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.

Which of the following is an example of a social determinant of health?
- A. Genetic predisposition
- B. Personal health behaviors
- C. Biological factors
- D. Economic stability
Correct Answer: D
Rationale: The correct answer is D, Economic stability, as it directly influences access to healthcare, housing, education, and nutritious food, impacting overall health. 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.
What is the term for creating a surgical airway in the front of the neck (cervical region) to remove copious secretions?
- A. Bronchoscopy
- B. Tracheostomy
- C. Thoracentesis
- D. Underwater seal drainage
Correct Answer: B
Rationale: The correct answer is B: Tracheostomy. Tracheostomy involves creating a surgical airway in the front of the neck to remove copious secretions. This procedure allows direct access to the trachea to facilitate breathing and clear secretions. Bronchoscopy (choice A) involves visualizing the airways with a scope, not creating a surgical airway. Thoracentesis (choice C) is a procedure to remove fluid from the chest cavity, not the airway. Underwater seal drainage (choice D) is used for managing chest tube drainage, not creating a surgical airway.
Parkinson's disease is associated with the loss of which of the following neurotransmitter?
- A. Serotonin
- B. Adrenaline
- C. Dopamine
- D. GABA
Correct Answer: C
Rationale: The correct answer is C: Dopamine. Parkinson's disease is primarily caused by the loss of dopamine-producing neurons in the brain. Dopamine is crucial for controlling movement, mood, and cognition. Serotonin (A) is not directly related to Parkinson's. Adrenaline (B) is involved in the fight-or-flight response, not Parkinson's. GABA (D) is an inhibitory neurotransmitter, not typically associated with Parkinson's disease.
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 most crucial factor in determining the health of a community?
- A. Access to health care services
- B. Socioeconomic status
- C. Environmental quality
- D. Genetic predisposition
Correct Answer: B
Rationale: The correct answer is B: Socioeconomic status. Socioeconomic status influences access to healthcare, environmental quality, and genetic predisposition. Low socioeconomic status is linked to poorer health outcomes due to limited access to healthcare services, exposure to environmental hazards, and unhealthy lifestyle factors. It also impacts education, employment, and social support, all of which are crucial for community health. Access to healthcare services (A) is important but is influenced by socioeconomic status. Environmental quality (C) and genetic predisposition (D) play a role, but socioeconomic status has a broader impact on overall community health.
