Staff Nurse Interview Questions

Model Answer & Framework

I adhere strictly to the core rights: Right Patient, Right Drug, Right Dose, Right Route, Right Time, Right Reason, and Right Documentation, along with right to refuse and right response assessment. In practice, I perform three checks: when removing the medication from storage, when preparing or scanning the dose against the electronic medication administration record (eMAR), and at the patient's bedside immediately before administration while asking the patient to state their full name and date of birth.

Model Answer & Framework

I never look at vital signs in isolation; I evaluate the trend over time and correlate numbers with physical observations—such as breathing effort, skin color, capillary refill, and mental alertness. Using early warning scoring systems like NEWS2, an escalating aggregate score or a single extreme score (such as respiratory rate >25 or systolic BP <90) triggers immediate clinical action: increasing monitoring frequency, performing a targeted ABCDE assessment, and escalating to the charge nurse or attending physician.

Model Answer & Framework

I use validated pain assessment scales suited to the patient: numerical 0–10 scale for alert adults, Wong-Baker FACES for pediatric or language barriers, or behavioral scales (such as CPOT or PAINAD) for non-verbal or ventilated patients. I assess pain characteristics (onset, location, quality, radiating, severity, and relieving factors), administer prescribed analgesia according to the WHO pain ladder, implement non-pharmacological interventions (repositioning, cold/heat packs), and re-evaluate pain efficacy within 30 to 60 minutes.

Model Answer & Framework

Prevention relies on initial Braden Scale risk scoring, routine skin inspection during every shift, scheduled two-hour repositioning, using pressure-relieving foam or alternating air mattresses, protecting bony prominences with silicone foam dressings, and applying barrier creams for incontinence moisture. Pressure injuries are staged from Stage 1 (non-blanchable erythema) through Stage 4 (full-thickness skin and tissue loss with exposed bone/muscle), along with unstageable and deep tissue injuries. Any new breakdown is documented with precise measurements and reported immediately to the wound care team.

Model Answer & Framework

Standard precautions are applied to all patients regardless of diagnosis: hand hygiene following WHO 5 Moments, appropriate PPE based on anticipated fluid exposure, safe sharps disposal in puncture-resistant containers, and routine decontamination of patient equipment. Transmission-based precautions are added for confirmed or suspected pathogens: Contact precautions (MRSA, C. diff requiring soap and water handwashing), Droplet precautions (influenza, pertussis with surgical mask and eye shield), and Airborne precautions (tuberculosis, measles requiring negative-pressure isolation and fitted N95/FFP3 respirators).

Model Answer & Framework

Early sepsis signs include altered mental state, tachycardia (>90 bpm), tachypnea (>20 bpm), fever (>38.3°C) or hypothermia (<36°C), mottled extremities, and oliguria. When suspected, I initiate the 'Sepsis Six' pathway within one hour: 1) Administer high-flow oxygen to maintain saturations >94%, 2) Draw blood cultures before giving antibiotics, 3) Initiate broad-spectrum IV antibiotics per hospital formulary, 4) Start IV fluid resuscitation (30ml/kg crystalloid for hypotension or lactate >=4 mmol/L), 5) Measure serum lactate, and 6) Monitor hourly urine output with a catheter.

Model Answer & Framework

I inspect peripheral cannula sites every shift for redness, swelling, warmth, tenderness, and leakage using a standardized Visual Infusion Phlebitis (VIP) score. For phlebitis, I immediately discontinue the cannula, elevate the extremity, apply a warm compress, and restart access in the opposite arm. For extravasation involving vesicant medications (like potassium, vasopressors, or chemotherapy), I stop the infusion immediately, aspirate residual medication from the cannula before removal, notify the physician, apply thermal compresses per drug protocol, and administer specific antidotes if indicated.

Model Answer & Framework

For conscious patients with blood glucose <70 mg/dL (4.0 mmol/L), I follow the 'Rule of 15': administer 15 to 20 grams of fast-acting simple carbohydrates (such as 4 glucose tablets or 120ml fruit juice), recheck blood glucose in 15 minutes, and repeat if still low; once resolved, provide a complex carbohydrate snack to maintain euglycemia. If the patient is unconscious, confused, or has an impaired swallow, oral intake is strictly contraindicated: I place the patient in the recovery position, establish patent IV access, administer 100–150ml of 10% Dextrose (or 50ml of 50% Dextrose per protocol) over 5 minutes, or give 1mg Intramuscular Glucagon if IV access is unavailable, followed by urgent medical escalation.

Model Answer & Framework

High-alert medications carry heightened risk of catastrophic harm when administered incorrectly. Safety precautions include: 1) Never administering concentrated IV potassium as a direct bolus; it must be diluted and infused via a controlled volumetric infusion pump with cardiac monitoring, 2) Conducting mandatory independent double-checks by two qualified nurses who independently verify the order, vial, dose calculation, pump programming, and patient identity, 3) Using standardized concentration bags, distinct labelling, and barcode medication scanning, and 4) Checking baseline lab values (potassium levels, aPTT/INR, blood glucose) prior to dose delivery.

Model Answer & Framework

Legally compliant documentation follows the golden rule: 'If it wasn't documented, it wasn't done.' Notes must be objective, factual, concise, legible, accurate, and recorded contemporaneously as events occur. I avoid subjective judgments (writing 'patient was shouting and threw water jug' rather than 'patient was aggressive'), record exact times of assessments and doctor escalations, document responses to interventions, and sign every entry. In electronic health records (EHR), I never share login credentials or backdate entries.

Model Answer & Framework

An SBAR handover structures critical data clearly: Situation (patient name, bed, diagnosis, current clinical stability), Background (relevant medical history, admission date, surgical procedures, allergies), Assessment (current vital signs, NEWS score, neurological status, IV lines, surgical wounds, drains, and fluid balance), and Recommendation (pending lab results, scheduled scans, titration plans, and specific deterioration triggers to watch for). Conducting this at the bedside engages the patient directly and allows direct visualization of line dressings, infusion rates, and patient appearance.

Model Answer & Framework

Safe discharge begins on admission. On the day of discharge, I ensure the formal medical discharge summary and medication prescription are verified. I review discharge medications with the patient and family, verifying they understand indications, dosages, and potential side effects. I confirm follow-up appointments, wound dressing supplies, removal of invasive lines/cannulas, return of personal belongings, and verify transport arrangements. Crucially, I provide clear red-flag discharge instructions outlining specific symptoms that necessitate immediate return to the emergency department.

Model Answer & Framework

When a near-miss or incident occurs, my first immediate priority is always patient safety: assess the patient, initiate corrective interventions, and notify the medical officer and charge nurse. Once the patient is stabilized, I document objective clinical findings and treatments in the patient chart without editorial commentary. Next, I submit a formal hospital incident report (e.g., Datix / incident management system). A 'just culture' is vital because it treats errors as systemic learning opportunities rather than individual fault, encouraging transparent reporting without fear of punitive retribution and allowing root causes to be fixed.

Model Answer & Framework

I approach distressed individuals with open, non-defensive body language, maintaining safe eye contact in a calm, moderate tone of voice. I listen actively without interrupting, acknowledging their emotional state ('I can see how frightening and frustrating this delay has been for you'). I validate their feelings, explain what is happening factually without medical jargon, outline concrete actions I am taking immediately, and set realistic expectations. If safety is threatened, I position myself near the exit, summon colleagues, and follow hospital security de-escalation protocols.

Model Answer & Framework

I focus strictly on the patient's objective clinical data rather than personal opinions. Using SBAR, I articulate the specific assessment finding causing concern (e.g., 'Dr. Smith, Mr. Brown's urine output has dropped below 15ml/hr for 3 consecutive hours despite fluid bolus, and his lactate is rising'). If the doctor dismisses the concern and I believe patient safety is jeopardized, I follow the clinical escalation chain: I respectfully restate my concern using graded assertiveness (CUS framework: I am Concerned, I am Uncomfortable, this is a Safety issue), request an in-person bedside review, and if unresolved, involve the charge nurse or attending consultant.

On a surgical ward when unexpected sick calls left our unit short-staffed, I gathered our team for a 5-minute huddle to triage workload. We prioritized non-negotiable safety tasks: high-alert medication administration, urgent post-op assessments, wound drain checks, and emergency call bells. We deferred routine non-clinical tasks, staggered staff break rotations to ensure continuous bedside coverage, and updated our nursing supervisor for agency floating support. By communicating openly with patients about potential delays for non-urgent requests and supporting colleagues, we completed the shift with zero safety incidents.

Model Answer & Framework

1) Call for immediate help using the emergency call bell and activate the Medical Emergency Team (MET) / Rapid Response Team. 2) Position the patient upright in high Fowler's position to optimize lung expansion. 3) Apply supplemental high-flow oxygen via non-rebreather mask to titrate saturation to >=94%. 4) Conduct a rapid ABCDE assessment: check airway patency, auscultate bilateral breath sounds (checking for absent breath sounds indicating pneumothorax, or crackles), assess pulses, and attach continuous ECG and blood pressure monitoring. 5) Ensure patent IV access, prepare emergency medications, order a 12-lead ECG, portable chest X-ray, and arterial blood gas (ABG) sampling, and deliver an immediate structured SBAR handover to the responding physician.

Model Answer & Framework

A competent adult patient has the legal and ethical right to refuse any medical treatment. My first step is not to force or argue, but to explore their reasoning with empathy ('Could you help me understand what's making you hesitate about this pill today?'). Frequently, refusal stems from manageable side effects (dizziness, nausea) or misconceptions. I explain the clinical rationale, what the medication does, and the potential risks of skipping the dose in understandable terms. If the patient maintains refusal, I respect their autonomy, withhold the drug, document the refusal and reasoning on the eMAR, inform the attending physician, and continue to monitor vital signs closely.

Model Answer & Framework

I immediately pause and withhold the medication; under no circumstances do I administer a dose with conflicting documentation. I do not guess which order is correct. I verify original diagnostic orders, check standard reference dosing in the hospital formulary or British National Formulary (BNF), and contact the prescribing doctor directly to clarify the discrepancy. Once confirmed, I ensure the electronic record or prescription is officially amended and signed before administration. If the discrepancy was an order error that was caught, I submit a near-miss safety report to prevent similar system slips.

Model Answer & Framework

I triage by immediate physical safety risk: 1) First Priority: The elderly confused patient climbing over bed rails represents an immediate, high-probability fall and traumatic injury risk. I attend to that patient immediately (or delegate a nearby nurse/HCA within eyesight) to stabilize them safely back in bed. 2) Second Priority: The alarming IV pump. I check the pump immediately after ensuring fall safety, as line occlusions can cause vein thrombosis, tissue extravasation, or interrupt critical infusions like vasopressors or insulin. 3) Third Priority: The post-op pain relief. Pain management is crucial, but airway/safety takes precedence; I acknowledge the patient, inform them that I will prepare their analgesia within 5 minutes, and deliver the medication promptly.
