A nurse is caring for a client who is scheduled for coronary artery bypass surgery and does not wish to have any blood transfusions. The nurse should recognize that administering blood to this client is a violation of which of the following ethical principles?

The correct answer is: B.

Choice A reason:

Suctioning a client's long-term tracheostomy is a complex procedure that involves sterile technique and assessment skills that are beyond the scope of assistive personnel's practice. It requires clinical judgment and the ability to respond to complications, which are responsibilities typically reserved for licensed nursing staff.

Choice B reason:

Using a pain rating scale to monitor a client's pain level is a task that can be delegated to assistive personnel. It involves asking the client to rate their pain on a scale, which does not require clinical judgment or advanced skills. The assistive personnel can then report the pain level to the nurse, who will make decisions regarding pain management.

Choice C reason:

Performing a dressing change on a client's peripherally inserted central catheter (PICC) is not within the scope of assistive personnel. This task requires aseptic technique and knowledge of PICC line management to prevent infection and other complications, which are typically the responsibility of the registered nurse or licensed practical nurse.

Choice D reason:

Instructing a client on self-administration of a tap water enema involves teaching and assessment to ensure the client understands and can perform the procedure safely. This is a task that requires licensed nursing knowledge and skills to educate the client and evaluate their competency.

Choice A reason: This is the correct choice because autonomy is the ethical principle that respects the client's right to make their own decisions about their health care. The nurse should honor the client's wishes and preferences, even if they differ from the nurse's or the provider's. The nurse should not force or coerce the client to accept blood transfusions, as this would violate their autonomy.

Choice B reason: This is not the correct choice because fidelity is the ethical principle that requires the nurse to be faithful and loyal to the client and their agreement. The nurse should keep their promises and commitments, and act in the best interest of the client. The nurse should not administer blood transfusions to the client without their consent, as this would breach their trust and fidelity.

Choice C reason: This is not the correct choice because justice is the ethical principle that ensures fair and equal treatment for all clients. The nurse should distribute resources and services according to the client's needs and rights, and avoid any discrimination or bias. The nurse should not administer blood transfusions to the client against their will, as this would disregard their justice.

Choice D reason: This is not the correct choice because veracity is the ethical principle that obliges the nurse to be honest and truthful with the client. The nurse should provide accurate and complete information, and disclose any errors or risks. The nurse should not administer blood transfusions to the client without informing them, as this would violate their veracity.
