A nurse caring for a patient in labor is evaluating the fetal heart monitor.Which finding would indicate fetal distress?
The fetal heart rate decreases after the start of a contraction and returns to the baseline 60 seconds after the end of the contraction.
There is a six to ten beat-to-beat variability in the fetal heart rate.
The fetal heart rate accelerates five to seven beats just prior to the beginning of a contraction.
The fetal heart rate decreases at the start of the contraction and returns to baseline by the end of the contraction.
The Correct Answer is A
The correct answer is choice A and it indicates fetal distress because it is a sign of late deceleration. Late decelerations are due to uteroplacental insufficiency as the result of decreased blood flow and oxygen to the fetus during the uterine contractions. This causes hypoxemia and can lead to fetal acidosis and neurological damage.
Choice B is wrong because it indicates a normal variability in the fetal heart rate, which reflects a healthy autonomic nervous system. A normal fetal heart rate is 120-160 beats per minute.
Choice C is wrong because it indicates an early acceleration in the fetal heart rate, which is a benign finding that may occur with fetal movement or stimulation.
Choice D is wrong because it indicates an early deceleration in the fetal heart rate, which is a normal response to fetal head compression during contractions.
It does not indicate fetal distress.
Normal ranges for fetal heart rate patterns are:
• Baseline: 120-160 beats per minute
• Variability: 6-25 beats per minute
• Accelerations: at least 15 beats per minute above baseline for at least 15 seconds
• Decelerations: none or early (mirror contractions)

Correct Answer is A
Explanation
The correct answer is choice A. A breastfed baby is likely to gain weight more rapidly in the first month of life.This statement is wrong because breastfed babies generally gain weight faster than formula-fed babies for the first 3 months of life.They also double their birth weight by 3-4 months and triple it by one year.
Therefore, a breastfed baby’s weight gain in the first month of life is not unusual or concerning.
Choice B is correct because breastfeeding is not a reliable method of birth control.A woman can still ovulate and become pregnant while breastfeeding, especially if she feeds her baby less frequently or supplements with formula or solids.
Choice C is correct because breastfeeding has been shown to reduce the risk of allergies in babies.Breast milk contains antibodies and other immune factors that protect the baby from infections and allergic reactions.
Choice D is correct because breastfeeding mothers need to drink enough fluids to stay hydrated and produce enough milk.The recommended fluid intake for breastfeeding mothers is about 13 cups (3 liters) per day.
Correct Answer is B
Explanation
he correct answer is choice B. Sufficient perfusion and circulation of the fetus.This is because the fetal heart rate is within the normal range of 110 to 160 beats per minute, and there is moderate beat-to-beat variability, which indicates a healthy nervous system.
Choice A is wrong because insufficient perfusion of the placenta would cause fetal distress and abnormal fetal heart rate patterns, such as late decelerations or minimal variability.
Choice C is wrong because maternal hypoxia would not directly affect the fetal heart rate, unless it leads to placental insufficiency or uterine hyperstimulation.
Choice D is wrong because fetal hypoxia would cause signs of fetal distress, such as tachycardia, bradycardia, or absent variability.
