PSB-RNSAE common mistakes
PSB-RNSAE · Understand the traps and how to avoid them.
When a question asks what the nurse should do first or which client to see first, the candidate picks the intervention that resolves the problem rather than the one that assesses or stabilizes the client. For example, on a client with new-onset confusion and a blood glucose of 48 mg/dL, the candidate selects 'give oral glucose' before 'stay with the client and recheck the glucose.'
Candidates memorize interventions as paired facts (hypoglycemia equals glucose) and skip the step of deciding whether the situation is stable or unstable. The exam consistently rewards assessment and safety first when the client is unstable, and candidates lose points because they answer the disease instead of the priority.
What to do instead
Before answering any priority question, ask two questions: is this client stable or unstable, and is there an immediate threat to airway, breathing, circulation, or safety? If unstable, the correct first action is almost always assessment, positioning, or calling for help, not the definitive treatment. Practice by writing the first three actions for each scenario you study and ranking them by immediacy.
The candidate assigns a task to unlicensed assistive personnel (UAP) that requires nursing judgment, such as teaching a client about a new medication, performing an initial assessment, or evaluating whether a dressing change is needed. They justify it because the task seems simple or the UAP is experienced.
Candidates confuse 'routine' with 'delegable.' They remember that vital signs and hygiene can be delegated but do not apply the rule that assessment, teaching, evaluation, and any task requiring clinical judgment stay with the RN. The exam tests the boundary, not the task list.
What to do instead
Use the delegation rule: the RN keeps anything involving assessment, teaching, evaluation, or unstable clients. UAP can perform standard, predictable tasks with a stable client and a known outcome. When a delegation option appears, check all three: is the client stable, is the task predictable, and does it require judgment? If any answer is no, it is not delegable.
The candidate treats standard precautions as optional when a diagnosis is not yet known, or skips hand hygiene and personal protective equipment because the client 'looks clean' or the task will be quick. They also reuse gloves between clients or between dirty and clean tasks on the same client.
Candidates study transmission-based precautions as separate facts and treat standard precautions as background knowledge. Under time pressure they choose the option that sounds most thorough (gown and gloves for everyone) or the fastest (gloves only), rather than the option that matches the actual route of transmission and the task.
What to do instead
Anchor every infection-control question on two steps: identify the route of transmission, then select the minimum barrier that blocks it. Standard precautions apply to every client, every time, and gloves never replace hand hygiene. Review the specific precautions for contact (MRSA, C. difficile, scabies), droplet (influenza, pertussis, meningitis), and airborne (tuberculosis, measles, varicella) until you can state the required barrier and room type without hesitation.
The candidate answers a health promotion question with the treatment of a disease rather than the screening, immunization, or lifestyle counseling that is appropriate for the client's age and risk. For example, they recommend a colonoscopy to a 30-year-old with no risk factors instead of discussing the recommended screening schedule.
Candidates overlearn disease management and underlearn the preventive schedule. They also fail to read the age, sex, and risk factors in the stem, so they apply an adult recommendation to a pediatric or older adult client.
What to do instead
Build a one-page screening and immunization grid by age group and risk category, and review it before the exam. On each question, circle the client's age and risk factors first, then match the recommendation to that specific client. If the option describes treating an existing condition and the stem asks about prevention, eliminate it.
The candidate responds to a client who is angry, grieving, or refusing care with reassurance, advice, or a factual explanation instead of acknowledging the client's feelings. They choose 'explain that the procedure is safe' when the client says they are terrified.
Candidates equate helping with solving. They select the option that provides information because it feels productive, but therapeutic communication questions reward recognition and exploration of the client's emotion before any teaching or problem-solving.
What to do instead
When a stem contains a strong emotion, eliminate any option that gives advice, minimizes the feeling, or changes the subject. Look for the option that names or invites the feeling, such as 'tell me more about what worries you.' Practice by labeling the emotion in each psychosocial stem before reading the options, then choosing the response that reflects it back.
The candidate positions, feeds, or ambulates a client without applying the matching safety measure, such as turning a client with a spinal cord injury without spinal precautions, feeding a client with dysphagia while they are flat, or leaving a client with a fall risk unattended in the bathroom.
Candidates focus on completing the comfort task and treat positioning and mobility as mechanical skills. They do not connect the underlying diagnosis to the specific risk it creates, so they miss the safety step embedded in the correct option.
What to do instead
For every basic care question, name the client's primary risk before reading the options: aspiration, pressure injury, falls, contracture, or skin breakdown. Then choose the option that addresses that risk directly. Memorize the high-risk pairings, such as dysphagia with upright positioning and thickened liquids, immobility with repositioning every two hours, and spinal injury with logrolling.
The candidate calculates a medication dose correctly but selects the wrong administration route, rate, or timing, or fails to check for a contraindication before giving the drug. They also answer a question about a high-alert medication without verifying the required double-check or monitoring parameter.
Candidates treat dosage calculation as the whole skill and stop there. They also rush the stem and miss the vital sign, lab value, or allergy listed in the client data that makes the ordered drug unsafe.
What to do instead
For every pharmacology question, run a fixed checklist before choosing: right client, right drug, right dose, right route, right time, and the specific monitoring parameter for that drug class. Identify the high-alert drugs (insulin, heparin, opioids, chemotherapy, concentrated electrolytes) and know the double-check and monitoring requirement for each. Practice calculations separately until they are automatic, so exam time goes to safety checks.
The candidate interprets a single abnormal value in isolation, such as a potassium of 5.6 mEq/L or a hemoglobin of 7 g/dL, and chooses an intervention without considering the trend, the client's baseline, or the complication the value predicts.
Candidates memorize normal ranges and stop at 'abnormal.' The exam tests whether the candidate can connect a value to the risk it creates, such as dysrhythmia with hyperkalemia or tissue hypoxia with anemia, and act on that risk.
What to do instead
For each lab or vital sign you review, write the complication it predicts and the first nursing action for that complication. When a stem gives a value, ask what could go wrong in the next hour and choose the option that prevents or detects that complication. Compare the value to the client's baseline and trend when the stem provides them.
The candidate manages a deteriorating client by continuing routine care, such as completing a full set of vital signs or finishing a scheduled treatment, rather than recognizing the early signs of shock, sepsis, or respiratory failure and escalating care.
Candidates learn each condition separately and do not recognize the shared early warning pattern of deterioration: rising heart rate, falling blood pressure, increasing respiratory rate, changing mental status, and decreasing urine output. They wait for a dramatic sign before acting.
What to do instead
Memorize the early warning pattern and apply it to every physiological adaptation stem. If a client shows two or more of these signs, the correct answer is escalation, not routine care. Practice by reading only the vital signs and mental status of a scenario and predicting whether the client is stable, deteriorating, or critical before reading the question.
The candidate reads the stem once, recognizes a familiar diagnosis, and selects an answer that fits that diagnosis without checking whether the question asks what to do first, what to teach, which client is at greatest risk, or what finding requires follow-up.
Pattern recognition is fast and feels efficient under exam time pressure, so candidates skip the step of identifying the actual task. Many wrong answers are true statements about the diagnosis but do not answer the question asked.
What to do instead
Before reading the options, underline the task word in the stem and restate the question in your own words. After choosing an answer, verify that it answers that specific task and that every part of the option is true, not just the part you recognized. If two options seem correct, return to the task word and the client's stability to break the tie.
