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 D
Explanation
Choice A rationale
IUD replacement depends on the type. For instance, hormonal IUDs typically last 3-5 years, and copper IUDs can last up to 10 years. Annual replacement is unnecessary.
Choice B rationale
Spermicide use is unnecessary with an IUD as its primary function is to prevent fertilization. This statement reflects a lack of understanding of IUD mechanisms.
Choice C rationale
Periods may become lighter or irregular with hormonal IUDs, but they rarely stop completely. Copper IUDs may actually increase menstrual flow in some cases.
Choice D rationale
Checking for the string ensures proper IUD positioning and functionality. This monthly practice helps detect dislodgement or expulsion, which can compromise contraceptive effectiveness.
Correct Answer is B
Explanation
Choice A rationale
Nevus flammeus is a capillary malformation, presenting as a flat, purple-red birthmark that does not cause swelling or cross suture lines, distinguishing it from caput succedaneum.
Choice B rationale
Caput succedaneum involves swelling of the scalp caused by pressure during delivery, often crossing suture lines due to subcutaneous fluid accumulation, a hallmark distinguishing it from other neonatal head conditions.
Choice C rationale
Cephalohematoma is a subperiosteal hemorrhage limited by suture lines, making it distinct from caput succedaneum, which crosses suture lines and involves diffuse subcutaneous swelling.
Choice D rationale
Erythema toxicum is a benign, blotchy skin condition in neonates that does not affect the scalp or cause swelling, further distinguishing it from conditions related to traumatic delivery.
