A 40-year-old male presents with sudden onset of severe, colicky right flank pain radiating to his groin. He reports recent nausea and vomiting. He is pacing restlessly and unable to find a comfortable position. His vital signs are BP 140/90 mmHg, HR 100 bpm, RR 18 bpm. Which of the following is the most appropriate initial intervention?
- AAdminister oral antiemetics to control nausea.
- BInitiate IV access and administer analgesics.
- CPrepare for immediate surgical intervention.
- DAdminister a fluid bolus to increase renal perfusion.
Show answer & explanationAnswer & explanation
Correct answer: B. Initiate IV access and administer analgesics.
The patient's symptoms (sudden onset severe, colicky flank pain radiating to the groin, nausea/vomiting, restlessness) are classic for renal colic, typically caused by kidney stones. While definitive treatment involves stone passage or removal, the immediate prehospital priority is pain management due to the excruciating nature of the pain. IV access is necessary for administering effective analgesics and antiemetics.
Why the other options are wrong
- A. Oral antiemetics are insufficient for severe pain and may not be retained due to vomiting; IV antiemetics are better, but pain control is the primary concern.
- C. Immediate surgical intervention is not a prehospital capability and is only considered after hospital evaluation if conservative measures fail or complications arise.
- D. While hydration is important, a fluid bolus is not the primary intervention for pain relief in renal colic, and excessive fluids can sometimes worsen pain by increasing renal pressure.
Renal Colic Management
Management of renal colic (kidney stone pain) in the prehospital setting focuses on aggressive pain control and antiemetics, typically via IV, as the pain is often severe and associated with nausea/vomiting.
- Characterized by sudden, severe, colicky flank pain radiating to groin.
- Nausea and vomiting are common.
- Pain management is the immediate priority.
- NSAIDs and opioids are common analgesic choices.
