Final answer:
The priority lab finding to report for a client on ceftazidime is an increased creatinine level, which may indicate renal impairment or failure. Other findings like liver enzymes, platelet count, and hemoglobin levels are also important but less directly related to ceftazidime's common adverse effects.
Step-by-step explanation:
When reviewing lab results for a client receiving ceftazidime via IV bolus, the priority lab finding to report to the provider would be c. Increased creatinine level. This is because ceftazidime, an antibiotic, is primarily excreted by the kidneys, and an increased creatinine level could indicate renal impairment or failure, which is a serious and potentially life-threatening condition. Although elevated liver enzymes, decreased platelet count, and low hemoglobin levels are significant findings that should be monitored, they do not directly relate to the common adverse effects of ceftazidime as much as the changes in renal function do.
