Module 7 Vital Signs

What is included in taking Vital Signs?

Temp
Pulse
Respiration
Blood Pressure

How often should vital signs be assessed?

-Upon admission
-Before and After surgical or invasive diagnostic
-Before giving meds that affect cardio or resp function
-anytime there is a change in patients condition

What should you ask a patient before taking their oral temp?

Have they had anything to eat or drink in the past 15-30 mins
Also goes for smoking or chewing gum

What is important to ask a patient before taking their blood pressure?

What is their normal blood pressure?

How do you know how high to pump the gauge when taking a blood pressure?

Ask patient what their normal blood pressure is and pump 30 above that.

What is the primary source of heat loss?

The skin

Which method of taking temp is the most accurate in adults?

Rectal
But it is also the most invasive

medical term for an elevation in body temperature

Pyrexia or hyperthermia

medical term for having a fever

Febrile

Medical term for decreased body temp

Hypothermia

Mechanisms of Heat Loss

1) RADIATION - ex: taking off a hat to cool head or removing a blanket
2) CONDUCTION - ex: ice packs , wash cloths.
3)EVAPORATION - ex: sweating
4)CONVECTION - ex: Air Conditioning or a fan blowing on you

More on 4 mechanisms of heat loss

1. Radiation-transference of heat from the surface of one object to another
WITHOUT contact
. Ex-I'm cold so I will go outside
2. Conduction-transference of heat from one object to another
WITH direct contact
. Ex-ice packs, heating pads, cooling blankets

Where do you insert an oral thermometer for taking temp?

Posterior Sublingual Pocket

When is rectal temp contraindicated?

In newborns, children with diarrhea, rectal disease, or rectal surgery
* not usually used for patients with heart disease/surgery bc bradycardia can be caused by stimulating the Vagus nerve

When is tympanic temp contraindicated?

Not used with patients who have drainage from the ear
*ear wax does not effect temp

What method of taking temp is used with newborns?

Axillary Temp

What should nurse do if vital is abnormal?

Document it and then notify the HCP

Pulses are caused by what?

contractions of the left ventricle of the heart

Amount of blood that enters the arteries with each ventricle contraction is called ____ ____

Stroke Volume

Pulse characteristics for dehydration

Fast yet thready pulse

Pulse characteristics for congestive heart failure.

Fast yet bounding pulse

Pulse over 100 beats/min in adult

Tachycardia

Pulse less than 60 beats/min in adults

Bradycardia

Locations of Peripheral Arterial Pulses

Carotid Artery
Brachial
Radial
Dorsalis Pedis

Normal pulse range for adults

60-100

An irregular rhythm is called ____

Dysrhythmia

What are you checking for when taking Dorsalis Pedis pulses?

Bilateral equality
& circulation to the feet

What can you use if you have trouble palpating a pulse?

A doppler ultrasound

Where is the apical pulse located?

Between the 5th and 6th intercostal spaces and to the left of the midclavicular line

Resp Rate greater than 24 breaths/min

Tachypnea

Resp Rate slower than 10 breaths/min

Bradypnea

Normal Resp Rate range is ____

12-20 breaths a min

Normal inspiration and expiration (or volume) of air exchanged with each breath

Tidal Volume (about 500 ml)

term meaning difficulty with breathing

Dyspnea

BP with systolic 140 mmHg or higher

Hypertension

BP with systolic less than 90 mmHg

Hypotension

Systolic pressure is a result of:

contraction of the ventricles
This is the maximum pressure against arterial walls

Diastolic pressure is a result of:

Ventricles relaxing and refilling with blood
This is the minimal pressure exerted against arterial walls

the difference between the systolic and diastolic pressure

Pulse pressure

Normal blood pressure range is

120 / 80 mm Hg
