Question 91
This Gram stain is under-decolorized
This microscopic field is representative of other fields that were observed on a Gram-stained smear. Which of the following describes the quality of the smear?
Question 92
The creatinine clearance for this patient is 100 mL/min.
Creatinine clearance values are calculated using the following equation:
Creatinine Clearance (mL / min) = (Urine Creatinine / Serum Creatinine) x Urine Volume (mL) / [ time (hr) x
60 ]
For this patient Creatinine clearance (mL/min)= (120/1.5) x (1800 / [24 x 60])
80 x 1800/1440, which is 80 x 1.25, or 100 mL/min
A 45-year-old male of average height and weight had a serum creatinine of 1.5 mg/dL and urine creatinine was
120 mg/dL; the total volume of urine collected over a 24-hour period was 1,800 mL. Calculate the creatinine clearance for this patient in mL/min.
Question 93
Either immunofixation or immunoelectrophoresis can be used to confirm Bence-Jones proteinuria.
Which of the following methods would be used to confirm the presence of Bence-Jones protein in the urine:
Question 94
Hypochromia can best be described as:
Question 95
Type I hyperlipoproteinemia is a form of hyperlipoproteinemia associated with deficiencies of lipoprotein lipase. Hyperlipoproteinemia type II is the most common form and is classified into type IIa and type IIb, depending on whether there is elevation in the triglyceride level in addition to LDL cholesterol.
Hyperlipoproteinemia type III is associated with high chylomicrons and IDL. Hyperlipoproteinemia type IV is assoicated with high triglycerides. It is also known as hypertriglyceridemia. Hyperlipoproteinemia type V is similar to type I, but with high VLDL in addition to chylomicrons.
An obese adult with premature arteriosclerosis is seen in the clinic. When her serum is tested no chylomicrons are present, LDL are normal and VLDL are increased. There is an increase in triglycerides and slight increase in cholesterol. Lipoprotein electrophoresis reveals a heavy pre-beta band. She has no skin rash and uric acid is increased. This patient has a hyperlipoproteinemia with the MOST likely type of:
