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. Preventing spread of infection B. Maintaining skin integrity C. Improving nutrition D. Promoting comfort

Correct Answer is A

Explanation

A. Preventing spread of infection:

This is a priority because individuals with acquired immunodeficiency syndrome (AIDS) have a compromised immune system. Preventing the spread of infections is crucial to avoid additional complications and safeguard the individual's health.

B. Maintaining skin integrity:

Skin integrity is important for overall health, but in the context of AIDS, preventing infections and promoting immune function take precedence over maintaining skin integrity. Skin issues might be secondary to the immune system's compromised state.

C. Improving nutrition:

Good nutrition is important for overall health, including supporting the immune system. However, preventing the spread of infection is more immediate and critical in the case of someone with AIDS. Addressing nutritional needs can be part of the overall care plan but might be secondary to preventing infections.

D. Promoting comfort:

While promoting comfort is essential in nursing care, the priority in the case of a child with AIDS would be preventing the spread of infection due to the immunocompromised state. Comfort measures may be incorporated into the care plan, but they would not take precedence over preventing further health complications.
