What is one criteria for administering Fentanyl to a kidney stone patient?

Administering Fentanyl to a kidney stone patient is generally guided by their pain management needs, particularly since kidney stones are known to cause significant and acute pain. A prior history of kidney stones serves as an important criterion because it indicates that the patient is familiar with the type of pain associated with this condition. This knowledge can help assess the patient's pain level and confirm that it is likely related to the kidney stones rather than other potential causes of acute abdominal pain.

Additionally, a patient with a prior history is more likely to have experienced similar symptoms before, making them a more reliable source for reporting the intensity and characteristics of their pain. This understanding aids in determining the necessity and appropriateness of administering Fentanyl as part of pain management.

In contrast, the other options—age, fever, and a history of chronic pain—do not specifically correlate with the acute management of kidney stone pain and would not directly influence the decision to administer Fentanyl in this scenario.
