Final answer:
The statement indicating a need for more teaching is "I will keep the toilet paper in the specimen," as this could contaminate the urine sample, which should be avoided for a routine urinalysis.
Step-by-step explanation:
The statement that indicates a need for more teaching is "C) "I will keep the toilet paper in the specimen."". When collecting a specimen for a routine urinalysis, it is essential that the specimen not be contaminated. This includes ensuring no toilet paper, stool, or, for women on their menstrual cycle, menstrual blood contaminates the urine sample. The correct procedure involves a clean catch; the patient should wash the genital area and then begin to urinate, letting some urine fall into the toilet before catching the rest in the specimen container.
Mentioning the menstrual period, as in statement A, is also important because it may affect the analysis if contamination occurs. Statement B is correct, and statement D reflects proper understanding to avoid stool contamination.
