A nurse is reinforcing teaching with a client who is undergoing amniotic fluid assessment for the lecithin/sphingomyelin ratio.Which of the following client statements indicates an understanding of the teaching?

An ectopic pregnancy is most likely due to the combination of symptoms: dizziness, pale skin, cool extremities, low blood pressure (86/48 mm Hg), and high heart rate (120/min). The soft and non-tender abdomen with no palpable contractions also suggests an ectopic pregnancy rather than other conditions. The low hematocrit (25%) and hemoglobin (9 g/dL) indicate significant blood loss, a hallmark of ectopic pregnancy.

Administer methotrexate is important to stop the growth of the embryo in an ectopic pregnancy. Insert a large-bore peripheral IV catheter to manage blood loss and prepare for potential surgery.

Monitoring beta human chorionic gonadotropin (hCG) levels is crucial to confirm the diagnosis and monitor treatment response. Platelet count should be monitored due to the risk of bleeding associated with an ectopic pregnancy.

Placenta previa usually presents with painless vaginal bleeding, which is absent in this case. Chorioamnionitis is typically associated with infection signs like fever, uterine tenderness, and elevated white blood cell count, not primarily dizziness and low blood pressure. Cervical insufficiency usually presents with painless cervical dilation, leading to preterm birth, not the acute signs seen here. Vaginal bleeding is a symptom, not a diagnosis, and this client reports no vaginal bleeding.

Choice A rationale

Positioning the newborn's car seat at a 45° angle helps to maintain an open airway and reduces the risk of the baby's head falling forward, which can obstruct breathing.

Choice B rationale

Placing the car seat in a forward-facing position is incorrect for a newborn. Newborns and infants should always be placed in a rear-facing car seat to protect their head, neck, and spine in the event of a crash.

Choice C rationale

Placing a rolled blanket behind the newborn's neck is not recommended as it can alter the position of the head and neck, potentially compromising the airway. Proper positioning is crucial to ensure safety and comfort.

Choice D rationale

The retainer clip should be positioned at the level of the newborn's armpits, not the umbilicus. Proper placement of the retainer clip ensures that the harness is secure and reduces the risk of injury in a collision.
