Quick answer: VEAL CHOP pairs each fetal heart rate pattern with its cause: Variable decelerations = Cord compression, Early decelerations = Head compression, Accelerations = OK, Late decelerations = Placental insufficiency. Add MINE for the nursing response: Move the client, Identify labor progress, No intervention needed, Execute intrauterine resuscitation. A normal baseline is 110-160 bpm with moderate variability.
Fetal monitoring questions describe a strip and ask what it means and what you do first. VEAL CHOP gives the cause, the NICHD categories set the urgency, and intrauterine resuscitation tells you what to do. Definitions follow the NICHD terms used in ACOG’s October 2025 guideline.
What does VEAL CHOP stand for?
Line up the two words letter for letter. VEAL is the pattern on the strip; CHOP is its cause. MINE adds the nursing response.
| Pattern (VEAL) | Cause (CHOP) | Nursing response (MINE) |
|---|---|---|
| Variable deceleration | Cord compression | Move the client to shift pressure off the cord |
| Early deceleration | Head compression | Identify labor progress; nothing to correct |
| Acceleration | OK (fetus well oxygenated) | No intervention needed |
| Late deceleration | Placental (uteroplacental) insufficiency | Execute intrauterine resuscitation; notify the provider |
The mnemonic gives the cause, not the urgency: early decelerations and accelerations need no action, while late and recurrent variable decelerations do. For more memory aids, see our nursing mnemonics master list.
What is a normal fetal heart rate baseline and variability?
The baseline is the mean fetal heart rate (FHR) over 10 minutes, rounded to the nearest 5 bpm, excluding accelerations and decelerations. Normal is 110-160 bpm.
- Tachycardia (above 160 bpm for 10 minutes or more): maternal fever, infection or dehydration; fetal hypoxia or anemia. First, check the client’s temperature.
- Bradycardia (below 110 bpm for 10 minutes or more): maternal hypotension or hypoglycemia; cord compression or fetal hypoxia. First, confirm the monitor is recording the fetus, not the client’s pulse; ACOG notes a maternal pulse oximeter can tell them apart.
| Variability | Amplitude | What it means |
|---|---|---|
| Absent | Undetectable | Most worrying; with recurrent late or variable decelerations or bradycardia, Category III |
| Minimal | 5 bpm or less | Sleep cycle (20-40 minutes), opioids, magnesium sulfate or hypoxia |
| Moderate | 6-25 bpm | Normal; strongly predicts normal fetal acid-base status at that moment. |
| Marked | More than 25 bpm | Category II; may reflect hypoxic stress. |
Accelerations are abrupt rises of at least 15 bpm lasting at least 15 seconds at 32 weeks or later (10 bpm for 10 seconds before 32 weeks).
How do you tell early, late, variable and prolonged decelerations apart?
Check how fast the rate falls and when its lowest point (nadir) occurs. Gradual means 30 seconds or more from onset to nadir; abrupt means less. Recurrent means with half or more of contractions in 20 minutes.
| Deceleration | Shape and timing | Common causes | Nurse’s first action |
|---|---|---|---|
| Early | Gradual; mirrors the contraction, nadir at its peak | Head compression during descent | None needed; document and keep monitoring |
| Late | Gradual; nadir after the contraction peak | Oxytocin tachysystole, maternal hypotension (epidural, supine position), preeclampsia, abruption | Stop oxytocin if infusing; side-lying position, IV bolus, notify the provider |
| Variable | Abrupt V, U or W; drops 15 bpm or more for 15 seconds to under 2 minutes | Cord compression: nuchal cord, low amniotic fluid, rupture of membranes, cord prolapse | Reposition; if recurrent, notify the provider (amnioinfusion may be ordered) |
| Prolonged | Drops 15 bpm or more for 2 to under 10 minutes | Epidural hypotension, tachysystole, cord prolapse, abruption, uterine rupture | Call for help, start resuscitation, assess for cord prolapse |
On the exam these patterns come paired with oxytocin, epidurals, preeclampsia and abruption, all covered in our NCLEX maternity and OB review.
What are NICHD Category I, II and III tracings?
ACOG’s Clinical Practice Guideline No. 10 (October 2025) keeps the 2008 NICHD three-tier system. A tracing can move between categories as conditions change.
| Category | Criteria | Nursing response |
|---|---|---|
| I (normal) | Baseline 110-160 bpm, moderate variability, no late or variable decelerations; early decelerations and accelerations may be present or absent | Routine care and monitoring |
| II (indeterminate) | Anything not I or III, such as tachycardia, minimal or marked variability, recurrent late or variable decelerations without absent variability, or a prolonged deceleration | Find the cause, start intrauterine resuscitation, notify the provider, reassess |
| III (abnormal) | Absent variability with recurrent late decelerations, recurrent variable decelerations or bradycardia; or a sinusoidal pattern | Notify the provider immediately, resuscitate, prepare for expedited birth if it does not resolve |
Within Category II, ACOG treats moderate variability and accelerations as protective. Absent or persistent minimal variability, new tachycardia and recurrent decelerations are higher-risk features.
A sinusoidal pattern is a smooth sine wave in the baseline at 3-5 cycles per minute for 20 minutes or more, linked to severe fetal anemia (for example, Rh alloimmunization or fetomaternal hemorrhage). ACOG notes that beyond 30 minutes no resuscitative measure helps, so the nurse notifies the provider at once and prepares for delivery. Practice the conditions behind it with our antepartum and high-risk pregnancy practice questions.
What are the intrauterine resuscitation steps, and is oxygen still one of them?
Intrauterine resuscitation corrects whatever is reducing fetal oxygen delivery. ACOG recommends it for Category II tracings before cesarean birth and immediately for Category III.
- Stop or reduce oxytocin when contractions are too frequent. Tachysystole is more than 5 contractions in 10 minutes, averaged over 30 minutes. If tachysystole with an abnormal tracing persists after oxytocin is stopped, the provider may order a fast-acting uterine relaxant such as terbutaline.
- Reposition the client side-lying to take the uterus off the vena cava and aorta and shift pressure off the cord. Avoid supine.
- Give an IV fluid bolus of a non-glucose isotonic solution such as lactated Ringer’s, as ordered.
- Correct maternal hypotension after an epidural with position, fluids and a vasopressor if ordered.
- Notify the provider and document the fetal response.
- Prepare for the next step: amnioinfusion for recurrent variable decelerations, or expedited birth when a Category III tracing does not improve.
Where does maternal oxygen fit now?
Older NCLEX prep resources list oxygen by nonrebreather mask at about 10 L/min as a routine step for late decelerations. ACOG’s 2025 guideline now recommends against routine maternal oxygen for Category II or III tracings in the absence of maternal hypoxia (strong recommendation, high-quality evidence). A 2021 meta-analysis of 16 randomized trials found no improvement in umbilical artery pH, Apgar scores or NICU admissions. Oxygen is still given for maternal hypoxia. AWHONN questioned ACOG’s earlier 2022 advisory, so follow unit protocol in practice.
On the exam: if the client’s oxygen saturation is normal, oxygen is not the first action; choose the step that removes the cause.
What does the nurse do first for emergencies?
- Prolonged deceleration or bradycardia: confirm the rate is fetal, call for help, start resuscitation and look for the cause.
- Prolapsed cord: call for help and lift the presenting part off the cord with a gloved hand. Position the client knee-chest or head-down, handle the cord as little as possible, and prepare for emergency birth.
- Sinusoidal pattern or unresolved Category III: notify the provider immediately and prepare for expedited birth.
After birth, review APGAR and GTPAL scoring, then try our newborn and postpartum practice questions and the maternity NCLEX practice set.
Sample question 1
A client at 39 weeks of gestation is receiving an oxytocin infusion. At 1015, the nurse notes that the client has averaged 7 contractions every 10 minutes over the past 30 minutes. The fetal heart rate baseline is 145/min with minimal variability and recurrent late decelerations. The client’s oxygen saturation is 99% on room air. Which action should the nurse take first?
- Discontinue the oxytocin infusion
- Increase the rate of the primary IV infusion
- Apply oxygen at 10 L/min by nonrebreather mask
- Assist the client into a supine position
Show answer & rationale
Correct answer: A. Seven contractions in 10 minutes is tachysystole, and recurrent late decelerations show the placenta cannot restore fetal oxygen between contractions. Stopping the oxytocin removes the cause. Option C is incorrect because saturation is normal, and ACOG recommends against routine maternal oxygen without hypoxia. Option B is a valid step but does not stop the contractions driving the pattern. Option D is incorrect because lying supine compresses the vena cava and aorta and further reduces uterine blood flow.
Sample question 2
The nurse reviews the fetal heart rate tracing of a client in active labor whose cervix is dilated 7 cm. The baseline is 135/min with moderate variability. With each contraction, the rate slows gradually to 120/min, reaches its lowest point at the peak of the contraction, and returns to baseline as the contraction ends. Which action is most appropriate?
- Turn the client to a lateral position and give an IV bolus
- Notify the provider of a Category III tracing
- Prepare the client for an amnioinfusion
- Continue monitoring and document the findings
Show answer & rationale
Correct answer: D. A gradual deceleration that mirrors the contraction is an early deceleration from head compression. With a normal baseline and moderate variability, the tracing is Category I, so routine monitoring is correct. Option A treats uteroplacental insufficiency, which is not present. Option B misclassifies the tracing; Category III requires absent variability with recurrent decelerations or bradycardia, or a sinusoidal pattern. Option C is used for recurrent variable decelerations.
Sample question 3
A client in active labor with a cervix dilated 6 cm has had ruptured membranes for 4 hours. No oxytocin is infusing. The fetal heart rate baseline is 140/min with moderate variability. With most contractions, the rate drops abruptly to 90/min in a V shape, lasts about 40 seconds, and returns quickly to baseline. Which action should the nurse take first?
- Document the pattern as expected head compression
- Assist the client to a side-lying position
- Prepare the client for an immediate cesarean birth
- Request a prescription for an amnioinfusion
Show answer & rationale
Correct answer: B. Abrupt, V-shaped drops with most contractions are recurrent variable decelerations from cord compression. With moderate variability this is Category II, and a position change is the first step to move pressure off the cord. Option A is incorrect because early decelerations are gradual and mirror the contraction. Option C is premature because variability is moderate and the pattern may respond to repositioning. Option D, an amnioinfusion, may be used if the decelerations persist, but repositioning comes first and can be done right away.
Sample question 4 (Select all that apply)
At 1430, the nurse assesses a client in labor who is receiving an oxytocin infusion and had epidural analgesia placed 20 minutes ago. Vital signs are blood pressure 84/48 mm Hg, heart rate 108/min, temperature 99.1°F (37.3°C), and oxygen saturation 98% on room air. The fetal heart rate baseline is 150/min with absent variability and recurrent late decelerations. Which actions should the nurse take? Select all that apply.
- Prepare the client for an amnioinfusion
- Stop the oxytocin infusion
- Turn the client to a lateral position
- Give an IV bolus of lactated Ringer’s as prescribed
- Notify the provider and prepare for expedited birth
- Place the client supine to improve venous return
Show answer & rationale
Correct answers: B, C, D, E. Absent variability with recurrent late decelerations is Category III, and post-epidural hypotension is reducing uterine blood flow. Stopping oxytocin (B) removes contraction stress, a lateral position (C) relieves pressure on the vena cava and aorta, and an IV bolus (D) treats the hypotension. Category III calls for immediate notification and preparation for expedited birth if resuscitation fails (E). Option A, amnioinfusion, is used for recurrent variable decelerations from cord compression, not late decelerations from reduced uterine blood flow. Option F is incorrect because lying supine compresses the vena cava and lowers venous return.
Frequently Asked Questions
What does VEAL CHOP stand for?
VEAL CHOP matches fetal heart rate patterns to their causes: variable decelerations mean cord compression, early decelerations mean head compression, accelerations are OK, and late decelerations mean placental insufficiency.
What does MINE mean in VEAL CHOP MINE?
MINE is the nursing response to each pair: Move the client for variable decelerations, Identify labor progress for early decelerations, No intervention for accelerations, and Execute intrauterine resuscitation for late decelerations.
What is a normal fetal heart rate?
A normal baseline fetal heart rate is 110-160 beats per minute with moderate variability of 6-25 bpm. A baseline above 160 bpm for 10 minutes or more is tachycardia, and below 110 bpm is bradycardia.
Do nurses still give oxygen for late decelerations?
Not routinely. ACOG’s October 2025 guideline recommends against routine maternal oxygen for Category II or III tracings unless the client is hypoxic, because trials showed no improvement in umbilical artery pH or newborn outcomes. On the exam, choose the action that removes the cause.
What is the first action for late decelerations?
If oxytocin is infusing, stop it first, because oxytocin-driven contractions reduce placental blood flow. Then turn the client side-lying, give an IV fluid bolus as ordered, correct any hypotension, and notify the provider.
