This feels like I'm taking BS Nursing

I know that taking Bachelor of Science in Nursing is too mainstream in this generation because honestly there are too many nurses. Some registered nurses (actually most) that I know don't work in hospitals for example. Anyway, in my TLE class, it really feels like I'm taking BSN because it's all about home nursing! Well, I got to know some techniques in home nursing a sick or ill person.
 
1.  If you are a good home nurse, what are the various home nursing techniques that you need to apply that will make the patient feel comfortable and speed up the recovery?

 If I am a good home nurse, I will regularly change the bed linens so that the bacteria or virus won't spread because if it will spread...now, we don't want everyone to get infected and sick right? I must check the vital signs of the patient also. Wow, I really feel like a nurse now. Just FEEL. Hahaha. I should also give the patient a bath. Gosh. I cannot imagine giving a patient a bath! I never did that yet because giving him/her a bath would mean that I should you know...his/her private parts =))))

2.  Why should the home nurse monitor the vital signs of the patient?
 The home nurse should monitor the vital signs of the the patient so that he/she can know if the patient's sickness is getting worse or not. The home nurse can know if the patient's body temperature is high or low through using a clinical thermometer in the mouth, armpit, and rectum. The patient can take the pulse rate, respiratory rate, and blood pressure of the patient. What if the patient was suffering from high blood pressure and you don't notice it? That's why you need to check his/her vital signs!

3.  How do you take the body temperature, pulse rate, respiratory rate and blood pressure of the patient?
There are 3 different parts of body (mouth, armpit, rectum) where you can take your body temperature. I am going to instruct you how to take your body temperature through the rectum because it is the rarest used.
1. Apply lubricant to the bulb (such as baby oil or petroleum jelly).
2. Gently insert the thermometer into the patient's rectum.
3. Hold it firmly in position for two minutes.
4. Remove it, wipe, then read the body temperature.
5. Record the body temperature.
6. Wipe it with cotton which was immersed in antiseptic.
7. Return the thermometer to its case.       

4.  What are some practices that the home nurse must follow that will promote comfort to the patient?
THE HOME NURSE MUST BE APPROACHABLE AND CHEERFUL. Let's say the home nurse is not always smiling, won't the patient be intimidated? That means the patient is not comfortable enough with the nurse. THE HOME NURSE SHOULD BE NEAT AND CLEAN. That is a must. How will the home nurse take care of a sick patient if he/she is not clean? It's a discomfort for both of them.

5.  How will you differentiate signs from symptoms of illnesses and diseases?
From what I've understood, 'signs' are those signs that the doctor can see and observe from the patient while the 'symptoms' are those what the patient himself/herself can observe and feel, etc. That's it :)

6.  If you are the doctor, what will be your basis in giving the diagnosis for your patient?
My diagnosis will be the signs and symptoms of the patient. The patient should be really honest with this because it'll become worse if the patient and doctor didn't understand each other, then the doctor ends up giving the wrong diagnosis. Tsk tsk tsk.
