A hemolyzed specimen is received in the laboratory for enzyme analysis. The assay for which of the following enzyme values would be affected by hemolysis?
A) -glutamyl transferase (GGT)
B) Lipase
C) Creatine kinase
D) Amylase
Question 2
During a state of low blood volume and decreased extracellular sodium level (as in cardiac failure), which one of the following occurs?
A) Renin is produced by the kidneys and is converted to angiotensin, which induces the secretion of aldosterone by the adrenal gland, which in turn increases reabsorption of sodium and retention of water.
B) Aldosterone is produced by the kidneys, leading to the release of renin, which increases kidney reabsorption of sodium.
C) Renin is produced by the adrenal glands, leading to vasoconstriction and production of antidiuretic hormone by the pituitary gland, which increases fluid volume by causing water retention.
D) Antidiuretic hormone produced by the kidneys stimulates the production of aldosterone by the adrenal gland, which increases reabsorption of sodium and water retention.
