What is the primary focus of public health?
- A. Preventing disease and promoting health
- B. Providing health education
- C. Ensuring access to health care services
- D. Reducing health disparities
Correct Answer: A
Rationale: The primary focus of public health is preventing disease and promoting health. This is because public health aims to improve the overall health of populations through preventive measures such as vaccinations, health education, and policy interventions. By focusing on prevention, public health addresses the root causes of health issues and promotes well-being on a larger scale. Providing health education (choice B) is a component of public health but not the primary focus. Ensuring access to health care services (choice C) is important but falls under healthcare delivery rather than public health. Reducing health disparities (choice D) is a goal of public health but not the primary focus, as it is a part of the broader mission to promote health equity.

- A. Providing direct patient care
- B. Advocating for patients' health needs
- C. Educating about health promotion
- D. Managing chronic conditions
Correct Answer: B
Rationale: The correct answer is B: Advocating for patients' health needs. Nurses in community health must advocate for their patients to ensure they receive proper care and resources.

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 the drug of choice for progressive multiple sclerosis?
- A. Ocrelizumab
- B. Dimethyl fumarate
- C. Teriflunomide
- D. Fluoroquinolones
Correct Answer: A
Rationale: The correct answer is A: Ocrelizumab. It is the drug of choice for progressive multiple sclerosis due to its proven efficacy in reducing disease progression and disability in clinical trials. Ocrelizumab specifically targets B cells, which play a key role in the pathogenesis of multiple sclerosis. Dimethyl fumarate (B) and Teriflunomide (C) are more commonly used for relapsing-remitting multiple sclerosis rather than progressive forms. Fluoroquinolones (D) are antibiotics and have no role in the treatment of multiple sclerosis.
Paralysis of all or part of the trunk, legs, and pelvic organs is referred to as:
- A. Hemiplegia
- B. Tetraplegia
- C. Paraplegia
- D. Hemiparesis
Correct Answer: C
Rationale: The correct answer is C: Paraplegia. Paraplegia refers to the paralysis of the lower half of the body, including both legs and often the trunk and pelvic organs. This term specifically indicates paralysis below the waist. Hemiplegia (A) refers to paralysis on one side of the body, not the trunk and legs. Tetraplegia (B) is paralysis of all four limbs and the trunk, not specifically the trunk, legs, and pelvic organs. Hemiparesis (D) is weakness on one side of the body, not a complete paralysis of the trunk, legs, and pelvic organs.

Genetic predisposition (A) refers to inherited traits, not external factors. Personal health behaviors (B) are individual choices. Biological factors (C) focus on physical attributes, not societal influences. Economic stability (D) aligns with social determinants by addressing social, economic, and environmental factors that shape health outcomes.
