VEAL CHOP tells you what a deceleration means. It does not tell you what to do about it, and that is what the exam asks. Here is the full picture, including the one pattern that needs action in seconds.
Almost every nursing student learns VEAL CHOP. Far fewer can say what to do when the strip shows late decelerations, and that is the half the exam actually scores.
VEAL CHOP is a translation tool, not a care plan. It tells you what a pattern means. The item will then ask which action the nurse takes first, and the answer depends on something VEAL CHOP never mentions: whether the problem is the cord, the placenta, or neither.
This post covers the whole strip, then the actions, then the one pattern where you move in seconds rather than minutes.
The four things you read, in order
Reading a strip is a fixed sequence. Do it the same way every time and nothing gets missed.
1. Baseline rate. The average over ten minutes, excluding accelerations and decelerations. Normal is 110 to 160 bpm. Below 110 is bradycardia, above 160 is tachycardia.
2. Variability. The small beat-to-beat fluctuation in the baseline. This is the most important single feature on the strip and students routinely skim past it.
| Variability | Range | What it suggests |
|---|---|---|
| Absent | Undetectable | Serious; the key feature of Category III |
| Minimal | 5 bpm or less | Concerning; may be sleep, medication, or hypoxia |
| Moderate | 6 to 25 bpm | Reassuring. A well-oxygenated fetus |
| Marked | More than 25 bpm | Uncommon; investigate |
Moderate variability is the single most reassuring finding available. A fetus with moderate variability is very unlikely to be acidotic, even alongside some decelerations.
3. Accelerations. A rise of at least 15 bpm above baseline lasting at least 15 seconds, in a fetus of 32 weeks or more. Below 32 weeks the threshold drops to 10 by 10. Accelerations are reassuring and their presence is good news.
4. Decelerations. Now VEAL CHOP earns its keep.
VEAL CHOP, and the half nobody teaches
| Pattern | Cause | What you do |
|---|---|---|
| Variable deceleration | Cord compression | Move the patient (reposition) |
| Early deceleration | Head compression | Identify labor progress; no action needed |
| Acceleration | Okay | No action |
| Late deceleration | Placental insufficiency | Execute interventions |
The second mnemonic, MINE, is the part most students never learn, and it is where the marks are.
Telling them apart on the strip
Early decelerations mirror the contraction. They begin, bottom out and recover in step with it, a gradual U shape. The nadir lines up with the contraction peak. Cause is head compression during descent, which is normal labour. No action.
Late decelerations look similar in shape but are shifted right. The deceleration begins after the contraction has started and the lowest point comes after the peak, with recovery after the contraction ends. That shift is the whole diagnosis. Cause is uteroplacental insufficiency: the placenta cannot meet oxygen demand during the contraction.
Variable decelerations are abrupt rather than gradual, often V or W shaped, and bear no fixed relationship to contractions. Cause is cord compression.
The practical discriminator students find most useful: gradual and in sync is early, gradual and late is late, abrupt and random is variable.
What to do, by pattern
Late decelerations
This is the pattern the exam tests most, and the interventions come as a set. LION holds them:
- Left lateral repositioning, taking the uterus off the vena cava and improving placental perfusion
- IV fluids, increased
- Oxygen, 8 to 10 L by non-rebreather mask
- Notify the provider
Also stop oxytocin if it is running. Contractions are the stressor, so reducing them is part of the treatment, and an item showing late decelerations in a patient on an oxytocin infusion usually wants that discontinued.
Repositioning comes first among the nursing actions because it is immediate, free, and often sufficient. An option offering to notify the provider as the first action is usually a distractor; you intervene and notify, in that order, unless the stem makes clear nothing else is left to try.
Variable decelerations
The cause is the cord, so the fix is positional. Reposition the patient, side to side, or to knee-chest if side-lying does not resolve it. Stop oxytocin. Consider amnioinfusion if ordered, which cushions the cord.
Early decelerations
Nothing. Document and continue monitoring. The exam likes offering reassuring-sounding interventions here to see whether you will treat a normal finding.
The three-tier categories
| Category | What it looks like | Meaning |
|---|---|---|
| I | Baseline 110 to 160, moderate variability, no late or variable decelerations. Early decelerations and accelerations may be present | Normal. Routine care |
| II | Everything that is neither I nor III | Indeterminate. Evaluate, monitor, intervene as needed |
| III | Absent variability with recurrent late decelerations, or absent variability with recurrent variable decelerations, or absent variability with bradycardia, or a sinusoidal pattern | Abnormal. Prompt intervention and delivery planning |
Category II is where most real strips live, and it is deliberately broad.
For Category III, notice what every version except sinusoidal has in common: absent variability. That is the common thread. A strip with late decelerations but moderate variability is Category II, not III. Variability is what separates worrying from emergent.
A sinusoidal pattern is a smooth, regular wave with no variability, and it is its own emergency, classically associated with severe fetal anaemia.
The one that moves in seconds
Prolapsed umbilical cord. Sudden prolonged deceleration or severe variables, often immediately after membranes rupture, and the cord may be visible or palpable.
The actions, in order:
- Call for help without leaving the patient.
- Using a gloved hand, lift the presenting part off the cord and keep it lifted. This is the intervention that keeps the fetus perfused, and you do not let go until delivery.
- Position knee-chest or Trendelenburg.
- Oxygen by non-rebreather, prepare for immediate caesarean.
Do not attempt to push the cord back in. Handling it causes vasospasm and makes the hypoxia worse. If the cord is outside the body, keep it moist with warm sterile saline and leave it alone otherwise.
Any option on an exam that involves replacing the cord, or leaving the bedside to fetch help, is wrong.
Working an FHR item
- Name the deceleration first. Gradual and in sync, gradual and shifted, or abrupt.
- Translate it with VEAL CHOP to get the cause.
- Pick the action from MINE: move for variables, nothing for earlies, LION for lates.
- Before finalising, check variability. It decides urgency more than the decelerations do.
- Scan the stem for oxytocin. If it is infusing and the strip is non-reassuring, stopping it is almost always part of the answer.
The five that cost the most marks
- Treating early decelerations. They are normal.
- Notifying the provider before repositioning for late decelerations. Intervene, then notify.
- Forgetting to stop oxytocin.
- Ignoring variability and grading a strip on decelerations alone. Absent variability is what makes Category III.
- Pushing a prolapsed cord back in, or stepping away to get help.
Learn the strip as four readings in a fixed order, and the decision follows from the pattern rather than from memory.
