A 45-year-old woman at 36-weeks gestation presents for a nonstress test.

Comprehensive and Detailed Explanation From NCC-Aligned Sources:

The NST strip shows:

Baseline FHR about 140 bpm

Moderate variability

Two or more accelerations meeting 15×15 criteria

No decelerations

Normal, infrequent contractions

Per NCC and AWHONN, a reactive NST is defined as:

≥2 accelerations of 15 bpm × 15 seconds in a 20-minute period

With baseline 110–160 and moderate variability

No recurrent decelerations

A reactive NST at 36 weeks in a hemodynamically stable mother with normal vitals is reassuring, and the appropriate disposition is routine follow-up and discharge.

Why the other options are incorrect:

B. Induce labor – Not indicated solely on maternal age or a reactive NST.

C. Kleihauer-Betke test – Used to quantify fetomaternal hemorrhage after trauma or sensitization risk; there is no such history here.

Therefore, the correct action is A. Discharge home.
