A nurse is assessing a client who has placenta previa and is receiving fetal monitoring.Which of the following clinical findings should the nurse expect?
Variable decelerations.
Painless vaginal bleeding.
Rigid abdomen.
Uterine tachysystole.
The Correct Answer is B
Choice A rationale
Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause variable decelerations on fetal monitoring.
Choice B rationale
Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates or effaces.
Choice C rationale
A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in placenta previa.
Choice D rationale
Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use or other uterine stimulants.

Correct Answer is A
Explanation
Choice A rationale
Rear-facing car seats are safer for infants and toddlers because they provide better support for their head, neck, and spine in the event of a collision. The American Academy of Pediatrics recommends keeping children in rear-facing seats until they are at least 2 years old or until they reach the highest weight or height allowed by the manufacturer.
Choice B rationale
A four-point harness is not sufficient for securing a baby in a car seat. A five-point harness, which includes two shoulder straps, two hip straps, and one crotch strap, provides more secure and effective restraint for infants.
Choice C rationale
The shoulder harness should be positioned in the slots at or below the baby's shoulders, not above, to ensure proper fit and restraint. Placing the harness above the shoulders can result in improper restraint and increased risk of injury in an accident.
Choice D rationale
The correct angle for a rear-facing car seat is typically 45 degrees, not 30 degrees. A 45-degree angle ensures the baby's airway remains open, preventing the head from falling forward and potentially causing breathing difficulties.
Correct Answer is C
Explanation
Choice A rationale
Giving glucose water after feedings is not recommended for newborns undergoing phototherapy. Breastfeeding or formula feeding should be continued to provide adequate nutrition and hydration.
Choice B rationale
Instructing the client to avoid breastfeeding during treatment is not necessary. Breastfeeding should continue to promote bonding, provide nutrition, and help with the infant's hydration and bilirubin excretion.
Choice C rationale
Monitoring intake and output is crucial for a newborn receiving phototherapy to ensure proper hydration and assess the effectiveness of the treatment in lowering bilirubin levels.
Choice D rationale
Applying lotions and ointments throughout the treatment is not recommended, as they can interfere with the effectiveness of phototherapy. The skin should be clean and dry to maximize exposure to the phototherapy light.
