Manitoba Nephrology Nurse Practice Test

The indications for a kidney biopsy include instances where there is an unexplained decrease in kidney function. This procedure is often performed when there is a need to gather more information about potential underlying kidney diseases or conditions that are not clearly diagnosed through other means. A decrease in kidney function can signal a range of problems, including glomerulonephritis, interstitial nephritis, or various systemic diseases affecting the kidneys. A biopsy allows for direct examination of kidney tissue, which can help in establishing an accurate diagnosis, guiding treatment options, and predicting patient outcomes.

In contrast, general health maintenance does not necessitate a biopsy, as this procedure is specific to diagnosing renal issues rather than routine assessment. Routine screening of all patients is not appropriate, as biopsies carry risks and are reserved for specific clinical situations. While patient preference may play a role in decision-making, it does not serve as a standard medical indication for conducting a kidney biopsy without other clinically relevant factors. Thus, the focus remains on unresolved kidney function issues, making it the primary indication for this invasive diagnostic procedure.
