18. If a person displays an overt sign of a disease, what kind of sign is this person showing?

Answer: D

Explanation:

The person is showing an easily observed sign of the disease.

An overt sign of a disease is one that is readily apparent and can be easily observed by others. This indicates that the sign is clear and evident, making it classified as easily observed.

A) Interpretative

Interpretative signs refer to those that require analysis or judgment to understand, rather than being directly observable. Therefore, this option is incorrect because an overt sign is not interpretative; it is clear and straightforward.

B) Somewhat hidden

Somewhat hidden signs imply that the signs are not fully visible or require probing to uncover. This contradicts the definition of overt signs, which are by nature obvious and manifest, making this option incorrect.

C) Verbal

Verbal signs pertain to communicated symptoms through speech or language rather than physical manifestations. Since overt signs are visible and not limited to verbal communication, this option is not applicable and therefore incorrect.

D) Easily observed

Easily observed signs are those that are apparent and can be noticed without extensive examination. This aligns perfectly with the concept of overt signs, confirming that this option is correct.

Conclusion

The correct answer is "easily observed" because it directly describes the nature of overt signs, which are visible and clear indicators of a disease. All other options fail to capture this definition accurately, as they either imply ambiguity or rely on non-visual cues.
