Practice Question
A nurse strongly encourages a pregnant client to avoid eating swordfish and tilefish because these fish contain which component?
Answer Choices:
Correct Answer:
mercury, which could harm the developing fetus if eaten in large amounts
Rationale:
🟡 Swordfish, tilefish, shark, and king mackerel are known to contain high levels of methylmercury, a neurotoxic substance that can cross the placenta and harm fetal brain and nervous system development.
🟡 Pregnant individuals are advised to avoid high-mercury fish and instead choose low-mercury alternatives like salmon, tilapia, and sardines, which are safer and still rich in omega-3 fatty acids beneficial for fetal growth.
🟡 Mercury exposure in utero is associated with cognitive deficits, motor delays, and language development issues in infants.
🟡 The FDA and EPA recommend consuming 2–3 servings of low-mercury fish per week during pregnancy while strictly avoiding high-mercury varieties.
🟡 This precaution is essential for protecting fetal neurological development without sacrificing the benefits of fish intake.
