Step-by-step explanation:
The most likely explanation for the BMP results of the unconscious 69-year-old male is acute kidney injury (AKI). AKI is a condition characterized by a sudden loss of kidney function, leading to an increase in waste products like urea and creatinine in the blood. The elevated BUN (35 mg/dL) and creatinine (1.2 mg/dL) levels indicate impaired kidney function. Additionally, the high sodium (Na) level (150 mEq/L) may be a result of the kidney's inability to regulate electrolyte balance.
