CTG Drill

Rapid-fire cardiotocography under the clock — but you commit to an action, not a category.

A tracing appears. The timer runs. You don't classify it — you decide what to do. Twelve cases, a streak multiplier, and a clock you set yourself below. Because a Category II that's on oxytocin and a Category II that isn't are the same category and a different decision.

Your six commitments

1Continue monitoring — reassuring trace, no intervention
2Conservative measures — reposition, IV fluids, treat the reversible cause
3Stop / reduce oxytocin — when the uterotonic is driving it
4Acute tocolysis — terbutaline for tachysystole not from oxytocin
5Fetal scalp stimulation — elicit an acceleration to assess status
6Expedite delivery — escalate, call for help, deliver

Seconds per case

Scoring: faster correct answers score higher. Consecutive correct calls build a multiplier up to 3×. A wrong call or a timeout breaks the streak. Some near-misses earn partial credit with a nudge toward the better first move. On desktop, press 1–6.
