Correct Answer: C

Rationale: The correct answer is C. Taking iron supplements with orange juice, which contains vitamin C, enhances the absorption of iron, making the treatment more effective. Choices A, B, and D are incorrect because taking ferrous sulfate with milk, calcium-rich foods, or breakfast may hinder iron absorption due to interactions with calcium or other substances that compete with iron absorption.

Correct Answer: D

Rationale: Signs of magnesium sulfate toxicity include respirations less than 12/min, urinary output less than 25 mL/hr, and decreased level of consciousness. These signs indicate potential overdose of magnesium sulfate and require immediate attention to prevent further complications. Reporting these signs promptly is crucial to ensure the client's safety and well-being. Choice D, 'All of the above,' is the correct answer as all the listed findings are indicative of magnesium sulfate toxicity. Choices A, B, and C individually represent different signs of toxicity, making them incorrect on their own. Therefore, the nurse should be vigilant in identifying and reporting all these signs to prevent adverse outcomes.

Correct Answer: A

Rationale: During early pregnancy, nausea and vomiting in the morning are common symptoms. Eating crackers or plain toast before getting out of bed can help manage morning nausea by stabilizing blood sugar levels. This simple and easily digestible snack can alleviate symptoms by providing some sustenance to the stomach before fully waking up and moving around. Choices B, C, and D are incorrect. Waking up during the night to eat a snack may disrupt sleep patterns, skipping breakfast can worsen symptoms by allowing the stomach to remain empty for longer periods, and eating a large evening meal may exacerbate morning nausea due to increased stomach contents.

Correct Answer: B

Rationale: A weight gain of 3.6 kg (8 lb) in the first trimester is excessive and should be reported to the provider for further evaluation. Excessive weight gain in the first trimester can be a sign of potential issues that need monitoring and intervention to ensure the well-being of both the mother and the baby. Choices A, C, and D represent weight gains that are within normal ranges for the respective trimesters and do not raise immediate concerns for reporting to the provider.

Correct Answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.
