Correct answer:

Family stress theory explains the reaction of families to stressful events. In addition, the theory helps suggest factors that promote adaptation to the stress. Stressors, both positive and negative, are cumulative and affect the family. Adaptation requires a change in family structure or interaction. Interactional theory is not a family theory. Interactions are the basis of general systems theory. Eriksons theory applies to individual growth and development, not families. Developmental systems theory is an outgrowth of Duvalls theory. The family is described as a small group, a semiclosed system of personalities that interact with the larger cultural system. Changes do not occur in one part of the family without changes in others.

Correct answer:

Caput succedaneum is defined as a vaguely outlined area of edematous tissue situated over the portion of the scalp that presents in a vertex delivery. The swelling consists of serum or blood (or both) accumulated in the tissues above the bone, and it may extend beyond the bone margin. Hydrocephalus is caused by an imbalance in production and absorption of cerebrospinal fluid. When production exceeds absorption, fluid accumulates within the ventricular system, causing dilation of the ventricles. A cephalhematoma has sharply demarcated boundaries that do not extend beyond the limits of the (bone) suture line. A subdural hematoma is located between the dura and the cerebrum. It should not be visible on the scalp.

Correct answer:

Ethnocentrism is the belief that ones way of living and behaving is the best way. This includes the emotional attitude that the values, beliefs, and perceptions of ones ethnic group are superior to those of others. Acculturation is the gradual changes that are produced in a culture by the influence of another culture that cause one or both cultures to become more similar. The minority culture is forced to learn the majority culture to survive. Cultural shock is the helpless feeling and state of disorientation felt by an outsider attempting to adapt to a different culture group. Cultural sensitivity, a component of culturally competent care, is an awareness of cultural similarities and differences.

Correct answer:

Status is culturally determined and varies according to each culture. Some cultures ascribe higher status to age or socioeconomic position. Social roles also are influenced by the culture. Ethnicity is an affiliation of a set of persons who share a unique cultural, social, and linguistic heritage. It is one component of culture. Race and culture are two distinct attributes. Whereas racial grouping describes transmissible traits, culture is determined by the pattern of assumptions, beliefs, and practices that unconsciously frames or guides the outlook and decisions of a group of people. Cultural development may be limited by geographic boundaries, but the boundaries are not culturally determined.

Correct answer:

The benefits of prenatal diagnostic testing extend beyond decisions concerning abortion. If the child has congenital disorders, decisions can be made about fetal surgery if indicated. In addition, if the child is expected to require neonatal intensive care at birth, the mother is encouraged to deliver at a level III neonatal center. The couple is counseled about the advantages and disadvantages of prenatal diagnosis, not pregnancy termination, although the family cannot be forced to have prenatal testing. The information gives the parents time to grieve and plan for their child if congenital disorders are present. If the child is free of defects, then the parents are relieved of a major worry.

Correct answer:

Permissive parents avoid imposing their own standards of conduct and allow their children to regulate their own activity as much as possible. The parents exert little or no control over their childrens actions. Dictatorial or authoritarian parents attempt to control their childrens behavior and attitudes through unquestioned mandates. They establish rules and regulations or standards of conduct that they expect to be followed rigidly and unquestioningly. Democratic parents combine permissive and dictatorial styles. They direct their childrens behavior and attitudes by emphasizing the reasons for rules and negatively reinforcing deviations. They respect their childrens individual natures.

Correct answer:

Boys have a preponderance for injuries over girls because of a difference in behavioral characteristics, a high activity temperament is associated with risk-taking behaviors, and stress predisposes children to increased risk taking and self-destructive behaviors. Therefore, a male child with a high activity level and living in a stressful environment has the highest number of risk factors. A girl with several siblings and a stable home life is low risk. A boy with previous injuries has two risk factors, but an even temper is not a risk factor for injuries. A girl who reacts negatively to new situations but has no previous serious illnesses has only one risk factor.

Correct answer:

Signs and symptoms are the cues and clusters of defining characteristics that are derived from a patient assessment and indicate actual health problems. The first part of the nursing diagnosis is the problem statement, also known as the human response to the state of illness or health. The identification of actual health problems may be part of the medical diagnosis. The nursing diagnosis is based on the human response to these problems. The human response is therefore a component of the nursing diagnostic statement. Potential risk factors are used to identify nursing care needs to avoid the development of an actual health problem when a potential one exists.

Correct answer:

Brown fat is a unique source of heat for newborns. It has a larger content of mitochondrial cytochromes and a greater capacity for heat production through intensified metabolic activity than does ordinary adipose tissue. Heat generated in brown fat is distributed to other parts of the body by the blood. It is effective only in heat production. Brown fat is located in superficial areas such as between the scapulae, around the neck, in the axillae, and behind the sternum. These areas should not protect the newborn from injury during the birth process. The newborn has a thin layer of subcutaneous fat, which does not provide for conservation of heat.

Correct answer:

Translocation is the transfer of all or part of a chromosome to a different chromosome after chromosome breakage. It can be balanced, producing no phenotypic effects, or unbalanced, producing severe or lethal effects. Trisomy is an abnormal number of chromosomes caused by the presence of an extra chromosome, which is added to a given chromosome pair and results in a total of 47 chromosomes per cell. Monosomy is an abnormal number of chromosomes whereby the chromosome is represented by a single copy in a somatic cell. Nondisjunction is the failure of homologous chromosomes or chromatids to separate during mitosis or meiosis.
