Gravity: 1.004/1.1017 pH: 5.5/7.0 Protein: Negative/Trace Glucose: Negative/Trace Blood: Negative/Trace. Microscopic: Rare epithelial cells/Occasional granular cast, Rare hyaline cast, Moderate epithelial cells. Which statement best explains these results? - The protein, glucose, and microscopic of A are falsely-negative because of the specific gravity. Urinalysis performed on a 27-year-old woman yields the following results: Sp. Gravity: 1.008 pH: 5.0 Protein: 2+ Glucose: Negative Ketones: Negative Bilirubin: Negative Blood: 3+ Nitrite: Negative Leukocytes: Positive Urobilinogen: 0.1 EU/dL WBC/HPF: 20-30 RBC/HPF: 30-55 Casts/LPF: Hyaline: 5-7 Red Cell: 2-5 Coarse Granular: 2-3 Waxy: 1-3 Uric Acid Crystals: Moderate Above data is consistent with: - Chronic renal disease. 52-year-old man has urine glucose measurements performed as part of a three (3) hour glucose tolerance test. Best explanation for these findings is that the: - Serum level must exceed the threshold level before reabsorption of glucose is exceeded.

Which of the following is the formula for calculating the gram equivalent weight of a chemical? - MW/Oxidation number. Serum protein electrophoresis pattern is consistent with: - Monoclonal gammopathy. ALP - Marked Increase ALT - Slight Increase AST - Slight Increase GGT - Marked Increase These results are most consistent with: - Obstructive Jaundice. A person suspected of having metabolic ALKALOSIS would have which of the following laboratory findings? - CO2 content AND pH elevated. What is the patient's Free Thyroxine Index? - 1.6. Which of the following is most likely to be ordered in addition to serum calcium to determine the cause of tetany? - Magnesium. A 9-month-old boy from Israel has gradually lost the ability to sit up and develops seizures. He has an increased amount of the phospholipid called Gm2-ganglioside in his neurons and he lacks the enzyme hexosaminidase A in his leukocytes. These findings suggest: - Tay-Sachs disease. An adult diabetic with renal complications has the following results: Sodium: 133 mEq/L BUN: 84 mg/dL Glucose: 487 mg/dL Creatinine: 5mg/dL Based off these results, the calculated serum osmolality is: - 304 mOsm/kg.

Arterial blood collection in a heparinized syringe but exposed to room air would cause which of the following changes in the specimen? - pO2: Elevated. pCO2: Decreased. pH: Elevated. A 50-year-old woman who has been receiving busulfan for three years for CML becomes anemic. Lab tests reveal: Thrombocytopenia, Many peroxidase-negative blast cells in the peripheral blood, Bone marrow hypercellular in blast transformation, Markedly increased bone marrow TdT. Which complication is this patient most likely experiencing? - Acute lymphocytic leukemia. Which is the most common cause of an abnormality in hemostasis? - Quantitative abnormality of platelets. A leukocyte count and differential on a 40-year-old Caucasian male reveals...this data represents: - Absolute neutropenia. A patient has a normal PTT and a prolonged APTT using a kaolin activator. The APTT corrects to normal when the incubation is increased. These results suggest the patient has: - Fletcher factor deficiency (prekallikrein.) Elevation of the TOTAL granulocyte count above 9.0 x 10^3/uL is termed: - Absolute neutrophilic leukocytosis.
