ATI Community Health Nursing Ch 7

Correct Answer: B

Rationale: Socioeconomic status plays a vital role in determining the health of a community. It affects access to resources, education, employment opportunities, housing, and healthcare services. Individuals with higher socioeconomic status generally have better health outcomes due to their ability to afford healthier lifestyle choices, quality healthcare, and living environments. In contrast, individuals with lower socioeconomic status may face barriers to accessing essential healthcare services, nutritious food, safe housing, and education, leading to poorer health outcomes. Therefore, addressing socioeconomic disparities is crucial in promoting community health and well-being.

Correct Answer: C

Rationale: Parkinson's disease is a neurodegenerative disorder characterized by the loss of dopamine-producing neurons in the brain. Dopamine is a neurotransmitter responsible for coordinating smooth muscle movements. The decrease in dopamine levels leads to the motor symptoms associated with Parkinson's disease, such as tremors, rigidity, and bradykinesia. Serotonin, adrenaline, and GABA are not primarily implicated in the pathophysiology of Parkinson's disease.

Correct Answer: A

Rationale: Grouping and crossmatching is the procedure performed prior to a blood transfusion to determine the blood type and identify any potential incompatibilities between the donor and recipient. This process involves testing the recipient's blood for ABO and Rh antigens and crossmatching it with the donor's blood to ensure compatibility and prevent adverse reactions during the transfusion. Complete blood count, D-dimer test, and blood clotting test are other laboratory tests that serve different purposes and are not specifically done to detect incompatibilities prior to blood transfusion.

Correct Answer: B

Rationale: Tracheostomy is the process of surgically creating an airway in the front of the neck to aid in breathing or remove secretions from the airway. Bronchoscopy involves visualizing the airways using a scope, not creating an airway. Thoracentesis is the procedure to remove fluid or air from the pleural space around the lungs, not related to creating an airway. Underwater seal drainage is a method used in chest drainage systems to remove air or fluid from the pleural space, not the creation of an airway.

Correct Answer: A

Rationale: Access to health care is a critical factor closely linked to health disparities. Limited access to healthcare services can result in disparities in health outcomes, as individuals with restricted access may face challenges in receiving timely and adequate medical care, leading to poorer health outcomes compared to those with better access.
