質問 1

The patient's BUN is within normal range (5-20 mg/dL) while the creatinine is about five times the upper normal range (0.6-1.2 mg/dL). Gross elevations in creatinine are almost always accompanied by elevations in BUN when there is kidney impairment. Either the BUN or creatinine value in this case is incorrect. Both tests should be repeated.
A patient's BUN value is 15 mg/dl and his creatinine is 5 mg/dl. If this patient is not undergoing dialysis, what conclusion would you draw from these results?

（A）one of the values is in error

（B）patient has suffered muscle deterioration

（C）patient is in early stage of renal disease

（D）patient is normal

（E）patient protein intake is quite low

（A）lower urinary tract infections

（B）massive muscle trauma

質問 11

Gram-positive bacteria retain the primary crystal violet stain that is applied in the Gram stain because of the cross-linking of the thick peptidoglycan layer in their cell walls. Their cell walls contain less lipids than that of a gram-negative bacteria, and this reduces the permeability of their cell wall to the organic solvents that are used as a decolorizer. When the counterstain is added, it may enter the gram-positive cell, but does not change the color of the cells.
A thick peptidoglycan is MOST often associated with which of the following types of bacteria?

（A）Gram-negative bacteria

（B）Gram-positive bacteria

（C）Both gram-negative and gram-positive bacteria

正解：B 解答を投票する

質問 12

In excess triglycerides, the triglycerides reduce the amount of cholesterol in LDL particles producing small dense LDL molecules. Because of size and density, these molecules more easily enter damaged endothelium and vessel walls and are more easily incorporated as plaque is formed.
Which statement best describes small dense LDL particles that can occur in atherogenic dyslipidemia?

（A）Small dense LDL molecules transport more cholesterol and thus are more atherogenic

（B）Small dense LDL molecules are less atherogenic than larger, less dense or buoyant LDL particles because they are metabolized faster

（C）Small dense LDL molecules are more atherogenic because they can more easily move into the endothelium and vessel wall

正解：C 解答を投票する
