A client with colitis inquires as to whether surgery eventually will be necessary. when teaching about the disease and its treat
AlladinOne [14]
The correct answer is that "for most clients, surgery is recommended only if non-surgical treatments have been unsuccessful." This is because of the guidelines involving medicine and surgery as well as guidelines involving the treatment of colitis. The question should have specified what type of colitis is the patient having, whether infectious or autoimmune. In infectious colitis, then surgery almost has no role and medical treatment with antibiotics as well as supportive therapy and fluid replacement are the only ones needed. In autoimmune colitis such as Crohn's disease or ulcerative colitis, while immunosuppressor drugs may have a role, surgery may be the mainstay of treatment especially those who are at risk of malignant degeneration.

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.
