Correct Answer: A

Rationale: Depression can occur in clients with heart failure, especially in older adults. When a client expresses thoughts of being a burden and death, it is crucial for the nurse to address these concerns. Offering to talk more about the client's feelings provides an opportunity for open communication and a deeper understanding of the client's emotions. Open-ended questions like the one in choice A encourage the client to express themselves freely, leading to better assessment and client-centered care. Choices B and C fail to address the client's emotional distress directly, and choice D diverts the focus without addressing the client's immediate concerns.

Rationale: Client-centered care focuses on individualizing care to meet the client's unique needs, preferences, and values. Assessing for cultural influences affecting healthcare allows the healthcare professional to provide culturally sensitive and competent care, respecting the client's beliefs and practices. It promotes effective communication, understanding, and collaboration, essential components of client-centered care.

Correct Answer: C

Rationale: The most appropriate action for the nurse in this scenario is to teach the client about factor V Leiden testing. Factor V Leiden is an inherited thrombophilia that can lead to abnormal clotting events, including pulmonary embolism (PE). In a case where a client has no known risk factors for PE, testing for this genetic disorder is crucial to determine if it is a contributing factor. Encouraging the client to walk or referring them to smoking cessation classes, while beneficial for overall health, are not directly relevant to the development of a PE in this specific case. While it is true that sometimes no cause for a disease is found, prematurely assuming this without appropriate investigations may lead to missed opportunities for preventive measures or treatments.

Correct Answer: C

Rationale: The pain of a myocardial infarction (MI) is often accompanied by shortness of breath and feelings of fear or anxiety. Unlike stable angina, the pain of an MI typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Additionally, it can occur without a known cause, unlike stable angina which often has a trigger such as exertion.
