In cases of renal colic, what should be avoided in terms of pain medication?

  1. Ketorolac

  2. Ibuprofen

  3. Acetaminophen

  4. Morphine

The correct answer is: Ketorolac

In cases of renal colic, it is important to avoid certain pain medications that can exacerbate the condition or pose risks to the patient. Ketorolac, a non-steroidal anti-inflammatory drug (NSAID), is typically avoided because it has a stronger anti-inflammatory effect and can affect renal function. This is particularly concerning in patients who may already be experiencing compromised renal perfusion due to obstruction caused by kidney stones. Using medications that can influence kidney function or cause further irritation to the renal system is not advisable, as they may increase the risk of adverse effects or hinder the resolution of the underlying issue. In contrast, other pain management options such as acetaminophen or morphine may be more appropriate as they do not carry the same risk of impacting kidney function negatively in the context of renal colic.
