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."

Answer and Explanation

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 D

Explanation

A. Pyloric stenosis. Pyloric stenosis is a condition that affects infants, causing projectile vomiting due to the narrowing of the pyloric sphincter. It is not a complication of appendicitis and is unrelated to this child's condition.

B. Celiac disease. Celiac disease is an autoimmune disorder triggered by gluten consumption, leading to malabsorption and gastrointestinal symptoms. It is a chronic condition and is not associated with appendicitis or its complications.

C. Gastroenteritis. Gastroenteritis involves inflammation of the stomach and intestines, usually due to viral or bacterial infection. While it can cause abdominal pain, it is not a direct complication of appendicitis but rather a separate condition with similar symptoms.

D. Peritonitis. Peritonitis is the most serious complication of appendicitis and occurs when the inflamed appendix ruptures, leading to infection of the peritoneal cavity. It presents with severe abdominal pain, fever, rigidity, and signs of systemic infection, requiring urgent medical intervention.

A. “Fragile X syndrome follows an autosomal recessive pattern, so both genetic parents must carry the gene mutation for a child to be affected." B. "Since your child has fragile X syndrome, all of your future sons will also have the condition, but your daughters will not be affected." C. “Fragile X syndrome is inherited in a mitochondrial pattern which means it is passed from the pregnant individual to child through the mitochondrial DNA.” D. “Fragile X syndrome is inherited in an X-linked dominant pattern, which means that if a pregnant client carries the gene mutation, each child has a 50% chance of Inheriting the condition."

Correct Answer is D

Explanation

A. “Fragile X syndrome follows an autosomal recessive pattern, so both genetic parents must carry the gene mutation for a child to be affected.” Fragile X syndrome is not autosomal recessive; it is X-linked dominant, meaning it is associated with mutations in the FMR1 gene on the X chromosome. Only one copy of the mutated gene is needed to express the condition.

B. "Since your child has fragile X syndrome, all of your future sons will also have the condition, but your daughters will not be affected." This is incorrect because not all sons will necessarily inherit the condition, and daughters can also be affected, though they often have milder symptoms due to having two X chromosomes.

C. “Fragile X syndrome is inherited in a mitochondrial pattern which means it is passed from the pregnant individual to the child through mitochondrial DNA.” Mitochondrial inheritance involves genes from the mother’s mitochondria, but fragile X syndrome is not inherited this way—it is an X-linked disorder passed down through the X chromosome.

D. “Fragile X syndrome is inherited in an X-linked dominant pattern, which means that if a pregnant client carries the gene mutation, each child has a 50% chance of inheriting the condition.” This is correct. Fragile X syndrome is X-linked dominant, and a parent who carries the full mutation has a 50% chance of passing it to each child. Males typically have more severe symptoms than females due to having only one X chromosome.
