At a prenatal visit at 36 weeks' gestation, a client complains of discomfort with irregularly occurring contractions (Braxton Hicks contractions). The nurse instructs the client to:

The condition that poses the greatest risk to the newborn is meconium aspiration syndrome due to amniotic fluid.

Rationale for correct answers

Meconium aspiration syndrome (MAS) occurs when a newborn inhales meconium-stained amniotic fluid, leading to airway obstruction, chemical pneumonitis, and surfactant dysfunction. The presence of dark brown-greenish amniotic fluid, along with mild respiratory distress (nasal flaring, increased respiratory rate of 60/min), raises concern for MAS. Close monitoring for worsening respiratory symptoms is essential.

Amniotic fluid contamination with meconium increases the risk of lung inflammation and infection. The newborn’s vigorous condition suggests mild aspiration, but continuous observation is needed.

Rationale for incorrect Response 1 options

• Jaundice: While term newborns may develop physiological jaundice, there are no indications of hyperbilirubinemia or hemolysis in this case.
• Hypoglycemia: No jitteriness or poor feeding, and birth weight is within normal range; hypoglycemia more commonly affects preterm or low birth weight infants.
• Cold stress: The newborn is under a radiant warmer, and temperature is within normal range (36.5°C).

Rationale for incorrect Response 2 options

• Birth weight: No signs of growth restriction or macrosomia-associated complications.
• Acrocyanosis: Normal in newborns due to immature circulation, not an indicator of respiratory compromise.
• Apgar scores: Strong Apgar scores (8 and 9) suggest good adaptation to extrauterine life.

Choice A rationale

Gonorrhea typically presents with a purulent, often thick, yellow discharge. While it can have a foul odor, the description of frothy and bubbly is less characteristic of gonorrhea. Diagnosis usually involves a cervical culture or nucleic acid amplification testing (NAAT).

Choice B rationale

Trichomoniasis, caused by the protozoan *Trichomonas vaginalis*, is characteristically associated with a large amount of yellow-green or gray, frothy, and bubbly vaginal discharge with a distinct, often foul or fishy odor. Microscopic examination of the discharge reveals the motile trichomonads for definitive diagnosis.

Choice C rationale

Chlamydia often presents with a thin or mucopurulent discharge, which may be yellowish, but it is not typically described as frothy or bubbly. Many women with chlamydia are asymptomatic. Diagnosis is usually made through NAAT of cervical or urine samples.

Choice D rationale

Syphilis in its primary stage presents with a painless chancre. Secondary syphilis can involve a generalized rash and flu-like symptoms. Vaginal discharge is not a primary characteristic of either the primary or secondary stages of syphilis. Diagnosis involves serological testing.
