A nurse is assessing a newborn following a circumcision 48 hr ago.
The nurse should identify that yellow exudate covering the newborn's glans penis indicates which of the following?

Choice A rationale

While weight gain is crucial during pregnancy, a blanket statement of 2 pounds per week is not universally appropriate. The recommended rate of weight gain varies based on the client's pre-pregnancy BMI and the trimester. Excessive or insufficient weight gain can lead to adverse maternal and fetal outcomes, including macrosomia or intrauterine growth restriction, highlighting the need for individualized nutritional guidance rather than a fixed weekly gain.

Choice B rationale

Dieting during pregnancy, especially restrictive calorie intake, can significantly compromise the nutrient supply to the developing fetus. Fetal growth and organogenesis are highly dependent on adequate maternal nutritional stores and daily nutrient intake. Inadequate nutrition can lead to low birth weight, premature birth, and long-term health complications for the infant, emphasizing the dangers of unguided dietary restrictions.

Choice C rationale

A dietitian possesses specialized knowledge in medical nutrition therapy and can provide personalized recommendations based on the adolescent's specific nutritional needs, gestational age, and pre-pregnancy weight. This collaborative approach ensures optimal maternal and fetal health by addressing any deficiencies, managing appropriate weight gain, and promoting healthy eating habits throughout the pregnancy, which is crucial for adolescent development and pregnancy outcomes.

Choice D rationale

The caloric needs of a pregnant adolescent increase in the second and third trimesters, but a fixed additional 700 calories per day may not be accurate for all individuals. Caloric requirements are dynamic and depend on pre-pregnancy weight, activity level, and the specific stage of gestation. Overestimation can lead to excessive weight gain, while underestimation can result in inadequate fetal growth, necessitating individualized assessment.

The nurse should identify that the client is at the greatest risk for preterm birth due to fetal fibronectin.

Rationale for correct answers:
Fetal fibronectin (fFN) is a glycoprotein found at the maternal-fetal interface, serving as a “biological glue” between the chorion and decidua. Normally, fFN is not detectable in cervicovaginal secretions between 22 and 34 weeks gestation. A level greater than 0.05 mcg/mL, such as this client’s 0.09 mcg/mL, signals disruption of the fetal membranes and an increased risk of preterm birth. It has a high negative predictive value, so a positive result strongly suggests premature labor risk, prompting interventions like tocolytics and corticosteroids to promote fetal lung maturity.

Rationale for incorrect Response 1 options:
Precipitous labor is rapid labor lasting under 3 hours from onset to delivery. Fetal fibronectin does not predict the speed of labor but the risk of preterm onset. This client’s labor is not precipitous based on exam and monitoring.

Chorioamnionitis is an intra-amniotic infection usually accompanied by maternal fever, uterine tenderness, and fetal tachycardia. Fetal fibronectin does not indicate infection.

Preeclampsia involves hypertension and proteinuria after 20 weeks and is unrelated to fetal fibronectin levels.

Rationale for incorrect Response 2 options:
Nitrazine and ferning tests assess membrane rupture. Both are negative here, indicating intact membranes, which does not exclude preterm labor but means premature rupture of membranes (PPROM) is unlikely.

Blood pressure measurements evaluate maternal hemodynamics, not risk of preterm birth.

Take-home points:

• Elevated fetal fibronectin (>0.05 mcg/mL) between 22-34 weeks indicates increased risk for preterm birth.
• Negative nitrazine and ferning tests suggest membranes are intact, helping differentiate preterm labor from PPROM.
• Preterm labor risk should be differentiated from precipitous labor, infection (chorioamnionitis), and hypertensive disorders like preeclampsia.
• Early identification of preterm labor risk allows timely administration of tocolytics and corticosteroids to improve neonatal outcomes.
