A nurse is caring for a client who has a prescription for chlorpromazine. Which of the following findings should the nurse identify as an indication that the medication is effective?

- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.

- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.

- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.

- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

• The correct answer is Choice A.

  Choice A rationale: Forming a committee of staff members to investigate current staffing issues is the first step the nurse manager should take. This is because it is important to understand the root cause of the problem before implementing any changes. By forming a committee, the nurse manager can gather different perspectives and insights from the staff members who are directly affected by the staffing issues. This will help in identifying the specific problems and coming up with effective solutions. Furthermore, involving the staff in the decision-making process can increase their acceptance of the changes and reduce resistance.

  Choice B rationale: Providing support to staff members who are resistant to staffing changes is an important step, but it should not be the first action. Before providing support, the nurse manager needs to understand the specific issues causing the resistance. This can be achieved by forming a committee of staff members to investigate the staffing issues.

  Choice C rationale: Scheduling a staff meeting to present the different options to staff members is a crucial step in the process. However, this should be done after the nurse manager has a clear understanding of the staffing issues and has identified potential solutions. Presenting options without first understanding the problem may lead to ineffective solutions and increased resistance from staff members.

  Choice D rationale: Giving the staff members advance written notice of staffing changes is a necessary step to ensure transparency and to give staff members time to adjust. However, this should be done after the nurse manager has identified the staffing issues, explored potential solutions, and decided on the changes to be implemented.
