What is a Fever? Low and High Grade

Nurses routinely assess a patient's temperature to assess patient status, the effectiveness of treatment, and to monitor the progression of disease processes.

Knowing what is a "fever" and what is not a "fever" is not as straight forward as one might think. We often use terms such as low grade and high-grade temperature and knowing when to call the physician is an important nursing skill.

Review how the body regulates our body temperature from the thermostatic control center in the hypothalamus to the ways our body adjusts for changing temperatures.

Revisit the patterns of fever ... yes patterns ... that give you some insight into how bacteria, viruses, fungus, parasites, and other injuries and diseases such as Stroke, Hodgkin's Disease and trauma as it relates to intracranial pressures all work to reset our temperature and cause fevers.

Discussions around typical treatments such as antipyretics, fluids, rest, cooling techniques included to help you anticipate what might be recommended to care for your fever.

Neurogenic fever is also discussed with the specific signs of an unrelenting fever that does not respond to antipyretics and the absence of sweat!

I have noticed that I can touch 37.5 and even 37.6 (taken orally)sometimes in the afternoons...always have normalish results in the morning and evenings. I don't usually feel "feverish" at these higher temperatures. Is that a cause for concern?
Also, is it true that tympanic thermometers give higher temperatures? I'm thinking of purchasing one, but dont wanna freak myself out if it gives higher readings.

For past 8 months or so, I’ll have 36.6 in the morning but reach up to 37.8 early to late evening oral temp and feel flushed. Have had an array of tests, all normal except slightly abnormally high inflammatory blood markers and borderline persistent enlarged lymph nodes. Was wondering if this is just normal fluctuation or would be cause for concern of Hodgkins as this has been daily and very uncomfortable. Thanks

I have had a temperature of 38-39.5 for the past 2 days, should I get it checked? I have had a bad headache as well

[christywhite]

I run around 97.2 early morning then afternoon 98.2 late afternoon 98.8- 99.0 then back down before i go to sleep 98.5

[nicolettethebaguette]

I have an ear infection and have a fever but besides my ear hurting I feel fine... like I was feeling fine but disided to check my temperature and was shocked when I saw 38° on it.

[chloesouthern]

I'm obsessed taking my temp and every day even in the morning its 37.3 and sometimes it can go to 37.8 had blood tests all normal. Im worried its a bit high.

[JK-tdky]

I am pretty thirsty and have no fever according to thermometer but feel hot. No cough. I hope it’s not covid

[saltpan]

my average temp is 97.5-97.9 always. last couple of days has been 98.6-98.9. Would this be a fever.

[jessievb]

For women, during our cycle, our temperatures go up as well don’t they? But do they go up drastically or just change a little. For example from 98.6 to 99?

[bridgetmaynez]

I had a high fever few years ago.I came into the dr just tired and he gave me meds and it made my fever get higher. He never figured out was wrong with me. He did I whole bunch of test and had no idea what I had.it was weird though bc I only felt tired, I didn’t feel hot or amazing else

[pjlincaro]

Having an feverish feeling. But checking time to time using digital temp, it ranges 36.4 - 36.7. Is this a fever?

[Rosanmohanty]

I am recently recovered from Covid. Still My body temperature ( oral) is always around 99.5 F . Although Doctors are saying, it is normal to shift the body thermostat from 98.4 to 99.4F ( post viral syndrome), i am little freaking out

[Izunia]

OK so please if someone can help me... Ive been having a low grade fever for like 10-12 days now...mostly around evening time or in afternoons my body gets a bit hot like around 99.0-99.8F and at around 5-6 p.m. in the evening it reaches to like 100.0-100.4F and no more than that..that is the time when i take a tablet for fever and then my body temperature after 1-2 hours returns to normal like around 98.7 and so and then for next 24 hours im ok and then again the next day around the same evening time i again get a bit feverish and again take a tablet and then again my temperature goes normal...
I've consulted a doctor and he told me that its a normal viral fever which lasts long... He also wrote me a course of medicines for 5 days which consisted of antibiotics...I had a bit of relief after that for like 2-3 days and then again this weird thing started .... Not to forget to mention im also having a bit of a dry cough (like i cough very little its not too much and sputum isn't produced much only a little bit)... I got my blood test done and X-ray done and my blood test report was pretty much normal except the fact that me ESR level was high.. and i have a small patch in my lung (saw it in the xray)
Which doctor told me is infectious and it maybe pneumonia or tuberculosis...now the thing is im very active and not feeling any sort of weakness or so and im not even having loss in apetite nor im spitting blood.. but the doctor was also a bit confused and told me to get a CT scan done... I consulted a few more doctors and they told me not to worry its not serious its a normal viral infection which is normal these days... I don't know what to believe and what to do please help

My father had a fever of 100.8 last night and today his fever fluctuated many times it was normal but around 4 in the evening it was 97 and at 7 :30 at night it was still like 37.0 degree but after 2 and half hour his fever got high it was around 102.1
What does this mean??

[baybaymarino]

First day is 37.2 then went higher at 37.4, following days dips to 36, but then head feels warm to touch, this eighth day reading is 37.4, have cough by the way...feeling fatigued and some rashes at back by the way, could this rashes be because of perspiring between the first day and sixth day ...? Am thinking to go for swab test....please advise

[lienemeid]

I’m wondering if these numbers are referring to temperatures taken orally, axillary or rectally? Thank you for this video!
