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 B
Explanation
A. Pyelonephritis in pregnancy does not pose any risks to the fetus. Pyelonephritis can lead to complications such as preterm labor, low birth weight, and maternal sepsis, making this statement incorrect.
B. Untreated pyelonephritis in pregnancy can increase the risk of preterm labor and low birth weight. Pyelonephritis can cause systemic inflammation, leading to complications such as preterm labor and fetal growth restriction. Prompt treatment is necessary to reduce these risks.
C. Pyelonephritis is a common condition during pregnancy. While urinary tract infections (UTIs) are common in pregnancy, pyelonephritis (kidney infection) is less frequent but more serious.
D. Pyelonephritis is a mild infection that does not require treatment. Pyelonephritis is a serious condition that requires immediate antibiotic therapy to prevent maternal and fetal complications.
Correct Answer is D
Explanation
A. To determine the exact gestational age of the fetus. Gestational age is estimated via ultrasound and fundal height, not an NST.
B. To measure the amniotic fluid volume. Amniotic fluid volume is assessed with an ultrasound and amniotic fluid index (AFI), not an NST.
C. To confirm the presence of labor contractions. An NST does not confirm labor contractions; it evaluates fetal heart rate in response to fetal movement.
D. To assess fetal well-being in cases of suspected fetal growth restriction. An NST evaluates fetal oxygenation and well-being, making it useful in cases of intrauterine growth restriction (IUGR) or other concerns about fetal health.
