Which behavior observed by the nurse represents a normal social or personal skill milestone for a 4-year-old child?

Choice A rationale

Eating three large meals is contraindicated because it increases gastric volume and pressure, which can exacerbate nausea and trigger vomiting during pregnancy. Physiological changes in the first trimester involve rising human chorionic gonadotropin levels that slow gastric emptying. Consuming larger quantities of food at once leads to excessive stomach distention, further delaying the transit of contents and increasing the likelihood of gastroesophageal reflux and morning sickness symptoms.

Choice B rationale

Consuming significant amounts of fluid during meals can lead to overdistention of the stomach and a feeling of excessive fullness, which often triggers the gag reflex in pregnant clients. It is scientifically more effective to separate liquid and solid intake to avoid overloading the digestive system. Keeping fluids between meals ensures hydration without increasing the gastric pressure that typically accompanies the simultaneous intake of solids and liquids, thereby reducing the frequency of emetic episodes.

Choice C rationale

Dry carbohydrates like crackers are effective because they help absorb excess gastric acid and stabilize blood glucose levels before the client changes position. In the morning, an empty stomach and low blood sugar can trigger the chemoreceptor trigger zone, leading to nausea. By consuming bland, dry starches before rising, the client prevents the sudden shift in gastric contents and metabolic state that occurs with movement, providing a buffer against pregnancy-induced emesis.

Choice D rationale

High-fat diets are difficult to digest and significantly delay gastric emptying time, which is already slowed by the hormone progesterone. Fatty foods relax the lower esophageal sphincter, allowing gastric acid to reflux and irritate the esophageal lining, which intensely worsens nausea. Promoting a diet high in simple carbohydrates and proteins is scientifically preferred, as these are processed more efficiently by the gastrointestinal tract and do not contribute to the greasy residue that triggers nausea.

Choice A rationale

The fallopian tubes are the most common site for ectopic pregnancies, accounting for approximately 95 percent of all cases. Specifically, the ampulla is the most frequent location within the tube. This occurs when a fertilized ovum is delayed or prevented from migrating to the uterine cavity, often due to scarring from pelvic inflammatory disease or previous surgery. Because the tubes are not designed to support a growing fetus, rupture can lead to life-threatening internal hemorrhage and shock.

Choice B rationale

An abdominal ectopic pregnancy is a rare form where the embryo implants within the peritoneal cavity. This can occur primarily on the omentum or bowel, or secondarily after a tubal rupture. Although these pregnancies can occasionally progress further than tubal gestations, they represent a very small percentage of ectopic cases. They are associated with high maternal risk due to the potential for placental attachment to vital organs and major blood vessels, necessitating complex surgical management and monitoring.

Choice C rationale

Cervical ectopic pregnancy involves the implantation of the blastocyst within the endocervical canal. This is a rare and potentially dangerous condition because the cervix is highly vascular and lacks the contractile tissue necessary to control bleeding if the pregnancy is disrupted or removed. It accounts for less than 1 percent of ectopic pregnancies. Diagnosis is usually made via ultrasound, and management often requires specialized interventions like uterine artery embolization or methotrexate to avoid a radical hysterectomy.

Choice D rationale

Ovarian ectopic pregnancies occur when the egg is fertilized before it leaves the follicle or when a fertilized egg travels back to the ovary. This accounts for about 1 to 3 percent of ectopic gestations. Distinguishing an ovarian pregnancy from a hemorrhagic corpus luteum cyst can be difficult during clinical assessment. Like tubal pregnancies, they carry a significant risk of rupture and intraperitoneal bleeding, typically requiring surgical excision of the gestational sac or a partial oophorectomy.
