A nurse is providing vehicle safety education to the parents of a premature newborn.
Which of the following statements should the nurse include in the teaching?
"Your newborn will need to have a car seat test prior to discharge.”.
"Position the retainer clip at the level of your newborn's abdomen.”.
"Place your newborn in a front-facing car seat in the back seat of the vehicle.”.
"You should secure your newborn's car seat at a 60-degree angle.”.
The Correct Answer is A
Choice A rationale
Premature newborns have immature respiratory and neurological systems, making them vulnerable to respiratory compromise and apnea in a car seat. A car seat test prior to discharge assesses their ability to maintain adequate oxygenation and heart rate while positioned in the car seat for a prolonged period, ensuring safety.
Choice B rationale
The retainer clip should be positioned at the level of the newborn's armpits, not the abdomen. Proper placement at the armpit level ensures that the harness straps are snug over the shoulders and chest, effectively restraining the infant and preventing ejection in the event of a collision, optimizing crash protection.
Choice C rationale
Newborns, especially premature ones, must always be placed in a rear-facing car seat in the back seat of the vehicle. Rear-facing provides optimal support for the newborn's fragile head, neck, and spine, distributing crash forces over the entire back and significantly reducing the risk of severe injuries in a collision.
Choice D rationale
The recommended angle for a rear-facing car seat is typically between 30 to 45 degrees, depending on the specific car seat model, not 60 degrees. This recline angle is crucial to prevent the newborn's head from falling forward and compromising their airway, which is particularly critical for a premature infant with underdeveloped neck control. .

Correct Answer is C
Explanation
Choice A rationale
Administering a rubella immunization during pregnancy is contraindicated because the rubella vaccine is a live attenuated virus vaccine. There is a theoretical risk of viral transmission to the fetus, which could lead to congenital rubella syndrome. Vaccination should occur postpartum to protect future pregnancies.
Choice B rationale
Breastfeeding is not contraindicated after receiving the rubella vaccine. Although rubella vaccine virus can be excreted in breast milk, it generally does not cause clinical illness in the infant and passive transfer of antibodies may provide some protection to the infant.
Choice C rationale
A rubella titer of 1: indicates a low level of rubella antibodies, meaning the client is susceptible to rubella infection. A titer of less than 1: or 1: is generally considered non-immune, requiring vaccination to prevent congenital rubella syndrome in future pregnancies.
Choice D rationale
Repeating a rubella titer in the third trimester is not a standard practice for assessing susceptibility. Once susceptibility is determined, the primary intervention is postpartum vaccination. The initial titer result accurately reflects immune status and further testing during pregnancy is unnecessary.
Correct Answer is {"A":{"answers":"B"},"B":{"answers":"A,B"},"C":{"answers":"A"},"D":{"answers":"A,B"}}
Explanation
Abruptio Placentae: Typically does not cause increased contraction frequency; contractions may be normal or decreased due to uterine irritation or pain.
Uterine Tachysystole: Characterized by more than 5 contractions in 10 minutes averaged over 30 minutes, indicating excessive contraction frequency, which can reduce uteroplacental perfusion.
Uterine Tone
Abruptio Placentae: The uterus often becomes firm, rigid, and tender due to bleeding and inflammation caused by premature placental separation, increasing baseline uterine tone.
Uterine Tachysystole: Uterine tone is elevated because contractions are prolonged and close together, causing the uterus to remain tense with insufficient relaxation.
Pain Report
Abruptio Placentae: Patients usually report sharp, severe abdominal or back pain due to the sudden placental detachment and uterine irritation.
Uterine Tachysystole: Pain may be present but is typically related to frequent contractions rather than sharp, localized pain.
FHR Pattern
Abruptio Placentae: Commonly causes fetal heart rate abnormalities like late decelerations, bradycardia, or absent variability due to fetal hypoxia from compromised placental perfusion.
Uterine Tachysystole: Can cause decreased fetal heart rate variability and late decelerations because frequent contractions reduce oxygen delivery during inadequate relaxation.
