1. An elderly patient (GFR 28 mL/min) becomes agitated after propofol sedation for fracture reduction. Which medication-related factor requires immediate reassessment?
Answer: D
Renal impairment prolongs midazolam elimination (half-life up to 40 hrs vs. 2-6 hrs normal), causing delayed emergence agitation. Propofol clears rapidly, making midazolam the likely culprit per Beers Criteria. Opioids (A) and diphenhydramine (C) have shorter durations. Lidocaine (B) doesn't cause agitation.
2. During a network outage, a nurse discovers an unlabeled unit-dose medication beside a patient's bed. The patient has renal impairment and multiple medication allergies. What should the nurse do first?
Answer: B
Unlabeled medications pose immediate safety risks, especially with allergies and renal issues (Joint Commission NPSG). Discarding prevents potential harm and complies with medication safety protocols. Option A is unsafe without electronic MAR verification during downtime. Option C delays necessary treatments and ignores that some medications are time-critical. Option D risks misidentification since printed references can't confirm patient-specific orders. The renal impairment and allergy history heighten vulnerability to errors, making disposal the safest initial action.
3. A medical-surgical unit aims to reduce catheter-associated urinary tract infections (CAUTIs). The team notes inconsistent documentation of catheter necessity during multidisciplinary rounds and variable nurse-driven removal protocols. Which project management approach best addresses these workflow and documentation gaps?
Answer: A
Daily huddles with checklists integrate real-time workflow assessment (cue: inconsistent documentation during rounds) and protocol standardization (cue: variable removal practices), enabling immediate corrective action. Option B lacks sustainability for workflow gaps. Option C addresses documentation but not protocol variability. Option D audits but doesn't prevent errors proactively. Daily interventions align with IHI's real-time quality improvement models for dynamic care processes.
4. During a home health visit, a nurse assesses a patient with end-stage renal disease receiving hemodialysis. The patient reports nausea and fatigue. Physical exam reveals temporal wasting, mild edema, and a body mass index (BMI) of 19. Which risk factor contributes most significantly to this patient's malnutrition?
Answer: D
Hemodialysis increases protein catabolism and nutrient losses, directly causing malnutrition in ESRD per NKF guidelines. Edema (A) may reflect fluid shifts, not causation. BMI 19 (B) is a sign, not a risk factor. Nausea/fatigue (C) are symptoms but less specific than dialysis-related metabolic demands. The regimen drives hypermetabolism and anorexia, making it the primary modifiable risk.
5. When preparing to administer IV vancomycin to a patient with difficult venous access, which factor poses the GREATEST risk for potential extravasation injury requiring specific management?
Answer: C
Vancomycin is classified as an irritant that can cause significant tissue damage if extravasated. A small-gauge (22G) catheter in a fragile hand vein significantly increases the risk of infiltration/extravasation and the potential severity due to limited tissue space (Cue: Catheter size/location, drug irritant potential). Option A (rash) relates to hypersensitivity, not extravasation risk. Option B (duration) is standard and doesn't inherently increase extravasation risk if IV is patent. Option D (creatinine) relates to renal dosing/monitoring, not extravasation mechanics.
6. A medical-surgical nurse seeks primary evidence about heparin dosing in obese patients with renal impairment after discovering conflicting guidelines. Which source represents the strongest evidence for practice change?
Answer: B
Meta-analyses of RCTs provide the highest-level evidence for interventions. Option A may lack empirical support. Option C has lower validity due to observational design. Option D is weaker if based on non-research sources. The clinical scenario involves direct intervention (dosing) and specific comorbidities (obesity/renal impairment), requiring robust evidence. Meta-analyses synthesize multiple RCTs to address heterogeneity in complex patients.
7. During admission medication reconciliation for a 72-year-old with renal impairment (eGFR 28 mL/min) and diabetes, the nurse notes home metformin use and a new prescription for IV contrast for a scheduled CT. The patient reports taking over-the-counter NSAIDs for arthritis. Which reconciliation finding requires immediate intervention?
Answer: B
NSAIDs pose acute renal toxicity risks with contrast and metformin in renal impairment, requiring immediate discontinuation per KDIGO guidelines. Option A is managed by standard glucose monitoring. Option C is important but doesn't directly address the imminent nephrotoxicity risk from NSAID-context interaction. Option D requires adjustment but is less urgent than active harm from NSAIDs. Cues (eGFR 28, contrast exposure, OTC omissions) highlight medication interaction dangers during transitions.
8. A concept map for an elderly fall victim with a hip fracture includes "Osteoporosis" and "Mobility Deficit." Pre-op labs show Na⁺ 128 mEq/L. Which added concept BEST explains the sodium result?
Answer: A
Hyponatremia in hip fracture patients often stems from SIADH triggered by pain/stress. Option A aligns with acute trauma context. Option B would typically cause hypernatremia. Option C and D lack supporting cues (e.g., no diuretic mentioned, normal baseline renal function implied). Orthopedic nursing protocols highlight SIADH screening in elderly trauma patients, as untreated hyponatremia increases delirium and mortality risk.
9. A hemodialysis patient with type 2 diabetes has pre-dialysis potassium of 6.2 mEq/L and phosphorus of 6.0 mg/dL. Which combined dietary restriction is critical?
Answer: A
Dairy is high in phosphorus; leafy greens high in potassium (NKF guidelines). Option A targets both abnormalities. Option B addresses sodium/phosphate but misses potassium sources. Option C reduces potassium/sugar but ignores phosphorus. Option D addresses phosphate/protein but not high-phosphorus dairy. Potassium 6.2 and phosphorus 6.0 exceed dialysis safety thresholds, requiring dual restriction.
10. In post-op recovery, a patient who had MH intraoperatively now has a core temperature of 38.9°C, K⁺ 6.2 mEq/L, and dark urine. Dantrolene was administered in OR. Which assessment requires the most urgent intervention?
Answer: C
Myoglobinuria and oliguria indicate acute kidney injury from rhabdomyolysis, requiring aggressive hydration to prevent tubular necrosis per MHAUS protocols. Hyperkalemia (B) is dangerous but was likely treated intraoperatively with calcium/insulin. Rebound hyperthermia (A) may require redosing dantrolene but isn’t immediately nephrotoxic. Tachycardia (D) is common post-MH but less critical than renal compromise. Dark urine and hyperkalemia are discriminators for rhabdomyolysis.
11. A patient with heart failure and CKD Stage 4 is discharged on furosemide. Serum potassium is 3.8 mEq/L today. Which follow-up action prevents electrolyte-related readmission?
Answer: B
Borderline potassium (cue: 3.8 mEq/L) and renal impairment (cue: CKD Stage 4) require systematic monitoring to prevent arrhythmias. Option A risks hyperkalemia without oversight. Option C is insufficient for lab-guided titration. Option D alters unverified therapy. AMSN guidelines mandate structured lab monitoring for renally cleared diuretics per KDIGO standards.
12. An LPN reports a patient's pain score increased from 3 to 7 after morphine administration. The patient has renal impairment and is drowsy. Which RN feedback to the LPN prioritizes safety?
Answer: C
Renal impairment increases morphine accumulation, and drowsiness with unrelieved pain suggests potential toxicity requiring immediate respiratory evaluation. This addresses the highest safety risk. Option A delays assessment despite red flags. Option B ignores the acute safety concern. Option D defers necessary nursing action. CMSRN guidelines stress evaluating delegated task outcomes for unexpected responses, especially with comorbidities affecting drug metabolism (AMSN Core Curriculum, 2021).
13. A nurse receives a telephone order for "furosemide 40 mg IV push now" for a patient with acute pulmonary edema and a history of chronic kidney disease (eGFR 28 mL/min). The patient's last potassium level was 5.6 mEq/L. Which action should the nurse take?
Answer: B
Furosemide can worsen renal function and potassium imbalances. The patient's elevated potassium (5.6 mEq/L) and severe renal impairment (eGFR 28) create high risk for hyperkalemia complications. Option A ignores these risks. Option C delays necessary intervention for pulmonary edema. Option D is appropriate but less urgent than directly questioning the order, as electrocardiogram monitoring doesn't address the core safety issue. Nurses must challenge orders when patient data suggests potential harm per safety standards.
14. A patient receiving epidural bupivacaine develops urinary retention 6 hours post-catheter removal. Bladder scan shows 650mL. Which action minimizes infection risk per guidelines?
Answer: A
Straight catheterization (A) reduces infection risk versus indwelling catheters (B) for acute retention. Bethanechol (C) is slow-acting and unreliable. Credé maneuver (D) is contraindicated with high volumes. CMSRN protocols favor intermittent catheterization post-epidural due to transient opioid effects. Volume >500mL requires drainage, prioritizing aseptic single-use over pharmacologic or indwelling options.
15. During shift handoff, a nurse learns a diabetic patient with renal impairment received conflicting insulin protocols from the hospitalist and nephrologist. The patient's blood glucose is 280 mg/dL, and they report confusion about which instructions to follow. Which systemic barrier should be prioritized for intervention?
Answer: A
The conflicting protocols (discriminating cue) and renal comorbidity (discriminating cue) indicate a system-level documentation flaw. EHR integration prevents contradictory orders, whereas Option B addresses knowledge deficits but not immediate safety risks. Option C/D focus on team processes but won't resolve existing conflicting orders. The CMSRN test plan prioritizes system fixes over education when protocols directly conflict. Option A aligns with Joint Commission standards for medication reconciliation.
