The difference between physiological and nonphysiological jaundice is that nonphysiological jaundice

Choice a) Have the parent fold the infant's arms across the chest is incorrect because this is not a helpful way to calm a preterm infant. Folding the arms across the chest can restrict the infant's breathing and movement, and may increase their stress and discomfort. Preterm infants need gentle and supportive touch, not restraint or pressure.

Choice b) Encourage the parent to place the infant back in the warmer is incorrect because this is not a necessary or beneficial action for a preterm infant who is showing signs of overstimulation. Placing the infant back in the warmer can interrupt the bonding and attachment process between the parent and the infant, and may make the infant feel more isolated and insecure. Preterm infants need close and frequent contact with their parents, not separation or detachment.

Choice c) Encourage the parent to do kangaroo care is correct because this is an effective and evidence-based method of soothing and stabilizing a preterm infant who is experiencing overstimulation. Kangaroo care is a technique where the parent holds the infant skin-to-skin on their chest, providing warmth, comfort, and security. Kangaroo care can reduce the infant's stress hormones, lower their heart rate and blood pressure, improve their oxygenation and breathing, enhance their growth and development, and strengthen their bond with their parent.

Choice d) Cover the infant with a warm bed blanket is incorrect because this is not a sufficient or optimal way to comfort a preterm infant who is displaying signs of overstimulation. Covering the infant with a warm bed blanket can provide some warmth and protection, but it does not offer the same benefits as kangaroo care. A warm bed blanket cannot mimic the parent's heartbeat, voice, smell, and movement, which are essential for the infant's emotional and physiological well-being. Preterm infants need human touch and interaction, not just physical warmth.

Choice A: This is incorrect because pointing out how lucky she is to have a healthy baby may invalidate her feelings and make her feel guilty or ashamed. The nurse should acknowledge and respect the client's emotions and avoid making judgments or comparisons.

Choice B: This is incorrect because assessing her for pain is not the first action that the nurse should take. Although pain may be a factor that contributes to the client's emotional state, it is not the primary cause of her crying. The nurse should first establish rapport and trust with the client and then assess her physical and psychological needs.

Choice C: This is incorrect because explaining that she is experiencing postpartum blues may be premature and inaccurate. Postpartum blues are mild and transient mood changes that occur in up to 80% of women within the first few days after childbirth. They are characterized by tearfulness, irritability, anxiety, and mood swings. However, the nurse should not assume that the client has postpartum blues without performing a thorough assessment and ruling out other possible causes of her crying, such as postpartum depression, anxiety, or trauma.

Choice D: This is the correct answer because allowing her time to express her feelings is the most appropriate and empathetic action that the nurse should take first. The nurse should listen actively and attentively to the client and provide emotional support and reassurance. The nurse should also use open-ended questions and reflective statements to facilitate communication and explore the client's concerns and coping strategies.
