Normal Temperature
36–38°C (96.8–100.4°F)
Normal Adult Pulse
60–100 beats/min
Normal Respiratory Rate
12–20 breaths/min
Normal SpO₂
Usually 95–100% in most adults
Bradycardia
Heart rate less than 60 beats/min
Symptoms of Bradycardia
Dizziness, weakness/fatigue, fainting, and hypotension
Tachycardia
Heart rate greater than 100 beats/min
Causes of Tachycardia
Fever, pain, anxiety, exercise, dehydration, and hypoxia
Tachypnea
Respiratory rate greater than 20 breaths/min
Bradypnea
Respiratory rate less than 12 breaths/min
Fever
Elevated body temperature; 39°C (102.2°F) is a fever
Effects of Fever
Can increase heart rate, respiratory rate, sweating, chills, and flushed skin
Temperature Increase
As temperature increases, heart rate usually increases
Hypothermia
Body temperature below normal; 35°C (95°F) is an example
Nursing Care for Hypothermia
Keep the client warm, use warming blankets when appropriate, monitor vital signs, and watch for complications
Radiation
Heat loss from the body to a cooler surrounding surface or environment without direct contact
Conduction
Heat loss through direct contact with a cooler object or surface
Convection
Heat loss caused by moving air or fluid around the body
Evaporation
Heat loss when liquid on the skin changes into vapor, such as sweating
Sweat
Heat is lost through evaporation
Proper BP Technique
Client should be relaxed, with feet supported and legs uncrossed
Correct BP Cuff Size
Use the correct cuff size for the client's arm
BP Cuff Placement
Place the cuff on the bare arm
Cuff Artery Marker
Align the artery marker with the brachial artery
BP Cuff Location
Place the cuff 2–3 cm (about 1 inch) above the antecubital space
Arm Position for BP
Arm should be supported at heart level
Why Correct Cuff Size Matters
An incorrect cuff size can cause an inaccurate blood pressure reading
BP Documentation
Record BP, arm/site, client position, and method/equipment when needed
BP Documentation Example
BP 118/72 mm Hg, right arm, sitting
Brachial Artery
Artery in the upper arm used as the reference point for blood pressure cuff placement
Normal Adult Pulse
60–100 beats/min
Pulse Strength 0
Absent
Pulse Strength 1+
Weak or faint
Pulse Strength 2+
Normal
Pulse Strength 3+
Strong
Pulse Strength 4+
Bounding
Apical Pulse Location
5th intercostal space at the left midclavicular line
When to Count Apical Pulse for 60 Seconds
When an accurate measurement is needed or with certain cardiovascular medications
Apical Pulse
Heartbeat heard directly over the apex of the heart using a stethoscope
Normal SpO₂
Usually 95–100% for most adults
SpO₂ 93–94%
Assess the client and compare the reading with their baseline and clinical condition
Factors Affecting Pulse Ox
Poor circulation, cold extremities, movement, nail polish/artificial nails, and poor peripheral perfusion
Capillary Refill Less Than 2 Seconds
Generally indicates adequate peripheral perfusion
Pulse Ox and BP Cuff
Avoid placing the pulse oximeter on the same extremity as an automatic BP cuff when possible
Acute Pain Activates
The sympathetic nervous system and fight-or-flight response
Effects of Acute Pain
Can increase heart rate, blood pressure, respiratory rate, pupil dilation, and sweating
Pain Vital Sign Pattern
Pain can cause HR ↑, BP ↑, and RR ↑
Orthostatic Hypotension
A drop in blood pressure after changing position, especially when standing
Orthostatic Vital Sign Order
Supine → Sitting → Standing
Symptoms of Orthostatic Hypotension
Dizziness, lightheadedness, weakness, fainting, and increased fall risk
First Orthostatic Measurement
Start with the supine/baseline measurement
Athletes and Resting Heart Rate
Athletes may normally have bradycardia or a lower resting heart rate
Why Athletes Have Lower Resting HR
Improved cardiovascular conditioning can result in a lower resting heart rate
Assessing a Low HR in an Athlete
Consider the client's normal baseline and whether the client has symptoms
SOAP Charting
