The student nurse is collecting data on a child diagnosed with cystic fibrosis and notes the child has a barrel chest and clubbing of the fingers. In explaining this manifestation of the disease, the staff nurse explains the cause of this symptom to be:

high sodium chloride concentration in the sweat.

chronic lack of oxygen.

decreased respiratory capacity.

impaired digestive activity.

Answer and Explanation

The Correct Answer is B

A. While cystic fibrosis is characterized by a high concentration of sodium chloride in sweat due to defective chloride channels, this is not the cause of the barrel chest and clubbing of the fingers.

B. The barrel chest and clubbing of the fingers are often seen in children with cystic fibrosis due to chronic hypoxia (lack of oxygen). Chronic lung infections, airway obstruction, and respiratory insufficiency associated with cystic fibrosis lead to prolonged low oxygen levels, which can result in these physical changes.

C. Decreased respiratory capacity, often due to the chronic respiratory issues associated with cystic fibrosis, can result in a barrel chest (increased chest diameter due to air trapping) and clubbing of the fingers (a sign of chronic hypoxia).

D. Decreased respiratory capacity (due to thick mucus and airway obstruction) does contribute to chronic respiratory issues in cystic fibrosis, but the direct cause of the barrel chest and clubbing is the chronic lack of oxygen (hypoxia) rather than decreased capacity alone. The changes in the chest and fingers are a result of prolonged oxygen deprivation.

Correct Answer is B

Explanation

A. The deciduous teeth falling out:

The falling out of deciduous (baby) teeth is a natural part of early childhood development and is not specifically indicative of adolescence. The loss of deciduous teeth usually occurs before the age of 12.

B. The beginning of puberty:

Puberty is the period of physical and sexual development that marks the transition from childhood to adolescence. It involves the development of secondary sexual characteristics, such as breast development in girls and facial hair growth in boys, along with other physical changes.

C. The child becoming self-supported:

Becoming self-supported is a broad concept that can occur at various stages of development and is not a specific marker of the beginning of adolescence. Adolescents may gain increasing independence, but this is a gradual process.

D. The fine motor skills fully developed:

Fine motor skills typically develop during early childhood, and the full development of these skills is not a specific marker for the beginning of adolescence. Fine motor skills involve the coordination of small muscle movements and are important for tasks like writing and drawing.

A. Internet resources, movies, and television have the most accurate and current information for your adolescent to learn about sexuality issues. B. Being honest and straightforward with teenagers will encourage them to ask about subjects like sexuality. C. Most schools have excellent programs to teach adolescents about sex and sexuality. D. Teenagers spend so much time with their peers, and that is usually how they find out about sex.

Correct Answer is B

Explanation

A. Internet resources, movies, and television have the most accurate and current information for your adolescent to learn about sexuality issues:

This statement may not be accurate, as the internet, movies, and television can sometimes provide misinformation or biased perspectives. It's crucial to emphasize the importance of reliable and evidence-based sources when adolescents seek information about sexuality.

B. Being honest and straightforward with teenagers will encourage them to ask about subjects like sexuality:

This statement is valuable as it emphasizes open communication. Being honest and straightforward creates an environment where adolescents feel comfortable approaching their caregivers with questions or concerns about sexuality. It promotes trust and a supportive relationship.

C. Most schools have excellent programs to teach adolescents about sex and sexuality:

While some schools do have comprehensive sex education programs, the quality of these programs can vary. Additionally, the involvement of parents and caregivers in discussions about sex and sexuality is essential. Relying solely on school programs may not cover all aspects, and caregivers play a crucial role in reinforcing positive attitudes and values.

D. Teenagers spend so much time with their peers, and that is usually how they find out about sex:

While it's true that peers can influence adolescents, relying solely on peer influence for information about sex may not provide accurate or comprehensive knowledge. Caregivers should aim to create an open and honest dialogue to supplement information from peers and address any misconceptions.
