A nurse is caring for a 26-year-old female client who is at 14 weeks of gestation in the antepartum clinic.
Select the 3 findings that are unexpected.
Weight loss
Breast tenderness
Heart rate
Vomiting
Nasal congestion
Respiratory rate
Correct Answer : A,C,D
Choice A rationale: Weight loss
Weight loss during pregnancy, especially in the second trimester, is unexpected unless there is a medical condition such as hyperemesis gravidarum or other nutritional deficiencies. While mild weight fluctuations can occur, a consistent loss of weight rather than gradual gain suggests inadequate caloric intake due to persistent vomiting and dehydration.
Choice B rationale: Breast tenderness
Breast tenderness is a common and expected physiological change during pregnancy due to hormonal fluctuations, particularly increased estrogen and progesterone levels. It is not considered abnormal or unexpected at this stage of pregnancy.
Choice C rationale: Heart rate
A heart rate of 116/min is unexpected, as it is above the normal range for adults (typically 60–100/min). Pregnancy can cause a mild increase in heart rate, but tachycardia above 110/min may indicate dehydration, anemia, or electrolyte imbalance, all of which can stem from excessive vomiting and fluid loss.
Choice D rationale: Vomiting
While occasional nausea and vomiting (morning sickness) can be expected in early pregnancy, persistent vomiting up to eight times daily and symptoms of dehydration (dry mucosa, poor skin turgor, positive ketones in urine) raise concern for hyperemesis gravidarum, a more severe form of pregnancy-related nausea and vomiting.
Choice E rationale: Nasal congestion
Nasal congestion is common during pregnancy due to increased blood volume and vascular changes affecting the nasal mucosa. It is not unexpected and does not indicate a complication.
Choice F rationale: Respiratory rate
A respiratory rate of 20/min falls within the normal range for adults (typically 12–20/min), making it an expected finding.

Correct Answer is C
Explanation
Choice A rationale
Placenta previa is a condition where the placenta partially or totally covers the cervix. While it poses risks for hemorrhage during labor and delivery, it does not directly increase the risk of postpartum infection. The primary risks associated with placenta previa are related to bleeding, not infection.
Choice B rationale
Meconium aspiration occurs when a fetus inhales meconium-stained amniotic fluid. This primarily affects the newborn's respiratory system and does not directly increase the postpartum client's risk of infection. The complications of meconium aspiration are focused on the neonate.
Choice C rationale
A midline episiotomy is a surgical incision made in the perineum during childbirth to enlarge the vaginal opening. This incision creates a break in the skin and mucous membranes, providing a potential portal of entry for bacteria. Therefore, a midline episiotomy places the postpartum client at an increased risk for local infection at the incision site.
Choice D rationale
Gestational hypertension is high blood pressure that develops during pregnancy and typically resolves after delivery. While it poses risks to both the mother and the fetus, it does not directly increase the postpartum client's risk of infection. The primary concerns with gestational hypertension are related to blood pressure control and potential end-organ damage.
Correct Answer is D
Explanation
Choice A rationale
Fetal hypoxemia, a deficiency in oxygen reaching the fetal tissues, typically manifests as late decelerations in the fetal heart rate tracing, which reflect uteroplacental insufficiency. While severe hypoxemia can lead to various FHR patterns, variable decelerations are more directly associated with mechanical factors affecting the umbilical cord.
Choice B rationale
Altered fetal cerebral blood flow can be a consequence of various factors, including hypoxemia and cord compression, and can influence the fetal heart rate. However, variable decelerations are specifically caused by events that directly impede blood flow through the umbilical vessels rather than a generalized alteration in cerebral circulation.
Choice C rationale
Uteroplacental insufficiency, a condition where the placenta is unable to deliver an adequate supply of oxygen and nutrients to the fetus, typically results in late decelerations, indicating fetal distress due to chronic hypoxia. Variable decelerations, in contrast, have a more abrupt onset and recovery, reflecting acute changes in umbilical cord blood flow.
Choice D rationale
Umbilical cord compression occurs when the umbilical cord, which carries oxygen and nutrients to the fetus, is squeezed or constricted. This compression leads to a transient decrease in fetal blood flow and oxygenation, resulting in a rapid drop and subsequent return of the fetal heart rate, which is characteristic of variable decelerations. The shape, timing, and abrupt nature of variable decelerations directly correlate with the intermittent pressure on the umbilical cord.
