Ch 10 & 11 Review
| Question | Answer |
|---|---|
| Creatinine measurement is used in nutritional nutritional assessment to assess the _____ of the body. | Total Body Muscle Mass |
| A high level of retinol-binding protein correlates most closely w/a finding of: | Normal conditions of nourishment & nutrition. |
| The patient has severe steatorrhea. The most likely vitamin deficiency that may accompany this condition is: | B12 def |
| Deficiencies of this vitamin are associated w/prolonged prothrombin time (>15 seconds) and coagulation disorders is: | Vitamin K |
| Wilson's disease is characterized by toxic levels of: | Copper |
| Zinc deficiency is associated with: | Night blindness & poor wound healing |
| Megaloblastic anemia is common in alcoholics, or in pregnancy if no vitamin supplements & poor diet are present. Which lab findings correlate w/this condition? | B12 deficiency & folate |
| Cystic fibrosis is associated with: | pancreatic insufficiency, Decreased amylase, lipase, bicarbonate, & pancreatic exocrine function, & fecal fat |
| Vitamin B12 may be indirectly assessed by: | methomelonic acid (mma) homosistine |
| The basis of the lactose breath test is: | The production of Hydrogen (H2) by bacterial fermentation of carbohydrate substrate in the colon. |
| When ion tophoresis is used to collect sweat, pilocarpine is used to: | facilitate sweating |
| The CLS noted a flagged alb low by the auto chem analyzer. Upon examination, the CLS found the specimen number matched that of a 70-yr-old femal. The blood had been drawn 2 hrs before & was slightly hemolyzed. The CLS did not xplore the result further: | She was older |
| Fluorescent polarization immunoassay is a good alternative to radioimmunoassay for analysis of thyroxine because it: | Good sensitizing & specificity, moderate complexity, fewer safety regulations |
| Peroxidase-labeled antibody binds w/patient thyroxine to form a complex. Addition of luminol substrate forms an oxidized product that emits light for short time measured by a luminometer. This describes: | Chemiluminescence |
| Primary hypercortisolism is associated w: | Decreased ACTH, Increased cortisol, & loss of diurnal variation |
| A patient w/increased aldosterone & renin levels most likely has: | Secondary hyperaldosteronism |
| A young male w/acromegaly has been found to have a pituitary aldenoma that secretes growth hormone. This is correlated w: | Secondary giantism |
| The clinical lab scientist instructed the patient to collect a 24-hr urine collection for VMA. The CLS asked the patient to restrict dietary consumption of: | Coffee, bananas, vanilla, citrus, aspirin, anti hyper drugs |
