What is the most significant risk factor for clubfoot?

Choice A reason:

Heat facilitates the drainage of mucus for a premature newborn. This is incorrect because heat does not affect mucus drainage. Mucus drainage is more related to suctioning and hydration.

Choice B reason:

The newborn has a small body surface for his weight. This is incorrect because a small body surface area for weight would indicate a large newborn, not a premature one. A large newborn would have less risk of heat loss than a small one.

Choice C reason:

The newborn's temperature control mechanism is immature. This is correct because premature newborns have immature thermoregulation and are prone to hypothermia. Placing the newborn in an incubator helps maintain a stable temperature and prevent further complications.

Choice D reason:

Heat increases the flow of oxygen to the newborn's extremities. This is incorrect because heat does not directly affect oxygen delivery. Oxygen delivery is more related to ventilation, perfusion, and hemoglobin levels. The question is about a premature newborn who has signs of respiratory distress, such as nasal flaring, intercostal retractions, expiratory grunting, and mild cyanosis. These signs indicate that the newborn is having difficulty breathing and may have a condition such as respiratory distress syndrome, transient tachypnea of the newborn, or meconium aspiration syndrome. The nurse should place the newborn in an incubator to provide warmth and prevent heat loss, which can worsen respiratory distress. The nurse should also monitor the newborn's vital signs, oxygen saturation, blood gases, chest x-ray, and neonatal abstinence scoring system if indicated. The nurse should be prepared to administer oxygen, surfactant, or mechanical ventilation as ordered.

Choice A reason:

A soft fundus indicates uterine atony, which is a lack of muscle tone that can lead to postpartum hemorrhage. A soft fundus is an abnormal finding and should be reported to the provider. The fundus should be firm and contracted to prevent bleeding.

Choice B reason:

A fundus that is 2 fingerbreadths above the umbilicus is too high for a client who is 12 hours postpartum. The fundus should descend about 1 centimeter per hour after delivery and should be at the level of the umbilicus at 12 hours postpartum. A high fundus could indicate retained placental fragments or a full bladder, both of which can interfere with uterine contraction and cause bleeding.

Choice C reason:

A fundus that is deviated to the right of the umbilicus is also an abnormal finding for a client who is 12 hours postpartum. A deviated fundus could indicate a full bladder, which can displace the uterus and prevent it from contracting properly. The fundus should be at the midline of the abdomen.

Choice D reason:

A fundus that is firm and at the level of the umbilicus is a normal finding for a client who is 12 hours postpartum. This indicates that the uterus is involuting (returning to its pre-pregnancy size and shape) and that there is no excessive bleeding. The nurse should expect this finding and document it accordingly.
