A nurse is providing discharge teaching to a new guardian about car seat safety.
Which of the following statements by the guardian indicates an understanding of the teaching?

Choice A rationale

Consistent crying is considered a late cue of hunger in a newborn. Crying, a complex physiological and behavioral response, requires a high expenditure of energy and is an indication that the newborn is already significantly distressed by hunger and needs to be fed immediately to avoid excessive agitation and difficulty latching.

Choice B rationale

The rooting reflex involves the newborn turning their head toward any stimulation of their cheek or mouth and opening their mouth, which is an innate physiological response critical for locating the nipple. This is a primary early hunger cue, indicating the newborn is ready and searching for a food source, initiating feeding efforts.

Choice C rationale

Sucking motions, such as rapid, repetitive sucking on the lips, tongue, or anything near the mouth, are direct early behavioral manifestations of the newborn's innate physiological need for nourishment. This action is a preparatory step for feeding, indicating readiness for oral intake and satiation of hunger.

Choice D rationale

Hand-to-mouth movements are a key early hunger cue, demonstrating the newborn's increasing drive to seek oral stimulation and food. This behavior is part of the newborn's reflexive self-soothing and exploratory repertoire, signaling a rising level of hunger before the onset of overt distress or crying.

Choice E rationale

The Babinski reflex is a normal neurological response in infants where the great toe extends upward and the other toes fan out when the sole of the foot is firmly stroked. It is a primitive reflex related to neurological development and is not an indicator of hunger or feeding readiness.

Choice A rationale

Acyclovir is an antiviral medication used primarily to treat herpes simplex virus (HSV) infections to prevent vertical transmission to the neonate. Group B Streptococcus (GBS) is a bacterium and is treated with antibiotics, specifically penicillin or ampicillin, administered intravenously during labor and delivery to prevent neonatal sepsis.

Choice B rationale

The Group B Streptococcus (GBS) culture is typically collected as a single screen between 36 weeks 0 days and 37 weeks 6 days of gestation from the lower vagina and perirectal area. This one-time positive result is sufficient to indicate the need for intrapartum antibiotic prophylaxis (IAP); repeat testing 24 hours later is not standard practice.

Choice C rationale

If the Group B Streptococcus (GBS) culture is positive, the client is considered colonized and requires intrapartum antibiotic prophylaxis (IAP), usually penicillin G, administered intravenously at the onset of labor or rupture of membranes. This reduces the risk of GBS transmission to the newborn, which can cause severe neonatal morbidity like sepsis or pneumonia.

Choice D rationale

The Group B Streptococcus (GBS) culture is a screening test obtained via a swab of the client's lower vagina and perirectal area, not a blood test. The GBS bacteria colonize these areas, and the swab is sent for culture and sensitivity to determine the need for prophylactic antibiotics during labor.
