New Jersey CNA common mistakes

New Jersey CNA · Understand the traps and how to avoid them.

Mistake 1

Performs hand hygiene when the skill begins but skips it after removing gloves, between a dirty and a clean step, or before touching clean equipment - and often turns the faucet off with bare hands after washing.

Candidates memorize hand hygiene as the 'first step' of each checklist skill rather than as a trigger-based habit, so it drops out whenever the step isn't printed at that point in the task.

What to do instead

Practice every skill with three spoken checkpoints: before touching the resident, after any contact with body fluids or soiled linen, and after glove removal. Rehearse the full sequence (wet, soap, 20 seconds, rinse, paper towel to dry and to turn off faucet) until it is automatic.

Mistake 2

Finishes a skill and walks away leaving the bed at working height with wheels unlocked, side rail down on a resident who needs it, or the call light on the floor or behind the pillow.

Attention is consumed by the clinical steps being graded, so the 'exit' steps feel like cleanup rather than part of the skill.

What to do instead

Adopt a fixed closing routine said out loud at the end of every practice run: bed low, wheels locked, rails as ordered, call light in hand, personal items within reach, resident positioned comfortably.

Mistake 3

Pivots or ambulates a resident without applying a gait belt, stands on the resident's strong side without checking for dizziness first, and lifts with the back instead of the legs.

Candidates focus on getting the resident from point A to point B and treat the belt, the dizziness check, and body mechanics as optional extras rather than graded safety steps.

What to do instead

Rehearse transfers as a scripted sequence: lock the chair, raise footrests, apply and check the belt, ask about dizziness, stand on the weaker side, count to three, pivot toward the strong side, lower with legs bent. Repeat with a partner until the order is fluent.

Mistake 4

During perineal or catheter care, wipes back to front, reuses a washcloth or the same glove for dirty-to-clean steps, and cleans along the catheter tubing toward the meatus instead of away from it.

The direction rule is remembered as a phrase but not connected to the reason (moving bacteria toward the urethra), so it collapses under time pressure.

What to do instead

Practice with the rule stated aloud before each stroke: front to back, one stroke per cloth, new cloth and new glove for each pass, catheter care from the meatus outward. Trace the path on a mannequin until direction is automatic.

Mistake 5

Begins a procedure without knocking, introducing themselves, stating what they are about to do, or draping the resident so only the body part being cared for is exposed.

Candidates rehearse the mechanical steps of the skill far more than the opening, so the introduction and draping get compressed into a rushed mumble or dropped entirely.

What to do instead

Build a four-part opening spoken at the door of every practice skill: knock, name and role, explain the task and ask permission, then drape. Have a partner flag any run where the opening is missing or the resident is left exposed.

Mistake 6

Keeps going when a resident says stop or pulls away, or answers a question about a preference (bath vs. shower, which shirt, when to use the toilet) by deciding for the resident.

Candidates fear that stopping will be scored as an incomplete skill, so they override refusal; offering choices is not seen as part of the task at all.

What to do instead

Practice the pause: stop immediately, cover the resident, ask what is wrong, and report the refusal to the nurse. Rehearse two-choice phrasing ('Would you like the bath now or after breakfast?') in every practice skill until offering a choice feels like a required step.

Mistake 7

Calls residents by pet names without permission, uses clinical jargon, finishes the resident's sentences, or discusses a resident's condition in the hallway, elevator, or at the desk.

Nervousness and time pressure push candidates into casual shortcuts, and the confidentiality rule is learned as a written concept rather than a habit about where conversations happen.

What to do instead

Use the resident's preferred name, plain words, and one question at a time; use a partner to practice redirecting family questions to the nurse. Treat any public area as a no-discussion zone and rehearse that boundary out loud.

Mistake 8

Charts care before it is delivered, writes 'resident was fine' or 'seems unhappy' on the flow sheet, or records a value that was never actually measured.

Charting is treated as the last item on a checklist to clear rather than a record of what happened, and candidates imitate vague phrasing they have seen on real forms.

What to do instead

Follow a firm sequence in practice: do the care, then chart immediately, using objective facts (what was done, what was observed, the actual numbers) and no judgments. Chart a refusal or a change as an incident and a report, not as a normal entry.

Mistake 9

Steps outside the role by accepting a verbal order, adjusting oxygen flow, applying a sterile dressing, giving a medication, or taking a blood pressure and acting on it without telling the nurse.

Candidates want to be helpful and are unclear where the aide's task list ends, so a request from a resident or family member is treated as authorization.

What to do instead

Memorize a short out-of-scope list to recite (medications, sterile dressings, oxygen settings, verbal orders, teaching, assessments) and practice declining politely: 'That's not something I can do - I'll get the nurse right away.'

Mistake 10

Notices a change in condition - new confusion, a reddened area, poor intake, a fall risk - writes it on the flow sheet, and never tells the nurse, or waits until the end of the shift.

Candidates believe that writing it down is the same as reporting it, and they worry about 'bothering' the nurse with something that may be nothing.

What to do instead

Practice a report script for every observed change: state the resident, room, what was seen, when it started, and the vital signs, and say it to the nurse in person right away. Treat reporting as complete only when a person has been told, not when a form has been filled in.
