What is the primary focus of community health nursing?
- A. Individual patient care
- B. Hospital-based care
- C. Community-wide health promotion and disease prevention
- D. Specialized medical treatment
Correct Answer: C
Rationale: The correct answer is C: Community-wide health promotion and disease prevention. Community health nursing focuses on promoting health and preventing diseases within the community as a whole through education, advocacy, and collaboration. This includes addressing social determinants of health and implementing population-based interventions. Choice A is incorrect because community health nursing goes beyond individual patient care. Choice B is incorrect as it is more focused on acute care within hospital settings. Choice D is incorrect as it pertains to specialized medical treatment rather than the broader scope of community health nursing. In summary, the primary focus of community health nursing is on improving the health of the entire community through preventative measures and health promotion initiatives.

Which of the following interventions is an example of tertiary prevention?
- A. Vaccination campaigns
- B. Health education seminars
- C. Physical rehabilitation programs
- D. Early disease screening
Correct Answer: C
Rationale: Tertiary prevention focuses on managing and improving quality of life for individuals with existing health conditions. Physical rehabilitation programs fall under this category as they help individuals recover and regain functioning after an illness or injury. This intervention aims to prevent further complications and disabilities. Vaccination campaigns (A) and health education seminars (B) are examples of primary and secondary prevention, focusing on preventing diseases before they occur or detecting them early. Early disease screening (D) is also a form of secondary prevention, aiming to detect diseases in their early stages before symptoms appear.
Which of the following is an essential nutrient required for preventing neural tube defects?
- A. Iron
- B. Vitamin C
- C. Calcium
- D. Folic acid
Correct Answer: D
Rationale: The correct answer is D: Folic acid. Folic acid is essential for preventing neural tube defects because it plays a crucial role in DNA synthesis and cell division, particularly during early fetal development. Adequate folic acid intake before and during pregnancy can significantly reduce the risk of neural tube defects. Iron (A), Vitamin C (B), and Calcium (C) are important nutrients for overall health but do not have a direct role in preventing neural tube defects. Iron is vital for red blood cell production, Vitamin C is an antioxidant that supports the immune system, and Calcium is essential for bone health. However, for preventing neural tube defects specifically, folic acid is the essential nutrient.
What is the recommended duration of exclusive breastfeeding?
- A. 3 months
- B. 6 months
- C. 9 months
- D. 12 months
Correct Answer: B
Rationale: The recommended duration of exclusive breastfeeding is 6 months. This is because breast milk provides all the necessary nutrients for an infant's growth and development in the first 6 months of life. Introducing solid foods too early can increase the risk of infections and allergies. Choice A (3 months) is not ideal as it may not provide sufficient nutrients for the baby's growth. Choices C (9 months) and D (12 months) exceed the recommended duration and may not be necessary for exclusive breastfeeding, as other foods can be introduced after 6 months.
Which nutrient is known to reduce the risk of neural tube defects when taken by pregnant women?
- A. Vitamin C
- B. Vitamin D
- C. Folic acid
- D. Iron
Correct Answer: C
Rationale: The correct answer is C: Folic acid. Folic acid is essential for fetal development, especially in preventing neural tube defects. It aids in the formation of the neural tube, which develops into the baby's brain and spinal cord. Pregnant women are advised to take folic acid supplements to reduce the risk of these defects.
Rationale for other choices:
A: Vitamin C - While important for overall health, Vitamin C does not specifically reduce the risk of neural tube defects.
B: Vitamin D - Important for bone health, but not directly linked to reducing neural tube defects.
D: Iron - Necessary for preventing anemia during pregnancy, but not specifically known to reduce the risk of neural tube defects.
What is the appropriate action to take if a child is found to have a fever on the day of immunization?
- A. Administer the vaccine as scheduled
- B. Delay the immunization until the fever subsides
- C. Give a lower dose of the vaccine
- D. Administer an antipyretic before the vaccine
Correct Answer: B
Rationale: The correct action is to delay the immunization until the fever subsides. This is because administering a vaccine during a fever may affect the body's immune response and efficacy of the vaccine. Giving a lower dose (choice C) may not provide adequate protection. Administering an antipyretic (choice D) may temporarily reduce fever but does not address the underlying illness causing the fever. Administering the vaccine as scheduled (choice A) can be harmful and is not recommended when the child has a fever.
