• Question 34:

  Joint pain is a common early symptom of HH. Cirrhosis of the liver, cardiomyopathy, and diabetes are late symptoms of HH. What is a common early symptom of hereditary hemochromatosis (HH)?

  A. Joint pain

  B. Cirrhosis of the liver

  C. Diabetes

• Question 35:

  Darkfield microscopy allows a lower limit of resolution than bright-field microscopy which helps the tiny spirochetes to be seen in patient samples. In darkfield microscpy, there is a dark background where directly transmitted light is excluded by a dark-field condenser allowing only scattered light to be focused on the specimen. With dark-field microscopy bacteria appear luminous against a dark background.

  Which of the following microscopic techniques is best suited for direct examination of the infectious agent of syphilis?

  A. Light microscopy

  B. Phase microscopy

  C. Darkfield microscopy

  D. Electron microscopy

  Correct Answer: C

• Question 36:

  Whole blood glucose values are lower than plasma glucose values. For this reason, point- of-care whole blood glucose meters are programmed to correct the value before presenting the result; therefore, the whole blood glucose meter result correlates to serum or plasma results.

  Whole blood glucose values are ____________ plasma glucose values.

  A. Greater than

  B. Lower than

  C. Equal to

  Correct Answer: B

• Question 37:

  Macroamylasemia can be diagnosed by measuring amylase levels in the urine and serum. In patients with macroamylasemia, there will be high levels of amylase in the serum. However, macroamylasemia can look similar to acute pancreatitis, which also causes high levels of amylase in the blood. To help differentiate, we measure amylase levels in the urine. Urine levels of amylase are low in people with macroamylasemia, but high in patients with pancreatitis.

  The results which would be MOST consistent with macro-amylasemia are?

  A. Normal serum amylase and elevated urine amylase values

  B. Increased serum amylase and normal to low urine amylase values

  C. Increased serum and increased urine amylase values

  D. Normal serum and normal urine amylase values

  Correct Answer: B

• Question 38:

  In sickle cell anemia, rapid hemoglobin turnover may be present. HbA1C and other glycated hemoglobin assays are not valid in rapid hemoglobin turnover and in abnormal hemoglobin conditions. Fructosamine measurements can be used because of shorter half life of albumin.

  HbA1C measurements are NOT ordinarily used to monitor long-term diabetic control in a diabetic with sickle cell anemia.

  A. true

  B. false

  Correct Answer: A

• Question 39:

  The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and a swollen vesicle in a fungus culture are excellent clues indicative of Aspergillus. Aspergillus has the ability to infect primarily immunocompromised hosts, and causes pneumonia and/or disseminates to other organs. Clinical specimens should be inoculated onto primary isolation media, such as Sabouraud's dextrose agar. Aspergillus spp. are fast growing and can be white, yellow, yellow-brown, brown to black or green in color.

  The presence of hyaline, septate hyphae, and a young conidiophore with a foot cell and a swollen vesicle in a fungus culture are excellent clues indicative of:

  A. Acremonium

  B. Aspergillus

  C. Paecilomyces

  D. Penicillium

  E. Scopulariopsis

  Correct Answer: B

• Question 40:

  A. medical technologist

  B. medical laboratory scientist

  C. medical technician

  D. medical laboratory technician

  Correct Answer: B
