Basic Nursing Skills

  • Normal adult ranges: pulse 60-100 beats/min, respirations 12-20 breaths/min, oral temperature 36.5-37.5 °C (97.6-99.6 °F), SpO2 95-100%.

  • Count respirations for a full 60 seconds while the resident believes you are still holding the pulse; one rise and fall of the chest equals one breath.

  • Rectal temperatures read about 0.5-1 °F (0.3-0.6 °C) higher than oral readings; axillary readings run about 1 °F lower than oral.

  • Intake/output conversion: 1 ounce = 30 mL, 1 cup (8 oz) = 240 mL, 1 teaspoon = 5 mL; record all oral fluids and all urine, vomitus, and drainage in milliliters.

  • Measure an apical pulse with a stethoscope at the fifth intercostal space, left midclavicular line, counting a full minute; a full-minute count is also required when the radial rhythm is irregular.

  • Thresholds to report immediately: systolic change of 20 mmHg or more from baseline, pulse under 60 or over 100 at rest, respirations under 12 or over 20, temperature above 101 °F (38.3 °C), SpO2 below 92%.

  • Urine output of less than 30 mL per hour for two consecutive hours is reported to the licensed nurse.

  • Range-of-motion exercises are carried only to the point of resistance, never beyond it; stop the exercise if the resident reports pain.

  • The blanching test: a reddened area over a bony prominence that stays red after your finger is removed is reported as a possible pressure injury.

Personal Care and Activities of Daily Living

  • Turn and reposition an immobile resident at least every 2 hours, more often if skin is already at risk, and record each position on the turning schedule.

  • Bathe from cleanest to dirtiest: face, neck, arms, chest, abdomen, legs, back, and perineal area last, using a fresh area of the washcloth for each stroke.

  • Perineal care always moves front to back (urethra toward rectum) so bacteria from the bowel are not carried to the urinary opening.

  • Bath water should be no hotter than 105 °F (about 40.5 °C); test it on your inner wrist before it touches the resident.

  • Dress the weak or affected side first and undress that side last when a resident has had a stroke or has one-sided weakness.

  • Do not trim the toenails of a resident with diabetes or poor circulation; report the need to the licensed nurse.

  • NPO means nothing by mouth; the resident still receives mouth care and lip care, and the call light stays within reach.

  • Brush dentures over a sink lined with a towel or partly filled with water so they will not break if dropped, and store them in a labeled cup.

  • Semi-sitting (Fowler's) position raises the head of the bed 45-60 degrees and is used for eating and for residents with breathing difficulty.

Safety and Emergency Response

  • RACE order for fire: Rescue anyone in danger, pull the Alarm, Contain fire by closing doors, then Extinguish or Evacuate.

  • PASS for an extinguisher: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.

  • Water never goes on an electrical or grease fire; electrical fires require a Class C (or ABC) extinguisher.

  • Fall prevention bundle: bed in lowest position, wheels locked, call light within reach, non-skid footwear, adequate lighting, clear pathways.

  • A restraint requires a physician's order and the least restrictive device; it is released and the resident checked at least every 15 minutes, and it is never tied to side rails.

  • Seizure: protect the head, move objects away, loosen tight clothing, restrain nothing and place nothing in the mouth, then turn the resident to the side when the seizure ends.

  • Adult CPR by a single rescuer uses 30 compressions to 2 breaths, compressing at least 2 inches deep at 100-120 compressions per minute.

  • Oxygen safety: post no-smoking signs, keep oxygen away from open flame, avoid petroleum-based products, and store cylinders upright and secured.

  • An incident report is completed for any accident, error, or injury using objective facts only; the report is not filed in the medical record.

Communication and Interpersonal Skills

  • Knock before entering, identify yourself by name and role, and address the resident by the name the resident prefers.

  • Answer call lights promptly; if there will be a delay, tell the resident how long it will be rather than leaving the light unanswered.

  • With a hearing-impaired resident, face them at eye level, lower the pitch of your voice, cut background noise, and never shout into the ear.

  • For a resident with aphasia, ask yes/no questions, allow extra time to respond, and do not finish sentences for them.

  • Do not argue with a confused resident about facts; redirect to a safe topic or activity instead of correcting the resident's reality.

  • Report observations objectively: "Mr. J. ate 25% of lunch and said his stomach hurt," not "Mr. J. was difficult today."

  • For medical information with a resident who speaks another language, use a qualified interpreter or the facility language line, not a family member.

  • Protect privacy: close doors and curtains during care, and share health information only with members of the care team (HIPAA).

Role and Responsibilities of the Nurse Assistant

  • Perform only tasks that are within the nursing assistant's legal scope and have been delegated by the licensed nurse; medication administration, sterile procedures, and resident teaching fall outside that scope.

  • Report changes in condition to the licensed nurse in charge, not to another nursing assistant.

  • If it is not documented, it is treated as not done; record care immediately after giving it and never chart care in advance.

  • Never chart another person's work and never alter a record; correct an error with a single line, the date, time, and your initials.

  • Suspected abuse, neglect, or misappropriation of property is reported immediately to the nurse in charge and the administrator; the nursing assistant is a mandatory reporter.

  • Resident rights include refusing care, privacy, freedom from unnecessary restraints, and voicing grievances without retaliation.

  • When a resident refuses care, honor the refusal, do not threaten or force, document it, and notify the licensed nurse.

  • Accept only assignments you are competent to perform, and request training or supervision when a task is unfamiliar.
