What action by the nurse is the most important action in preventing neonatal infection?
Standard Precautions
Good hand hygiene
Separate gown technique
Isolation of infected infants
The Correct Answer is B
Choice A: This is incorrect because Standard Precautions are a set of guidelines that apply to all patients, regardless of their infection status. They include using personal protective equipment, handling sharps and waste properly, and cleaning and disinfecting equipment and surfaces. However, they are not enough to prevent neonatal infection, as some pathogens can still be transmitted by contact or droplet.
Choice B: This is the correct answer because good hand hygiene is the most effective way to prevent the transmission of microorganisms that can cause neonatal infection. The nurse should wash their hands with soap and water or use an alcohol-based hand rub before and after touching the infant, the infant's environment, or any items that come in contact with the infant. The nurse should also educate the parents and visitors on the importance of hand hygiene and how to perform it correctly.
Choice C: This is incorrect because a separate gown technique involves wearing a clean gown for each infant and discarding it after use. This can help prevent cross-contamination between infants, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after wearing a gown, as well as before and after touching the infant or any items that come in contact with the infant.
Choice D: This is incorrect because isolation of infected infants involves placing them in a separate room or area with restricted access and using additional precautions based on the mode of transmission of the infection. This can help prevent the spread of infection to other infants, staff, or visitors, but it does not eliminate the need for hand hygiene. The nurse should still wash their hands before and after entering and leaving the isolation area, as well as before and after touching the infant or any items that come in contact with the infant.

Correct Answer is D
Explanation
Choice A) Decreased metabolic rate is incorrect because this is not a result of hypothermia in the newborn, but rather a cause of it. Metabolic rate is the speed at which the body uses energy to perform its functions. Newborns have a high metabolic rate, which helps them to maintain a normal body temperature of 36.5°C to 37.5°C (97.7°F to 99.5°F). However, some factors can lower the metabolic rate of newborns, such as prematurity, low birth weight, infection, or hypoglycemia. A low metabolic rate can make the newborn more susceptible to heat loss and hypothermia, which is a condition that occurs when the body temperature drops below 36°C (96.8°F). Therefore, this response is inaccurate and misleading.
Choice B) Decreased oxygen demands is incorrect because this is not a result of hypothermia in the newborn, but rather a consequence of it. Oxygen demand is the amount of oxygen that the body needs to function properly.
Newborns have a high oxygen demand, which helps them to support their growth and development. However, some factors can decrease the oxygen demand of newborns, such as hypothermia, sedation, or asphyxia. A low oxygen demand can impair the oxygen delivery and utilization by the tissues and organs, leading to hypoxia, acidosis, or organ failure. Therefore, this response is irrelevant and inaccurate.
Choice C) Shivering to generate heat is incorrect because this is not a result of hypothermia in the newborn, but rather a mechanism that is absent in them. Shivering is an involuntary contraction of the muscles that produces heat and raises the body temperature. It is a common response to cold exposure in adults and older children, but not in newborns. Newborns do not have the ability to shiver, as their muscles are immature and lack glycogen stores.
Instead, they rely on other methods to generate heat, such as non-shivering thermogenesis, which involves burning brown fat in certain areas of the body. Therefore, this response is irrelevant and inaccurate.
Choice D) Increased glucose demands is correct because this is a result of hypothermia in the newborn that can cause complications. Glucose demand is the amount of glucose that the body needs to produce energy and maintain its functions. Newborns have a high glucose demand, which helps them to support their metabolic rate and thermoregulation. However, some factors can increase the glucose demand of newborns, such as hypothermia, stress, or infection. A high glucose demand can deplete the glucose stores and cause hypoglycemia, which is a low level of glucose in the blood that can lead to seizures, brain damage, or death. Therefore, this response is clear and accurate.
Correct Answer is C
Explanation
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.
