A nurse is reinforcing teaching with the mother of a newborn about the proper use of a bulb syringe for suctioning.
Which of the following instructions should the nurse include in the teaching?
Lubricate the bulb with sterile water prior to use.
Depress the bulb prior to insertion.
Place the bulb in the center of the newborn's mouth.
Suction the newborn's nose first, then the mouth.
The Correct Answer is B
Choice A rationale
Lubricating the bulb syringe with sterile water is unnecessary and could introduce fluid into the newborn's airway or mouth, potentially causing aspiration. The bulb syringe is designed for mechanical suctioning and does not require lubrication for effective and safe use in clearing secretions from the newborn's mouth and nose.
Choice B rationale
Depressing the bulb prior to insertion creates a negative pressure or vacuum within the syringe. This action allows for effective suctioning of secretions when the bulb is released after insertion into the newborn's mouth or nose, ensuring that mucus is drawn into the syringe for removal.
Choice C rationale
Placing the bulb in the center of the newborn's mouth could stimulate the gag reflex, potentially causing vomiting or aspiration of secretions. The bulb syringe should be inserted into the side of the newborn's mouth, between the cheek and gums, to facilitate effective suctioning without triggering an adverse response.
Choice D rationale
Suctioning the newborn's nose first, then the mouth, is an incorrect sequence. The mouth should always be suctioned first to prevent the newborn from aspirating any oral secretions into the lungs if they gasp or inhale after nasal suctioning, ensuring a clear airway before nasal passages are addressed.

Correct Answer is D
Explanation
Choice A rationale
Light strokes on the abdomen with rhythmic breathing, known as effleurage, are a distraction technique during labor. This method stimulates large-diameter nerve fibers, competing with pain signals transmitted by smaller-diameter fibers, thus reducing the perception of pain. While helpful, it is not directly related to acupressure, which involves targeted pressure points.
Choice B rationale
Immersing oneself in warm water, or hydrotherapy, promotes muscle relaxation and reduces pain perception through buoyancy and heat transfer. The warmth increases blood flow and relaxes uterine muscles, providing comfort. This technique primarily acts on thermoreceptors and mechanoreceptors, facilitating systemic relaxation, distinct from the focused pressure of acupressure.
Choice C rationale
Placing tennis balls on the sacral area and leaning against them applies counterpressure, a technique effective for back labor. This external pressure can help alleviate pain by applying direct compression to the sacral nerves, which may be compressed by the fetal head. This method is a form of deep tissue manipulation, differing from the specific point stimulation of acupressure.
Choice D rationale
Acupressure involves applying pressure to specific anatomical points to alleviate pain and discomfort. Recognizing signals (e.g., contractions), responding (applying pressure), and relaxing (allowing the body's natural pain modulation) are key principles. This targets endogenous opioid release and influences neural pathways, promoting pain relief and often a sense of calm.
Correct Answer is D
Explanation
Choice A rationale
Multiple gestation, such as twins or triplets, typically results in elevated maternal serum alpha-fetoprotein (MSAFP) levels because there are multiple fetuses producing AFP. AFP is a protein produced by the fetal liver and yolk sac.
Choice B rationale
Neural tube defects, such as spina bifida or anencephaly, are associated with *elevated* levels of MSAFP due to the open defect allowing leakage of AFP into the amniotic fluid and then into the maternal circulation.
Choice C rationale
Intrauterine growth restriction (IUGR) can sometimes be associated with either normal or slightly elevated MSAFP levels, depending on the underlying cause, but it is not typically linked to *low* levels.
Choice D rationale
Low levels of maternal serum alpha-fetoprotein are associated with an increased risk of Down syndrome (Trisomy 21). This is thought to be due to altered placental function or fetal production of AFP in these pregnancies.
