Parkinson's disease is associated with the loss of which of the following neurotransmitter?
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.
Question 2 of 5
What is a primary objective of public health?
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.
Question 3 of 5
What is the primary focus of public health?
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.
Question 4 of 5
Paralysis of all or part of the trunk, legs, and pelvic organs is referred to as:
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.
Question 5 of 5
Which action is an example of primary prevention in community health?
Correct Answer: A
Rationale: Primary prevention aims to prevent the occurrence of a disease before it occurs. Administering immunizations is a direct way to prevent the onset of infectious diseases, making it a clear example of primary prevention. Immunizations boost immunity and reduce the risk of contracting specific diseases. Providing treatment for diseases (choice
B) occurs after the disease has already developed, making it a secondary prevention strategy. Educating about healthy lifestyles (choice
C) and conducting health screenings (choice
D) are important but fall under health promotion and early detection (secondary prevention) rather than primary prevention.
