The dilation (expanding; getting larger) of the vein which helps increase heat loss through the skin to cool off the body.
What is the definition of vasoconstriction?
The constriction (shrinking; getting smaller) of the vein which helps reduce heat loss through the skin to keep the body warm once it’s cooled off.

What is the medical term for fever?
pyrexia
What are the main functions of a fever?
- Inhibit bacteria growth
- Increase WBC production
- Stimulates interferon (virus fighting substance)
Patterns of fever: Constant/Sustained
Remains above normal
Patterns of fever: Intermittent
Returns to normal at least once per 24 hours
Patterns of fever: Remittent
Does not return to normal, fluctuates up or down
Patterns of fever: Relapsing
Returns to normal for 1 or more days; episode of fever lasting several days
Why would a nurse change damp clothes and sheets?
To prevent bed sores, as well as, keep the patient cool and clean
Why would a nurse check vital signs every 4 hours if a patient has a fever?
To see if the vitals have either changed or contributed towards the temperature. Also, to see if there is a cause of the fever.
Why would a nurse cover a patient lightly if they have a fever?
To keep the patient from over heating while still giving them comfort, protection, and privacy.
Why would a nurse encourage high fluid intake for a patient that has a fever?
To help prevent dehydration from sweat.
Why would a nurse offer light foods frequently to a patient that has a fever?
So the patient has the nutrients to fight off whatever the fever is trying to get rid of. (Raise metabolism)
Why would a nurse keep a patient with a fever on bed rest?
To prevent the fever from rising to dangerously high levels from movement or exercise.
What is the normal range for pulse rate?
60-100BPM
What is the range for bradycardia?
<60BPM
What is the range for tachycardia?
> 100BPM
What does the pulse rate assess?
- Heart function
- Tissue perfusion
- State of blood vessels
What are the 9 pulse sites?
- Radial
- Temporal
- Carotid
- Apical
- Brachial
- Femoral
- Popliteal
- Dorsalis pedis
- Posterior tibial
What is the location of the Apical Pulse?
Between the 5th and 6th rib; 5th intercostal; midline of the clavicle down.
How long do you count the Apical Pulse?
1 full minute.
What could be the reason be for a pulse deficit between the apical and radial pulses?
Atrial fibrillation
Absent, not palpable pulse
0
Diminished, weaker than expected pulse
+1
Brisk, expected (normal) pulse
+2
Bounding pulse
+3
What is the definition of a regular rhythm when it comes to pulse?
Beats and pauses occur at regular intervals.
What is the definition of irregular rhythm when it comes to pulse?
Beats and pauses occur at unequal intervals.
What are the 4 pain things to check when assessing perfusion (circulation)?
- Color of the skin
- Warmth of the skin
- Blanching or capillary refill
- Pulses
What factors influence pulse rates?
- Age and gender
- Physical activity

- Medications
- Disease
What is the range for normal rate of respirations?
12-20BPM
What are the 3 processes involved in respiration?

What is the definition of ventilation?
Movement of air in and out of the lungs
What is the definition of hyperventilation?
Excessive (potentially dangerous) movement of air in and out of the lungs.
What is the definition of hypoventilation?
Less than normal movement of air in and out of the lungs.

CO2 and O2 exchange between lungs and blood

CO2 and O2 exchange between blood and cells
Why should you not tell the patient you are counting their respiration?
They may change their breathing patterns.
What is the definition of eupnea?
Normal breathing

What is orthostatic hypotension?
Occurs when a patient with a normal BP develops symptoms and a low BP when rising to an upright position.
