The nurse is teaching a patient about the proper procedure for testing stool for occult blood. The nurse's teaching has been effective if the patient makes which statement?
a. "I apply a very thick smear of stool onto the guaiac slide.".
b. "The electronic meter calculates a reading within minutes.".
c. "It is best if I get two separate samples from the same stool.".
d. "I call my doctor for white paper with stool and developer on it.".
C
The patient is correct to say that more than one sample from the stool specimen is required for more conclusive results because occult blood from the gastrointestinal tract is not always equally dispersed through the stool. A thin smear is adequate for testing. An electronic meter is not used for guaiac testing. The stool is not placed on the paper until the patient is actually ready to test a sample.
