A nurse is teaching a new parent how to correctly use a car seat.
Which of the following statements by the parent indicates an understanding of the teaching?

Placement of an internal fetal spiral electrode is contraindicated because it requires ruptured membranes and no active vaginal bleeding. In cases of antepartum bleeding, especially without rupture of membranes, it increases infection risk and fetal injury.

Laboratory testing (CBC, blood type, Rh factor, coagulation studies) is anticipated to evaluate maternal blood loss, anemia, blood type compatibility, and coagulation status. These are essential for managing bleeding risk and potential transfusions.

IV fluids are anticipated to maintain maternal hemodynamic stability and manage possible blood loss, preventing hypovolemia and hypotension.

Abdominal ultrasound is anticipated for placental localization, fetal wellbeing assessment, and to differentiate causes of bleeding (placenta previa vs. abruption).

Betamethasone administration is anticipated at 30 weeks to accelerate fetal lung maturity in case of preterm delivery.

Continuous fetal heart rate (FHR) monitoring is essential to assess fetal status and detect hypoxia or distress promptly.

Digital cervical exam is contraindicated due to risk of exacerbating bleeding and infection in the presence of unknown placental position or bleeding source.

Choice A rationale

Initiating feeding on the less sore breast is generally recommended when nipples are sore or cracked. The newborn's initial suck is often the strongest and most vigorous, which can exacerbate pain and damage on an already compromised nipple. Starting on the less sore side allows for a gentler initial latch and flow.

Choice B rationale

Using breast pads with a moisture-proof lining can trap moisture against the nipples, creating a warm, damp environment that promotes bacterial or fungal growth, potentially worsening soreness or leading to infection. Air drying and absorbent, breathable pads are generally preferred for nipple healing.

Choice C rationale

Reducing feeding frequency can lead to breast engorgement, which further complicates breastfeeding and can decrease milk supply. Frequent, shorter feedings are often more comfortable for the mother and help maintain milk production while allowing the nipples to heal gradually.

Choice D rationale

Applying colostrum to the nipples after feeding is beneficial due to its immunological properties and moisturizing effect. Colostrum contains antibodies and growth factors that can promote healing, reduce inflammation, and provide a protective barrier against infection, aiding in the recovery of sore and cracked nipples.
