A nurse is teaching the parent of a newborn about car seat safety.
Which of the following statements should the nurse make?
"You should keep the car seat rear-facing until your baby is at least 2 years old.”.
"Position the retainer clip over the upper part of your baby's abdomen.”.
"You should place your baby in the car seat at a 90-degree angle.”.
"Place the shoulder harness straps in the slots an inch above your baby's shoulders.”.
The Correct Answer is A
Choice A rationale
Rear-facing car seats support a baby’s head and spine during sudden stops or collisions. Experts recommend maintaining this position until 2 years to reduce injury risk.
Choice B rationale
Positioning the retainer clip on the upper abdomen risks internal organ damage during a crash. Proper placement is across the chest at armpit level to safely restrain movement.
Choice C rationale
A 90-degree angle would force a newborn upright, compromising the airway. The recommended angle is 30–45 degrees to maintain an open airway and adequate breathing.
Choice D rationale
Harness straps should be positioned at or below the shoulders, not above, to prevent the baby from sliding upward, which increases the risk of ejection during an accident.

Correct Answer is B
Explanation
Choice A rationale: Low uterine tone with mild vaginal bleeding is more indicative of placenta previa rather than abruptio placenta. Placenta previa involves the placenta covering the cervix, leading to painless bleeding. Uterine tone remains soft as there is no detachment of the placenta from the uterine wall. Abruptio placenta, however, is characterized by uterine rigidity due to blood accumulation between the placenta and uterine wall.
Choice B rationale: Rigid uterine tone with dark vaginal bleeding is a hallmark of abruptio placenta. The rigidity arises from blood pooling behind the placenta, causing uterine muscle contraction. Dark vaginal bleeding occurs as the blood is often concealed and clotted before expulsion. This condition is a medical emergency due to the risk of maternal hemorrhage and fetal hypoxia. Prompt diagnosis and intervention are critical to prevent severe complications.
Choice C rationale: Soft uterine tone with painless vaginal bleeding is characteristic of placenta previa, not abruptio placenta. Placenta previa involves the placenta partially or completely covering the cervix, leading to painless bleeding as the placenta detaches from the lower uterine segment. The uterine tone remains soft because there is no significant blood accumulation or uterine muscle contraction, unlike in abruptio placenta.
Choice D rationale: Low uterine tone with absence of vaginal bleeding does not align with abruptio placenta. While concealed abruptio placenta can occur without visible bleeding, the uterine tone is typically rigid due to blood accumulation. Low uterine tone suggests a lack of uterine contraction or detachment, which is inconsistent with the pathophysiology of abruptio placenta. This finding may indicate other obstetric conditions rather than abruptio placenta.
Correct Answer is E
Explanation
Choice A rationale
No acute distress indicates the client's physiological stability. It reflects an absence of acute systemic responses like tachycardia or labored breathing, suggesting normal homeostasis during examination.
Choice B rationale
No cardiovascular murmurs or rubs imply normal valve function and an absence of pericardial inflammation. This finding indicates no pathological blood flow changes or cardiac friction sounds.
Choice C rationale
Clear bilateral breath sounds suggest open airways and proper ventilation, excluding lower respiratory tract issues like pneumonia. Normal respiratory examination confirms adequate pulmonary function.
Choice D rationale
Fundal height at 38 cm corresponds to late-third trimester pregnancy. It reflects uterine enlargement due to fetal growth, indicating gestational progression but unrelated to cervical discharge.
Choice E rationale
Purulent cervical discharge suggests an ongoing infection, likely bacterial cervicitis. It reflects leukocyte accumulation due to pathogenic invasion, requiring clinical intervention to prevent complications.
