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 B
Explanation
The correct answer is choice B. Dry off the newborn.This is the priority nursing action because it prevents heat loss and hypothermia in the newborn.
The newborn has a large surface area and a thin layer of subcutaneous fat, making it vulnerable to cold stress.Drying off the newborn also stimulates breathing and crying, which helps clear the airways.
Choice A is wrong because obtaining a serum sample is not a priority action and may cause unnecessary pain and bleeding in the newborn.
Choice C is wrong because assessing the newborn’s Moro reflex is not a priority action and may be done later during the physical examination.Choice D is wrong because obtaining the newborn’s footprints is not a priority action and may be done after the bonding and breastfeeding period.
Correct Answer is D
Explanation
The correct answer is choice D. Orange juice.This is because orange juice is rich in vitamin C, which enhances the absorption of iron from ferrous sulfate tablets.Vitamin C helps reduce iron to its ferrous form, which is more readily absorbed by the intestinal cells.
Choice A is wrong because milk contains calcium, which inhibits iron absorption by forming insoluble complexes with iron.Choice
B is wrong because tea contains tannins, which are polyphenols that bind to iron and decrease its bioavailability.Choice C is wrong because water does not have any effect on iron absorption, neither enhancing nor inhibiting it.
Normal ranges for serum iron are 50-170 mcg/dL for men and 40-150 mcg/dL for women.Normal ranges for hemoglobin are 13.5-17.5 g/dL for men and 12-15.5 g/dL for women.
