Haemorrhagic shock (HS) is a subset of hypovolaemic shock in which there is minimal to massive loss of blood either internally or externally in trauma or injured patients. Data from the World Health Organization (WHO) affirm that injuries account for over 5 million fatalities globally every year, and by 2030, injury mortality is predicted to rise severely. Public health research typically uses the KAP models, which may be divided into three parts: acquiring accurate knowledge, forming an attitude, and adopting behavior, to analyze people’s health behaviors and explain changes in them. This review is about the nurses’ perspectives of the concept of Knowledge, Attitude, and Practice (KAP) Model of hemorrhagic shock in trauma patients and assesses clinical practice tools used by nurses to keep an eye on patients who have the condition. Nurses’ knowledge of indications of shock is either high or very high. The knowledge of nurses was related to their training before working in accident and emergency units. The nurses’ attitude is considered significant, commendable, appropriate, and pertinent to the provision of care for a patient experiencing hemorrhagic shock. And the nurse’s practice of early patient identification, prompt and continuous monitoring, control of the bleeding source, maintenance of hemostasis, and the correction of significant blood loss that can occur quickly to cause death, are the strengths of management.
