Assignment vs Delegation, explained for the bedside and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
An assignment transfers work that already sits within a nurse's scope of practice; delegation transfers a task outside that scope to someone else, typically a UAP. The nurse who assigns keeps standard accountability for the outcome. The nurse who delegates keeps accountability for the decision to delegate and for supervision, but not for how the task itself is performed.
Defining it precisely
Assignment and delegation get used interchangeably on the unit, which is exactly why the distinction is worth holding onto. An assignment gives a task to someone whose license or job description already covers it. A charge nurse assigning a med-surg RN to take four patients on the shift is an assignment: the RN's scope already includes assessment, medication administration and evaluation, so nothing has moved outside the boundary of what that role can legally do.
Delegation is different. It hands a task to someone whose scope does not normally include it, most often a UAP or LPN/LVN, and the delegating RN remains responsible for choosing the right task, the right person and the right level of supervision. The task itself, once delegated, is performed under someone else's hands, but the judgment behind the choice to delegate stays with the RN. That judgment is what gets tested.
The exceptions that matter
Not every task can be delegated regardless of how busy the floor is. Assessment, evaluation, nursing judgment and anything requiring teaching cannot be handed to a UAP, because these require the licensure and critical thinking an RN scope protects. A UAP can take vital signs and report a number; only the licensed nurse can interpret that number against the patient's baseline and decide what it means.
State nurse practice acts vary on where LPN/LVN scope ends, particularly around IV push medications, blood administration and initial assessments, so a task delegable to an LPN in one state may not be in another. Facility policy adds a second layer on top of the state act and can be more restrictive, never less. When a question does not specify jurisdiction, answer from the most conservative, universally-accepted scope rather than guessing at a specific state's allowance.
Using it to prioritise
The five rights of delegation, right task, right circumstance, right person, right direction and right supervision, function as a filter for what to keep and what to hand off when time is short. A stable, predictable task with a clear expected outcome is a delegation candidate. An unstable patient or a task with an unpredictable outcome stays with the RN regardless of how much is on the list.
This becomes a prioritisation tool the moment a shift gets stacked. If four things need doing and one is delegable, delegating it does not just clear a task, it frees the RN's attention for the assessment-level work that cannot be moved. Choosing what to delegate first, rather than delegating the easiest thing, is what separates competent time management from just offloading busywork.
Traps in exam wording
NCLEX items often disguise an assignment as a delegation question by giving you two RNs and asking who should take a patient. If both staff members are RNs, this is an assignment question about matching patient acuity to competency, not a delegation question about scope. Answering it with delegation logic, checking whether the task is within scope, wastes time because scope is not the variable being tested.
The reverse trap places a UAP in the stem and asks what they can safely do. Here the test is scope, and the correct answer is usually the most concrete, most stable, least judgment-dependent option on the list, things like ambulation, bathing, or repositioning a stable patient. Read the credentials in the stem before the task; the credentials tell you which framework, assignment or delegation, actually applies.
Examples from practice
A charge nurse gives an RN a fresh post-op patient and a stable chronic-disease patient for the shift, that is an assignment, matching acuity and skill to load. The same charge nurse asks a UAP to record intake and output for both patients and report anything unusual, that is delegation: the task moves outside the UAP's normal independent judgment, so the RN retains responsibility for acting on what is reported.
A trickier example: an RN asks an LPN to hang a maintenance IV fluid. Whether that is within the LPN's scope depends on the state practice act and the facility policy on IV therapy certification for LPNs, some states permit it with additional certification, others reserve it for RNs. This is precisely the kind of task where the safe answer, absent a stated jurisdiction, is to confirm scope before assuming it is delegable.
Summary
Assignment moves work within an existing scope of practice and carries ordinary accountability for the outcome. Delegation moves a task outside that scope to someone else, and the delegating nurse remains accountable for the decision and the supervision, not the execution. Recognising which one a scenario describes, by checking the credentials involved before the task, resolves most of the confusion these questions are built to create.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our prioritization and delegation practice questions are the closest set to what this page covers.
Common questions
Can an RN delegate medication administration to a UAP?
No. Medication administration requires nursing judgment about the patient's response and falls outside a UAP's scope in every jurisdiction. It can be assigned to another RN, or in some states delegated to an LPN/LVN depending on the medication route and facility policy, but never to unlicensed staff.
Who is legally responsible if a delegated task goes wrong?
The person who performed the task is accountable for how they performed it. The RN who delegated remains accountable for choosing an appropriate task and person, and for providing adequate supervision, so both can carry responsibility depending on where the failure occurred.
Is delegating to an LPN the same as delegating to a UAP?
No. An LPN/LVN holds a license with a broader scope than a UAP, so more tasks are delegable to them, including some medication administration in many states. The five rights of delegation still apply, and the RN still verifies competency before handing off any task.
Why do NCLEX questions favour assignment over delegation in staffing scenarios?
Most staffing decisions on a real unit involve matching RNs to patients by acuity, which is assignment, not delegation. The exam tests delegation separately, usually with a UAP or LPN explicitly named in the stem, so questions default to assignment logic whenever every staff member listed is an RN.
