SNB Client Assessment, Perioperative, Wound Care and Mobility Questions

Scope and time budget

Seven questions is about seven minutes. Stems often give a set of observations or a short clinical story and ask for the priority, the finding that needs action or the correct intervention. The SNB test plan lists client assessment and re-assessment, pre- and post-operative care, wound care and mobility and ambulation as separate categories, and they share one thread: look, measure, compare with baseline and escalate early. This domain rewards nurses who read numbers, not only words.

What is tested

• Vital signs and early warning scores. Normal ranges for adults, trends versus single readings, and what to do when a score rises. Know your institution's escalation rule and be ready to apply it.
• Systematic and focused assessment. Head-to-toe assessment, system-focused assessment after a change, and re-assessment after an intervention.
• Pain assessment. Use a valid tool, include location, intensity, quality and effect, reassess after analgesia and recognise pain in patients who cannot self-report.
• Neurological observation. Glasgow Coma Scale, pupils, limb power, and signs of raised intracranial pressure or deterioration.
• Pre-operative preparation. Consent, identification, fasting, skin preparation, medicine instructions, baseline observations and patient education.
• Post-operative monitoring. Airway, breathing, circulation, pain, wound, drains, urine output, nausea, temperature and signs of haemorrhage, infection, ileus and respiratory complications.
• Recovery after anaesthesia. Airway management, positioning, oxygen, and handover.
• Drains, tubes and stomas. Patency, output, appearance and skin care.
• Wound healing and dressings. Types of wound and healing, choosing a dressing to match the wound bed, and signs of infection or dehiscence, including negative pressure therapy.
• Pressure injuries. Staging, prevention and management.
• Mobility and assistive devices. Safe ambulation, walking aids, transfers and use of equipment.
• Immobility complications. Venous thromboembolism prevention, respiratory complications, contractures and skin breakdown.
• Fractures, traction and casts. Neurovascular checks, cast care and signs of compartment syndrome.

Singapore points to anchor your answers

• Early warning. Singapore hospitals use early warning scoring and rapid response processes. Questions expect you to recognise deterioration and escalate using SBAR, not to wait.
• Standard thresholds. Clinical ranges follow international guidance, with SI units and Singapore drug names. Confirm any threshold you use with a current source.
• Setting. Questions may be set in acute wards, day surgery, community and nursing homes. In the community and nursing home, a pressure injury or wound is also a quality indicator.
• Documentation. Accurate observations and wound records are part of legal practice and quality improvement.

Three typical traps

1. Reassuring when the trend is worsening. A blood pressure that is still within range but falling, with a rising pulse, is more worrying than a single abnormal figure that is stable. Read trends.
2. Treating the wound, not the cause. A pressure injury needs offloading and nutrition as well as dressing. A surgical wound with signs of infection needs escalation, not a stronger dressing alone.
3. Missing the neurovascular check. In fractures, casts and traction, the earliest warning is pain out of proportion, altered sensation or colour change. Check, compare sides and call early.

How to revise it

1. Write a normal values card for adult vital signs, and add the actions for abnormal values.
2. Draw a post-operative timeline from the recovery room to day three, with the usual complications and their signs at each stage.
3. Make a dressing table with wound type, aim and common dressing options.
4. Practise the Glasgow Coma Scale until you can score a short description in seconds.
5. Do 20-question timed blocks that mix assessment and surgical stems.
6. Practise SBAR for deterioration, with the numbers you would give.

Pair this domain with emergencies and critical care, nutrition, fluids and elimination and quality and safety.

Worked reasoning patterns

Trend over snapshot

When a stem lists observations from several times, plot them in your head. A pulse that climbs while blood pressure falls and urine output drops suggests bleeding or sepsis even if each number alone looks borderline. Pick the option that acts on the trend.

Compare with baseline

For neurological and neurovascular questions, the key is change from baseline. A drop of two points on the Glasgow Coma Scale or a cool, pale limb with new pain is a call for help.

Match the dressing to the wound

Dry wounds need moisture, wet wounds need absorption, infected wounds need assessment and escalation, and necrotic tissue needs a plan from the team. Ask what the wound bed looks like before you choose.

Revision targets

For range values, always check a current clinical source before you commit a number to memory, because ranges and scoring schemes differ between institutions.

Common distractors to recognise

• "Document and recheck in an hour" when the trend is worsening.
• "Apply a stronger dressing" to a wound that shows signs of infection.
• "Encourage fluids and rest" for post-operative pain that is increasing beyond what analgesia should control.
• "Massage the calf" when deep vein thrombosis is suspected.

Each is tempting because it sounds caring, yet each delays recognition of a problem that needs escalation.
