Final answer:
Immediate notification of the primary healthcare provider is warranted due to the critical changes in the renal system indicated by rising potassium, BUN, and creatinine levels, which suggest deteriorating renal function and potential hyperkalemia. 3. Pulmonary
Step-by-step explanation:
Critical changes in the renal system of a newly admitted client with multiple health issues require immediate notification of the primary healthcare provider. Analysis of the metabolic profile provided shows a progressive increase in potassium levels, from 4.2 mEq/L to 5.0 mEq/L, blood urea nitrogen (BUN) from 16 mg/dL to 22 mg/dL, and creatinine from 1.3 mg/dL to 2.0 mg/dL over the course of three days.
These changes suggest worsening renal function and the development of hyperkalemia, which can have serious cardiovascular consequences if not promptly managed. Additionally, the increase in BUN and creatinine suggests a decline in the kidneys' filtering capability, further validating the need for urgent intervention by the healthcare provider.
