Q

You are searching the literature for the highest level of evidence for the effectiveness of low glycaemic index (GI) diets on the reduction of blood sugar levels. You would therefore look for:

A. Case studiesn
B. Systematic reviews
C. Randomized double blind controlled trials
D. Prospective cohort studies

A

C. Randomized double blind controlled trials

16
Q

You explain to the pt that type 2 diabetes differs from type 1 primarily in that type 2 diabetes:

A. The pt is totally dependent on an outside source of insulin
B. There is decreased insulin secretion and/or increased cellular resistance to insulin that is produced
C. There are islet cell antibodies and insulin autoantibodies that destroy beta cells in the pancreas
D. The C-peptide chain of proinsulin secreted by the pancreas cannot be removed by the liver, resulting pin a lack of active insulin

A

B. There is decreased insulin secretions and /or increased cellular resistance to insulin that is produced

17
Q

A pt recovering from diabetic ketoacidosis asks you how acidosis occurs. Your best response is:

A. Excess glucose in the blood is metabolized by the liver into acetone, which is acidic in nature
B. An insulin deficit promotes metabolism of fat stores, which produce large amounts of acidic ketones
C. Insufficient insulin leads to cellular starvation and, as cells rupture, they release organic acids into the blood
D. When an insulin deficit causes hyperglycemia, then proteins are deaminated by the liver, causing acidic by-products

A

B. An insulin deficit promotes metabolism of fat stores, which produces large amounts of acidic ketones

19
Q

In a study where TED stockings and a calf stimulator were found to be significantly more effective in preventing post operative DVTs (deep vein thrombosis) that TEDs alone, the significance level would be:

20
Q

A pt with hypovolaemic shock has a unrinary output of 30 ml/hr. You understand that the compensatory physiological mechanism that leads to altered urinary output is:
