What is the result of hypothermia in the newborn?
Decreased metabolic rate
Decreased oxygen demands
Shivering to generate heat
Increased glucose demands
The Correct Answer is D
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 A
Explanation
Choice A) Spending extra time holding and rocking the infant is correct because this is an effective and recommended nursing care for an infant with neonatal abstinence syndrome. Neonatal abstinence syndrome (NAS) is a condition that occurs when an infant is exposed to drugs such as opioids, cocaine, or alcohol in utero and goes through withdrawal after birth. NAS can cause various physical and behavioral problems in the infant, such as irritability, poor feeding, vomiting, diarrhea, sweating, fever, or seizures. Holding and rocking the infant can provide comfort, warmth, and security to the infant, as well as reduce stress and pain. It can also promote bonding and attachment between the infant and the caregiver. Therefore, this nursing care should be included in the care plan for an infant with NAS.
Choice B) Feeding the infant on a 2-hour schedule is incorrect because this is not a helpful or appropriate nursing care for an infant with neonatal abstinence syndrome. Feeding is an important aspect of caring for any infant, as it provides nutrients and calories that support growth and development. However, feeding an infant with NAS on a 2- hour schedule may not be suitable or feasible, as NAS can affect the infant's feeding ability and tolerance. An infant with NAS may have difficulty sucking, swallowing, or coordinating breathing during feeding. They may also have frequent vomiting, diarrhea, or dehydration that can interfere with feeding. Therefore, feeding an infant with NAS should be done according to their cues and needs, rather than a fixed schedule. The infant should be offered small, frequent feedings of breast milk or formula, depending on the mother's preference and availability. The infant should also be burped often and held upright after feeding to prevent aspiration or reflux.
Choice C) Positioning the infant's crib in a quiet corner of the nursery is incorrect because this is not a sufficient or optimal nursing care for an infant with neonatal abstinence syndrome. Positioning is an important aspect of caring for any infant, as it affects their comfort, safety, and development. However, positioning an infant with NAS in a quiet corner of the nursery may not be enough or beneficial, as NAS can make the infant more sensitive and responsive to environmental stimuli. An infant with NAS may be easily disturbed or overstimulated by noise, light, or movement in the nursery. They may also feel isolated or neglected if they are placed away from other infants or caregivers.
Therefore, positioning an infant with NAS should be done in a way that minimizes stimulation and maximizes interaction. The crib should be placed in a dimly lit, low noise area of the nursery, but close enough to allow frequent monitoring and contact by the nurse. The crib should also be padded with soft blankets or pillows to prevent injury from excessive movements or seizures.
Choice D) Placing stuffed animals and mobiles in the crib to provide visual stimulation is incorrect because this is not a safe or suitable nursing care for an infant with neonatal abstinence syndrome. Stimulation is an important aspect of caring for any infant, as it enhances their learning and development. However, stimulating an infant with NAS with stuffed animals and mobiles may not be appropriate or advisable, as NAS can make the infant more irritable and restless. An infant with NAS may not enjoy or tolerate visual stimulation from toys or objects in their crib. They may also become agitated or overexcited by them, which can worsen their symptoms or cause complications. Moreover, placing stuffed animals and mobiles in the crib can pose a risk of suffocation, strangulation, or injury for the infant. Therefore, stimulating an infant with NAS should be done in a way that is gentle and gradual. The nurse should use soothing techniques such as talking softly, singing lullabies, or massaging the infant's skin to calm them down. The nurse should also use simple toys such as rattles or balls to engage them in play when they are alert and interested.

Correct Answer is B
Explanation
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.
