 nurses in Japan to enable use during newborn and infant home visits. We analyzed 25 video cases from three nurses who required &gt;\u2009180\u2009s to obtain a standard plane image. Videos were transcribed and inductively analyzed to identify challenges with reference to Yin\u2019s case study methodology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Conditions of the challenges were categorized into knowledge, skills, and attitudes with reference to Bloom\u2019s taxonomy. The knowledge gap led to the failure to correctly judge whether the femoral head\/standard plane was captured. Skill deficiencies led to failure to move the probe vertically and difficulty maintaining the infant\u2019s straight lateral position. The combination of inadequate knowledge and skills resulted in failures to (1) place the probe directly over the femoral head, (2) display the image in the correct position and orientation, and (3) move the probe correctly regarding direction and range while maintaining the image in the correct position and orientation. Regarding attitude gaps, nurses failed to improve the procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n
