A nurse is performing discharge teaching with a client about the care of a newly created ileal conduit. The nurse should instruct the client to empty the appliance:

Choice A reason: Increased glomerular filtration rate (GFR) would indicate improved kidney function, which is not expected in the oliguric phase of acute kidney injury. Instead, GFR is typically reduced during this phase.
Choice B reason: Decreased creatinine level suggests better kidney function and is not consistent with acute kidney injury, where creatinine levels are usually elevated due to impaired filtration.
Choice C reason: Hypomagnesemia, or low magnesium levels, is not a typical finding in acute kidney injury. Electrolyte imbalances more commonly include elevated levels of potassium and phosphorus.
Choice D reason: Hyperkalemia, or elevated potassium levels, is a common finding in the oliguric phase of acute kidney injury due to the kidneys' inability to excrete potassium effectively. This can lead to serious complications such as cardiac arrhythmias.

Choice A reason: Cleaning the inside of the container with a wipe is not part of the standard procedure for collecting a midstream urine sample. The focus should be on maintaining external cleanliness to avoid contamination of the sample.
Choice B reason: Urinating a little then stopping is part of the process, but this statement alone does not indicate a complete understanding of the procedure. The critical aspect is how the client cleans and collects the sample to ensure it is not contaminated.
Choice C reason: Using the cleansing wipe from front to back is the correct procedure for collecting a midstream urine sample. This method helps prevent contamination from bacteria that could be present around the genital area, ensuring a more accurate sample for analysis.
Choice D reason: Using each cleansing wipe twice is not advised as it can lead to contamination. Each wipe should be used only once to maintain hygiene and ensure the accuracy of the urine sample.
