Correct Answer: A

Rationale: The correct answer is A: address the letter to "To Whom It May Concern." This is the appropriate procedure when the applicant is unsure of the recipient's name and title. It is a professional and formal way to address a cover letter when the specific recipient is unknown. Option B is incorrect as addressing the letter to a generic title like "Nurse Recruiter" may not be appropriate if the recipient does not hold that specific title. Option C may be time-consuming and unnecessary if the applicant can use a more general salutation. Option D is incorrect because leaving the salutation blank can come across as unprofessional and lazy.

Correct Answer: C

Rationale: The correct answer is C: Continual supervision is being provided until the RN determines competency. Rationale: 1. Continual supervision is necessary for the LPN/LVN on the first day to assess their competency. 2. The RN checks frequently throughout the shift to provide support and evaluate the LPN/LVN's performance. 3. Competency must be determined before reducing supervision levels. 4. This level of supervision ensures patient safety and quality care. Incorrect choices: A: There is no supervision - Incorrect because supervision is provided by the RN. B: Periodic inspection - Incorrect as continual supervision is needed for competency assessment. D: Initial supervision - Incorrect as supervision should continue until competency is established. In summary, choice C is correct as continual supervision is crucial for the LPN/LVN on their first day to ensure patient safety and quality care.

Correct Answer: B

Rationale: The correct answer is B: Clinical consultant. In this scenario, the DON is providing guidance and expertise to the ad hoc committee in developing strategies to meet the organization's goal of providing quality patient care. As a clinical consultant, the DON utilizes their clinical knowledge and experience to coach and support the committee in achieving desired outcomes related to patient care. The other choices are incorrect because: A: Transactional leadership focuses on exchanging rewards for performance and does not align with the DON's role in providing clinical guidance. C: Corporate supporter role involves advocating for organizational goals at a higher level and is not directly related to coaching a committee on clinical matters. D: Autocratic leadership style is characterized by making decisions without input from others, which is not demonstrated in the scenario where the DON is coaching and guiding the committee.

Step 3: A acknowledges the mistake, B deflects by attacking the supervisor, and C blames the IV setup. In summary, D is incorrect as it diverts attention from the main issue, making it a red herring.
