What is a necessary monitoring aspect for a patient on ketorolac?

Monitoring renal function is essential for a patient receiving ketorolac because this medication, a nonsteroidal anti-inflammatory drug (NSAID), can affect kidney function. Ketorolac can potentially cause renal impairment, particularly in patients who are dehydrated, have pre-existing renal conditions, or are taking other medications that can stress the kidneys. Monitoring renal function allows healthcare providers to detect any changes in serum creatinine levels or glomerular filtration rates, ensuring that the patient is not at increased risk for complications like acute kidney injury.

The other aspects like daily weight, liver function tests, and cardiac rhythm are not primary concerns associated with ketorolac therapy. Daily weight monitoring may be relevant for medications that cause fluid retention, liver function tests are more pertinent to medications known to cause liver toxicity, and cardiac rhythm monitoring is typically associated with drugs that can affect cardiac function, none of which directly apply to the primary concerns surrounding ketorolac usage.
