Community Health HESI Study Guide

Correct Answer: D

Rationale: The best approach when teaching a responsible family member a procedure for the patient is to demonstrate the procedure. By demonstrating, the family member can visually see how it is done, making it easier for them to understand and replicate. This hands-on approach is more effective than just describing the procedure (choice C) or arranging for practice (choice B) without a visual demonstration. Performing all the steps (choice A) may not be practical or necessary when the goal is to teach someone else how to do it.

Correct Answer: A

Rationale: The correct answer is A. A patient with known COPD and difficulty breathing after physical exertion like climbing stairs requires immediate assessment by the nurse. This could indicate a potential exacerbation of COPD, which needs prompt intervention to prevent respiratory distress. Choices B, C, and D describe important patient situations that also require attention, but the urgency is higher with a COPD patient experiencing difficulty breathing.

Correct Answer: A

Rationale: Corrected Rationale: Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems. It focuses on identifying and understanding the factors that influence the occurrence and distribution of diseases, defects, disability, or death of groups of individuals. Therefore, the correct answer is A. Choice B, vital health statistics, is not the primary focus of epidemiology. While vital health statistics may be used in epidemiological studies, it is not the direct concern of epidemiology. Choice C, environmental sanitation, although important for public health, is not the main focus of epidemiology. Epidemiology is more concerned with the factors influencing disease occurrence and distribution, rather than environmental sanitation. Choice D, treatment of a communicable disease, is more related to clinical medicine rather than epidemiology. Epidemiology is more focused on prevention, control, and understanding the patterns and causes of diseases rather than their treatment.

Correct Answer: A

Rationale: The correct answer is A: World Health Organization (WHO). The WHO is the primary organization responsible for global public health initiatives, coordinating international health efforts, setting norms and standards, providing technical support, and monitoring health trends. Choices B, C, and D are incorrect because while they play significant roles in health and global affairs, they do not have the primary responsibility for global public health like the WHO does.

Correct Answer: C

Rationale: The correct answer is C: A deficiency of clotting factor VIII. Hemophilia A is characterized by a lack of clotting factor VIII, which is crucial for blood clotting. This deficiency results in prolonged bleeding. Choices A, B, and D are incorrect. There is no association between Hemophilia A and an excess of red blood cells (Choice A) or an excess of white blood cells (Choice B). Additionally, Hemophilia A specifically involves a deficiency of clotting factor VIII, not both factors VIII and IX (Choice D).
