Earlier, you learned about the different issues experienced by those affected by a violent crime or homicide. The issues were event recall, fear, grief, loss of control, self-identity, compensation, blame, rage, and meaning of life. For mental health workers, an important part of working with victims of violent crimes like John is being able to understand these psychological issues. Reflecting on the case study, select a poem, song lyric, or picture that you believe accurately represents John’s feelings and emotions. Then write an essay discussing your beliefs.

Answer:

It is not clear exactly how many young people are affected by the death of an immediate family member. Kliman 82 estimates that 5 percent of children in the United States—1.5 million—lose one or both parents by age 15; others suggest that the proportion is substantially higher in lower socioeconomic groups. This chapter discusses the types of bereavements considered to have the most serious implications for medical, psychiatric, and behavioral sequelae in children—namely, death of a parent or sibling. Because more of the literature in this field deals with parental than with sibling loss and because many of the reactions to both types of bereavement overlap, most of the discussion is based on studies of response to the death of a parent.

Explanation:

Individuals continue to grow and develop throughout life, but during no other period beyond childhood and adolescence are specific reactions as likely to be influenced by the level of development. Because the impact of trauma in children depends so heavily on the life stage during which the event occurs, this chapter is informed by a particular emphasis on developmental analysis. This perspective assumes that the repercussions and meanings of major object loss will be colored by the individual child's level of development. Psychiatrists and others have generally been struck by how often major childhood loss seems to result in psychopathology. Studies of adults with various mental disorders, especially depression, frequently reveal childhood bereavement, suggesting that such loss may precipitate or contribute to thedevelopment of a variety of psychiatric disorders and that this experience can render a person emotionally vulnerable for life. This special vulnerability of children is attributed to developmental immaturity and insufficiently developed coping capacities.

development of a variety of psychiatric disorders and that this experience can render a person emotionally vulnerable for life. This special vulnerability of children is attributed to developmental immaturity and insufficiently developed coping capacities.The tendency to impose adult models on children has generally led to a great deal of confusion and misunderstanding about children's grieving. Although sharing some similarities with adults and even with monkeys (see Chapter 7), children's reactions to loss do not look exactly like adults' reactions, either in their specific manifestations or in their duration.

For example, often what seems glib and unemotional in the small child—such as telling every visitor or stranger on the street, "my sister died"—is the child's way of seeking support and observing others to gauge how he or she should feel. Children may be observed playing games in which the death or funeral activities are reenacted in an effort to master the loss. A child may ask the same questions about the death over and over again, not so much for the factual value of the information as for reassurance that the story has not changed. A four- or five-year-old might resume playing following a death as if nothing distressing had happened. Such behavior reflects the cognitive and emotional capacity of the child and does not mean that the death had no impact.

Which of the following is not recommended for promoting good daily bowel habits? 1) Eating plenty of fibrous foods 2) Drinking enough water 3) Exercising regularly 4) Consuming excessive amounts of caffeine

Answers

Answer: 4) Consuming excessive amounts of caffeine

Explanation:

Caffeine contains acids that can harm the intestine.

Final answer:

For good daily bowel habits, it is recommended to consume plenty of water, include fibrous food in your diet, and engage in regular physical exercise. Excessive consumption of caffeine is not recommended as it can lead to dehydration and disrupt the natural digestive process.

Explanation:

Out of the options provided, it's not recommended to promote good daily bowel habits by consuming excessive amounts of caffeine. Drinking plenty of water contributes to softening the stool and preventing constipation by balancing the absorption process. Including plenty of fibrous food in your diet is crucial as fiber adds bulk to the food residue, facilitating easier bowel movements. Lastly, regular physical exercise aids in maintaining a regular bowel movement schedule by strengthening abdominal muscles and promoting healthy digestive activity. Excessive caffeine, on the other hand, can lead to dehydration and disrupt the natural digestive process.
