Choice A rationale: Flat and open anterior and posterior fontanels are normal findings in a newborn. These soft spots allow for brain growth and accommodate molding during birth. The anterior fontanel typically measures 1–4 cm and closes by 18 months, while the posterior fontanel is smaller and closes by 2 months. Their presence and flatness indicate normal intracranial pressure and hydration status, requiring no follow-up unless bulging or sunken.

Choice B rationale: A firm, edematous area on the scalp that does not cross suture lines suggests a cephalohematoma, which is a subperiosteal hemorrhage. This condition is associated with vacuum-assisted deliveries and increases the risk for hyperbilirubinemia due to breakdown of accumulated red blood cells. Cephalohematomas typically resolve spontaneously but require monitoring for jaundice and anemia. Follow-up is essential to assess bilirubin levels and ensure no complications such as infection or calcification.

Choice C rationale: Fine crackles in the lower lung fields may indicate retained fetal lung fluid or transient tachypnea of the newborn (TTN), especially in late preterm infants. While crackles can be benign in the first hours of life, persistence beyond 24 hours warrants evaluation for respiratory distress or infection. Pulmonary auscultation should be repeated, and oxygenation monitored. Crackles may also signal aspiration or pneumonia, necessitating follow-up to rule out pathology.

Choice D rationale: Acrocyanosis, or bluish discoloration of the hands and feet, is common in the first 24–48 hours of life due to immature peripheral circulation. However, persistence beyond this period may indicate poor perfusion or underlying cardiac issues. In this case, the newborn is on day 3, and continued acrocyanosis requires follow-up to assess for hypoxemia, congenital heart defects, or sepsis. Pulse oximetry and cardiovascular evaluation are warranted.

Choice E rationale: Facial bruising is often associated with birth trauma, especially in vacuum-assisted deliveries. While bruising itself may resolve without intervention, it contributes to increased bilirubin production due to hemolysis of extravasated red blood cells. In a newborn already undergoing phototherapy for hyperbilirubinemia, additional bruising increases the risk for worsening jaundice. Follow-up is necessary to monitor bilirubin levels and ensure adequate phototherapy adherence.

Choice F rationale: Moist, pink, and intact oral mucosa indicates good hydration, oxygenation, and absence of mucosal lesions or infection. This finding reflects normal tissue perfusion and integrity. No follow-up is needed unless signs of dehydration, cyanosis, or oral thrush develop. It confirms that feeding is adequate and systemic circulation is intact.

Choice G rationale: A moist umbilical cord with three vessels—two arteries and one vein—is a normal anatomical finding. The presence of three vessels confirms normal fetal circulation and renal development. Moistness indicates appropriate healing without signs of infection. No follow-up is required unless there is foul odor, purulent discharge, or delayed cord separation.

Choice H rationale: Vernix caseosa is a protective, waxy substance found in skin folds of newborns. It provides antimicrobial properties and prevents skin desiccation. Its presence is normal, especially in preterm or late preterm infants. Vernix is gradually absorbed or removed during bathing. No follow-up is needed unless there are signs of skin breakdown or infection.

Choice A rationale

Transcutaneous electrical nerve stimulation (TENS) operates on the Gate Control Theory of Pain, where non-painful electrical stimuli are applied, attempting to block the transmission of pain signals. The intensity must be manually increased by the client during a contraction to override the escalating pain impulse and achieve maximum analgesic effect when the pain is most intense, providing the best pain modulation.

Choice B rationale

TENS is primarily used for the low back pain and abdominal pain experienced during the active phase of the first stage of labor (cervical dilation), providing a distraction and non-pharmacological pain relief option. It is less effective during the second stage (pushing) and is not typically indicated for the third stage of labor (placental expulsion), which has different pain mechanisms.

Choice C rationale

TENS works by stimulating large sensory nerve fibers to modulate or decrease the perception of pain (pain modulation), offering a sense of control and relief, but it does not eliminate the pain entirely, particularly the intense visceral pain of uterine contractions. It is a non-invasive pain coping mechanism, not an anesthetic agent that would abolish pain sensation.

Choice D rationale

Gestational diabetes mellitus (GDM) is a maternal metabolic condition and is not a contraindication for the use of TENS during labor. The primary contraindications for TENS include the use of a cardiac pacemaker, application over the heart or head, or in the presence of fetal electronic monitoring electrodes that could conduct the current, none of which are related to GDM.
