A 55-year-old client is provided with a multi-card guaiac-based fecal occult blood test (gFOBT) kit during an annual wellness exam for colorectal cancer screening. The nurse provides step-by-step instructions for completing the screening at home. Arrange the following actions in the correct chronological sequence the client must follow.
- 1Discontinue the intake of vitamin C supplements, red meat, and raw vegetables 72 hours prior to the test.
- 2Collect the stool specimen in a clean, dry container, ensuring it does not mix with urine or toilet water.
- 3Use the provided wooden applicator to gather a small sample from one area of the stool and smear it onto the first window of the test card.
- 4Use the opposite end of the applicator to collect a second sample from a different area of the same stool and smear it onto the second window.
- 5Close the protective cover flap over the test windows and return the completed cards to the clinic within the specified timeframe.
Answer
The correct chronological sequence for an at-home gFOBT is: dietary preparation, uncontaminated stool collection, first stool smear, second stool smear from a different area, and finally securing and returning the card.
The correct sequence follows the evidence-based progression of patient preparation, specimen collection, specimen application, and handling for a screening gFOBT. Dietary restrictions must be implemented 72 hours before collection. Uncontaminated collection must precede application. The first smear is taken, followed immediately by a second smear from a completely different area of the same stool using the opposite end of the applicator. This maximizes the detection of unevenly distributed blood. Finally, the card is secured and returned within the laboratory's required timeframe.
