A nurse is assessing a postpartum mother who is in the taking-in phase of Rubin's stages of maternal role adaptation. Which of the following behaviors is most indicative of the taking-in phase?

A. "You should be encouraged to eat more of these items to satisfy cravings." is incorrect because consuming non-food items like ice, clay, or dirt can be harmful. These substances may contain toxins or pathogens and can interfere with nutrient absorption. Encouraging this behavior would be unsafe.

B. "This is a normal behavior during pregnancy and does not require intervention." is incorrect because while cravings are common in pregnancy, PICA is an abnormal eating behavior involving non-food items and requires assessment and intervention due to potential health risks.

C. "This behavior, called PICA, may lead to nutritional deficiencies and should be assessed." is correct. PICA is the recurrent consumption of non-nutritive substances and is often associated with iron deficiency anemia and other nutritional deficiencies. The nurse should assess for nutritional status, laboratory abnormalities, and educate the client on potential risks to both mother and fetus.

D. "PICA only occurs in the first trimester and will resolve on its own." is incorrect because PICA can occur at any time during pregnancy and may persist throughout gestation if untreated. It does not resolve spontaneously in all cases.

A. Barking cough and inspiratory stridor, especially at night is incorrect because this is characteristic of croup, a respiratory condition, not tetralogy of Fallot. Tetralogy of Fallot primarily affects cardiac blood flow, not the upper airway.

B. Bradycardia and hypotension following minor activity or mild stress is incorrect because children with tetralogy of Fallot typically develop tachycardia in response to hypoxia or stress, rather than bradycardia. Hypotension is not a hallmark sign unless there is shock or severe complications.

C. Cyanosis that worsens during crying or feeding, often relieved by squatting is correct because children with tetralogy of Fallot have right-to-left shunting due to the combination of ventricular septal defect, pulmonary stenosis, overriding aorta, and right ventricular hypertrophy. This shunting reduces pulmonary blood flow, leading to cyanosis, which often becomes more pronounced during periods of increased oxygen demand, such as crying or feeding. Squatting increases systemic vascular resistance, temporarily reducing the shunt and improving oxygenation, which is known as a “Tet spell” relief maneuver.

D. Peripheral edema and hepatomegaly during exertion or prolonged play is incorrect because these signs are more typical of heart failure rather than tetralogy of Fallot in a child without chronic severe heart failure. Tetralogy of Fallot presents primarily with cyanosis and hypoxic spells.
