MNMC Nursing common mistakes
MNMC Nursing · Understand the traps and how to avoid them.
Choosing the answer that describes what the nurse should do for the patient clinically, when the question actually asks about the nurse's legal or ethical obligation (for example, selecting "restrain the patient" instead of "document the refusal and notify the provider").
Candidates read the scenario's clinical urgency and default to intervention-mode thinking; they skim the stem's final clause, which often shifts the question from care to obligation (advocacy, informed consent, mandatory reporting, scope of practice).
What to do instead
Before answering, underline the operative words in the stem ("legal obligation", "ethical principle", "initial action", "priority"). If the stem asks about obligation, eliminate every option that is purely a clinical task. Practice by rewriting each practice question's stem into one sentence naming what is being asked, then answer only that.
Treating a patient's signed consent form as proof that consent was valid, and missing scenarios where the patient was medicated, confused, coerced, or uninformed about alternatives and risks.
Candidates equate documentation with validity; the form is evidence, not the thing itself. Exams test the elements of informed consent (capacity, voluntariness, disclosure of risks/benefits/alternatives, comprehension) rather than the paperwork.
What to do instead
For any consent item, run a four-point check in order: does the patient have decision-making capacity right now; was disclosure complete; was the choice voluntary; can the patient restate the decision in their own words. If any element fails, the correct answer usually involves stopping, clarifying, or escalating to the provider rather than proceeding.
Answering a priority question by picking the most dramatic or life-threatening-sounding option rather than applying a structured triage framework such as airway-breathing-circulation, then acute-before-chronic, then unstable-before-stable.
Under time pressure, candidates anchor on the most alarming word in the options (hemorrhage, arrest) even when the stem describes a stable patient with a subtle deterioration. The exam deliberately pairs a stable-but-urgent patient with a dramatic-but-lower-priority distractor.
What to do instead
Use a fixed algorithm on every priority item: ABC first, then assess for signs of instability (vital sign trends, mental status change, urine output), then Maslow or safety-risk ordering. Explicitly rank all four options before selecting, and write one line justifying why the runner-up is lower priority.
Selecting "document the incident" or "complete an incident report" as the first or only action after a fall, medication error, or needlestick, instead of first assessing the patient and providing immediate care.
Candidates memorize that incident reports are important and conflate importance with priority. They also confuse the incident report with the medical record and choose options that mention documenting in the chart, which is a common trap.
What to do instead
Sequence safety events as: patient assessment and stabilization, then notification per policy (provider, charge nurse, risk management), then documentation in the medical record, then the incident report as a separate non-chart document. Reject any option that places paperwork before assessment or that puts the incident report in the patient chart.
Jumping to a diagnosis or intervention from a single abnormal finding without first clustering the data (vital signs, labs, assessment findings, history) and checking whether the pattern is expected for this patient.
Candidates are trained to react to red-flag values and often skip the step of asking whether the finding is new, trending, or consistent with the patient's baseline. Exam items frequently provide one alarming value embedded in a reassuring context.
What to do instead
On every clinical-decision item, list the objective findings in a column and mark each as new, worsening, improving, or baseline. Only act on findings that are new or worsening, or that cross an established threshold. If two findings conflict, the correct answer usually calls for further assessment rather than immediate intervention.
Missing the transition-of-care failure hidden in a scenario, such as a patient discharged on a new anticoagulant with no follow-up scheduled, no written instructions, and no teach-back, and choosing an answer that only addresses the medication rather than the handoff.
Candidates focus on the visible clinical task (the drug, the dressing, the diet) and overlook the coordination elements the item is testing: who is responsible, what was communicated, and whether the receiving setting confirmed understanding.
What to do instead
For any discharge or transfer scenario, check five boxes: medication reconciliation completed, written instructions provided in plain language, teach-back documented, follow-up appointment arranged, and a named contact for questions. The best answer usually repairs the missing box rather than repeating a box already satisfied.
Choosing a high-alert medication answer based on the drug's usual dose or class rather than verifying the rights of administration and the specific safety checks (independent double-check, pump programming, rate, concentration) required for that drug.
Candidates rely on memorized dose ranges and forget that exam items test process safety: look-alike/sound-alike names, weight-based dosing, titration parameters, and the requirement for a second nurse verification.
What to do instead
For every medication item, state the drug's high-alert status, the calculation or rate, and the verification step before evaluating the options. If an option skips the independent double-check or the rate/concentration confirmation for a high-alert drug, eliminate it regardless of how correct the dose looks.
Accepting a verbal or telephone order, especially for a high-alert drug, without reading it back and without confirming which elements must be documented, and selecting the option that simply says "transcribe the order."
Candidates treat read-back as a courtesy rather than a required safety practice, and they do not distinguish orders that may be taken verbally from those that must be written.
What to do instead
Memorize the rule: read back the complete order (drug, dose, route, frequency, patient identifiers), have the prescriber confirm, document the read-back and the prescriber's name, and follow facility policy on which orders may be verbal. Any option that omits read-back or documentation of it is wrong.
Delegating an assessment, teaching, evaluation, or judgment-based task to unlicensed assistive personnel, or accepting a delegate's report of a change in condition without going to assess the patient.
Candidates conflate tasks that are routine with tasks that are delegable. They also assume that a reported change has already been validated, when the nurse remains accountable for assessment and clinical judgment.
What to do instead
Apply the delegation decision tree: is the task within the delegate's scope, is it predictable, does it require nursing judgment, and is supervision available? Assessment, teaching, evaluation, and any unstable patient are never delegable. When a delegate reports a change, the correct next action is for the nurse to assess the patient.
Giving patient education as a single list of instructions at discharge, without assessing health literacy, readiness to learn, or barriers, and without using teach-back to confirm understanding.
Candidates equate telling with teaching and choose the option that contains the most information rather than the option that verifies comprehension. Exam items reward the teach-back and the assessment of readiness and barriers.
What to do instead
Structure every education item as assess (literacy, readiness, barriers, prior knowledge), teach in small chunks using plain language, then confirm with teach-back or return demonstration. Reject options that only provide written material, use jargon, or skip the confirmation step.
