The nurse is teaching a NAP to test urine with a reagent strip for chemical properties. Which technique demonstrated by the NAP would indicate understanding of the process?
a. Immerse the reagent strip in urine for 1 minute.
b. Compare reagent strip to the color chart on the bottle.
c. Obtain the patient's first voided specimen in the morning.
d. Add a chemical tablet to the urine and then test with a reagent strip.
B
After immersing the reagent strip in the patient's urine and removing quickly, the nurse waits the exact number of seconds recommended before comparing the strip to the color chart on the bottle. The nurse avoids comparing the strip too early because the chemical reaction necessary to com-plete the test takes time to process. The first voided specimen of the day is frequently used for testing; however, the nurse obtains a urine specimen according to the provider's prescription. Reagent strips are one-step procedures.
