An elevated creatinine value is most likely to be accompanied by which other value?

An elevated creatinine value is often indicative of impaired kidney function, as creatinine is a waste product generated from muscle metabolism and is primarily eliminated from the body through the kidneys. When kidney function declines, the kidneys are less efficient at clearing both creatinine and other nitrogenous waste products from the bloodstream.

In these cases, blood urea nitrogen (BUN) levels typically rise along with creatinine levels. The relationship between BUN and creatinine is particularly important in clinical assessments of renal health. A concurrent elevation in both BUN and creatinine suggests that the kidneys are not adequately filtering these substances, which is common in conditions affecting renal function such as acute kidney injury or chronic kidney disease.

The other options do not typically correlate with an elevated creatinine level in the context of impaired renal function. A reduced glucose level does not have a direct connection to creatinine levels, as glucose metabolism is largely independent of renal excretory capability. Normal electrolyte levels might occur but are not guaranteed in the context of elevated creatinine, given the kidney’s role in regulating electrolytes. Furthermore, decreased proteinuria would suggest less protein is spilling into the urine and is less relevant to the scenario of elevated creatinine due to compromised renal function.
