1. Exocrine glands are glands that retain ducts to body surfaces. Most glands of the body are exocrine types with ducts connecting to anatomical surfaces; salivary, sweat. Endocrine glands are therefore referred to as "ductless" glands. Endocrine glands are the hormone producing structures of the body; pancreas, thyroid. Ugh, only one answer per question ><

Answer is B. Patients with diabetes suffer localized, not spinal damager from the disease. Both small and large diameter axons are affected, but larger are affected more greatly due to the microvascular changes and basement membrane thickening due to AGE (sugar product buildup) damage in the vasculature. Diabetes does not typically directly affect spinal columns/nerves. Diabetic neuropathy is a peripheral disease.

It depends, we don't know what format your bibliography needs to be in. Typically, I would say that they're in APA format. So, here's a website where you can look it up. http://www.liu.edu/cwis/cwp/library/workshop/citapa.htm
2 :
Some of the links don't work. but what you do is organize them in alphabetical order. by the author's last name. and if the piece of work doesn't have an author.... then start with the title first. you should do mla format for this, if you can "Author and/or editor names Name of the database, or title of project, book, article Any version numbers available Date of version, revision, or posting Publisher information Date you accessed the material Electronic address, printed between carets ([<, >])."

ANegative0 B+++1.5 pm/L I know patient B is suffering from diabetes mellitus but is it type I or II and why?? yep have found an insulin result Patient A= 5.5 ng/ml Patient B= 0.22 ng/ml So Patient B is a Type I diabetic. Thanks for your answers.

Umm ... B may be a type 1. Did "B" take insulin with their meal? What kind? It seems to me that a type 2's insulin would be released more quickly (since their pancreas still produces) so the sugars wouldn't peak that high that fast. Those numbers look like something my daughter would get ... though if she's at 279 at the end of 2 hours then she's not getting enough insulin. This is my totally uneducated opinion :o) I'm not sure you're going to find anyone in this forum that can help you with your homework. --edit-- Mr Peachy, a type 1 does eventually come back down without insulin. The sugar comes out with their urine, that's why there's increased urination and thirst. It just doesn't come down fast enough, and usually not far enough.
2 :
Could be type two since the numbers seem to be coming back down. Not enough info to tell for sure. If the patient were a type one and wasn't treated, it would probably continue upward. The reason is, a type two produces insulin which, despite it not working all that well, will eventually bring the glucose levels down. An untreated type one has no insulin to bring the levels back to normal. Either way, this patient needs help.
3 :
You will need to know this if you are to work with diabetics. You must really understand what you are learning. B is a Type 1 because: -The very high sustained elevated blood glucose readings. -Positive urine ketones -Low insulin levels. Research autoimmune Type 1 diabetes to learn WHY this occurs, and how it is different from Type 2 diabetes.

In untreated type 1 and type 2 diabetes mellitus

In untreated type 1 and type 2 diabetes mellitus...?
the fasting blood glucose concentration is below 4 - 6 mmol L-1 True/False??

I don't know for sure, because the measurement you are using is unfamiliar to me. Here in the US, the measurement for well controlled blood sugar is a reading between 70-120 mg/DL (milligrams per deciliter). I think your measurement is in moles and conversion from one measure to the other depends on molecular weight. But, as I recall the conversion for blood sugar is to divide 70-120 mg/DL by 18 which would yield a range of 3.8-6.6 mmol.
2 :
False. Normal fasting blood glucose is that level. Untreated diabetics have levels above 11,1 mmol/l

Discuss the patientâ€™s diagnosis of Type 1 Diabetes Mellitus. How would you diagnosis a child with this

Discuss the patientâ€™s diagnosis of Type 1 Diabetes Mellitus. How would you diagnosis a child with this?
Case Study #1: Diabetes Hannah is a 10-year-old girl who has recently been diagnosed with Type 1 Diabetes Mellitus. She is a 4th grade student at Hendricks Elementary School. Prior to her diagnosis, Hannah was very involved in sports and played on the girls volleyball team. Her mother is concerned about how the diagnosis will affect Hannah. 1. Discuss the patientâ€™s diagnosis. Include a definition of the actual disease or condition. Type 1 Diabetes Mellitus once known as â€œjuvenile onsetâ€ diabetes or â€œinsulin-dependent diabetes mellitus,â€ is a chronic disorder of carbohydrate, fat, and protein metabolism caused by inadequate production of insulin by the pancreas or faulty use of insulin by the cells. Insulin is a hormone needed to convert sugar (glucose) into energy. Although type 1 diabetes can develop at any age, it typically appears during childhood or adolescence. 2. Identify the factors which could have caused or lead to the particular disease or condition. 3. Describe the signs and symptoms which are associated with the disease or condition. 4. Discuss the diagnostic testing that is usually performed in order to formally diagnose the particular disease or condition. 5. Identify the appropriate treatment (including therapies, medications, etc) which the patient may be prescribed for his/her particular diagnosis. 6. Discuss potential barriers to therapy which the patient may experience due to their unique situation. 7. Discuss alternative treatments which may also benefit the patient. 8. Describe the typical prognosis for a patient with the disease or condition. 9. Identify patient teaching which would benefit the patient in your case study. I have to do a paper for school and looking for a good website to answer these question.
