ATI Maternal Newborn

Correct Answer: C

Rationale: Erythromycin eye ointment is the medication of choice for preventing ophthalmia neonatorum, an eye infection in newborns caused by exposure to gonorrhea or chlamydia during birth. Erythromycin helps prevent the transmission of these bacteria from the mother to the baby during delivery, protecting the newborn's eyes from potential infection. Ofloxacin, Nystatin, and Ceftriaxone are not indicated for preventing ophthalmia neonatorum. Ofloxacin is a fluoroquinolone antibiotic used for treating eye infections in adults, Nystatin is an antifungal medication used for fungal infections, and Ceftriaxone is a cephalosporin antibiotic used for various bacterial infections, but not for preventing ophthalmia neonatorum.

Correct Answer: A

Rationale: A bluish-brown marking across the lower back is more commonly seen in newborns with dark skin. These markings are known as Mongolian spots and are benign. They are not related to hyperbilirubinemia, forceps marks, or trauma during delivery. Choice B is incorrect because hyperbilirubinemia presents as jaundice, not as a bluish-brown marking. Choice C is incorrect because forceps marks would have a different appearance and location. Choice D is incorrect as Mongolian spots are not related to prolonged birth or trauma during delivery.

Correct Answer: A

Rationale: In a newborn with respiratory distress syndrome who has received synthetic surfactant, monitoring oxygen saturation is crucial to evaluate the effectiveness of the treatment. Oxygen saturation levels provide valuable information about the newborn's respiratory status and the adequacy of gas exchange. Changes in oxygen saturation can indicate improvements or deterioration in the newborn's condition following the administration of synthetic surfactant. Monitoring oxygen saturation helps the nurse assess the newborn's response to treatment and make timely interventions if needed. Body temperature, serum bilirubin, and heart rate are important parameters to monitor in newborns for other conditions but are not specific indicators of the effectiveness of synthetic surfactant in treating respiratory distress syndrome.

Correct Answer: A

Rationale: During pregnancy, gradual lordosis is a common adaptation to the growing fetus. Lordosis refers to an increased lumbar curve in the spine, which helps to shift the center of gravity forward, supporting the enlarging uterus. This change is necessary to maintain balance and reduce strain on the back muscles as the pregnancy progresses. Increased abdominal muscle tone, posterior neck flexion, and decreased mobility of pelvic joints are not typical physiological changes during pregnancy. Increased abdominal muscle tone is not expected as the abdominal muscles tend to stretch and separate to accommodate the growing fetus. Posterior neck flexion is not a common finding and decreased mobility of pelvic joints is not an expected change and can cause discomfort.

Correct Answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.
