A nurse learns that which of the following is the single biggest risk factor for developing cancer?
Advancing age
Exposure to tobacco
Exposure to occupational chemicals
Infection with an oncovirus.
The Correct Answer is B
Choice A rationale:
While advancing age is a significant risk factor for cancer, it is not considered the single biggest risk factor. The risk of developing cancer does increase with age, primarily due to the accumulation of DNA damage over time. This damage can arise from various sources, including exposure to carcinogens, errors in DNA replication, and oxidative stress. With age, the body's ability to repair DNA damage also declines, making cells more susceptible to cancerous changes.
However, it's important to note that cancer can develop at any age, and even younger individuals can be affected if exposed to other significant risk factors.
Choice B rationale:
Exposure to tobacco is widely recognized as the single biggest risk factor for developing cancer. It is estimated to be responsible for about 25-30% of all cancer deaths worldwide.
Tobacco smoke contains over 70 known carcinogens, which are substances that can damage DNA and lead to cancer. These carcinogens can affect various organs in the body, including the lungs, mouth, throat, esophagus, stomach, pancreas, liver, bladder, kidney, cervix, and colon.
The risk of cancer increases with the amount and duration of tobacco use. Even exposure to secondhand smoke can increase the risk of cancer.
Quitting tobacco use is the most effective way to reduce the risk of cancer.
Choice C rationale:
Exposure to occupational chemicals is a known risk factor for certain types of cancer, such as lung cancer, bladder cancer, and leukemia. However, it is not considered the single biggest risk factor for developing cancer overall.
The risk of cancer from occupational chemicals depends on the specific chemical, the level of exposure, and the duration of exposure.
Workplace safety measures, such as using protective equipment and limiting exposure to hazardous chemicals, can help reduce the risk of cancer.
Choice D rationale:
Infection with certain viruses, known as oncoviruses, can increase the risk of developing certain types of cancer. For example, infection with human papillomavirus (HPV) can increase the risk of cervical cancer, and infection with hepatitis B virus (HBV) can increase the risk of liver cancer.
However, oncoviruses are not considered the single biggest risk factor for developing cancer overall. Vaccines are available to protect against some oncoviruses, such as HPV and HBV.

Correct Answer is A
Explanation
Choice A rationale:
Assessing the patient's adherence to the drug regimen is the most crucial first step in this situation. Here's a comprehensive explanation:
1. Significance of Adherence in HIV Treatment:
Viral Suppression and Disease Progression: Adherence to antiretroviral therapy (ART) is paramount in HIV management. It directly impacts viral suppression, preventing disease progression, and reducing the risk of opportunistic infections and complications. Non-adherence can lead to viral rebound, increased viral load, and potential disease advancement.
Primary Cause of Treatment Failure: Suboptimal adherence is the leading cause of treatment failure in HIV patients. It can result in:
Reduced effectiveness of ART Development of drug resistance Increased healthcare costs Increased risk of transmission
2. Rationale for Prioritizing Adherence Assessment:
Direct Link to Viral Load and Health Status: A sudden decline in health status and a significant increase in viral load strongly suggest potential non-adherence. Assessing adherence early on can:
Identify the root cause of the clinical deterioration
Inform timely interventions to address adherence barriers Prevent further complications
3. Assessing Adherence Thoroughly:
Non-Judgmental Approach: Creating a supportive and non-judgmental environment is essential for honest and accurate assessment.
Open-Ended Questions: Utilize open-ended questions to explore potential challenges and barriers to adherence, such as: Difficulties with medication schedules
Side effects Financial constraints Forgetfulness
Mental health concerns Substance abuse
Lack of social support
Objective Measures: Complement patient reports with objective measures like:
Pill counts
Pharmacy refill records
Medication Event Monitoring Systems (MEMS)
4. Addressing Adherence Barriers:
Tailored Interventions: Based on the assessment findings, develop individualized strategies to enhance adherence, such as: Simplifying medication regimens
Addressing side effects
Providing medication reminders
Offering counseling and support services
Connecting patients with resources
5. Reassessing and Monitoring:
Continuous Evaluation: Regularly reassess adherence and viral load to ensure treatment effectiveness and make adjustments as needed.
Conclusion:
While other options (B, C, D) may provide valuable information, prioritizing adherence assessment is critical to promptly identify and address potential adherence issues, optimize treatment outcomes, and prevent further health decline in HIV patients experiencing viral rebound.
Correct Answer is A
Explanation
Choice A rationale:
Addresses the family's fear directly: By demonstrating how to avoid spreading the disease, the nurse directly addresses the family's primary concern, which is the fear of contracting the infection. This proactive approach provides education and reassurance, empowering the family to make informed decisions about visitation.
Promotes understanding and adherence to precautions: Clear instruction on how to don and doff personal protective equipment, hand hygiene techniques, and other infection control measures increases the likelihood that the family will follow the precautions correctly, reducing the risk of transmission.
Empowers the family to make informed choices: By providing knowledge and skills, the nurse enables the family to feel more confident in their ability to visit safely. This sense of control can help to alleviate anxiety and promote positive coping mechanisms.
Facilitates open communication and trust: The demonstration creates an opportunity for the nurse to answer questions, address concerns, and build rapport with the family. This open dialogue can foster trust and collaboration, which are essential for effective care.
Choice B rationale:
May provide false reassurance: While it's important to offer support and hope, it's not always possible to guarantee that family members will not contract the infection. Absolute reassurances could potentially lead to complacency or disregard for precautions, increasing the risk of transmission.
Fails to address the need for education: Simply stating that the family won't get sick doesn't provide them with the knowledge and skills needed to protect themselves and the client. This lack of understanding could result in accidental transmission.
Choice C rationale:
May pressure the family: Encouraging visitation without addressing underlying fears and concerns could be perceived as pressure, leading to resentment, anxiety, or even avoidance. It's important to respect the family's decision-making process and provide support regardless of their choice.
Doesn't prioritize safety: While emotional support is important, the primary focus should be on ensuring the safety of both the client and the family. Encouraging visitation without proper education and precautions could compromise safety.
Choice D rationale:
Focuses on compliance rather than understanding: Informing the family about legal mandates may come across as authoritarian and could potentially increase anxiety or resistance. It's more effective to focus on the rationale behind the precautions and emphasize their role in protecting both the client and the family.
Misses an opportunity to build trust: Simply stating the rules without engaging in dialogue may hinder open communication and trust-building. Taking a collaborative approach and addressing concerns can lead to better understanding and adherence to precautions.
