Correct Answer: C

Rationale: The correct answer is C because the severity of an anaphylactic reaction can vary greatly from one episode to another in the same patient. Anaphylactic reactions are unpredictable and can be influenced by various factors such as the amount of allergen exposure, individual immune response, underlying health conditions, and concurrent medications. Therefore, it is not possible to reliably gauge the severity of a patient's anaphylactic reaction even if it has occurred repeatedly in the past. Choice A is incorrect because the onset of symptoms alone is not a reliable predictor of the severity of the reaction. Choice B is incorrect as well because there is no set formula to predict that the reaction will be one-third more severe than the patient's last reaction. Choice D is incorrect because stating that the reaction will generally be slightly less severe than the last reaction is also not accurate or supported by evidence.

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: D

Rationale: The correct answer is D: Bilateral mastectomy. This intervention involves removing both breasts to reduce the risk of developing breast cancer in the future. For a woman with a history of breast cancer in one breast, opting for bilateral mastectomy can significantly decrease the likelihood of cancer recurrence. This proactive approach is often recommended for individuals with a high risk of developing breast cancer. Explanation for why the other choices are incorrect: A: More aggressive chemotherapy - Chemotherapy is typically used to treat existing cancer cells, not as a prophylactic measure to prevent cancer. B: Left mastectomy - This option only removes the affected breast, not addressing the risk of cancer developing in the other breast. C: Radiation therapy - While radiation therapy can be used as part of the treatment for breast cancer, it is not a prophylactic measure to prevent future cancer development in the contralateral breast.

Correct Answer: A

Rationale: The correct answer is A: Breech presentation. Obesity can lead to a larger fetus, increasing the risk of breech presentation. The rationale is that excess fat can hinder the baby's ability to turn head down. Other choices are incorrect because: B: Ectopic pregnancy is not related to obesity, C: Birth defects can be influenced by maternal health but are not directly linked to obesity, and D: Venous thromboembolism is more associated with immobility and hypercoagulable states rather than obesity.

Correct Answer: B

Rationale: The correct answer is B: Nausea and vomiting. Chemotherapy commonly causes gastrointestinal side effects, such as nausea and vomiting, due to its impact on rapidly dividing cells in the digestive tract. This adverse effect can significantly impact a patient's quality of life and adherence to treatment. Pruritis (A), itching, is less common and usually not a primary side effect of chemotherapy. Altered glucose metabolism (C) is a potential effect of some chemotherapeutic agents but is not the most common adverse effect. Confusion (D) is not typically associated with chemotherapy and is more commonly seen with other medications or medical conditions.
