1. Daily Routine
a) Opening Prayer
c) Checking of attendance
B. Review the Past Lesson
The teacher will ask the students about the previous topic discussed.
1. What is Home Nursing?
2. How can home nursing affect the patient’s recovery?
“Charades” a group game in which some of the students will try to guess a word or situation that is related to taking body temperature and home nursing, from the actions of another student who may not speak.
2. Definition of Terms
a) Body Temperature- refers to the degree of hotness or coldness of the body as shown by a thermometer. b) Thermometer- it is an instrument used for measuring temperature. The units used are degree Celsius (⁰C) or Fahrenheit (⁰F).
3. Lesson Proper
An effective home nurse knows what to do with a patient and how to deal with his or her needs. This lesson will discuss on how to measure body temperature accurately, that can help speed up the patient’s recovery.
Our body’s normal temperature is more or less 37⁰C or 98.6⁰F. A rise in body temperature means fever and could indicate infection.
There are two kinds of Clinical Thermometer used to measure body temperature:
* Rectal Thermometer- has a more rounded bulb to protect the sensitive tissues of the rectum. This type of thermometer is ideal for babies and young children.
* Oral Thermometer- has an elongated bulb used in taking temperature from the armpit or from the mouth. This is popularly used for older children, adults and elderly who could tolerate a thermometer in the mouth or keep them snugly in the armpit.
Other instruments that measures body temperature:
* Digital Thermometer- is an instrument that measures body temperature from a finger. It is run by a battery. A beeper signals if the temperature is ready to be read through a quartz display. This can be used in taking the armpit (axilla) temperature.
* Thermograph strip- this is a strip of plastic with numbered black strip that change in colour when heated by contact with the body (the forehead). It can only be used indoors, away from things that give out heat. The strip changes colour when it stops (about 15 seconds), the temperature is read while still on the forehead.
* Thermo scan – an infrared ear thermometer that functions as a photo camera. This is inserted into the ear canal and surrounding tissues. The temperature is displayed in the screen in just one second.
General Principles in taking body temperature
1. Rectal temperature is about 1⁰F or .5⁰C higher because rectal veins in the area elevate the temperature slightly. Normal reading is 99.6⁰ F or 37.5⁰C so that in any reading, a corresponding 1⁰F or .5⁰C must be deducted to get the exact temperature.
38.5⁰C is the actual temperature
2. Axilla temperature is about 1⁰F or .5⁰C lower as it is already located outside the body. So this needs to add 1⁰F or .5⁰C to any reading.
