What GTPAL Stands For

GTPAL is the standardized way to document a client’s obstetric history. Master the definitions, the counting rules, and the parity logic used on the NCLEX.

Letter	Meaning	What to Count
G — Gravida	Total number of pregnancies	Every pregnancy, including the current one, regardless of outcome
T — Term births	Births at 37 weeks or more	Each pregnancy once (twins = 1)
P — Preterm births	Births from 20 0/7 to 36 6/7 weeks	Each pregnancy once (twins = 1)
A — Abortions	Pregnancies ending before 20 weeks	Spontaneous (miscarriage) or induced; includes ectopic and molar pregnancies
L — Living children	Children currently living	Each child individually (twins = 2)

PARITY (PARA)

Parity = the number of pregnancies that reached 20 weeks or more = T + P. Whether the infant survived does not change parity.

TWO-DIGIT NOTATION: Some records use only gravida and para (for example, G3 P2), where P is the total of term and preterm births. GTPAL gives more detail about the outcome of each pregnancy.

Classify Each Pregnancy by Gestational Age

Gestational Age at End of Pregnancy	Category
Before 20 weeks	A (abortion)
20 0/7 to 36 6/7 weeks	P (preterm birth)
37 weeks or more	T (term birth)

Rules You Must Know

Count pregnancies, not babies

G, T, P, and A count pregnancies. Twins or triplets are one pregnancy.

Count babies for L

L counts each living child individually.

Include the current pregnancy

The current pregnancy always counts in G.

Gestational age decides the category

Use the gestational age at the end of the pregnancy, not the infant’s weight or survival.

Parity ignores survival

Parity = T + P, whether or not the infants are living.

Special Situations

Situation	How to Record
Current pregnancy	Counts in G only; T or P is added after delivery
Twins, triplets	One pregnancy for G, T, P, and A; each living child counts in L
Stillbirth at 20 weeks or more	T or P by gestational age; does not add to L
Neonatal or child death	No change to T or P; L decreases
Ectopic or molar pregnancy	Counts in G and A
Adopted child	Not part of GTPAL (no pregnancy); document separately

Gravida and Parity Terms

Term	Meaning
Nulligravida	Has never been pregnant
Primigravida	Pregnant for the first time
Multigravida	Has been pregnant two or more times
Nulliparous	No births at 20 weeks or more (never pregnant, or only pregnancies ending before 20 weeks)
Primiparous	One birth at 20 weeks or more
Multiparous	Two or more births at 20 weeks or more
Grand multiparous	Five or more births at 20 weeks or more

MEMORY TOOL

-gravida = pregnancies. -para / -parous = births at 20 weeks or more. Nulli = none, primi = first, multi = more than one.

NCLEX TRAP: A woman pregnant for the first time is a primigravida but still nulliparous — she becomes primiparous only after her first birth at 20 weeks or more.

One-Minute Algorithm

List all pregnancies

Include every previous pregnancy and the current one. The total is G.

Classify each completed pregnancy

T if 37 weeks or more; P if 20 0/7–36 6/7 weeks; A if before 20 weeks.

Count living children

Count each child individually. The total is L.

Calculate parity

Parity = T + P.

Double-check

Confirm that T + P + A + (1 if currently pregnant) = G.

CHECK YOUR ANSWER

For a client who is currently pregnant: T + P + A + 1 = G. For a client who is not pregnant: T + P + A = G.

Common Pitfalls

Counting twins as two under T or P.
Forgetting to include the current pregnancy in G.
Misplacing an event at the 20-week line (before 20 = A; 20 weeks or more = P or T).
Letting survival change T, P, or parity (it changes only L).
Forgetting that ectopic and molar pregnancies count in G and A.

Question 1 of 10

Why GTPAL Matters

GTPAL is more than a calculation. A history of preterm births, pregnancy losses, or many previous births helps the nurse anticipate risks such as preterm labor, cervical insufficiency, postpartum hemorrhage, and rapid labor.

Clinical Judgment Connections

Clinical Judgment	Application
Recognize Cues	Collect the full obstetric history, including gestational age at each outcome.
Analyze Cues	Classify each pregnancy correctly using GTPAL.
Prioritize Hypotheses	Identify risk factors: previous preterm births, multiple losses, grand multiparity.
Generate Solutions	Plan closer monitoring and teaching for high-risk histories.
Take Action	Document GTPAL accurately and communicate risks to the team.
Evaluate Outcomes	Update GTPAL after each birth or pregnancy outcome.

NCLEX KEY POINT

Pregnancies, not babies, for G, T, P, and A. Babies for L. Include the current pregnancy. The 20-week and 37-week lines decide the category. Parity = T + P.
