Question

19 multiple choice 5 points which substance is measured in urinary test as an indicator of kidney function? uric acid creatine creatinine potassium 20 multiple choice 5 points a blood test to detect ______ is routinely performed on infants. albumin acetones creatinine phenylketones

Explanation:

• For question 19: Creatinine is a waste product that is filtered by the kidneys. Measuring its level in urine helps assess kidney function. Uric acid is related to purine metabolism and can be associated with gout. Creatine is involved in energy metabolism in muscles. Potassium is an electrolyte regulated by the kidneys but is not the main indicator of kidney function in a urinary test like creatinine.
• For question 20: Phenylketonuria (PKU) is a genetic disorder. Infants are routinely tested for phenylketones in the blood. Albumin is a protein mainly tested in blood for liver and kidney function (but not a routine infant test for this). Acetones are tested in urine for conditions like diabetes ketoacidosis. Creatinine is for kidney function (not a routine infant test for this purpose).

Answer:

1. C. creatinine
2. D. phenylketones
