Importance of heat application
- Reduces pain sensation
- Promotes vasodilation
importance of cold application
- Slows pain sensation
- Reduces inflammation
importance of counterirritant
- To relieve pain
- To divert patient’s attention
indication of Heat Application

SCIENTIFIC PRINCIPLES involved in heat and cold application
- Anatomy and physiology
- Microbiology
- Chemistry
- Physics
- Psychology
- Time and energy
EFFECTS OF HEAT APPLICATION
Mostly increase (Vasodilation)
- Decrease muscle tension
- Decrease blood viscosity
- Decrease venous congestion
EFFECTS OF COLD APPLICATION
Mostly decrease (Vasoconstriction)
- Increase muscle tension
- Increase blood viscosity
- Increase venous congestion
GUIDELINES in heat and cold application
- Determine client’s ability to tolerate the therapy
- Identify conditions that may contraindicate treatment
- Explain the application to the client
SCIENTIFIC PRINCIPLES in parenteral meds
Microbiology
Pharmacology
Anatomy and Physiology
Chemistry
Psychology
Sociology
Safety and Security
Time and Energy
Physics
ADVANTAGES OF PARENTERAL MEDS
- It provides a precise dose to the targeted area of the body
- Useful for clients who are in a mental or physical state that make other routes difficult of impossible
DISADVANTAGES OF PARENTERAL MEDS
- Can result to adverse metabolic effects like dehydration, hyperglycemia, hypoglycemia, infection etc.
- Patients are at a risk for unsafe injection practices which can cause infection
FACTORS AFFECTING parenteral meds
- Body mass index
- Angle of insertion
- Route
- Age
- Length of needle
- Circulatory status
Parts of a needle
- Bevel
- Shaft or cannula
- Needle hub
Types of syringe
- Hypodermic syringe
- Hypodermic needle
- Insulin syringe
- Tuberculin syringe
Parts of syringe
- Tip
- Barrel
- Plunger
Types of needle gauges
- Type of tissue being penetrated
- Medication’s viscosity or how thick and sticky it is
