**Question:** Community health guide is selected by:

A. Adequate community coverage
B. Cost-effectiveness
C. Availability of resources
D. Ease of implementation

**Core Concept:** In selecting a community health guide, various factors play a role in determining the most appropriate intervention or program. These factors are crucial for ensuring the guide addresses the local community's needs effectively and efficiently.

**Why the Correct Answer is Right:**

Correct Answer: **D. Ease of implementation**

A community health guide should be chosen based on ease of implementation, which refers to the simplicity and practicality of integrating the guide into the existing healthcare infrastructure and working environment. This ensures that the guide can be effectively applied in the community and is sustainable over time. Ease of implementation also includes considering the local healthcare professionals' expertise, training requirements, and resources available in the community.

**Why Each Wrong Option is Incorrect:**

A. **Adequate community coverage (Option A)**: While community coverage is important, focusing solely on this aspect might lead to choosing a guide that is difficult to implement due to logistical challenges or resource constraints. A balance between community coverage and ease of implementation is essential.

B. **Cost-effectiveness (Option B)**: Although cost-effectiveness is important, it should not be the sole criteria for selecting a community health guide. Ease of implementation ensures the guide's practicality and sustainability in the community setting.

C. **Availability of resources (Option C)**: While availability of resources plays a role, focusing solely on them might result in selecting a guide that is not suitable for the community's context and thus difficult to implement. A comprehensive evaluation considering both resources and ease of implementation is crucial.

**Clinical Pearl:** The selection of a community health guide involves a careful balancing act between different factors, including community coverage, cost-effectiveness, resource availability, and ease of implementation. A well-rounded approach ensures the guide is effective, efficient, and sustainable in the community setting.
