One of the primary functions of the kidneys is to filter waste products from the blood, including blood urea nitrogen (BUN) and creatinine. Therefore, as kidney function deteriorates, the levels of these waste products in the blood typically increase.<\/p>\n\n\n\n<p><strong>BUN (Blood Urea Nitrogen):<\/strong> BUN is a measure of the amount of nitrogen in the blood that comes from the urea, a waste product formed from the breakdown of proteins. In normal kidney function, BUN levels are kept within a certain range. Elevated BUN levels can indicate impaired kidney function, dehydration, or increased protein breakdown. For an adult with CKD, BUN levels are often significantly elevated due to reduced kidney filtering capability. A normal BUN range is generally between 7 to 20 mg\/dL. Values exceeding 40 mg\/dL, such as 45 mg\/dL, suggest advanced CKD or significant impairment.<\/p>\n\n\n\n<p><strong>Creatinine:<\/strong> Creatinine is a byproduct of muscle metabolism, and its levels are relatively stable in the blood. The kidneys normally filter creatinine out of the blood and excrete it in urine. Elevated creatinine levels indicate that the kidneys are not functioning properly. The normal range for serum creatinine is approximately 0.6 to 1.2 mg\/dL. In CKD, creatinine levels rise significantly as kidney function declines. A creatinine level of 8 mg\/dL is indicative of severe renal impairment or end-stage renal disease.<\/p>\n\n\n\n<p><strong>Interpretation of Other Choices:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B:<\/strong> A BUN of 8 mg\/dL and creatinine of 0.7 mg\/dL reflect normal kidney function and would be expected in a healthy individual or someone with well-managed kidney conditions.<\/li>\n\n\n\n<li><strong>C:<\/strong> A BUN of 10 mg\/dL and creatinine of 0.3 mg\/dL are also within normal ranges and do not suggest significant kidney impairment.<\/li>\n\n\n\n<li><strong>D:<\/strong> A BUN of 23 mg\/dL and creatinine of 1.0 mg\/dL, while slightly elevated for BUN, are still within relatively normal ranges for creatinine. This would not be indicative of advanced CKD.<\/li>\n<\/ul>\n\n\n\n<p>In summary, for a client with chronic kidney disease, elevated levels of both BUN and creatinine are expected findings, reflecting the reduced filtering capacity of the kidneys. Thus, option A with BUN 45 mg\/dL and creatinine 8 mg\/dL best aligns with the anticipated lab results in severe CKD.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A nurse is reviewing the BUN and creatinine levels of an older adult client who has chronic kidney disease.
