Probably the most uncomfortable place a nurse could take a person’s temperature would be in the rectal area. However, that must be done in some situations. In most cases, when a nurse takes a temperature of a person especially a child, they usually take it in the mouth or under the armpit for a child.
However, that just gives the nurse an about temperature and not a real amount. If a nurse really wanted to monitor a patient’s body temperature, but she needed an exact temperature due to the problem, then she would need to take it rectally. This is usually done because the patient’s ailment is quite severe and an exact temperature is needed especially for those with cardiac problems.
When caring for a client with a cardiac disorder, the nurse should avoid using the rectal route to take temperature. Using this route could stimulate the vagus nerve, possibly leading to vasodilation and bradycardia. The other options are appropriate routes for measuring the temperature of a client with a cardiac disorder.
