The nurse has conducted a cancer prevention community education program. In evaluating the participants understanding of the carcinogens, which statement indicates an accurate understanding?
Carcinogens are substances that contain cancerous cells.
Substances that change a cell so that it becomes cancerous are potential sources of cancer.
Environmental factors such as sunlight and chemicals can cause cancer to spread.
Carcinogens are in the environment and cannot be avoided.
The Correct Answer is B
A. Carcinogens are substances that contain cancerous cells:
This statement is incorrect. Carcinogens are substances that have the potential to cause cancer, but they do not necessarily contain cancerous cells themselves.
B. Substances that change a cell so that it becomes cancerous are potential sources of cancer:
This is the correct answer. Carcinogens are agents that can induce changes in the genetic material of cells, leading to the development of cancer. They can initiate or promote the process of carcinogenesis.
C. Environmental factors such as sunlight and chemicals can cause cancer to spread:
This statement is not accurate. Carcinogens can contribute to the initiation or promotion of cancer, but the spread of cancer (metastasis) involves complex biological processes and is not directly caused by environmental factors.
D. Carcinogens are in the environment and cannot be avoided:
This statement is not accurate. While carcinogens may be present in the environment, efforts can be made to minimize exposure and adopt preventive measures. Avoidance of known carcinogens and the promotion of a healthy lifestyle can contribute to cancer prevention.

Correct Answer is B
Explanation
A. Administer intravenous fluid bolus as prescribed by the healthcare provider.
While hydration is important, the vital signs provided (elevated heart rate and respiratory rate) are more indicative of potential respiratory distress. Administering fluids may be indicated in certain situations, but it may not address the immediate concern of compromised oxygenation.
B. Apply oxygen at 10 L via non-rebreather mask and monitor pulse oximeter.
This is the correct choice. The client's elevated heart rate and respiratory rate suggest the need for improved oxygenation. Applying oxygen at a high flow rate via a non-rebreather mask is an immediate intervention to address potential respiratory compromise. Monitoring the pulse oximeter provides real-time feedback on oxygen saturation.
C. Medicate for pain and monitor vital signs according to protocol.
Pain management is an important aspect of post-operative care, but the immediate concern in this scenario is the potential for respiratory distress. Administering pain medication alone may not address the primary issue.
D. Encourage the client to splint the incision with a pillow to cough and deep breathe.
While encouraging the client to cough and deep breathe is important for post-thoracotomy care, the elevated vital signs suggest a need for more immediate intervention to ensure adequate oxygenation. Applying oxygen and monitoring the pulse oximeter take precedence.
Correct Answer is A
Explanation
A. Platelet count 40,000 x10/μL (40.000 x109/L):
This is the correct answer. A platelet count of 40,000 x10/μL is significantly below the normal range (usually around 150,000 to 450,000/μL). Low platelet count (thrombocytopenia) can increase the risk of bleeding during and after a surgical procedure. The healthcare provider should be alerted to assess the risk and determine the appropriate management.
B. White blood cells 9,000/μL (9x109/L):
The white blood cell count is within the normal range, and it is not a significant concern for a vertebroplasty procedure.
C. Hematocrit 38% (0.38):
The hematocrit level is within the normal range and is not a significant concern for a vertebroplasty procedure.
D. Hemoglobin 12 g/dL (120 g/L):
The hemoglobin level is within the normal range and is not a significant concern for a vertebroplasty procedure.
