A mother of a child with a neural tube defect asks the nurse what she can do to decrease the chances of having another baby with a neural tube defect. What is the best response by the nurse?

Correct Answer: A

Rationale: The correct answer is A: 'Folic acid should be taken before and after conception.' Folic acid supplementation before and during early pregnancy has been shown to significantly reduce the risk of neural tube defects. Choice B is incorrect because while multivitamin supplements are beneficial during pregnancy, the specific focus for preventing neural tube defects is on folic acid. Choice C is a general statement about a well-balanced diet and does not specifically address neural tube defects. Choice D is incorrect as it focuses on dietary iron, which is important for overall health but not specifically proven to prevent neural tube defects.

Correct Answer: A

Rationale: The correct answer is A: Spinach. Spinach is high in oxalate, a compound that can contribute to the formation of calcium oxalate kidney stones. Therefore, advising the client to avoid spinach is crucial in reducing the risk of stone recurrence. Bananas (choice B) are not high in oxalate and do not directly contribute to the formation of calcium oxalate stones, so they do not need to be avoided. Similarly, choices C and D, chicken, and rice, are not typically associated with high oxalate content, making them safe choices and do not need to be avoided specifically to prevent calcium oxalate kidney stones.

Correct Answer: B

Rationale: The correct answer is B: Crackles in the lungs. Crackles in the lungs indicate pulmonary congestion, a serious complication of left-sided heart failure. The presence of crackles suggests fluid accumulation in the lungs, impairing gas exchange and potentially leading to respiratory distress. Immediate intervention is necessary to prevent worsening respiratory function. Choices A, C, and D are incorrect: Peripheral edema is a common finding in heart failure but may not be as acutely concerning as pulmonary congestion. Jugular vein distention is associated with right-sided heart failure, not left-sided heart failure. Hepatomegaly is often seen in liver conditions and right-sided heart failure, not specifically left-sided heart failure.

Correct Answer: D

Rationale: Altered mental status would be the most concerning symptom in a client with liver cirrhosis. It may indicate hepatic encephalopathy, a serious complication requiring immediate intervention. While jaundice, ascites, and hepatomegaly are common in liver cirrhosis, they do not directly correlate with the urgency and severity of hepatic encephalopathy as altered mental status does. Therefore, altered mental status takes priority for immediate attention and intervention.

Correct Answer: C

Rationale: In a client with rheumatoid arthritis, the presence of fever is most concerning because it may indicate an infection or systemic involvement, necessitating immediate attention. Morning stiffness and joint deformities are common manifestations of rheumatoid arthritis itself and are expected findings in these clients. Weight loss can occur in rheumatoid arthritis due to various factors such as decreased appetite or systemic inflammation, but it is not as acutely concerning as fever, which may signal a more urgent issue.
