Clinical Nurse Specialist Risk Assessment & Management 5 — Questions and Answers
Question 1: A CNS is designing a protocol to reduce central line-associated bloodstream infections (CLABSI). Which bundle element has the highest evidence for prevention?
- Changing central line dressings every 24 hours regardless of condition
- Using maximum sterile barrier precautions during central line insertion (Correct answer)
- Flushing lines with heparin solution after every use
- Replacing central lines every 72 hours on a routine schedule
Correct answer: Using maximum sterile barrier precautions during central line insertion
Maximum sterile barrier precautions during insertion—including cap, mask, sterile gown, sterile gloves, and full drape—are a cornerstone of the evidence-based CLABSI prevention bundle.
Question 2: A CNS is assessing a patient for risk of delirium in the ICU. Which factor is MOST strongly associated with ICU-acquired delirium?
- Female sex and age under 60
- Benzodiazepine use and mechanical ventilation (Correct answer)
- History of mild anxiety disorder
- Single-room occupancy in the ICU
Correct answer: Benzodiazepine use and mechanical ventilation
Benzodiazepine sedation and mechanical ventilation are among the strongest independent risk factors for ICU-acquired delirium based on robust evidence.
Question 3: Under a systems thinking approach to patient safety, a CNS attributes a medication administration error primarily to:
- Individual nurse negligence and lack of attention
- Flaws in processes, systems, and working conditions that allowed the error (Correct answer)
- Insufficient nursing education in pharmacology
- Failure of the patient to ask about medications before administration
Correct answer: Flaws in processes, systems, and working conditions that allowed the error
Systems thinking recognizes that errors are usually the result of faulty processes and system conditions rather than individual failings, enabling more effective prevention strategies.
Question 4: A CNS is evaluating a diabetic patient's risk for foot amputation. Which finding carries the HIGHEST predictive risk?
- Mild callus formation on the plantar surface without ulceration
- Loss of protective sensation confirmed by 10-gram monofilament test failure (Correct answer)
- HbA1c of 7.5% with stable glycemic trends
- Occasional mild peripheral edema without skin breakdown
Correct answer: Loss of protective sensation confirmed by 10-gram monofilament test failure
Failure to detect the 10-gram monofilament confirms loss of protective sensation, the primary risk factor for undetected trauma leading to ulceration and amputation.
Question 5: Which approach best describes how a CNS applies the hierarchy of controls to reduce a workplace violence risk on an inpatient psychiatric unit?
- Training nurses to use verbal de-escalation techniques (administrative control)
- Requiring staff to sign an acknowledgment that they understand violence risk (administrative control)
- Installing locked door access and reducing environmental stimuli (engineering control) (Correct answer)
- Providing personal protective equipment to all staff entering patient rooms
Correct answer: Installing locked door access and reducing environmental stimuli (engineering control)
Engineering controls such as locked-door access and environmental modification rank higher in the hierarchy than administrative training because they reduce hazard at the source.
Question 6: A CNS is calculating risk priority number (RPN) in an FMEA exercise. RPN is calculated by multiplying which three factors?
- Frequency, duration, and reversibility
- Severity, occurrence, and detectability (Correct answer)
- Probability, impact, and cost
- Incidence, prevalence, and mortality
Correct answer: Severity, occurrence, and detectability
In FMEA, RPN = Severity × Occurrence × Detectability, and a high RPN identifies failure modes that require the most urgent corrective action.
Question 7: A CNS is assessing a patient with a known penicillin allergy who requires antibiotic therapy. Which risk-management principle guides the decision to use a cephalosporin?
- Cephalosporins are completely safe for all penicillin-allergic patients due to no cross-reactivity
- Cross-reactivity risk is low but present; individualized risk-benefit assessment and allergy clarification are required (Correct answer)
- All beta-lactam antibiotics must be permanently avoided in penicillin-allergic patients
- Skin testing is never necessary before cephalosporin use in penicillin-allergic patients
Correct answer: Cross-reactivity risk is low but present; individualized risk-benefit assessment and allergy clarification are required
Cross-reactivity between penicillins and cephalosporins is low (approximately 1–2%) but real, requiring individual risk-benefit analysis, allergy history clarification, and sometimes skin testing.
