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 mother opens the capsule and some medication spills on the fingers:

Pancreatic enzymes are usually taken intact, and their contents are meant to be sprinkled on soft food, not opened and spilled. This observation suggests a misunderstanding of the proper administration.

B. The child takes a dose before having an afternoon snack.

In cystic fibrosis, pancreatic enzyme replacement therapy is commonly used to help digest and absorb nutrients. The enzymes are typically taken with meals and snacks to aid in the digestion of food.

C. The child chews an enteric form of the medication:

Pancreatic enzymes are usually enteric-coated to protect them from stomach acid, and they are not meant to be chewed. Chewing can reduce their effectiveness. This observation indicates a need for clarification on administration.

D. The father tells the child that diarrhea is expected with this medication:

While gastrointestinal side effects can occur with pancreatic enzyme use, persistent diarrhea may indicate a dosage issue or other problems. It's important to address this with the healthcare provider. The statement suggests a potential misunderstanding or need for clarification.

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 the highest priority goal because individuals with acquired immunodeficiency syndrome (AIDS) have a severely compromised immune system, making them more susceptible to infections. Preventing the spread of infection is crucial not only for the individual's well-being but also to reduce the risk of transmitting the virus to others.

B. Maintaining skin integrity:

Skin integrity is important, but it may not be the highest priority compared to preventing the spread of infection. Skin breakdown can occur in individuals with compromised immune systems, making them more susceptible to infections, but direct measures to prevent infection take precedence.

C. Improving nutrition:

Nutrition is vital for overall health, including immune function. However, in the context of AIDS, preventing the spread of infection is considered a higher priority. Nutritional support is important but may be addressed concurrently with other goals.

D. Promoting comfort:

Comfort is an important aspect of care, but it may not be the highest priority when compared to preventing the spread of infection. Comfort measures can be integrated into the overall care plan, but infection prevention takes precedence due to the immunocompromised state of the individual.
