Sources such as PubMed

B.

Recommended readings from physicians

C.

Comprehensive searches on Google and other search engines

D.

Magazine and newspaper articles

Answer and Explanation

The Correct Answer is A

A. Sources such as PubMed. – PubMed is a database of peer-reviewed medical literature, providing access to high-quality research and systematic reviews, often with high levels of evidence.

 

B. Recommended readings from physicians. – Physician recommendations may vary in quality and are not guaranteed to be based on the highest level of evidence or peer-reviewed sources.

 

C. Comprehensive searches on Google and other search engines. – These searches yield mixed sources of varying quality and do not necessarily prioritize high-level evidence-based research.

 

D. Magazine and newspaper articles. – These are typically not peer-reviewed or scientifically rigorous, often intended for the general public rather than professionals, and may not rely on high levels of evidence.

Correct Answer is B

Explanation

A. The nurse should use a more complex password that includes a combination of numbers, letters, and symbols. – A complex password is generally good security practice but doesn’t help if the password is left in an accessible place.

B. The nurse should keep her password in a private location that only she can access. – Keeping the password in a private, secure location would prevent unauthorized access, ensuring it’s not visible to patients or others.

C. The hospital should ask all employees to change their password frequently. – Regularly updating passwords can help prevent security breaches but doesn’t solve the issue of visible passwords.

D. The hospital should require all employees to download antivirus software onto their work computers. – Antivirus software helps with malware protection but doesn’t prevent unauthorized access due to visible passwords.

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.
