The nurse is going to use a bulb syringe to clear mucus from a newborn's nose and mouth. What is the nurse's first action?
Place the tip in the nose and squeeze the bulb gently.
Insert the tip into the back of the mouth to reach mucus.
Depress the bulb before inserting the syringe tip into the mouth.
Suction secretions from the nose before the mouth.
Weight
The Correct Answer is C
A. Place the tip in the nose and squeeze the bulb gently: Squeezing the bulb before insertion can create a vacuum that draws mucus into the syringe, but the first step is to depress the bulb to remove air and allow proper suctioning once the tip is in place.
B. Insert the tip into the back of the mouth to reach mucus: Inserting the tip too far into the mouth can trigger gagging or injury. Suctioning should begin with the mouth only after the bulb has been properly prepared and inserted safely.
C. Depress the bulb before inserting the syringe tip into the mouth: Depressing the bulb expels air, creating suction when the tip is released inside the mouth. Clearing the mouth first is important to prevent aspiration, and this step ensures effective and safe suctioning.
D. Suction secretions from the nose before the mouth: Suctioning the nose before the mouth can cause the infant to aspirate mucus from the oropharynx. The mouth should be cleared first to reduce the risk of airway compromise.

Correct Answer is D
Explanation
A. Focus on the family unit and its members: Focusing on the family unit occurs during the taking-hold phase, when the mother begins to assume responsibility for newborn care and actively participates in family adjustment.
B. Eagerness to learn newborn care skills: Eagerness to learn and practice care skills is characteristic of the taking-hold phase, which typically follows the initial dependent, or taking-in, phase.
C. Lack of appetite: While appetite may be temporarily decreased due to fatigue or discomfort, it is not a defining feature of the taking-in phase of maternal postpartum adjustment.
D. Expressions of excitement: During the dependent, taking-in phase, which occurs in the first 24–48 hours postpartum, the mother is focused on her own recovery and may express excitement, talk about the birth experience, and show dependence on others for comfort and basic needs.
Correct Answer is D
Explanation
A. Heat increases the flow of oxygen to the extremities: While warmth may improve peripheral circulation, the primary reason for using an incubator is not to enhance oxygen delivery. Oxygenation depends on lung function and cardiovascular status, not just heat.
B. The infant has a small body surface-to-weight ratio: Preterm infants actually have a large body surface area relative to weight, which increases heat loss. While surface area contributes to thermal regulation challenges, this is part of the broader issue of immature thermoregulation.
C. Heat within the incubator facilitates drainage of mucus: Maintaining warmth does not directly affect mucus clearance. Mucus drainage depends on suctioning, airway management, and hydration rather than incubator temperature.
D. The infant's temperature control mechanism is immature: Preterm infants have underdeveloped hypothalamic thermoregulation and limited brown fat stores, making it difficult to maintain body temperature. An incubator provides a controlled thermal environment to prevent hypothermia and support metabolic stability.
