NMC CBT common mistakes
NMC CBT · Understand the traps and how to avoid them.
Choosing the option that shows what the nurse would personally do to help, rather than the option that shows escalating to the right person at the right time.
Candidates default to hands-on helpfulness and see escalation as passing the problem on or appearing incompetent, so they pick the 'reassure and stay with the patient' distractor over 'inform the nurse in charge and document'.
What to do instead
Before answering, ask 'whose role is this and what does the policy say happens next?' Practise ranking answers by safety and accountability: assess, act within your competence, escalate, then document. Treat escalation as an action, not a failure.
Ignoring the four-hourly and cumulative fluid balance figures in a scenario and answering from the single most recent observation instead.
Scenarios present a cluster of observations and candidates latch onto one abnormal value (often the latest) rather than reading the trend, so they miss deterioration that is only visible in the trajectory.
What to do instead
Scan every observation in order and write the trend in one line (e.g. 'urine falling, HR rising, BP falling over 6 hours'). Base the answer on the trend and on the recognised deterioration trigger, not the last number.
Selecting 'do nothing and keep monitoring' when a patient's condition meets a track-and-trigger escalation threshold.
Candidates fear over-reacting or being told off for calling for help, and the 'continue to monitor and reassess in an hour' option sounds calm and reasonable.
What to do instead
Memorise the principle that meeting an escalation trigger obliges action regardless of how well the patient 'looks'. When an option delays escalation past a trigger, eliminate it.
Answering communication questions with what the nurse says, while ignoring how it is said and what the patient is feeling.
Candidates treat communication as information-giving and pick the option that explains the most facts, missing that the question is testing empathy, checking understanding, or consent.
What to do instead
For every communication item, identify the patient's emotion or need first, then choose the response that acknowledges it and invites the patient to speak (open question, reflection, checking understanding) before any explanation.
Using closed questions or reassurance ('don't worry, you'll be fine') as the response to an anxious or distressed patient.
These feel kind and are quick, and candidates confuse comforting with therapeutic communication; false reassurance also feels safer than exploring distress.
What to do instead
Reject options containing 'don't worry', 'it'll be fine', or a leading closed question when distress is present. Prefer options that name the feeling, sit at the patient's level, and use open exploration.
Treating consent as a signature on a form rather than an ongoing process, and accepting consent from someone who lacks capacity.
Candidates conflate the paperwork with the legal and ethical standard, and assume a relative can consent on the patient's behalf.
What to do instead
Apply the test: does the patient have capacity, is the consent informed and voluntary, and is it continuing? Remember that no one can consent for an adult who lacks capacity; decisions are made in their best interests under the relevant legal framework.
Breaking confidentiality or sharing information without checking the lawful basis, or conversely refusing to share information when safeguarding requires it.
Candidates swing between over-disclosure (discussing a patient in a lift or with a curious relative) and over-protection (withholding information from a safeguarding lead), because they have not learned the exceptions.
What to do instead
Learn the disclosure test: is there consent, a legal obligation, a public-interest or safeguarding justification, and is the disclosure limited to those who need to know? Apply it to each option before choosing.
Failing to recognise and act on a safeguarding concern, or recording an opinion instead of facts.
Candidates worry about being wrong or damaging relationships, so they choose 'discuss with colleague and monitor' instead of reporting, and they write judgemental notes like 'patient was rude and seems neglected'.
What to do instead
Treat safeguarding as a duty to report concerns through the correct channel, not to investigate. For documentation items, choose the option that records observable facts, time, what was said and what action was taken.
Answering as a student or as a newly registered nurse when the question is written for a registered practitioner, or vice versa.
Candidates apply their own current scope and confidence level rather than the role stated in the question, so they pick 'ask someone else' when the registered nurse should act, or act beyond scope.
What to do instead
Read the stem for the role and setting first and answer within that scope. If the question describes a registered practitioner, choose the accountable action; if it describes a student, choose the action that involves supervision and escalation.
Rushing through long stems and multi-part scenarios, and changing correct first answers on a second pass without new evidence.
Time pressure and anxiety lead to skimming for keywords, and second-guessing replaces reasoned judgement with doubt, so candidates lose marks on items they initially got right.
What to do instead
Read the final question sentence before the scenario, underline the key finding, and answer in one pass. On review, only change an answer if you can name the specific fact you missed; otherwise keep it.
