A nurse wants to conduct an Internet search because a patient is experiencing vital-sign fluctuations.Which statement about this source of clinical data is correct?
The same search terms should be used repeatedly to produce consistent results.
Important key words should be used to narrow and direct the search.
Extraneous terms are used to make the search more diverse.
Words are placed within parentheses to limit the search results.
The Correct Answer is B
A. The same search terms should be used repeatedly to produce consistent results – This may limit the scope of information and won’t necessarily improve result accuracy.
B. Important keywords should be used to narrow and direct the search – Using specific keywords effectively narrows the search, allowing the user to find relevant information faster.
C. Extraneous terms are used to make the search more diverse – Adding unrelated terms can yield irrelevant results and confuse the search.
D. Words are placed within parentheses to limit the search results – Parentheses are not generally used in search engines to narrow results; quotes are more effective in limiting to exact phrases.

Correct Answer is B
Explanation
A. The clinic should require all employees to download antivirus software onto their work computers. – Antivirus software helps with malware but doesn’t secure weak or easily guessed passwords.
B. Daniel should have used a more complex password that includes a combination of numbers, letters, and symbols. – A more complex password not related to personal information would be harder to guess, reducing the risk of unauthorized access.
C. Daniel should have kept his password in a private location only he can access. – This is good practice for security, but it doesn’t address the need for a complex password.
D. The clinic should require all employees to change their password frequently. – Changing passwords regularly helps overall security but does not directly address the problem of easy-to-guess passwords based on personal information.
Correct Answer is D
Explanation
A. Security testing – Security testing assesses protection mechanisms but does not address user interface or usability issues.
B. System testing – System testing evaluates overall functionality but does not specifically focus on user experience or ease of navigation.
C. Load testing – Load testing assesses system performance under high traffic, which is unrelated to interface usability.
D. Usability testing – Usability testing identifies issues related to ease of use, navigation, and visual ergonomics, making it the ideal test to address challenges like too many clicks and difficult-to-read screens.
