A nurse receives a report about a client who is in labor and is having contractions 3 min apart. Which of the following patterns should the nurse expect on the fetal monitoring tracing?
Contractions that last for 60 seconds each with a 2-min rest between contractions
Contractions that last for 60 seconds each with a 3-min rest between contractions
A contraction that lasts 3 min followed by a period of relaxation
Contractions that last 45 seconds each with a 2-min rest between contractions
The Correct Answer is A
A. Contractions that last for 60 seconds each with a 2-min rest between contractions. If contractions are 3 minutes apart, this means the interval from the start of one contraction to the start of the next is 3 minutes. If each contraction lasts for 60 seconds, there will be a 2-minute rest period before the next contraction begins.
B. Contractions that last for 60 seconds each with a 3-min rest between contractions. This would indicate contractions occurring every 4 minutes, not every 3 minutes.
C. A contraction that lasts 3 min followed by a period of relaxation. A contraction lasting 3 minutes is abnormal and suggests uterine tachysystole, which can be dangerous.
D. Contractions that last 45 seconds each with a 2-min rest between contractions. If contractions last 45 seconds, the remaining rest period would be 2 min 15 sec, not exactly 2 minutes.

Correct Answer is A
Explanation
A. "I need to lie flat on my back to perform the procedure." Lying flat on the back can cause supine hypotension syndrome due to compression of the inferior vena cava. The client should lie on her left side or sit in a comfortable position to improve placental circulation.
B. “If I count fewer than 10 kicks in a 2-hour period, I would count the kicks again over the next 2 hours." If fewer than 10 movements are felt in 2 hours, the client should rest, eat, and try counting again. If movements remain low, she should contact her provider.
C. "I need to place my hands on the largest part of my abdomen and concentrate on the fetal movements to count the kicks." Placing hands on the abdomen helps the client feel subtle fetal movements.
D. “I will record the number of movements or kicks." Keeping a record of fetal movements helps monitor fetal well-being.
Correct Answer is A
Explanation
A. Variable decelerations are due to umbilical cord compression. Variable decelerations are characterized by abrupt decreases in FHR, often with a "V" or "U" shape. They are caused by umbilical cord compression, which disrupts fetal oxygenation.
B. Variable decelerations are a result of the administration of IV narcotic analgesics. Narcotic analgesics (e.g., morphine, fentanyl) cause decreased FHR variability and prolonged decelerations, not variable decelerations.
C. Variable decelerations are caused by uteroplacental insufficiency. Uteroplacental insufficiency causes late decelerations, not variable decelerations.
D. Variable decelerations are related to fetal head compression. Fetal head compression causes early decelerations, which are gradual and mirror contractions, unlike variable decelerations.
