What is the most common symptom of testicular cancer?
- A. Low back pain
- B. Fatigue
- C. Painless, firm scrotal mass or swelling
- D. Mild to moderate pressure to the scrotum
Correct Answer: C
Rationale: The correct answer is C: Painless, firm scrotal mass or swelling. This is the most common symptom of testicular cancer because it often presents as a painless lump or swelling in the testicle. Other choices are incorrect because low back pain (A) is not a common symptom of testicular cancer, fatigue (B) is a non-specific symptom that can occur in many conditions, and mild to moderate pressure to the scrotum (D) is not a typical symptom of testicular cancer.

What is the most important action to be taken by the community health nurse (CHN) who wishes to decrease childhood obesity?
- A. Lobbying legislators to enact stronger legislation regarding unhealthy lunches and food from snack machines in schools
- B. Increasing availability of nutrition programs in which schoolchildren are taught to make healthy food choices
- C. Involving the entire family in the management of obesity in a child
- D. Providing after-school activities and summer camps that focus on diet and exercise
Correct Answer: C
Rationale: The correct answer is C. Involving the entire family in the management of obesity in a child is the most important action because family support and involvement are crucial for sustainable behavior change in children. The family plays a significant role in shaping a child's habits and lifestyle choices. By engaging the entire family, the community health nurse can create a supportive environment where healthy behaviors are encouraged and reinforced consistently. This approach addresses the root causes of childhood obesity by promoting healthy eating habits and physical activity within the child's daily life, rather than relying solely on external interventions like legislation or programs.
Choice A is less effective because while legislation can create a healthier environment, it may not directly address the underlying family dynamics influencing a child's behavior. Choice B is important but may not be as effective as involving the family since parental influence extends beyond school-based programs. Choice D is valuable but may not address the core issue of family involvement, which is crucial for sustainable behavior change.
Which of the following would be considered part of a transformational leadership style?
- A. A group leader uses rewards to engage others.
- B. A group leader uses personal charisma to motivate followers.
- C. A group leader focuses on day-to-day tasks.
- D. Minimal or no direction is provided by the group leader.
Correct Answer: B
Rationale: The correct answer is B because transformational leadership involves inspiring and motivating followers through personal charisma and vision. Charismatic leaders are able to influence and inspire others to achieve common goals. Choice A focuses on transactional leadership, which involves rewards for performance. Choices C and D are characteristics of laissez-faire leadership, where the leader is hands-off or focused solely on tasks, not inspiring transformation.
Women who develop vaginal fungal infections (commonly referred to as yeast infections) usually have a history of having been prescribed antibiotics for bacterial infections. Which component of the epidemiological triangle (agent–host–environment) contributes most to the development of vaginal infections?
- A. Agent
- B. Environment
- C. Host
- D. Agent and host
Correct Answer: C
Rationale: Rationale: The correct answer is C: Host. Antibiotics disrupt the normal vaginal flora, creating an environment conducive to yeast overgrowth. The host's susceptibility to infection due to altered microbiota is the primary factor in developing vaginal fungal infections. The agent (yeast) and the environment (vaginal environment) play secondary roles. Choice A is incorrect because the yeast is the agent causing the infection, but it is the host's response that determines infection development. Choice B is incorrect because the vaginal environment is affected by antibiotics, but it is the host's response that leads to infection. Choice D is incorrect because while both agent and host are involved, it is the host's susceptibility that is the key factor.
The ability to access, comprehend, evaluate, and communicate information as a way to promote, maintain and improve health in a variety of settings across the life-course is defined as:
- A. Health promotion
- B. Health literacy
- C. Health advocacy
- D. Health maintenance
Correct Answer: B
Rationale: The correct answer is B: Health literacy. Health literacy involves the skills needed to access, understand, evaluate, and communicate health information to make informed decisions and promote health. This definition aligns with the ability to comprehend and utilize health information effectively. Health promotion (A) focuses on strategies to improve health outcomes, health advocacy (C) involves promoting health policies and practices, and health maintenance (D) refers to activities that sustain health, but these choices do not encompass the comprehensive definition provided in the question.
Which public health service best represents primary prevention?
- A. Administering the influenza vaccine to a group of seniors
- B. Initiating an infant car seat safety screening program for parents in low-income housing
- C. Starting a rehabilitation clinic for middle-aged adults who reside in low-income housing
- D. Setting up a blood pressure screening clinic at the local mall
Correct Answer: B
Rationale: The correct answer is B because initiating an infant car seat safety screening program for parents in low-income housing best represents primary prevention. Primary prevention aims to prevent the occurrence of a disease or injury before it occurs. In this case, educating parents on proper car seat safety practices helps prevent injuries to infants in the first place. Administering the influenza vaccine (A) is an example of secondary prevention as it aims to detect and treat existing conditions. Starting a rehabilitation clinic (C) and setting up a blood pressure screening clinic (D) are also examples of secondary prevention as they focus on managing existing health conditions rather than preventing them.
