Upon history-taking, the nurse notes that the cough of a patient with lung cancer usually STARTS off to be ___________.

Correct Answer: D

Rationale: The cough of a patient with lung cancer typically starts off as dry and persistent. This is because lung cancer can irritate the airways, leading to a persistent dry cough as an early symptom. As the cancer progresses, the cough may become more productive with blood-tinged or dark yellow sputum. However, in the early stages, the cough is often dry and persistent, which can be a warning sign for healthcare providers to further investigate potential underlying issues such as lung cancer.

Correct Answer: B

Rationale: The best response for the nurse in this situation would be to listen actively to the patient's concerns, acknowledge the lack of information, and offer to address the issue. It is important for healthcare providers to validate the patient's feelings and actively work towards resolving any issues that are causing frustration. By being empathetic and willing to address the problem, the nurse can help improve the patient's experience and build trust in the healthcare team. Dismissing or ignoring the patient's frustration can lead to further dissatisfaction and breakdown in communication. It is crucial for healthcare providers to prioritize open communication and address any concerns or lack of information promptly.

Correct Answer: A

Rationale: Plasma cells are the primary type of cells responsible for the production of antibodies during the humoral immune response. When activated by antigens, B cells differentiate into plasma cells, which are specialized in producing large quantities of antibodies. These antibodies are essential in fighting off infections by binding to antigens and marking them for destruction by other immune cells. T helper cells assist in activating B cells, but the actual production of antibodies is mainly carried out by plasma cells. Memory B cells are involved in mounting a rapid and specific secondary response upon re-exposure to the same antigen. Macrophages play a role in phagocytosis and antigen presentation, but they are not the primary cells responsible for producing antibodies during the humoral immune response.

Correct Answer: B

Rationale: Unstable angina is characterized by chest pain at rest, which is not relieved by nitroglycerin. The ECG findings in unstable angina typically show ST-segment depression or T-wave inversion. It is considered a medical emergency as it can progress to a myocardial infarction. Stable angina, on the other hand, is chest pain or discomfort that occurs with exertion and is relieved by rest or medications like nitroglycerin. Acute myocardial infarction would typically present with ST-segment elevation on ECG, while Prinzmetal's angina is characterized by transient ST-segment elevation due to coronary artery vasospasm.

Correct Answer: D

Rationale: It is important for the nurse to acknowledge the patient's preference and respect their choice. By responding with "So then you would prefer to speak with your doctor?" the nurse is showing understanding and willingness to accommodate the patient's request. This response helps to maintain a positive and respectful interaction with the patient.
