To develop an effective staffing budget, the nurse manager should:

A. While it's possible that a worsening health state could contribute to non-adherence, it's unlikely to be the sole factor, especially given that the patient has been explained the medication regimen multiple times.
B. While motivation is important for adherence, it's also unlikely to be the sole factor. Many patients with chronic conditions experience challenges with motivation, but effective education and support can help address this.

C. This is the most likely explanation for the patient's repeated non-adherence to the medication regimen. Health literacy refers to an individual's ability to understand and use health information to make informed decisions.
D. This is a possibility, but it's important to rule out other factors first. Cognitive impairment would likely manifest in other areas of the patient's life as well, and it's important to conduct a thorough assessment to determine if this is the case.

A. Horizontal violence, also known as lateral violence, refers to aggressive or disruptive behavior between colleagues at the same level, such as between nurses. Since the head nurse is in a superior position and the staff nurse is a subordinate, the behavior described does not fit the definition of horizontal violence.
B. Bullying involves repeated, intentional actions that undermine or belittle another person. The head nurse’s comments about the staff nurse’s credibility to other staff members could be considered a form of bullying, especially if this behavior is persistent and aims to undermine the staff nurse’s professional reputation or confidence.
C. Confrontation is a direct approach to addressing disagreements or conflicts between individuals. It involves discussing differing views openly and is intended to resolve issues through dialogue. In this
case, the head nurse’s behavior does not involve direct confrontation with the staff nurse about the disagreement but rather involves undermining the staff nurse's credibility behind their back.
D. Mediation is a process where a neutral third party helps facilitate communication and negotiation between conflicting parties to reach a resolution. The behavior described does not involve mediation; instead, it involves negative comments and undermining behavior without seeking resolution or involving a mediator.
