A 50-year-old female patient presents to the emergency department with severe left flank pain radiating to the groin. CT scan reveals a 6mm calcium oxalate stone in the left ureter. The patient has a history of recurrent kidney stones. Which nursing intervention should be the highest priority?
1Administer prescribed analgesics and monitor pain relief
2Encourage increased fluid intake to promote stone passage
3Strain all urine and monitor for stone fragments
4Assess for signs of urinary obstruction and infection✓ 정답
해설
Assessing for urinary obstruction and infection is highest priority as these are life-threatening complications requiring immediate intervention. Pain management, fluid intake, and straining urine are important but secondary to identifying emergencies.
Core Nursing ExplanationKey Concept Analysis: This question tests the ability to prioritize nursing interventions for a patient with a Ureteral stone (Urolithiasis). The core principle is Maslow's Hierarchy of Needs and the ABCs (Airway, Breathing, Circulation) of prioritization. While pain is severe and distressing, potential complications that threaten organ function or lead to systemic infection (sepsis) take precedence. A stone causing complete obstruction can lead to Hydronephrosis (kidney swelling), permanent kidney damage, and Pyelonephritis (kidney infection) which can progress to urosepsis.
Answer Rationale: Key Point! Option ④ is correct because it represents a systematic assessment for life-threatening complications. The nurse must first assess for signs of Urinary obstruction (e.g., anuria, severe flank pain, nausea/vomiting) and Infection (e.g., fever, chills, cloudy/foul-smelling urine, elevated WBC count). Identifying these complications early is critical to prevent permanent kidney damage and sepsis, which aligns with the safety and physiological integrity needs at the base of Maslow's pyramid.
Distractor Analysis:
Watch out for confusion! Option ① (Administer analgesics) addresses the patient's immediate comfort and is a very important intervention, but patient safety (assessing for threats to organ function) always comes before comfort. Pain management is a high-priority comfort measure but not the highest priority when potential physiological threats exist.
Option ② (Encourage fluids) is a key therapeutic measure to help flush the stone, but it should only be encouraged after confirming there is no complete obstruction. Forcing fluids in the presence of a complete blockage could increase pressure in the renal pelvis and worsen pain or injury.
Option ③ (Strain urine) is an important diagnostic and safety measure to collect the stone for analysis, but it is a monitoring activity, not an immediate life-saving assessment. It is implemented after addressing acute threats.
Related Concepts: The nursing process dictates Assessment always comes first. You cannot plan or implement effective care (like pain meds or fluid therapy) without first fully assessing the patient's status for potential emergencies. Also recall that for any condition involving a hollow organ (ureter, intestine, bile duct), obstruction and its consequences (ischemia, rupture, infection proximal to the blockage) are always high-priority concerns.
Severe, colicky pain is a hallmark. NSAIDs (e.g., Ketorolac) and opioids are used. Important but secondary to assessing for obstruction/infection.
Comfort need, high but not highest priority.
Conservative Stone Management
Fluids (2-3L/day), strain urine, analgesics, ambulation. Contraindicated if complete obstruction or active infection present.
Therapeutic measures applied after initial assessment.
Side-by-Side Comparison!
Priority Intervention (Correct)
Important but Secondary Interventions (Distractors)
Assess for obstruction/infection: Check urine output, vital signs (fever), symptoms (chills, nausea). This identifies immediate threats to life and organ function.
Administer analgesics: Manages symptom (pain) but does not treat the cause or identify complications.
Rationale: Prevents permanent kidney damage and sepsis. This is a surveillance and safety action.
Rationale: Provides comfort and allows for other interventions (e.g., ambulation). This is a symptom management action.
Pathophysiology: A stone lodged in the ureter obstructs urine flow from the kidney to the bladder. This increases pressure in the renal pelvis (Hydronephrosis), impairing glomerular filtration and potentially causing ischemic damage to nephrons. Stagnant urine is a perfect medium for bacterial growth, leading to infection.
Stone Composition: Calcium oxalate stones (most common) are radiopaque and visible on X-ray/CT. Knowing the type guides long-term prevention (e.g., dietary oxalate restriction, thiazide diuretics).
Pharmacology for Renal Colic: First-line is often NSAIDs (Ketorolac) which reduce prostaglandin-mediated ureteral inflammation and pain. Opioids (Morphine) may be added for severe pain. Antispasmodics (e.g., Tamsulosin) are sometimes used to relax ureteral smooth muscle.
Memory Tips
Acronym: PASS the Stone: Priority? Assess for Obstruction/Infection first. Second, give meds for Severe pain. Then, Teach fluids & straining.
Think "HOLE": Any Hollow organ Obstruction (Life-threatening) Emergency assessment first! (Applies to bowel, bile duct, ureter).
High-Frequency NCLEX Topics
NCLEX loves testing prioritization and delegation. A classic pattern is presenting a patient with a painful condition (renal colic, pancreatitis, fracture) and asking for the "first," "initial," or "priority" action. The correct answer is almost always the one that involves assessment for complications (bleeding, obstruction, infection, neurological deficit) over comfort measures or routine procedures. Remember: Assess before you act.
Watch Out for Question Variations!
Variation 1 (Shift to Implementation): "The nurse has assessed the patient and finds no signs of obstruction or infection. Which intervention should the nurse implement next?" Answer: Likely administer prescribed analgesics, as pain relief is now the next priority.
Variation 2 (Shift to Patient Education): "The patient's stone has passed. Which teaching is most important for preventing recurrence?" Answer: Focus on increasing fluid intake to maintain dilute urine.
Variation 3 (Lab Value Focus): The question might provide lab results like elevated WBC and Serum Creatinine, making the priority assessment for infection/obstruction even more obvious.
Nursing Clinical Practice GuideClinical Scenario: You are the nurse in the ED. Mrs. Johnson, 50, is curled on the stretcher, pale, diaphoretic, and rates her left flank pain as 10/10. She states the pain comes in waves and radiates "down to my private area." She has a history of two prior kidney stones. Her vital signs are: BP 150/90, HR 112, RR 24, Temp 37.8°C (100°F). She has not urinated since the pain started 4 hours ago.
Nursing Intervention Strategy:
Immediate Assessment (Priority):
Urinary Output: Ask about last void. Palpate bladder for distension. If an indwelling catheter is placed, monitor output closely. Oliguria (<30mL/hr) or anuria is a red flag.
Signs of Infection: Re-assess temperature. Ask about chills, dysuria, or cloudy/foul-smelling urine. Review pending lab work (Urinalysis for WBC, nitrites; CBC for elevated WBC count).
Pain Assessment: Use PQRST (Provocation, Quality, Region, Severity, Time) to characterize the pain, but do not let pain assessment delay looking for obstruction/infection.
Vital Sign Trends: Rising temperature, tachycardia, and tachypnea may indicate developing sepsis.
Collaborative Care & Monitoring:
After initial assessment, administer prescribed analgesics promptly (often IV Ketorolac and/or Morphine).
Once obstruction/infection is ruled out, encourage PO/IV fluids aggressively (e.g., 150-200 mL/hr if tolerated) to promote diuresis and stone passage.
Provide a urine strainer and instruct the patient to void all urine through it. Save any gravel or stones for lab analysis.
Encourage ambulation if pain is controlled, as gravity can aid stone movement.
Patient Education & Discharge Planning:
Teach lifelong prevention: Fluid goal of 2-3 L/day to produce at least 2L of urine daily.
Discuss dietary modifications based on stone type (e.g., for calcium oxalate: limit spinach, nuts, chocolate; moderate sodium and animal protein).
Explain signs of complications to report: fever, uncontrolled pain, inability to urinate.
Patient Safety and Precautions:
Contraindication for Fluids: Do not aggressively push oral fluids if the patient is nauseated/vomiting or if complete obstruction is suspected. IV fluids may be used instead.
Medication Caution: NSAIDs like Ketorolac are contraindicated in patients with renal impairment or peptic ulcer disease. Monitor for GI upset and renal function.
Monitoring for Stone Passage: The most common time for a stone to pass is when the patient is relaxing (e.g., at night). Sudden relief of pain followed by urinary urgency may indicate passage.
Nursing Procedure & Medication FlowProcedure: Assisting with Urine Straining
1. Provide patient with a clean urine strainer (fine-mesh) and a clean collection cup.
2. Instruct patient to urinate directly into the strainer placed over the toilet or collection cup.
3. After voiding, examine the strainer for any particles, sand, or stones.
4. Transfer any material to a labeled specimen container for lab analysis.
5. Document the presence/absence of particles and patient education provided.
Medication: IV Ketorolac (Toradol) Administration
Action: Nonsteroidal anti-inflammatory drug (NSAID). Reduces inflammation and prostaglandin synthesis in the ureter.
Dose & Route: Typical initial dose is 30 mg IV over 15-30 seconds.
Key Monitoring: Pain relief (re-assess in 30 min). Monitor for GI distress, bleeding, and renal function (urine output, BUN/Creatinine).
Precaution: Limited to short-term use (usually ≤5 days) due to side effect risk.
A Word from Your Senior Nurse
"In the hustle of a busy ED, a patient with 10/10 pain naturally draws your instinct to reach for the pain meds first. But take that crucial extra minute. Ask about urine output. Feel for a fever. Look at the heart rate. That quick assessment for obstruction or infection isn't just a test answer—it's what separates a task-completer from a true patient advocate. Catching early urosepsis can save a kidney, and even a life. When you study, drill this prioritization mindset: 'What can kill or maim my patient first?' That's the NCLEX's favorite question, and more importantly, it's your patient's most critical need."
Hydronephrosis — Swelling of the kidney due to a buildup of urine caused by an obstruction in the urinary tract (e.g., a stone). Can lead to kidney damage if not relieved.
Pyelonephritis — A type of urinary tract infection (UTI) that has reached and inflamed the kidney tissue. Often presents with fever, chills, flank pain, and can be a complication of an obstructing stone.
Renal Colic — The severe, intermittent, cramping pain typically caused by a kidney stone moving through and obstructing the ureter. Pain often radiates from the flank to the groin.
Urolithiasis — The medical term for the process of forming stones (calculi) in the kidney, bladder, and/or urethra. Kidney stones are also called renal calculi.
Oliguria — Low urine output, clinically defined as less than 400 mL per day or less than 0.5 mL/kg/hr in adults. A key sign of potential urinary obstruction or renal impairment.
