Mosby items and derived items © 2006, 2003, 1999, 1995, 1991 by Mosby, Inc. Slide 58 When Vital Signs Are Assessed ► Temperature, pulse, respirations, and blood pressure are usually assessed at the same time at set intervals. ► A set of vital signs is taken when the patient is admitted to the facility and then as prescribed by the physician or as policy dictates. ► Example: every 4 hours; once a shift; weekly

Mosby items and derived items © 2006, 2003, 1999, 1995, 1991 by Mosby, Inc. Slide 59 When Vital Signs Are Assessed ► The more ill the patient, the more frequently vital signs are taken. ► Vital signs are interrelated.  A rise in temperature of 1° F may cause an increase in pulse rate of 4 beats per minute.  Respiratory rate and blood pressure readings increase with a rise in temperature.  Blood pressure falls because of hemorrhage, the pulse and respirations increase and the temperature usually decreases.

Mosby items and derived items © 2006, 2003, 1999, 1995, 1991 by Mosby, Inc. Slide 60 Recording Vital Signs ► Graphic Flow Sheet  Used for charting vital signs  R indicates a rectal temperature  Ax indicates an axillary temperature  Blood pressures are always written with the systolic first and the diastolic beneath. ► Example: 120/80  Apical pulse is indicated with an “ap” after next to the number. ► Example: 78 ap

Mosby items and derived items © 2006, 2003, 1999, 1995, 1991 by Mosby, Inc. Slide 61 Recording Vital Signs ► Any abnormal findings are reported to the nurse-manager or physician immediately. ► Any accompanying or precipitating signs and symptoms such as chest pain, vertigo, shortness of breath, flushing, and diaphoresis should be recorded as well. ► The nurse documents any interventions initiated as a result of vital sign measurement, such as tepid sponging.
