Correct Answer: C

Rationale: The correct answer is to administer pain medication 45 minutes before changing the client's dressing. This intervention is the priority action because the client is experiencing pain during the dressing change. Providing pain relief beforehand can help minimize the discomfort and improve the overall experience for the client. Encouraging relaxation techniques (choice A) or educating about dressing change importance (choice B) are valuable but addressing pain is the priority. Assisting the client to a comfortable position (choice D) is essential for the procedure but does not directly address the client's pain.

Correct Answer: D

Rationale: In a situation where a visitor arrives on the unit with a gun, it is essential to prioritize the safety of patients and staff. Immediately notifying security with all the relevant details is the correct course of action. Asking the visitor to leave or engaging them could escalate the situation and put everyone at risk. Similarly, requesting the gun from the visitor directly is not advisable as it could lead to a dangerous confrontation. By alerting security promptly, you enable trained professionals to handle the situation safely and effectively, minimizing risks and ensuring the safety of all individuals involved.

Rationale: The correct answer is A, job analysis. Job analysis is the first step in the selection process as it involves gathering information about the duties, responsibilities, necessary skills, outcomes, and work environment of a particular job. This information is crucial in creating an accurate job description and specification that will guide the recruitment and selection process. Choices B, C, and D are incorrect because while selection techniques, methods of recruiting, and legal requirements are important aspects of the selection process, they come after the job analysis has been completed.

Correct Answer: D

Rationale: The correct answer is D: Standardize care processes. Lean methodology in healthcare focuses on standardizing care processes to improve efficiency and reduce waste.

Increasing patient throughput may be a byproduct of implementing Lean principles but is not the primary focus.

Correct Answer: D

Rationale: The correct answer is D, Chaos theory.

Contingency theory (choice A) is based on the idea that there is no one best way to organize and manage a corporation. Closed system theory (choice B) refers to systems that are closed off from the outside environment and do not interact with it. Open system theory (choice C) views organizations as open systems that interact with their external environment.
