Health education materials should be written at no greater than:

A. Crowding each slide with a lot of information. Crowding slides with too much information makes it difficult for the audience to absorb key points and can lead to confusion.

B. Each slide should have its own heading. Having a clear heading on each slide helps to organize information and guide the audience's understanding of the content.

C. Using low-resolution images. Low-resolution images can appear blurry or pixelated, which detracts from the professionalism and clarity of the presentation.

D. Select colors that have low contrast. Low contrast colors can make text and images hard to read, while high contrast enhances visibility and comprehension.

A. Maintaining financial records and identifying budget deficits.
This option relates to financial management rather than informatics competencies. Informatics primarily focuses on the use of information technology in healthcare settings, not financial aspects.

B. Integrating and applying information, computer, and nursing sciences.
This is a key informatics competency, as it involves the ability to integrate knowledge from various fields to improve patient care.

C. Possessing basic information management and computer technology skills.
This is essential for nurses to effectively utilize electronic health records (EHR) and other health technologies, making it a valid informatics competency.

D. Using information management and computer technology. This is a fundamental competency in informatics, as it directly relates to the effective use of technology to manage patient data and improve care.
