Nursing care
Assault, Battery and False Imprisonment, explained for the bedside and the exam
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Assault is threatening a patient with unwanted treatment or contact; battery is carrying out that contact without consent, such as giving an injection the patient refused. False imprisonment is restricting a patient's movement without legal justification, such as restraining or discharging-blocking a patient without a valid order. All three can occur even when the nurse intends no harm.
What the concept actually says
Assault is an act that creates a reasonable fear of imminent harmful or offensive contact. A nurse who tells a patient, 'if you don't take this pill I'll give you the injection instead,' after the patient has refused, has committed assault the moment that threat lands, even if the injection never happens.
Battery is the actual unauthorized contact. If that same nurse gives the injection anyway, over the patient's clear refusal, that is battery, regardless of whether the medication was clinically indicated or the intent was to help. Consent, not clinical correctness, is what determines whether contact is lawful.
False imprisonment is restricting a competent patient's freedom of movement without legal authority, such as applying restraints without a current order, or telling a patient they cannot leave when they have the legal right to. A patient who signs in voluntarily generally retains the right to leave against medical advice unless a specific legal hold applies.
The clinical reasoning behind it
These torts exist because a patient's right to bodily autonomy does not disappear because they are sick, confused, or non-compliant. A confused patient can still refuse care in the moment, and lack of full capacity does not automatically authorize a nurse to override that refusal without proper legal process, such as obtaining a healthcare proxy's consent or an emergency exception.
Restraint use has a specific clinical and legal pathway for a reason: unordered or prolonged restraint carries real risk of injury, and the law requires a current physician or independent practitioner order, ongoing assessment, and the least restrictive alternative first. Understanding this reasoning prevents nurses from defaulting to restraint or forced medication as the fastest way to manage a difficult situation.
Applying it under time pressure
When a patient refuses a medication or treatment, stop, explain the risks of refusal, document the refusal and the education given, and notify the provider. Do not repeat the threat of an alternate route or method as leverage; that framing alone can constitute assault even without follow-through.
When a patient is agitated and movement needs to be restricted for safety, use verbal de-escalation and the least restrictive intervention first, and obtain an order for restraint as soon as the situation allows, following facility protocol for emergency application and subsequent order confirmation within the required window. Reassess and document per policy, typically at short, defined intervals, and remove restraints as soon as the criteria for their use no longer apply.
Common misconceptions
A common misconception is that good intent is a defense. It is not. A nurse who administers a medication against a competent patient's explicit refusal because 'it was for their own good' has still committed battery; motive affects the moral read of the situation but not the legal one.
Another misconception is that assault requires actual contact. It does not; the threat alone, if it creates reasonable fear of imminent unwanted contact, is enough. A third misconception is that any use of restraint is automatically false imprisonment. Properly ordered, clinically justified, time-limited restraint with appropriate reassessment is lawful. It becomes false imprisonment when it is applied without an order, continued past the point of clinical necessity, or used for staff convenience rather than patient safety.
Practice scenarios
A patient refuses a scheduled antipsychotic injection. The nurse says, 'if you won't take the pill, I'll have to give you the shot instead,' and the patient, frightened, complies. The threat itself, once the patient had already refused, is assault, because it created fear of unwanted contact used to override a refusal.
A post-operative patient asks to get up and walk to the bathroom unassisted. The nurse, worried about a fall, tells the patient they are not allowed out of bed and are not permitted to leave, with no order restricting activity and no documented safety rationale beyond general caution. If the patient is competent and there is no valid clinical or legal basis restricting movement, this can constitute false imprisonment, particularly if reinforced by threats or physical blocking.
Key takeaways
Consent governs contact, not clinical benefit. A competent, informed refusal must be respected and documented, with escalation to the provider rather than coercion.
Restraint requires a current order, ongoing assessment, and the least restrictive approach; skipping any of these steps moves a safety intervention into false imprisonment. Threats of unwanted treatment carry legal weight independent of whether the treatment is ever given, so language matters as much as action.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our fundamentals practice questions are the closest set to what this page covers.
Common questions
Can a nurse give a medication to a confused patient who is refusing it?
Not by simply overriding the refusal. If the patient lacks capacity, the nurse needs consent from an appropriate surrogate decision-maker or must follow the facility's emergency treatment protocol; confusion alone does not authorize forced administration.
Is it battery if the patient consents verbally but not in writing?
Verbal consent is generally valid for most nursing care; written consent is typically required only for specific procedures under facility policy or state law, such as surgery or certain treatments. Acting within a clear verbal consent is not battery, but documentation of that consent still matters.
How long can a nurse hold an emergency restraint before getting an order?
Facility policy and state regulation set the specific window, and it is typically short, often requiring provider notification and order confirmation within a defined number of minutes to a few hours depending on the type of restraint and setting. The nurse should know and follow the exact facility protocol rather than estimate.
Does telling a patient they cannot leave the hospital count as false imprisonment?
It can, if the patient is competent, has no legal hold such as an involuntary psychiatric commitment, and is not under a physical or verbal restriction preventing them from leaving. Patients generally retain the right to leave against medical advice, and blocking that right without legal authority exposes the nurse and facility to liability.
