One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because
It produces a prolapsed cord.
It increases maternal renal blood flow.
It decreases maternal blood pressure.
There is a reduction of placental blood flow.
The Correct Answer is A
Choice A reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it causes a reduction of placental blood flow. Placental blood flow is essential for delivering oxygen and nutrients to the fetus and removing waste products. Hypertonic contractions are too frequent, too long, or too strong, and they can reduce the time for the placenta to refill with blood between contractions. This can lead to fetal hypoxia, acidosis, and distress.
Choice B reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it produces a prolapsed cord. This is incorrect because a prolapsed cord is not caused by hypertonic contractions, but by other factors such as a low-lying placenta, a premature rupture of membranes, a small or preterm fetus, or an abnormal presentation. A prolapsed cord occurs when the umbilical cord slips through the cervix and into the vagina before or during delivery. This can compress the cord and cut off the blood supply to the fetus, resulting in fetal bradycardia and possible death.
Choice C reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it increases maternal renal blood flow. This is incorrect because hypertonic contractions do not affect maternal renal blood flow directly. Maternal renal blood flow is influenced by factors such as maternal blood pressure, hydration, cardiac output, and renal function. Hypertonic contractions may cause maternal dehydration, which can reduce renal blood flow, but this is not a direct effect of oxytocin stimulation.
Choice D reason:
One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it decreases maternal blood pressure. This is incorrect because hypertonic contractions do not cause maternal hypotension, but rather hypertension. Hypertension is a common side effect of oxytocin stimulation, as oxytocin causes vasoconstriction and increases the sensitivity of the vascular smooth muscle to catecholamines. Hypertension can lead to complications such as preeclampsia, eclampsia, and placental abruption.

Correct Answer is D
Explanation
The correct answer is: d. Move infant away from blowing fan.
Choice A: Dry the baby after a bath
Drying the baby after a bath is essential to prevent heat loss through evaporation. When a newborn is wet, the water on their skin can evaporate, taking heat away from their body. While this is an important step in maintaining the baby’s temperature, it does not specifically address heat loss through convection.
Choice B: Wrap the baby in warmed blankets
Wrapping the baby in warmed blankets helps prevent heat loss through conduction and radiation. Conduction occurs when the baby comes into contact with a cooler surface, and radiation occurs when the baby loses heat to the surrounding environment. Although this action is beneficial, it does not directly address heat loss through convection.
Choice C: Place the baby in a warmer
Placing the baby in a warmer is an effective way to maintain the baby’s overall body temperature by providing a controlled, warm environment. This action helps prevent heat loss through conduction, radiation, and evaporation. However, it is not the most direct method to prevent heat loss through convection.
Choice D: Move infant away from blowing fan
Moving the infant away from a blowing fan directly addresses and prevents heat loss due to air movement, which is a key factor in convection. Convection occurs when air currents carry heat away from the baby’s body. By moving the baby away from the fan, the nurse can effectively reduce heat loss through this mechanism.
Correct Answer is D
Explanation
Choice A reason:
10% to 15% of their birth weight. This is incorrect because this range is too high for a normal newborn weight loss. Losing more than 10% of their birth weight may indicate dehydration, inadequate feeding, or other problems. • Choice B reason:
20% of their birth weight. This is incorrect because this percentage is way too high for a normal newborn weight loss. Losing 20% of their birth weight would be a serious sign of illness or malnutrition. • Choice C reason:
15% to 18% of their birth weight. This is incorrect because this range is also too high for a normal newborn weight loss. Losing 15% to 18% of their birth weight would be a cause for concern and require further evaluation. • Choice D reason:
5% to 10% of their birth weight. This is correct because this range is within the normal limits for a newborn weight loss. Newborns lose some weight as a result of insufficient caloric intake, fluid loss, and metabolic adjustments in the first week after birth. They usually regain their birth weight by the second week.
