Final answer:
The nurse manager should respect the nurse's conscientious objection to participating in an abortion and find an alternative solution, while ensuring the nursing practice's values of compassion and respect for individual beliefs are upheld.
Step-by-step explanation:
When a nurse refuses to assist with an abortion due to personal ethical beliefs, the appropriate action for the nurse manager is to respect the nurse's right to conscientious objection and seek an alternate solution that preserves the rights of both the patient and the nursing staff. In line with care ethics, it is important that the nurse manager understands the nurse's concerns and works collaboratively to find an ethically viable path forward that respects all involved parties. Considering the practice of nursing should incorporate values like compassion, understanding and respect for individual beliefs, the nurse manager should facilitate a supportive environment where such ethical dilemmas can be addressed with sensitivity.
