A nurse is providing discharge teaching to a new guardian about car seat safety.
Which of the following statements by the guardian indicates an understanding of the teaching?
I should place the harness snugly in a slot above my baby's shoulders.
I should position the retainer clip at the top of my baby's abdomen.
I should position my baby's car seat at a 45-degree angle in the car.
I should place the car seat rear-facing until my baby is 12 months old.
The Correct Answer is C
Choice A rationale
The car seat harness straps should be positioned at or slightly below the baby's shoulders when the car seat is installed rear-facing. Positioning the straps above the shoulders could allow the baby to slide up and out of the harness in a crash due to the forces involved, compromising the restraint system's effectiveness and increasing injury risk.
Choice B rationale
The retainer clip, also called the chest clip, must be positioned at the level of the armpits across the center of the chest or sternum, not the abdomen. This critical placement ensures that the harness straps are kept correctly positioned over the baby's shoulders, preventing the straps from slipping off during a collision and maintaining optimal force distribution across the torso.
Choice C rationale
A 45-degree recline angle for a rear-facing car seat is generally recommended to prevent the infant's head from falling forward, which can compromise the airway, particularly in newborns or infants with poor head control. This specific angle is crucial for maintaining a safe and open airway and is often achieved using built-in level indicators on the car seat base.
Choice D rationale
Current safety recommendations advise keeping a child in a rear-facing car seat as long as possible, typically until they reach the maximum weight or height limit allowed by the car seat manufacturer, which often extends well beyond 12 months of age, frequently up to 2 to 4 years of age, for maximum spinal protection.

Related Questions
Correct Answer is C
Explanation
Choice A rationale
Misoprostol is a prostaglandin analog used to prevent or treat postpartum hemorrhage by inducing uterine contractions, but it is not the primary intervention for preeclampsia without severe features, which focuses on blood pressure control and seizure prophylaxis.
Choice B rationale
Administering an IV bolus of lactated Ringer's is generally contraindicated in preeclampsia because it can increase the risk of pulmonary edema due to generalized fluid retention and increased capillary permeability characteristic of the disorder. Fluid management should be conservative.
Choice C rationale
Clonus, which is the presence of rhythmic, involuntary muscle contractions, is a sign of hyperreflexia and central nervous system irritability. It indicates worsening preeclampsia and the potential progression to eclampsia (seizures), necessitating close neurological assessment for timely intervention.
Choice D rationale
Restricting daily oral fluid intake can lead to dehydration and is not a standard or necessary practice for preeclampsia management without severe features, unless there is evidence of pulmonary edema or acute kidney injury. The focus is on careful fluid balance, not routine restriction.
Correct Answer is ["A","C","E"]
Explanation
Choice A rationale
Oxytocin use for labor induction or augmentation is a significant risk factor for uterine atony, the most common cause of postpartum hemorrhage (PPH). Prolonged or high-dose exposure can lead to receptor downregulation or overstimulation, resulting in a fatigued or poorly contracting uterus, which fails to clamp down on the blood vessels at the placental site after delivery.
Choice B rationale
A history of Human Papillomavirus (HPV), a sexually transmitted infection, is not recognized as an independent risk factor for increasing the likelihood of postpartum hemorrhage. The physiological mechanisms leading to PPH are primarily related to uterine function, trauma, or coagulation disorders, which HPV infection does not directly influence.
Choice C rationale
A history of uterine atony in a previous pregnancy significantly increases the risk for recurrence in subsequent deliveries because it suggests an underlying predisposition for the myometrium to fail its contractile function. Uterine atony prevents the spiral arteries from being compressed, leading to excessive blood loss, which defines postpartum hemorrhage.
Choice D rationale
The average newborn weight in Western populations is approximately 3.4 kg (7.5 lb), with a normal range generally considered between 2.5 kg and 4.0 kg. A newborn weight of 2.948 kg (6 lb 8 oz) is within the normal range and does not constitute a risk factor for PPH, unlike macrosomia (birth weight > 4000 g or 8 lb 13 oz) which overdistends the uterus.
Choice E rationale
Vacuum-assisted delivery, a form of operative vaginal delivery, increases the risk of PPH primarily due to associated genital tract trauma (e.g., cervical, vaginal, or perineal lacerations) and potentially compounding the risk of uterine atony from prolonged labor or necessary manual maneuvers. Trauma contributes to bleeding that is non-uterine in origin.
