Final answer:
The lab test that may impact the decision to administer IV contrast media is creatinine. Creatinine is a waste product produced by muscles and excreted through the kidneys. Elevated levels of creatinine in the blood can indicate impaired kidney function.
Step-by-step explanation:
The lab test that may impact the decision to administer IV contrast media is creatinine.
Creatinine is a waste product that is produced by muscles and excreted through the kidneys. Elevated levels of creatinine in the blood can indicate impaired kidney function. IV contrast media can put additional strain on the kidneys, so if a patient has high levels of creatinine, the decision to administer IV contrast media may need to be reevaluated.
The other lab tests mentioned, BUN (blood urea nitrogen) and PT (prothrombin time), are not directly related to the decision to administer IV contrast media. BUN measures the amount of urea nitrogen in the blood and PT measures how long it takes for blood to clot, both of which provide different information about a patient's health.
