Related: Informed consent, Do-not-resuscitate order
Informed consent

The client's voluntary agreement to a procedure or treatment after receiving and understanding information about its purpose, risks, benefits, and alternatives; the nurse verifies understanding and witnesses the signature rather than obtaining consent.

Health literacy

A client's ability to obtain, process, and understand basic health information to make appropriate decisions; low health literacy calls for plain language, teach-back, and avoidance of jargon.

Related: Teach-back method, Motivational interviewing
Teach-back method

A teaching technique in which the client explains or demonstrates the information in their own words, allowing the nurse to confirm understanding and reteach rather than simply asking whether the client understood.

Related: Health literacy, Motivational interviewing

Attending fully to a client's words and behavior, using eye contact, posture, and brief encouragers, then reflecting back the content and feeling to confirm understanding.

Related: Therapeutic communication, Nontherapeutic response
Nontherapeutic response

A communication behavior that blocks client expression, such as false reassurance, giving advice, changing the subject, judging, or asking why, which shifts focus away from the client's experience.

Related: Therapeutic communication, Active listening
Defense mechanism

An unconscious mental strategy that reduces anxiety by distorting reality, such as denial, projection, rationalization, or displacement; adaptive in the short term, but problematic when it prevents needed care.

Related: Therapeutic communication, Grief process

The emotional and behavioral response to loss, commonly described through stages or tasks including denial, anger, bargaining, depression, and acceptance; expressions vary widely across cultures and individuals.

Related: Defense mechanism, Therapeutic communication

Pharmacokinetics

How the body handles a drug through absorption, distribution, metabolism, and excretion; changes in organ function alter these processes and can cause drug accumulation or toxicity.

Related: Therapeutic index, First-pass effect
Therapeutic index

The ratio between a drug's toxic dose and its effective dose; a narrow index means small dose changes or altered clearance can produce toxicity, so serum levels are monitored closely.

Related: Pharmacokinetics, Peak and trough levels
Peak and trough levels

Serum drug concentrations drawn to guide dosing of drugs with narrow therapeutic ranges; the trough is drawn just before the next dose and the peak at a specified time after it.

Related: Therapeutic index, Pharmacokinetics

A state in which extracellular fluid is lost or inadequate, producing thirst, tachycardia, hypotension, decreased urine output, and poor skin turgor; treatment replaces fluid and corrects the cause.

Related: Intake and output, Daily weight
Fluid volume excess

A state of expanded extracellular fluid, often from heart or kidney failure or excessive sodium intake, producing edema, weight gain, crackles, and dyspnea; treatment restricts fluid and sodium and promotes diuresis.

Related: Intake and output, Daily weight
Orthostatic hypotension

A drop in blood pressure on standing, commonly at least 20 mmHg systolic or 10 mmHg diastolic, causing dizziness and fall risk; clients are taught to rise slowly and are assessed before ambulation.
