2-20. WHEN SHOULD I TAKE A RECTAL TEMPERATURE?
a. A rectal temperature should be taken if one of the two following situations exists.
b. Do not take a patient's rectal temperature if one or more of the following conditions (contraindications) are present.
2-21. HOW DO I TAKE A RECTAL TEMPERATURE WITH A GLASS THERMOMETER?
Use the following procedures when taking a patient's rectal temperature.
a. Wash Hands. Perform a patient care hand wash.
b. Gather Materials. You will need to assemble the following items:
c. Verify That The Rectal Route Should Be Used. A rectal temperature should be taken when one of the following conditions exist:
d. Verify Patient's Identity. Be sure to verify that you are taking the temperature of the proper patient.
e. Tell Patient About Procedure. Tell the patient that you are going to take his temperature rectally. Be sure to explain how you want the patient to position himself (paragraph f) and inform him when you are going to insert and remove thermometer.
f. Position Patient. Have the patient to lie on his side with his top knee flexed (bent). (This is called the "Sims's" position.") Arrange the patient's clothing (gown, pajamas, etc.) and bed sheet so that the rectal area is clearly exposed, but so that the patient is not exposed unnecessarily.
g. Prepare Lubricant. Before the rectal thermometer is inserted, the bulb of the thermometer must first be lubricated. Your SOP will indicate what type of lubricant is to be used (usually a type of jelly or mineral oil). Prepare the lubricant by placing some of the lubricant on a gauze pad. If the lubricant is in a jar, a tongue depressor can be used to transfer some of the lubricant from the jar to the pad. A thermometer should not be dipped into a jar of lubricant since this action could contaminate the lubricant remaining in the jar.
h. Examine Thermometer. Pick up a thermometer from the "clean" container. Be sure to avoid touching the part of the thermometer that will be inserted into the patient's rectum. Make sure that the thermometer is a rectal thermometer (red color-coded and not long-tipped) and that its temperature reading is below 94º F.
i. Lubricate Thermometer. The bulb of the thermometer is lubricated in order to make it easier to insert the thermometer into the rectum and to keep the muscles inside the rectum from being irritated by a dry rectal thermometer. (If the muscles are irritated, they may contract and try to push the thermometer out of the rectum.) Lubricate the thermometer by putting the tip of the thermometer bulb into the lubricant on the gauze (figure 2-11). Then use the gauze pad to spread the lubricant over the entire bulb of the thermometer and over two inches of the stem. After you have lubricated the thermometer, discard the gauze pad into an appropriate waste container.
Figure 2-11. Lubricating a rectal thermometer.
j. Insert Thermometer. Insert the thermometer into the patient's rectum using the following steps:
Figure 2-12. Inserting a rectal thermometer in an adult patient.
Figure 2-13. Inserting a rectal thermometer in an infant.
k. Hold Thermometer in Place for Two Minutes. An accurate temperature reading can be obtained within two minutes. You must hold the thermometer in place during this time in order to prevent the thermometer from being expelled (pushed out) of the rectum and to prevent the thermometer from entering further into the rectum.
l. Remove Thermometer. After at least two minutes have elapsed, remove the thermometer from the patient's rectum.
m. Wipe Thermometer. Use a gauze pad to wipe the thermometer. Begin near the hand that is holding the thermometer and wipe to the bulb in one quick, downward stroke. Discard the used gauze pad into a waste container.
n. Read Thermometer. Hold the thermometer at eye level and read the temperature to the nearest 0.2 ºF (or 0.1º C).
o. Record Reading. Write the patient's temperature reading on the form or piece of paper. After you record the temperature reading, write a circled "R"( ® )above the reading. The ® indicates that the temperature is a rectal temperature rather than an oral temperature.
p. Place Thermometer in "Used" Container. After recording the patient's rectal temperature, place the used thermometer into the container marked "used" on the thermometer tray.
q. Wash Hands. Perform a patient care hand wash after taking a rectal temperature.
r. Turn in Tray. After you have completed taking rectal temperatures, turn in the temperature tray according to local procedures. The thermometers must be decontaminated before they are used again.
2-22. HOW DO I TAKE A RECTAL TEMPERATURE WITH AN ELECTRIC THERMOMETER?
If you are not familiar with the electric thermometer you will be using, read the instructions provided in the operator's manual or in your SOP before using the thermometer to take a patient's temperature. The general procedures for taking a patient's temperature with an electric thermometer are given below.
a. Wash Hands. Perform a patient care hand wash before beginning the procedure.
b. Gather Materials. You will need the following items:
c. Verify That The Rectal Route Should Be Used. Any situation that will prevent you from taking the patient's rectal temperature with a glass thermometer will also prevent you from taking his rectal temperature with an electric thermometer.
d. Verify Patient's Identity. Make sure that you are taking the temperature of the proper patient.
e. Prepare Thermometer. Make sure that the electric thermometer is working and ready to use.
f. Tell the Patient About Procedure. Tell the patient that you are going to take his temperature rectally. Explain to the patient how he is to position himself (paragraph g). Inform him before inserting or removing the probe.
g. Position Patient. Have the patient to lie on his side with his top knee flexed in the Sims's position. Arrange the patient's clothing and bed sheet so that the rectal area is clearly exposed, but the patient is not unnecessarily exposed.
h. Prepare Lubricant. Place some of the lubricant onto a gauze pad. If the lubricant must be transferred from a jar or similar container, use a tongue depressor or similar instrument to put the lubricant onto the pad.
i. Cover Probe. Insert the rectal probe into a probe cover.
j. Lubricate Probe Cover. Put the tip of the probe into the lubricant. Then use the gauze pad to spread lubricant over the lower part of the probe cover. Dispose of the gauze pad after the probe cover is lubricated.
k. Insert Probe. Insert the probe into the patient's rectum using the following steps:
l. Wait for Signal. Hold the temperature probe in place until the thermometer signals (red light, etc.) that the patient's temperature has been determined.
m. Remove Probe. If you have released the patient's upper buttock, raise the buttock again. Then carefully remove the probe from the patient's rectum. After the probe has been removed, release the patient's buttock and cover the patient again (reposition gown, pajamas, bed sheet, and so forth).
n. Read and Record Temperature. Read the patient's temperature from the display and record the reading. If the electric thermometer does not display the temperature rounded to the nearest 0.2º F or 0.1º C, round off the patient's temperature to this degree of accuracy. Write " ® " above reading to indicate that the temperature is a rectal temperature.
o. Discard Probe Cover. Eject the probe cover into a waste container.
p. Return Probe to Resting Place. Return the probe to its resting place. If additional actions are required to reset the temperature display to be used again, perform those actions.
q. Wash Hands. Perform another patient care hand wash.
