A nurse is collecting data from a client who has been diagnosed with trichomonas.
Which of the following findings should the nurse identify as a manifestation of trichomonas infection?

Choice A rationale

At 6 weeks of gestation, the embryonic stage involves significant cephalocaudal development. During this period, the optic vesicles are forming, and apical eye pigment becomes visible as the rudimentary eyes begin to develop. This is a critical milestone in sensory organ formation. While the embryo is only about 0.5 inches long, the foundation for the visual system is being laid through complex cellular differentiation and migration of neuroectodermal cells that will eventually form the retina and other ocular structures.

Choice B rationale

Meconium, which consists of swallowed amniotic fluid, bile, and intestinal secretions, does not begin to accumulate in the fetal intestines until much later in pregnancy, typically around the second trimester. At 6 weeks, the midgut is just beginning to form and is actually herniating into the umbilical cord because the abdominal cavity is too small to contain it. The digestive tract is far too primitive at this stage to produce or contain meconium, making this statement inaccurate for early embryonic development.

Choice C rationale

Although the genetic sex of the embryo is determined at conception by the chromosomes, the physical biological sex is not identifiable at 6 weeks of gestation. The gonads remain undifferentiated and visually identical in both males and females until approximately the 7th or 8th week of development. External genitalia do not become clearly distinguishable via ultrasound or physical examination until roughly 12 to 14 weeks. Therefore, a nurse cannot identify the biological sex based on morphological features at this early stage.

Choice D rationale

At 6 weeks of gestation, the heart is still in a primitive state and has not yet completed its transition into a four-chambered structure. The heart begins as a simple tube and starts beating around week 4. By week 6, it is undergoing a process called looping and septation to eventually form the atria and ventricles. However, the completion of the four-chambered heart and the development of distinct valves and septa typically occur by the end of the 8th week of gestation.

Choice A rationale

Maternal health conditions, including autoimmune and endocrine disorders, are significant risk factors for spontaneous abortion. Celiac disease, an immune-mediated enteropathy triggered by gluten, can lead to malabsorption of essential nutrients like folic acid and vitamin B12 if not strictly managed. Nutritional deficiencies and the systemic inflammatory response associated with untreated celiac disease can impair placental development and function, thereby increasing the statistical risk of early pregnancy loss or intrauterine growth restriction.

Choice B rationale

Maternal age is a factor in pregnancy loss, but the risk significantly increases primarily after the age of 35 due to a higher incidence of chromosomal abnormalities and declining oocyte quality. A 32-year-old woman is not considered to be at an advanced maternal age and generally has a baseline risk for spontaneous abortion similar to younger cohorts. Therefore, stating that being 32 years old is a specific risk factor is clinically inaccurate in this context.

Choice C rationale

Employment in food service is generally not considered a direct risk factor for spontaneous abortion unless it involves specific, severe environmental hazards or heavy physical lifting beyond safety guidelines. Most occupational risks related to pregnancy loss involve exposure to ionizing radiation, certain anesthetic gases, or specific industrial chemicals. General service work, while physically demanding, does not carry the same physiological risk profile as underlying medical conditions or significant environmental toxins known to cause fetal demise.

Choice D rationale

A history of fetal demise at 30 weeks is classified as a stillbirth or late-term pregnancy loss, not a spontaneous abortion. Spontaneous abortion, or miscarriage, is defined as the loss of a pregnancy before 20 weeks of gestation. While a history of late-term loss increases the risk for complications in future pregnancies, it is not a direct risk factor for the specific category of spontaneous abortion. The causes of late-term demise often differ from early losses.
