A 35-year-old female client is requesting information about mammograms and breast cancer. She isn't considered at high risk for breast cancer. What should the nurse tell this client?

Correct Answer: D

Rationale: According to the American Cancer Society guidelines, women with average risk for breast cancer should start getting mammograms every 2 years starting at age 40. Since the client is not considered at high risk for breast cancer, this recommendation applies to her. Regular mammograms are important for early detection of breast cancer, even in those at average risk. It is also important for the client to perform monthly breast self-exams and report any changes or concerns to her healthcare provider.

Correct Answer: A

Rationale: Tamoxifen (Nolvadex) is associated with the potential side effect of retinopathy, which can present as changes in vision. Retinopathy is a serious condition that can lead to vision loss. Therefore, it is crucial for the client to report any vision changes immediately to their healthcare provider for further evaluation and management. Reporting this adverse reaction promptly can help prevent serious complications and ensure the client's safety and well-being.

Correct Answer: B

Rationale: The first step toward effective cancer control is changing habits and customs that predispose individuals to cancer. Prevention is key in reducing the incidence of cancer. By addressing factors like smoking, poor diet, lack of physical activity, excessive alcohol consumption, and exposure to carcinogens in the environment, the risk of developing cancer can be significantly reduced. Education and awareness play a crucial role in encouraging individuals to adopt healthier lifestyles and behaviors to minimize their cancer risk. While screening and early detection are also important aspects of cancer control, prevention through lifestyle modifications is the fundamental strategy in reducing the burden of cancer in the population.

Correct Answer: A

Rationale: In this scenario, the patient developing a low-grade fever post-operatively along with diminished breath sounds could indicate the possibility of atelectasis or pneumonia. The most appropriate actions for the nurse to take to prevent complications in this situation would be to encourage coughing and deep breathing (to help clear secretions and improve lung expansion) and ambulate the patient as ordered (to promote lung ventilation and prevent further complications). Administering antibiotics, acetaminophen for fever management, and decreasing fluid intake may be considered based on the healthcare provider's assessment and orders, but the immediate nursing interventions to address the presenting symptoms are encouraging coughing and deep breathing and ambulating the patient.

Correct Answer: A

Rationale: Hypokalemia, or low potassium levels, predisposes the patient to digoxin toxicity because potassium is essential for proper digoxin metabolism. Potassium competes with digoxin for binding sites on sodium-potassium ATPase pumps in the myocardial cells. When potassium levels are low, digoxin binding is increased, leading to an increased risk of digoxin toxicity. Monitoring and correcting hypokalemia are important in patients taking digoxin to reduce the risk of toxicity. Hyperkalemia, on the other hand, can increase the risk of digoxin toxicity by affecting electrophysiological properties of the heart, but hypokalemia is the most significant imbalance predisposing to digoxin toxicity.
