Correct Answer: D

Rationale: The correct answer is D, balancing calories. This is because the ChooseMyPlate program emphasizes the importance of maintaining a balance between the calories consumed and calories expended for overall health and weight management. By balancing calories, individuals can ensure they are meeting their nutritional needs without overeating or consuming excess calories. A: Balancing sodium and potassium is important for managing blood pressure, but this is not a specific guideline of the ChooseMyPlate program. B: Decreasing water consumption is not a guideline of the ChooseMyPlate program. Adequate hydration is essential for overall health. C: Increasing portion size is not recommended in the ChooseMyPlate program. It emphasizes portion control and eating appropriate serving sizes of different food groups.

Correct Answer: B

Rationale: The correct order is B: Kidney, ureters, bladder, urethra. 1. Kidneys filter blood and produce urine. 2. Ureters transport urine from kidneys to bladder. 3. Bladder stores urine until expelled. 4. Urethra carries urine from bladder out of the body. Other choices are incorrect because they do not follow the anatomical flow of urine through the urinary system.

Correct Answer: D

Rationale: The correct answer is D: Personality changes. Metastases to the brain can affect cognitive function and behavior, leading to personality changes. This is due to the impact on specific areas of the brain responsible for personality and behavior. Chronic pain (A) is more commonly associated with advanced cancer and not specific to brain metastases. Respiratory distress (B) is more likely related to lung cancer itself, not brain metastases. Fixed pupils (C) may indicate brainstem involvement, but personality changes are a more direct and common manifestation of brain metastases.

Correct Answer: C

Rationale: The correct answer is C because folic acid is crucial in preventing neural tube defects and anemia in the developing fetus. The nurse should teach the expectant mother about the importance of taking folic acid supplements before and during pregnancy. Folic acid is essential for proper cell division and growth, reducing the risk of birth defects. Choice A is incorrect because calcium intake is important throughout pregnancy, not just in the first trimester. Choice B is incorrect as protein intake should be adequate to support maternal and fetal growth, not decreased. Choice D is incorrect as excessive intake of vitamins and minerals can be harmful to the mother and the baby. In summary, the expectant mother should be educated on the importance of folic acid supplementation to prevent birth defects and anemia, while also ensuring a balanced diet with all essential nutrients.

Correct Answer: A

Rationale: Rationale for Correct Answer A: Applying a protective eye shield at night is crucial for a patient with Bell's palsy to prevent corneal abrasions due to incomplete eyelid closure. This action helps protect the eye from dryness and injury, which can occur due to decreased blinking and moisture. It is essential to maintain eye health and prevent complications. Summary of Incorrect Choices: B: Chewing on the affected side does not prevent unilateral neglect in Bell's palsy. Instead, encouraging balanced chewing and facial exercises would be more beneficial. C: Avoiding the use of analgesics is not necessary for Bell's palsy management unless contraindicated, as pain management may be required for associated symptoms. D: Avoiding brushing the teeth is not recommended. Good oral hygiene is important for overall health, including maintaining oral health during Bell's palsy.
