Question

1.

Review the following serum test results:
Creatinine:2.5mg/dL
Cholesterol:220mg/dL
Glucose:110mg/dL
Urea:40mg/dL
Uric acid:5.9mg/dL
These results are most consistent with:

Compromised renal function

Impaired glucose metabolism

Diagnosis of gouty arthritis

Chemotherapy treatment

2.

Calculate the corrected creatinine clearance using these data obtained from a person with a 1.73m2 body surface area:
Serum creatinine:1.3mg/dL
Urine creatinine:2.4mg/mL
Urine volume:1000mL/24h

119mL/min

128mL/min

139mL/min

167mL/min

3.

Use the following information for the next three questions. A four year old child has the following labs performed:
Urine creatinine = 67 mg/dLplasma creatinine = 0.4 mg/dL
24 hour urine volume = 430 mLbody surface area = 0.865 m2
Urinary protein = 8 mg/dL
The creatinine clearance indicates

Normal glomerular filtration rate

Compromised renal function

50% reduction of in number of functioning nephrons

Acute renal failure

4.

Which of the following is not usually considered to be a function of an automated analyzer?

Dilutions

Proportioning of reagent

Auto-verification

Incubation

Mixing

5.

Signal processing involves:

Analog-to-digital conversion of signals that is quite slow

Analog-to-digital conversion of signals that is quite rapid

Mainframe computers but not desktop and laptop computers

Very simple algorithms to produce meaningful output to health care providers

6.

What is the PRIMARY goal of laboratory automation?

Laboratory personnel reduction

Error prevention

Mandated by inspection agencies

Increase workstations

7.

Archiving and retrieval of specimens is a time consuming process that can be automated using stand-alone systems.

True

False

a.
