Correct Answer: A

Rationale: Nausea and vomiting are common adverse effects of chemotherapy. Administering an antiemetic helps to prevent or reduce these symptoms in patients undergoing chemotherapy. By managing nausea and vomiting, the patient's overall well-being and quality of life during treatment can be improved. Therefore, providing an antiemetic medication is essential in combating these adverse effects and promoting patient comfort and compliance with treatment.

Correct Answer: B

Rationale: A fibroadenoma is a benign breast tumor commonly found in young women. In most cases, a fibroadenoma does not require radiation therapy. However, the patient might be referred for a biopsy to confirm the diagnosis and rule out any potential malignancy. While fibroadenomas can be related to hormonal changes in the body, they are not directly linked to the use of oral contraceptives. Recognizing this implication of the patient's diagnosis is essential for providing appropriate care and follow-up.

Correct Answer: B

Rationale: It is crucial for the nurse to monitor that all furniture remains in the same position in the hospitalized patient's room. For a patient with impaired vision who needs to create a mental picture of the room to mobilize independently and safely, any changes in the position of furniture can disrupt this mental map and potentially lead to accidents or falls. By ensuring that all furniture remains unchanged, the nurse supports the patient's ability to navigate the room confidently and without obstacles. This monitoring helps promote the patient's safety and independence during their stay in the hospital.

Correct Answer: B

Rationale: The patient's frustration with chronic nasal congestion, anosmia, and inability to concentrate indicates difficulty coping with the long-term nature of her condition and the impact it has on her daily life. Additionally, her desire for relief suggests a need for environmental modifications to help manage her symptoms. This nursing diagnosis encompasses the patient's emotional response to her condition, as well as the potential need for changes in her surroundings to better support her health and well-being.

Correct Answer: B

Rationale: Smoking cessation most directly addresses the leading cause of cancer deaths in North America, which is lung cancer. Tobacco use, particularly cigarette smoking, is the primary cause of lung cancer. By helping individuals quit smoking, the public health nurse is targeting the main risk factor for lung cancer and therefore addressing the root cause of the issue. This intervention has the potential to have a significant impact on reducing cancer-related deaths in the community. Monthly self-breast exams, annual colonoscopies, and monthly testicular exams are important for detecting breast, colon, and testicular cancers respectively, but they do not directly address the leading cause of cancer deaths in North America.
