A nurse is reinforcing teaching to a newly hired nurse about anencephaly. Which of the following statements should the nurse make?
"Anencephaly affects male fetuses more than female fetuses.”
"Cancer during pregnancy is a risk factor for anencephaly."
"These defects occur in the embryonic stage of pregnancy."
"Most newborns who have anencephaly survive 1 month."
The Correct Answer is C
A. "Anencephaly affects male fetuses more than female fetuses." Anencephaly occurs more frequently in female fetuses than in males. Studies suggest a slightly higher prevalence in female infants, though the exact reason is unclear.
B. "Cancer during pregnancy is a risk factor for anencephaly." There is no known link between cancer during pregnancy and anencephaly. The primary risk factors include folic acid deficiency, maternal diabetes, and exposure to teratogens (e.g., certain medications, high temperatures, or environmental toxins).
C. "These defects occur in the embryonic stage of pregnancy." Anencephaly is a neural tube defect (NTD) that occurs during the embryonic stage, specifically between weeks 3 and 4 of gestation. During this period, the neural tube fails to close properly, leading to incomplete development of the brain and skull.
D. "Most newborns who have anencephaly survive 1 month." Anencephaly is almost always fatal, with most affected newborns dying within hours to days after birth. There is no cure, and long-term survival is extremely rare due to the severe brain malformation.

Correct Answer is A
Explanation
A. Amenorrhea. Anorexia nervosa is associated with severe weight loss and malnutrition, leading to hormonal imbalances that disrupt the menstrual cycle. Decreased estrogen levels result in amenorrhea, which is a hallmark symptom of the disorder and a significant reproductive health concern.
B. Increased fertility. Anorexia nervosa typically leads to hormonal imbalances, including decreased levels of gonadotropins and estrogen, which suppress ovulation and reduce fertility rather than increasing it.
C. Early onset of puberty. Malnutrition and low body fat delay puberty rather than accelerating it. Adolescents with anorexia nervosa may experience delayed menarche and stunted growth due to inadequate nutrition.
D. Pelvic inflammatory disease (PID). PID is usually caused by sexually transmitted infections and is not directly associated with anorexia nervosa. The primary reproductive concern in anorexia is hormonal disruption leading to menstrual irregularities.
Correct Answer is ["3.8"]
Explanation
Convert the child's weight from pounds to kilograms:
Formula:
kg = lb / 2.2
= 22 lb / 2.2 lb/kg
= 10 kg
Calculate the total daily dose of dexamethasone:
Total daily dose (mg) = Dose (mg/kg/day) × Weight (kg)
= 1.5 mg/kg/day × 10 kg
= 15 mg/day
Calculate the dose to be administered every 6 hours:
Dose per interval (mg/dose) = Total daily dose (mg/day) / Number of doses per day
= 15 mg/day / 4 doses/day
= 3.75 mg/dose
Calculate the volume of dexamethasone oral solution to administer:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
= 3.75 mg / 1 mg/mL
= 3.75 mL
Round to the nearest tenth:
3.75 mL rounded to the nearest tenth is 3.8 mL.
The nurse should administer 3.8 mL per dose.
