The nurse is caring for a pregnant patient who is 34 weeks gestation and is concerned about the safety of using herbal remedies. What is the nurse's most appropriate response?

Correct Answer: B

Rationale: The correct answer is B because pregnant patients should avoid all herbal remedies without consulting their healthcare provider. During pregnancy, there can be potential risks associated with herbal remedies, as their safety and efficacy are not well studied. It is crucial for healthcare providers to assess the individual patient's medical history and current health status before recommending any herbal remedies. Choice A is incorrect because not all herbal remedies are safe during pregnancy, regardless of being natural. Choice C is incorrect because herbal remedies can pose risks throughout pregnancy, not just in the first trimester. Choice D is incorrect because the safety of herbal remedies cannot be guaranteed solely by purchasing them from a reputable source. Consulting a healthcare provider is essential to ensure the safety of both the mother and the baby.

Correct Answer: B

Rationale: The correct answer is B: Increased blood volume and decreased blood pressure. At 28 weeks gestation, the pregnant patient's blood volume significantly increases to support the developing fetus, causing a relative decrease in blood pressure when standing up (orthostatic hypotension). This can lead to lightheadedness and fainting. Dehydration and electrolyte imbalance (choice A) can contribute to these symptoms but are less likely in a pregnant patient. Iron-deficiency anemia (choice C) can cause similar symptoms but is less common at 28 weeks gestation. Hyperglycemia from gestational diabetes (choice D) typically presents with other symptoms like excessive thirst and urination, rather than lightheadedness and fainting.

Correct Answer: B

Rationale: The correct answer is B: Assess the patient's hemoglobin and hematocrit levels to check for anemia. Fatigue and weakness in pregnancy can be symptoms of anemia, a common condition due to increased blood volume demands. By checking hemoglobin and hematocrit levels, the nurse can confirm or rule out anemia as the cause. Resting alone may not address the underlying issue, and high-calorie diet or regular exercise may not be appropriate if anemia is present. It is crucial to identify the root cause to provide the most effective intervention.

Correct Answer: C

Rationale: The correct answer is C because excessive weight gain during pregnancy can indeed increase the risk of complications such as gestational diabetes and preeclampsia. By emphasizing this point, the nurse can help the patient understand the importance of monitoring their weight gain to promote a healthy pregnancy. Choice A is not as strong because it focuses more on discussing concerns with the healthcare provider rather than the specific risks associated with excessive weight gain. Choice B is incorrect as weight gain during pregnancy should be monitored and managed appropriately. Choice D is also incorrect as it suggests limiting caloric intake, which may not be safe or appropriate for the patient and her developing fetus.

Correct Answer: A

Rationale: The correct answer is A: Hypotension due to pregnancy-related changes in circulation. During pregnancy, blood volume increases, leading to decreased blood pressure when standing. This can cause dizziness and fainting. Dehydration and electrolyte imbalance (B) may cause similar symptoms but are less common in pregnant patients. Iron-deficiency anemia (C) typically presents with fatigue and weakness, not dizziness and fainting. Gestational diabetes (D) usually manifests as high blood sugar levels, not low blood pressure leading to dizziness and fainting.
