Chemotherapy drugs cannot selectively distinguish between normal cells and cancer cells.
True
False
The Correct Answer is A
Choice A: True
Chemotherapy drugs work by targeting rapidly dividing cells, a characteristic of cancer cells. However, they cannot selectively distinguish between cancer cells and normal cells that also divide rapidly, such as those in the bone marrow, digestive tract, and hair follicles. This lack of selectivity leads to the common side effects of chemotherapy, such as hair loss, nausea, and decreased blood cell counts. The inability to differentiate between normal and cancer cells is a significant limitation of traditional chemotherapy.
Choice B: False
This choice is incorrect. If chemotherapy drugs could selectively target only cancer cells, the treatment would have fewer side effects and be more effective. However, the non-selective nature of these drugs means they also damage normal, healthy cells that divide rapidly. This non-selectivity is why patients undergoing chemotherapy often experience a range of side effects, as the treatment impacts both cancerous and healthy cells.

Correct Answer is ["A","B","D","E"]
Explanation
Choice A reason:
Offering peppermint aromatherapy during and after chemotherapy can be an effective non-pharmacological intervention for managing chemotherapy-induced nausea and vomiting (CINV). Aromatherapy with peppermint oil has been shown to reduce nausea and improve comfort in patients undergoing chemotherapy. The scent of peppermint can have a calming effect on the gastrointestinal system, helping to alleviate nausea. This intervention is easy to implement and can be used alongside other treatments to enhance patient comfort.
Choice B reason:
Administering antiemetics before chemotherapy is a standard practice for preventing CINV. Antiemetics, such as 5-HT3 receptor antagonists (e.g., ondansetron), NK1 receptor antagonists (e.g., aprepitant), and corticosteroids (e.g., dexamethasone), are commonly used to prevent nausea and vomiting associated with chemotherapy. These medications are most effective when given prophylactically, before the onset of symptoms. Administering antiemetics before chemotherapy helps to block the pathways that trigger nausea and vomiting, providing better control over these symptoms.
Choice C reason:
Keeping Ms. Anderson NPO (nothing by mouth) for the duration of the chemotherapy is not recommended for managing CINV. Keeping patients NPO can lead to dehydration and malnutrition, which can worsen their overall condition. Instead, patients should be encouraged to eat small, frequent meals and stay hydrated to maintain their strength and well-being. Proper nutrition and hydration are essential for supporting the body’s ability to tolerate chemotherapy and recover from its side effects.
Choice D reason:
Encouraging the patient to eat and drink when not nauseated is an important strategy for managing CINV. Eating small, frequent meals and staying hydrated can help maintain energy levels and prevent dehydration. Patients should be advised to eat bland, easy-to-digest foods and avoid foods that are greasy, spicy, or have strong odors, as these can exacerbate nausea. Encouraging patients to eat and drink when they feel well can help them maintain their nutritional status and improve their overall tolerance to chemotherapy.
Choice E reason:
Offering small sips of ginger ale can help manage nausea. Ginger has natural antiemetic properties and can be effective in reducing nausea and vomiting. Ginger ale, ginger tea, or ginger candies can be soothing and help settle the stomach. This simple intervention can be easily incorporated into the patient’s routine and can provide relief from mild to moderate nausea.
Choice F reason:
Encouraging Ms. Anderson to eat a high-protein meal prior to the chemotherapy infusion is not typically recommended for managing CINV. High-protein meals can be harder to digest and may increase the risk of nausea. Instead, patients should be advised to eat light, bland meals before chemotherapy to minimize the risk of nausea and vomiting. Light meals are easier on the stomach and less likely to trigger gastrointestinal discomfort.
Correct Answer is B
Explanation
Choice A: True
The statement that all patient teaching occurs in a formalized teaching session is not accurate. While formalized teaching sessions are an important aspect of patient education, they are not the only method used. Formal sessions are structured and planned, often involving detailed explanations, demonstrations, and the use of educational materials. These sessions are beneficial for covering complex topics and ensuring that patients and caregivers have a thorough understanding of their health conditions and treatment plans.
Choice B: False
Patient teaching can occur in various settings and formats, not just in formalized teaching sessions. Informal teaching moments are equally important and often occur during routine interactions between healthcare providers and patients. These moments can include brief explanations, answering questions, and providing reassurance during procedures or daily care activities. Informal teaching is flexible and can be tailored to the patient’s immediate needs and readiness to learn, making it a crucial component of effective patient education.
