## Question

Review the postpartum glucose-screening timeline and determine the safest long-term follow-up response.

| Time | Data |
| --- | --- |
| Pregnancy | Gestational diabetes required insulin; the client received teaching that postpartum testing would still be needed after medication stopped. |
| 8 weeks postpartum | 75-g oral glucose tolerance test: fasting glucose 108 mg/dL and 2-hour glucose 164 mg/dL; result documented as prediabetes. |
| 18 months postpartum | No interval follow-up was scheduled; weight has increased 8 kg and A1C is 6.2%; the client reports no symptoms. |

Q1. How should the nurse interpret the overall pattern?

Persistent high diabetes risk with prediabetes and a missed prevention opportunity
Resolved pregnancy-only glucose intolerance
Normal postpartum adaptation because symptoms are absent
An isolated laboratory error that needs no follow-up

Q2. What is the best current response?

Wait until hyperglycemia symptoms appear
Restart pregnancy insulin without evaluation
Repeat screening only during a future pregnancy
Arrange diagnostic follow-up and an individualized diabetes-prevention plan

Q3. Which teaching is accurate for future surveillance?

A normal postpartum result ends screening
Lifelong diabetes screening every 1 to 3 years is still needed
A1C is always preferred during the first 12 weeks postpartum
Only clients who used insulin require follow-up

## Explanation

Gestational diabetes identifies a population at high lifelong risk for prediabetes and type 2 diabetes. A 75-g oral glucose tolerance test at 4 to 12 weeks postpartum is preferred because A1C can be less reliable early after birth. This client's postpartum result met prediabetes criteria, yet follow-up stopped while weight and A1C increased. The nurse should reconnect the client with diagnostic follow-up and an evidence-based diabetes-prevention plan, including nutrition, activity, weight, breastfeeding support when applicable, and ongoing primary care. Lifelong diabetes screening every 1 to 3 years remains necessary even after a normal result.

## In-depth explanation

Correct Answer
The trend shows an unresolved high-risk state progressing after gestational diabetes rather than a completed episode of pregnancy-only dysglycemia.

Why It Fits
The postpartum oral glucose tolerance test showed prediabetes and later A1C rose without scheduled surveillance or prevention support.

Clinical Picture
Early postpartum A1C alone may miss glucose intolerance, which is why the oral glucose tolerance test is preferred in the 4-to-12-week window.

Memory Link
Gestational diabetes ends at delivery only as a diagnosis, not as a future risk.

NCLEX Rule
Screen at 4 to 12 weeks postpartum with a 75-g oral glucose tolerance test and continue lifelong screening every 1 to 3 years.

Why the Alternatives Fail
Stopping surveillance after delivery or waiting for symptoms misses asymptomatic prediabetes and delays prevention.

## Clinical scenario

Primary care follow-up
A client required insulin for gestational diabetes and stopped insulin after delivery. The nurse reviews postpartum testing, risk counseling, and interval follow-up for type 2 diabetes prevention.

## Key concepts

- **Gestational diabetes mellitus** — Diabetes first diagnosed during pregnancy that signals increased future metabolic risk.
- **Oral glucose tolerance test** — A test that measures fasting and post-glucose-load values to identify persistent diabetes or prediabetes.
- **Prediabetes** — Glucose levels above normal but below the diabetes threshold, associated with increased progression risk.
