Correct Answer: D

Rationale: The correct answer is D because asking about the number of children the candidate has could potentially lead to discrimination based on family responsibilities, which is illegal. This question is not related to the candidate's ability to perform the job duties in the operating room. A: Asking about criminal convictions is legal for certain positions for safety reasons. B: Mentioning pre-employment checks is standard practice and not illegal. C: Inquiring about weaknesses is a common interview question and not discriminatory.

Correct Answer: B

Rationale: The correct answer is B: Pareto chart. A Pareto chart is a quality improvement tool used to prioritize and focus efforts on the most significant causes of a problem. In this case, the hospital used the chart to identify the main causes of medication errors, helping them to allocate resources efficiently. The Pareto principle states that roughly 80% of effects come from 20% of causes, making it a powerful tool for process improvement. A: Run chart is used to track data over time but does not prioritize causes like a Pareto chart. C: Flowcharts are used to map out processes and are helpful for understanding the sequence of activities, not for prioritizing causes. D: Cause-and-effect diagrams (Fishbone or Ishikawa diagram) are used to identify and organize potential causes of a problem but do not prioritize them like a Pareto chart. In summary, the Pareto chart is the most appropriate tool in this situation because it helps focus efforts on the most significant causes

Correct Answer: B

Rationale: The correct answer is B: Method. In the scientific process, the method refers to designing and planning the research study. In this scenario, the group of nurses is planning how to improve teaching effectiveness for patients with hearing impairment, which involves designing the study by using a Likert scale pre-post teaching evaluation, conducting a hearing test, and involving social work for evaluation. This step focuses on determining how the research will be carried out, including data collection methods and procedures. The other choices are incorrect because: A: Hypothesis - This step involves formulating a testable prediction based on observations or existing knowledge. C: Results - This step involves analyzing the data collected and drawing conclusions. D: Evaluation - This step involves assessing the effectiveness or outcomes of the research study.

Correct Answer: D

Rationale: The correct answer is D: Electronic messaging. In today's fast-paced world, electronic messaging, such as emails, text messages, and social media, is the most commonly used means of societal communication due to its immediacy, convenience, and widespread accessibility. It allows people to communicate quickly across long distances and reach a large audience efficiently. Facial expressions (A) are important but limited in reach. Spoken word (B) is also crucial but less prevalent in today's digital age. Written messages (C) are still used but electronic messaging has largely replaced traditional written communication for its speed and efficiency.

Correct Answer: A

Rationale: The correct answer is A because the nurse in matched scrubs with a lab coat and minimal jewelry portrays professionalism and adherence to safety standards. The lab coat signifies a commitment to infection control and respect for the clinical environment. The hair being pulled back ensures cleanliness and prevents hair from falling into a patient's wound. Small stud earrings are safe and do not pose a risk of injury to the nurse or patient. Choice B is incorrect because mismatched scrubs and large hoop earrings may not reflect professionalism or attention to detail, which are crucial in nursing practice. Choice C is incorrect as the nurse in a white uniform with apron and no jewelry may seem traditional but lacks the modern approach and attention to safety standards displayed by choice A. Choice D is incorrect because the nurse with nose and eyebrow piercings, despite wearing a starched white uniform and cap, may not be perceived as a professional and may not adhere to conservative workplace standards.
