To increase heat loss through conduction, provide a ______________

______ Pressure is measured in millimeters of mercury (mmHg)

Systolic Pressure is the pressure of the blood as a result of contraction of the ventricles, that is, the pressure of the height of the blood wave

Diastolic Pressure is the pressure when the Systolic and Diastolic ______ Pressure Measured in mm Hg Recorded as a fraction e.g. 120/80mmHg Systolic = 120 and Diastolic = 80

Pulse Pressure is the difference between the Systolic pressure and the Diastolic Pressure - normal PP is 40mmHg (at rest) - 100mmHg (exercise)

Determinants of Blood Pressure include A.Pumping Action of the Heart B.Peripheral Vascular Resistance C. ________

The apical rate would confirm the rate and determine the actual cardiac rhythm for a client with an abnormal rhythm; a radial pulse would only reveal the heart rate and suggest an ______________.

The radial pulse is appropriate for routine postoperative vital sign checks for clients with ______________ pulses.

It would be appropriate to delegate the taking of vital signs of which of the following clients to a UAP? A patient being prepared for elective ______________ surgery with a history of stable hypertension.

It would be appropriate to delegate the taking of vital signs of which of the following clients to a UAP? A patient receiving a blood transfusion with a history of transfusion ______________.

It would be appropriate to delegate the taking of vital signs of which of the following clients to a UAP? A client recently started on a new ______________ agent.

It would be appropriate to delegate the taking of vital signs of which of the following clients to a UAP? A patient who is admitted frequently with ______________ attacks.

Rate. Rhythm. Volume. Arterial wall elasticity. Presence/absence of bilateral equality. Apical-Radial Pulse Locate apical and radial sites Two nurse method: – Decide on starting time – Nurse counting radial says “start” – Both count for 60 seconds – Nurse counting radial says “stop” – Radial can never be greater than apical Copyright 2008 by Pearson Assessing the Pulse. Tachycardia – excessively fast HR. Bradycardia – Slow, less than 60bpm in adult Pulse Rhythm – pattern and interval of the beats. Dysrhythmia/arrhythmia – pulse rate with irregular rhythm. Assessing the Pulse Pulse Volume – the force of blood with each beat; aka pulse strength or amplitude - absent to bounding. Full/Bounding Pulse – obliterated with difficulty. Weak/Feeble/Thready Pulse – easily obliterated Pulse: Lifespan Considerations Infants Newborns may have heart murmurs that are not pathological Children The apex of the heart is normally located in the fourth intercostal space in young children; fifth intercostal space in children 7 years old Copyright 2008 by Pearson Education, Inc.

Middle 3 fingers are used with moderate pressure. Nurse should determine: Any medication that could affect the HR. If client has been physically active. Baseline data about normal HR. Whether client need to assume a particular position. Measuring Apical Pulse Copyright 2008 by Pearson Assessing the Pulse Data Collection: (Characteristics of Pulse) Rate.
