Final answer:
A client's statement that dismisses the connection between suppressed anger and heart disease indicates a need for further teaching. Extensive research, including studies by Haynes et al. and Chang et al., has shown a significant risk of heart disease associated with suppressed anger and hostility.
Step-by-step explanation:
The effect of suppressing anger on the body is significant, particularly concerning cardiovascular health. Research has demonstrated that anger and hostility are risk factors for the development of heart disease. The client's statement indicating a need for further teaching might be one that downplays or dismisses the impact of suppressed anger on health. For example, if the client says, "I don't think holding in my anger has any effect on my heart health," then this would suggest further education is needed given that extensive research, including a notable study by Haynes et al. (1980), has found that suppressed hostility can substantially elevate the risk of heart disease.
Another study led by Chang, Ford, Meoni, Wang, & Klag (2002) found that men who reported higher levels of anger were significantly more likely to have had a heart attack by the age of 55. This underlines the importance of not ignoring feelings of anger but rather finding healthy ways to express and manage them. Methods such as relaxation techniques described by sitting comfortably, being in a quiet environment, repeating a mantra, and focusing on pleasant thoughts can be beneficial in mitigating the impact of anger on cardiovascular health.
