The nurse is caring for a 5-year-old child with impetigo contagiosa. The parents ask the nurse what will happen to their child's skin after the infection has subsided and healed. Which answer should the nurse give?

Correct Answer: A

Rationale: Impetigo contagiosa typically does not leave scarring once it has subsided and healed. This skin infection primarily affects the superficial layers of the skin and does not cause damage deep enough to result in scarring. While there may be some temporary pigmented spots or mild changes in skin color after the infection resolves, scarring is not a common outcome of impetigo contagiosa in most cases. Thus, the nurse should reassure the parents that their child's skin is not likely to have any scarring after the infection has healed.

Correct Answer: D

Rationale: Marasmus is a form of severe malnutrition characterized by a deficiency of both calories and protein in the diet. It typically occurs in young children and is often associated with a lack of adequate food intake. The classic presentation of marasmus includes extreme wasting of muscle and fat tissues, resulting in a gaunt appearance with thin limbs and a distended abdomen due to diminished muscle and subcutaneous fat. This differentiates it from kwashiorkor, another form of severe acute malnutrition characterized by edema and a protruding belly but with retained muscle mass. Therefore, option D, characterized by thin, wasted extremities and a prominent abdomen resulting from edema (ascites), accurately describes marasmus.

Correct Answer: A

Rationale: In infants with atopic dermatitis (eczema), the lesions most commonly occur on the cheeks (option A) and the extensor surfaces of the arms and legs (option C). The cheeks are a common site of involvement due to increased exposure to irritants and saliva from drooling. The extensor surfaces of the arms and legs are also frequently affected due to scratching and rubbing against clothing. While atopic dermatitis can occur in other areas such as the buttocks, back, and trunk, the cheeks and extensor surfaces are the most common locations in infants.

Correct Answer: C

Rationale: The behaviors described, such as slightly mottled skin, limp and extended extremities, hiccups, and a rapid but regular heart rate, are typical of preterm newborn behavior. Preterm infants often exhibit these characteristics due to their immature neurological and physiological systems. The mottled skin may be due to the immature vascular system, while the limp and extended extremities are common in preterm newborns as they have less muscle tone compared to full-term infants. Hiccups are also common in newborns, including preterm infants, and are generally not a cause for concern. The rapid heart rate is typical in newborns, particularly in the immediate postnatal period. Therefore, in this scenario, these behaviors are most likely related to the preterm status of the newborn rather than indicating stress, seizures, or respiratory distress.

Correct Answer: B

Rationale: Slight respiratory distress and tachycardia in a newborn during an exchange transfusion may indicate a possible transfusion reaction or overload. The first action the nurse should take is to stop the transfusion to prevent any further complications and assess the newborn's condition. After stopping the transfusion, the nurse can then take appropriate steps such as notifying the practitioner, administering medications, or providing supportive care as needed.
