A nurse is assisting with teaching a class about sources of stress. The nurse should include that which of the following is an example of a physiological stressor?

Choice A reason : Inability to form healthy relationships is not typically associated with fixation at the oral stage of development. Freud's theory suggests that this issue is more related to the Oedipal conflict during the phallic stage, where the individual's interactions with parental figures shape their future relationships.

Choice B reason : Feelings of shame are generally associated with the anal stage of Freud's psychosexual development, where the child's experiences with toilet training can lead to outcomes that manifest as either excessive orderliness or messiness in adulthood, rather than shame, which is not directly linked to the oral stage.

Choice C reason : Bedwetting is not a condition associated with the oral stage of development. It is more related to the anal stage, where issues of control and independence are central, and bedwetting can be a manifestation of conflicts around toilet training.

Choice D reason : Overeating is a classic example of an oral stage fixation. According to Freud, if an individual's needs are not properly met during the oral stage (0–1 years), they may develop habits such as overeating or smoking to satisfy the residual need for oral stimulation.

Choice A reason : Asthma is a chronic condition characterized by respiratory symptoms such as wheezing, shortness of breath, and coughing due to airway inflammation and constriction. While genetic and environmental factors contribute to the development of asthma, there is no direct correlation between advanced maternal age and an increased risk of asthma in offspring. Asthma's etiology is multifactorial and more closely related to family history, exposure to allergens, and respiratory infections during early childhood.

Choice B reason : Spina bifida is a neural tube defect that occurs when the spine and spinal cord don't form properly. It's associated with factors such as folic acid deficiency during early pregnancy, certain medications, diabetes, and obesity. Although advanced maternal age may slightly increase the risk of chromosomal abnormalities, it is not considered a significant risk factor for spina bifida. Adequate intake of folic acid before conception and during early pregnancy is the most effective prevention strategy.

Choice C reason : Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21 (trisomy 21). The risk of conceiving a child with Down syndrome increases with maternal age, particularly after age 35. This is due to the higher likelihood of nondisjunction events during cell division in older eggs, leading to an abnormal number of chromosomes. Advanced maternal age is a well-established risk factor for Down syndrome, and prenatal screening is recommended to assess the risk.

Choice D reason : Facial malformations, such as cleft lip or palate, are congenital anomalies that can affect the appearance and function of a child's face. These conditions are influenced by genetic and environmental factors, including certain medications, nutritional deficiencies, and exposure to harmful substances during pregnancy. While advanced maternal age may contribute to an increased risk of chromosomal abnormalities, it is not specifically linked to an increased risk of isolated facial malformations.
