Nursing Clinical Practice Guide
Clinical Scenario: You are the triage nurse in the Emergency Department. A 45-year-old construction worker is brought in by his coworkers, doubled over in pain. He is diaphoretic (sweaty), pale, and constantly shifting position on the gurney, unable to get comfortable. He states, "It feels like something is tearing in my side and going down to my...you know...my privates." He has vomited twice in the ambulance.
Nursing Intervention Strategy
1. Immediate Assessment (ABCs with a pain focus):
* Airway/Breathing: Ensure patent. Pain can cause rapid, shallow breathing.
* Circulation: Obtain vital signs. Tachycardia and hypertension are common due to pain.
* Pain (The "P" in your focused assessment): Use PQRST or OLDCARTS. Critically document: Onset (sudden), Location (point to where it starts and where it goes), Character ("colicky," "cramping," "waves"), Radiation (flank to groin), Severity (use 0-10 scale), and Timing (constant vs. intermittent). This documentation is crucial for diagnosis.
* Assess for CVA tenderness by fist percussion.
2. Priority Actions:
* Establish IV access for fluids and medication administration.
* Administer prescribed analgesics (often IV NSAID first, then opioid if needed) promptly. Pain control is a priority and aids diagnosis by allowing the patient to cooperate with exams.
* Obtain urine specimen for urinalysis (to check for Hematuria) and culture if infection is suspected.
* Provide an emesis basin and antiemetics as needed.
3. Ongoing Care & Monitoring:
* Encourage ambulation if possible, as gravity may help stone passage.
* Strain All Urine! Provide a urine strainer and instruct the client to void through it. Any passed gravel or stone must be saved in a container for lab analysis to determine stone composition.
* Monitor intake and output. Encourage oral fluids once nausea subsides to promote diuresis and stone passage.
* Assess for signs of complications: worsening pain, fever (suggests infection proximal to obstruction), anuria (suggests complete bilateral obstruction or solitary kidney obstruction – a urologic emergency!).
Patient Safety and Precautions
* Medication Caution: NSAIDs are contraindicated in patients with renal impairment or peptic ulcer disease. Opioids require monitoring for sedation and respiratory depression.
* Contrast Dye: If a CT with contrast or an IVP (Intravenous pyelogram) is ordered, verify renal function (BUN, Creatinine) and check for allergies to iodine/contrast media.
* Infection Risk: Obstruction + infection = Obstructive pyelonephritis, which is a urologic emergency requiring urgent drainage (e.g., stent or nephrostomy tube).
Nursing Procedure & Medication Flow
Procedure: Assisting with Urine Straining
1. Explain the purpose: "We need to catch any small pieces of the stone to find out what it's made of. This helps us give you the right advice to prevent future stones."
2. Provide a clean urine strainer (fine-mesh) placed over a specimen cup or hat placed in the toilet.
3. Instruct the client to void all urine through the strainer.
4. After voiding, examine the strainer for any particles. Use a tongue depressor to transfer any material to a labeled specimen container.
5. Send to the lab per protocol.
Medication: IV Ketorolac (Toradol) Administration
* Class: NSAID (Nonsteroidal anti-inflammatory drug).
* Action: Reduces prostaglandin synthesis, decreasing inflammation and ureteral edema, which can relieve pain and facilitate stone passage.
* Dose & Route: Typical dose 15-30 mg IV. Onset is within 30 minutes.
* Key Monitoring: Assess for GI upset, monitor renal function (especially in dehydrated patients), and watch for signs of bleeding. Do not use for more than 5 days.
A Word from Your Senior Nurse
"In the chaos of the ED, a patient with renal colic can be one of the most visibly distressed. Your calm, efficient assessment and rapid pain management are therapeutic in themselves. Remember, their restlessness is a key diagnostic clue – don't mistake it for 'drug-seeking' behavior. That classic pain story – 'sudden, worst pain of my life, from my back to my groin' – is one you'll hear and recognize instantly. Mastering these classic presentations builds your clinical intuition, making you a faster, more confident nurse. Always connect the dots: the anatomy (ureter), the physiology (spasm), and the clinical picture (colicky pain, restlessness). That's how you move from memorizing to truly understanding nursing care."
