Q

Refer to Figure 34-3 on page 883 and complete the paragraph.
When there is high blood glucose in the body the pancreas releases _____. This causes the cells to take up _____ from the blood or the liver to produce _______. This allow the blood glucose to fall.

A

When there is high blood glucose in the body the pancreas releases INSULIN. This causes the cells to take up GLUCOSE from the blood or the liver to produce GLYCOGEN. This allow the blood glucose to fall.

Q

Fill in the blank

People with diabetes are at higher risk for ____ and ________ than people with out it.

Q

Fill in the blank

____________ amputations occur ________ frequently in people with diabetes

A

Nontraumatic, more

67
Q

What two terms refer to diabetes mellitus?

A

Diabetes, DM

68
Q

Type 1 diabetes was formally known as

A

Type 1 diabetes mellitus, juvenile onset diabetes mellitus, or insulin dependent diabetes mellitus (IDDM)

76
Q

High blood glucose levels lead to

A

Cataracts, blurred vision, and destruction of peripheral nerves. Resulting in parethesias.

77
Q

Treatment of diabetes is maintaining blood glucose levels through

A

Medications, diet, and exercise

78
Q

Three laboratory tests used to screen for DM are

A

Plasma glucose level (PG), fasting blood glucose (FBG) and oral glucose tolerance test (OGTT)

79
