Nursing process

A five-step clinical reasoning framework (assessment, diagnosis, planning, implementation, evaluation) that guides individualized nursing care and is documented and revised as the patient's condition changes.

Related: Nursing diagnosis, Evaluation
Nursing diagnosis

A clinical judgment about a patient's response to health conditions or life processes that nurses are licensed and able to treat independently, distinct from a medical diagnosis.

Evaluation

The nursing process phase in which actual outcomes are compared with expected outcomes to judge whether interventions worked and whether the care plan needs revision.

Related: High-alert medication, Medication reconciliation
High-alert medication

A drug that carries elevated risk of serious harm when misused, such as insulin, heparin, and opioids, requiring independent double-checks and standardized storage and labeling.

Related: Rights of medication administration, Medication reconciliation
Medication reconciliation

A formal process of comparing a patient's full medication list across transitions of care to identify omissions, duplications, and interactions before new orders are written.

Related: Rights of medication administration, High-alert medication
Therapeutic index

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

Related: High-alert medication, Adverse drug reaction
Adverse drug reaction

An unintended, harmful response to a medication given at a normal dose, ranging from rash and nausea to organ injury and anaphylaxis.

Related: Therapeutic index, High-alert medication
First-pass effect

Metabolism of an oral drug by the liver before it reaches systemic circulation, which reduces bioavailability and explains why oral doses often exceed intravenous doses.

Related: Therapeutic index, Adverse drug reaction
Osmolality

The concentration of dissolved particles per kilogram of fluid; serum values guide fluid replacement and are compared with urine osmolality to interpret hydration and kidney function.

Related: Third spacing, Fluid volume deficit
Third spacing

Shift of fluid into a space where it is not functionally available, such as the peritoneal cavity in ascites or burned tissue, causing edema with intravascular volume depletion.

Related: Osmolality, Fluid volume deficit
Fluid volume deficit

A state of decreased intravascular or total body water producing thirst, tachycardia, hypotension, poor skin turgor, and concentrated urine; corrected with isotonic fluids and cause-specific treatment.

Related: Osmolality, Third spacing
Mean arterial pressure

The average arterial pressure during one cardiac cycle, estimated as diastolic pressure plus one-third of the pulse pressure; values below about 65 mmHg threaten organ perfusion.

Shock

Inadequate tissue perfusion that impairs cellular oxygenation, producing altered mentation, tachycardia, hypotension, oliguria, and cool or warm skin depending on the type.
