Chapter 29 – Vital Signs Vital signs include body temperature, pulse (HR), respiratory rate (RR), blood pressure (BP), oxygen saturation (SpO2), pain They are checked to monitor the functions of the body WHEN to assess vital signs o On admission o If a client’s health status changes, i.e. chest pain, feeling hot or faint o Before/after surgery or invasive procedure o Before/after medication administration (affecting respiratory or cardiovascular system) o Before/after intervention affective VS, i.e. ambulating pt after bedrest Prior to delegation – Is the pt medically stable & VS are routine (stable), UAP may measure record & report, nurses role is to make assessment & interpret the results Body temperature – Reflects the balance between the heat produced and the heat lost from the body, measured in degrees Core temperature- temperature of the deep tissues of the body, remains constant, ex: abdominal or pelvic cavity Surface temperature- temperature of the skin, subcutaneous tissue, and fat; changes with environment Heat is produced as a by-product of metabolism Heat balance- amount of heat produced = amount of heat lost Factors that affect the body’s heat production – Basal metabolic rate – (BMR) rate of energy utilization in the body required to maintain essential activities such as breathing. Metabolic rates decrease with age.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
