A nurse is caring for a client who is starting treatment for substance use disorder. Which of the following actions indicates the nurse is practicing the ethical principle of nonmaleficence?

A. Withholding a prescribed medication that is causing adverse effects for the client
The principle of nonmaleficence, often summarized as "do no harm," emphasizes the nurse's duty to prevent harm and to remove existing harm. If a medication prescribed to a client is causing adverse effects, the nurse should withhold the medication to prevent harm to the client.

B. Educating the client about legal rights concerning treatment
Educating the client about their legal rights falls under providing information and ensuring the client's autonomy but does not directly address the principle of non-maleficence.

C. Providing the client with quality care regardless of ability to pay for treatment
Providing quality care regardless of the client's ability to pay is an ethical practice, but it aligns more with the principles of justice and beneficence rather than nonmaleficence.

D. Being truthful with the client about the manifestations of withdrawal
Being truthful and providing accurate information to the client about withdrawal symptoms is crucial, but it doesn't directly address the principle of nonmaleficence.

A. "I will learn how to voluntarily control my blood pressure and heart rate."
This statement indicates the client might be referring to techniques such as biofeedback or relaxation exercises that involve controlling physiological responses consciously. While these are relaxation techniques, they are not specifically cognitive reframing. Cognitive reframing focuses on changing negative thought patterns.

B. "I will practice replacing negative thoughts with positive self-statements."
This statement accurately reflects the concept of cognitive reframing. It involves identifying negative or unhelpful thoughts and consciously replacing them with positive, empowering, or rational thoughts. This technique is widely used in cognitive-behavioral therapy (CBT) to help individuals manage stress, anxiety, and various mental health issues.

C. "I will focus on a mental image while concentrating on my breathing."
This statement describes a relaxation technique where individuals visualize a calming image and synchronize their breathing with this mental image. While this practice is beneficial for relaxation, it is not cognitive reframing. Cognitive reframing specifically deals with changing the content of thoughts, not necessarily focusing on mental imagery.

D. "I will progressively relax each of my muscle groups when feeling stressed."
This statement describes a relaxation technique known as progressive muscle relaxation. It involves tensing and then relaxing different muscle groups to reduce physical tension and stress. While this technique is excellent for relaxation, it is not cognitive reframing. Cognitive reframing pertains to changing thoughts, not physical sensations.
