SHORT ANSWER
Airway, breathing and circulation first, then safety, then acute over chronic. The RN keeps assessment, teaching, evaluation and unstable clients.
Which priority rule do you use first?
Apply these in order. Stop at the first one that separates the options.
- Airway, breathing, circulation. Anything threatening these right now wins.
- Safety. Falls, bleeding risk, suicide risk, infection spread, wrong patient or wrong drug.
- Acute over chronic. A new change beats a long-standing problem.
- Unstable over stable. Unexpected findings beat expected ones.
- Actual over potential. A problem happening now beats a risk.
- Maslow. Physical needs before psychosocial ones, unless the psychosocial need is a safety risk.
Worked example: four clients, one nurse
You receive report on four clients. Who do you see first?
- A client with COPD whose oxygen saturation is 90%, the same as her baseline.
- A client two days after surgery asking for pain medicine, rating pain 6 out of 10.
- A client four hours after a thyroidectomy whose voice is newly hoarse and whose breathing is noisy.
- A client with diabetes whose glucose is 180 mg/dL before lunch.
The thyroidectomy client. New hoarseness and noisy breathing after neck surgery suggest airway swelling or a hematoma, an immediate airway threat. The COPD client is at her baseline, so stable. The pain is real but expected and not life-threatening. The glucose is high but not an emergency.
Delegation: what can the RN hand off?
NCSBN and the American Nurses Association describe five rights of delegation: the right task, under the right circumstances, to the right person, with the right directions and communication, and with the right supervision and evaluation. Scope of practice varies by state and facility, so NCLEX questions follow general standards.
| Role | Can usually take | Stays with the RN |
|---|---|---|
| RN | Everything below, plus judgment calls | Assessment, care planning, initial teaching, evaluation, unstable clients |
| LPN/LVN | Stable, predictable clients; many oral and routine medications; reinforcing teaching; data collection | Initial assessment, new teaching, unstable clients, many IV tasks |
| Assistive personnel | Hygiene, feeding stable clients, ambulation, positioning, vital signs on stable clients, intake and output | Anything that needs assessment, teaching or interpretation |
Which delegation traps show up most?
- Any option with assess, teach or evaluate stays with the RN.
- A new admission or a client whose condition just changed goes to the RN.
- Assistive personnel can collect and report data, like vital signs, but not interpret it.
- An LPN can reinforce teaching the RN already started, but not begin it.
- Be careful with the first time a client does something after a change, like getting up after surgery. The RN usually does it.
How do you practice priority when things keep changing?
On the exam, priority questions inside a case study change as the data changes. The client who was stable at 08:00 may be the priority at 10:00. Practice with cases that move. RN Prep Pro shifts put several demands on you at once, such as a call light, a page and a worried family member, and the priority shifts as the story goes on. Maria explains the reason in one line whenever you pick the wrong client first.

Quick answers
What comes first on the NCLEX, airway or safety?
Airway, breathing and circulation come first when there is an immediate threat. Safety comes next. If no ABC problem is present, safety issues such as fall or bleeding risk usually take priority.
What are the five rights of delegation?
Right task, right circumstance, right person, right directions and communication, and right supervision and evaluation, as described in the NCSBN and ANA National Guidelines for Nursing Delegation.
Can an LPN give IV medications on the NCLEX?
LPN scope for IV therapy varies by state. NCLEX questions usually keep IV push medications, blood products and unstable clients with the RN, and assign stable, predictable care to the LPN.
