Editing Reduction of Risk Potential (section)

=== Other Common Preparations ===

* '''Barium studies''': after the study, give fluids and a laxative as ordered to prevent barium impaction, and tell the client that stools will be chalky white for a few days (Pagana et al., 2022).
* '''Tuberculin skin test''': inject intradermally to raise a wheal, do not massage, and read induration, not redness, at 48 to 72 hours (Pagana et al., 2022).
* '''Blood cultures''': draw before starting antibiotics whenever it does not delay treatment in sepsis, from two separate sites with strict aseptic technique (Potter et al., 2023).
* '''24-hour urine collection''': discard the first voiding, then collect all urine for the period, keep the specimen refrigerated or on ice as required, and end by having the client void at the exact final time and adding that specimen. A single discarded voiding invalidates the entire collection and it must restart (Pagana et al., 2022).
* '''Stool for occult blood''': depending on the test used, certain foods and drugs such as red meat, nonsteroidal anti-inflammatory drugs, and high-dose vitamin C may need to be withheld beforehand (Pagana et al., 2022).
