Few fact/questions to answer. Please help!

allnurses Guide · May 17, 2012

I don't think anyone here will do your homework.

If you tell us what you think about these questions, we can help you from there.

I see you are new to All Nurses. You'll find that this is a great place to get opinions and information from a variety of people.

BUT, this is not a homework service. This is not a place to drop off your homework and come back later for the answers. (By the way- that's called cheating.) Work through the questions yourself and post your answers. If you still have questions or are headed in the wrong direction then there are lots of people here who will be more than willing to help clarify things for you and help you get back on track.

Most of your questions can be answered simply by consulting your text book or doing a quick internet search. please do your own homework. You'll find that getting other people to do work for you will not serve your well in the future.

Ashley is right! Welcome to AN! The largest online nursing community.

We are happy to help with homework but we will not do it for you. Learning how to critically think and be resourceful are important character traits to being a nurse. Nurses need to know how to find answers when they don't know where they are to better know how to care for the patients. Tell us what you think and we will help you and lead you to the correct direction.

Let me google that for you

here is what i've found so far: -- answers for some of the above questions.

They are both units of energy, but the dietary Calorie (note the use of upper case 'C') equals 1000 'physics' calories. The physics calorie represents an amount of energy needed to raise (or lower) one gram of liquid water by one centigrade degree. That amount of energy is too small to conveniently describe the energy content of food, so the physics 'kilocalorie' is used instead and is, confusingly, called simply a Calorie in dietary terminology. A food Calorie, then, is the amount of energy needed to change the temperature of one KILOGRAM of liquid water (a volume of one liter) one centigrade degree. The food Calorie is often spelled with an upper case 'C' to distinguish it from the smaller calorie.

Sterilization destroys all microorganisms, including bacterial

endospores.

Sterilization should be used for instruments, surgical gloves and other items

that come in direct contact with the blood stream or normally sterile tissues

(Spaulding 1939). It can be achieved by high-pressure steam (autoclave), dry

heat (oven), chemical sterilants (glutaraldehydes or formaldehyde solutions)

or physical agents (radiation).

Pascal's principle states that the fluid pressure at all points in a connected body of an incompressible fluid at rest, which are at the same absolute height, are the same, even if additional pressure is applied on the fluid at some place. That means that if you measure a person's blood pressure in their arm, at the same height as their heart, the pressure measured is the same as the pressure within the heart itself.

I just had 3 of 8.

No one is going to answer these questions for you. You should be able to answer these questions with a little googling and some critical thinking. For an example, if you understand Pascals principle, then you should understand how a manometer measures CVP and therefore why it is important to keep it upright.

Not to be mean but I think a couple of those questions such as # 3 you can answer on your own if you think about it. If a person is standing up gravity is going to pull the blood down, thus making it harder for blood to return to the heart. That is why it is important for a person to be mobile so you can contract your leg muscles to help with venous return.

And question number 2 look up Pascals theory and apply it to what you've learned. You have to be willing to put in the work to reap the benefits. Good luck!

see, this is why nursing school is so much different from standard academic subjects. you will be asked to take something you learned in prereqs (like pascal's principle) and think about how it works in a body. you will have to take what you learned about pressure changes and flow relating to tube diameter to figure out blood flow in the vascular system. you will have to apply what you know about heat transfer to a living, breathing body with a fever.

this is a start to getting you to think about these things, prompt you to go back to your prereqs books and look for the applicable material, and make a decision.

and this is just the start. remember how you learned chemistry? whole lotta chemistry going on inside your skin.
