The nurse reinforces teaching regarding newborn hypoglycemia.
Which of the following client statements indicate understanding of newborn hypoglycemia? Select all that apply.
Glucose levels of 40 to 45 mg/dL are considered the normal lower limit for up to 72 hours after birth.
If my baby's blood glucose keeps going below 50 mg/dL in the next 24 hours, they will need intravenous glucose.
When my umbilical cord was clamped, my baby lost its source of glucose.
As long as I breastfeed my baby frequently, their blood glucose levels should improve.
It is common for term newborns to experience transient hypoglycemia within the first few hours of life.
The skin-to-skin contact immediately after birth promotes thermoregulation and stabilizes glucose levels.
Correct Answer : C,D,E,F
Choice A rationale
Neonatal hypoglycemia is typically defined as a blood glucose concentration below 40 mg/dL in the first 4 hours of life, or below 45 mg/dL between 4 and 24 hours. Glucose levels of 40 to 45 mg/dL are generally considered the goal range to prevent neurological injury, not the normal lower limit for up to 72 hours post-birth.
Choice B rationale
If a newborn's blood glucose levels remain persistently below 40 mg/dL after initial management (like feeding) or if they develop symptomatic hypoglycemia, intravenous dextrose will be required. A value persistently below 50 mg/dL is concerning, but the 40 mg/dL threshold is often the critical point for initiating IV glucose when oral methods fail.
Choice C rationale
The umbilical cord provides the fetus with a continuous supply of glucose via the placenta from the mother. Upon umbilical cord clamping, this maternal glucose supply is abruptly interrupted, requiring the newborn's immature metabolic systems to take over glucose homeostasis. This sudden loss of exogenous glucose is a primary factor in transient newborn hypoglycemia.
Choice D rationale
Frequent breastfeeding provides the newborn with a readily available source of lactose, which is metabolized into glucose, thereby promoting the stability of their blood glucose levels. Early and frequent feeding is the primary intervention for transient hypoglycemia in newborns who are able to feed, utilizing the oral route for caloric intake.
Choice E rationale
Transient hypoglycemia is a common and expected physiological adaptation in term newborns during the initial hours after birth. The abrupt cessation of maternal glucose supply necessitates the newborn's activation of gluconeogenesis and glycogenolysis, which may temporarily be insufficient, leading to a mild, self-limiting drop in blood glucose.
Choice F rationale
Skin-to-skin contact immediately after birth is vital as it prevents cold stress. When a newborn is cold, they must expend energy (calories) to produce heat, which consumes glucose, potentially leading to or exacerbating hypoglycemia. Thermoregulation thus indirectly stabilizes blood glucose levels by conserving energy.

Correct Answer is ["B","E"]
Explanation
Choice A rationale
The instruction to avoid urinating at bedtime is incorrect and potentially harmful. Urinary stasis (urine sitting in the bladder) is a major risk factor for bacterial growth and recurrence of a urinary tract infection (UTI). Complete and frequent bladder emptying, including right before bed, is essential to flush out potential pathogens and prevent the ascent of bacteria, thereby minimizing the opportunity for bacterial proliferation within the urinary tract.
Choice B rationale
Wearing cotton-crotch underwear is recommended because cotton is highly breathable and absorbent, promoting air circulation and minimizing moisture retention in the perineal area. A dry environment inhibits the growth of bacteria and yeast, which can ascend into the urethra, potentially leading to a recurrent urinary tract infection (UTI). Synthetic fabrics trap heat and moisture, creating a more favorable medium for pathogen proliferation.
Choice C rationale
The instruction to eliminate yogurt products from the diet is incorrect. Yogurt containing live and active cultures (probiotics, such as Lactobacillus) can actually be beneficial. These beneficial bacteria may help maintain the normal balance of flora, especially in the vagina and surrounding area, which can inhibit the overgrowth of pathogenic bacteria (E. coli) that commonly cause urinary tract infections.
Choice D rationale
Douching is generally discouraged as it can disrupt the normal vaginal flora (primarily Lactobacillus), altering the protective acidic pH (normal 3.5-4.5). This disruption can increase the risk of both vaginal infections and ascending infections that may lead to a recurrent urinary tract infection (UTI). The vagina is a self-cleaning organ, and douching can inadvertently push bacteria higher into the reproductive or urinary tracts.
Choice E rationale
Refraining from taking bubble baths is a correct instruction. Soaps, detergents, and chemicals in bubble baths can cause irritation to the urethral meatus and surrounding tissues. This irritation makes the area more susceptible to colonization by bacteria, such as those from the perianal region, which can then ascend the urethra and lead to the development or recurrence of a urinary tract infection (UTI).
Correct Answer is C
Explanation
Choice A rationale
Identifying that the newborn resembles oneself as a baby is a normal and positive aspect of maternal-infant attachment and bonding, representing the "taking-hold" phase of postpartum psychological adjustment, where the mother focuses on the infant and parental role. This demonstrates integration and is not considered a psychosocial concern warranting intervention, indicating healthy psychological adaptation.
Choice B rationale
Reporting fatigue and a desire to sleep is a physiological and expected finding in the immediate postpartum period, largely due to the physical exertion of labor, blood loss, and hormonal shifts. While rest is important, this is considered a normal physical adjustment and not a primary psychosocial concern indicative of maladaptation or mental health issues, unlike severe mood or attachment disturbances.
Choice C rationale
A lack of desire to feed the newborn can signify impaired maternal-infant bonding, emotional withdrawal, or a potential symptom of postpartum mood disorders, such as postpartum depression, which is a significant psychosocial concern. This finding deviates from the expected "taking-hold" phase where the mother is typically focused on caring for and interacting with the infant, necessitating further psychosocial assessment.
Choice D rationale
Discussing a desire to have more children is a normal expression of future family planning and generally indicates a positive, healthy adaptation to the current newborn and the role of motherhood. This thought process does not suggest any immediate psychosocial concern or distress and reflects forward-looking reproductive health considerations and positive family construction.
