Which fluid is used in the management of gastrointestinal tract (GIT) loss and burns?
- A. Ringer's lactate
- B. Normal saline
- C. Dextrose
- D. Blood
Correct Answer: A
Rationale: The correct answer is A: Ringer's lactate. Ringer's lactate is used in managing GIT loss and burns due to its balanced electrolyte composition, which closely resembles the electrolyte content of plasma. It helps replace lost fluids and maintain electrolyte balance. Normal saline (B) lacks bicarbonate and may lead to metabolic acidosis. Dextrose (C) provides energy but does not address fluid and electrolyte losses. Blood (D) is not typically used for fluid resuscitation in these cases unless there is severe hemorrhage.

What is a primary objective of public health?
- A. Lowering the prevalence of chronic diseases
- B. Eliminating health disparities among populations
- C. Delivering health education
- D. Extending life expectancy
Correct Answer: B
Rationale: The correct answer is B: Eliminating health disparities among populations. This is the primary objective of public health as it focuses on ensuring that all individuals have equal access to healthcare and resources to achieve optimal health outcomes. By addressing disparities, public health aims to promote health equity and reduce inequalities in health status. Lowering chronic diseases (A) and extending life expectancy (D) are important goals but not the primary objective. Delivering health education (C) is a strategy within public health but not the main objective.
Which of the following are major veins commonly used in parenteral cannulation?
- A. Basilic vein
- B. Femoral vein
- C. Subclavian vein
- D. Aorta
Correct Answer: D
Rationale: I'm sorry, but the correct answer provided (D: Aorta) is actually incorrect in this context. The major veins commonly used in parenteral cannulation are A: Basilic vein, B: Femoral vein, and C: Subclavian vein. The aorta is a major artery, not a vein, and is not typically used for parenteral cannulation due to its high pressure and risk of complications. It's important to understand the differences between veins and arteries when considering cannulation sites.
Which action demonstrates health advocacy?
- A. Providing direct patient care
- B. Working to change policies that affect health care access
- C. Educating patients about their health conditions
- D. Conducting health screenings in underserved areas
Correct Answer: B
Rationale: The correct answer is B because advocating for health involves addressing systemic issues that impact health outcomes. Changing policies can lead to broader and sustainable improvements in healthcare access for all individuals. Providing direct patient care (A) focuses on individual needs, educating patients (C) is important but not necessarily advocacy, and conducting health screenings (D) is part of preventive care but not advocacy for systemic change.
Which is an example of a secondary prevention strategy?
- A. Administering immunizations to prevent disease
- B. Conducting health screenings to detect early signs of disease
- C. Providing rehabilitation services to prevent complications
- D. Educating the public about healthy lifestyle choices
Correct Answer: B
Rationale: Step-by-step rationale:
1. Secondary prevention aims to detect and treat diseases at an early stage.
2. Health screenings help identify early signs of disease before symptoms appear.
3. Early detection allows for prompt intervention to prevent disease progression.
4. Administering immunizations (A) is an example of primary prevention.
5. Providing rehabilitation services (C) is an example of tertiary prevention.
6. Educating the public (D) focuses on promoting healthy behaviors, also a primary prevention strategy.
Summary:
Option B is correct as it aligns with the goal of secondary prevention by detecting diseases early. Options A, C, and D are incorrect as they represent primary prevention, tertiary prevention, and health promotion strategies, respectively.
Which best describes the role of a community health nurse in promoting health?
- A. Advocating for health policy changes
- B. Providing direct care to individuals and families
- C. Educating the community about healthy lifestyles
- D. Conducting research on community health issues
Correct Answer: A
Rationale: The correct answer is A because advocating for health policy changes is a key role of community health nurses in promoting health at a population level. They work to influence policies that address social determinants of health and improve overall community well-being. Providing direct care (B) is more aligned with clinical nursing roles. Educating the community (C) is important but not the primary role of a community health nurse. Conducting research (D) may inform practice but is not the primary function of promoting health in the community.
