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 C
Explanation
Choice A rationale
Yearly Pap tests until 70 years of age are not universally recommended. Current guidelines suggest screening every three years for most individuals, dependent on specific health factors.
Choice B rationale
Removal of ovaries does not eliminate the need for Pap tests. Cervical tissue, the focus of the test, remains unless a hysterectomy with cervix removal is performed.
Choice C rationale
Avoiding intercourse for 24 hours minimizes contamination of cervical cells with external materials, ensuring accurate Pap test results. It is an important preparatory guideline.
Choice D rationale
Pap tests detect cervical dysplasia or malignancy rather than viral infections. Secondary HPV-related cellular changes may be identified, but it is not a primary diagnostic tool for viruses.
Correct Answer is A
Explanation
Choice A rationale
A respiratory rate of 11/min is below the normal adult range of 12–20/min and indicates respiratory depression, a potential adverse effect of magnesium sulfate requiring immediate intervention.
Choice B rationale
Deep tendon reflexes graded 2+ are within the normal range, indicating that magnesium sulfate has not caused neuromuscular suppression, which would present as absent or diminished reflexes.
Choice C rationale
A urine output of 30 mL/hr meets the minimum renal perfusion threshold, so it does not indicate magnesium toxicity or renal impairment, which would show decreased urine production.
Choice D rationale
Blood pressure of 100/62 mm Hg is low-normal and does not signify hypotension related to magnesium sulfate use. Vital signs within this range are not typically concerning in this context.
