A nursing is planning the care of a patient with emphysema who will soon be discharged. What teaching should the nurse prioritize in the plan of care?
- A. Taking prophylactic antibiotics as ordered
- B. Adhering to the treatment regimen in order to cure the disease
- C. Avoiding airplanes, buses, and other crowded public places
- D. Setting realistic short-term and long-range goals
Correct Answer: D
Rationale: A major area of teaching involves setting and accepting realistic short-term and long-range goals. Emphysema is not considered curable and antibiotics are not used on a preventative basis. The patient does not normally need to avoid public places.
A nurse is assessing a patient who is suspected of having bronchiectasis. The nurse should consider which of the following potential causes?
- A. Pulmonary hypertension
- B. Airway obstruction
- C. Pulmonary infections
- D. Genetic disorders
- E. Atelectasis
Correct Answer: B,C,D
Rationale: Bronchiectasis is a chronic, irreversible dilation of the bronchi and bronchioles. Under the new definition of COPD, it is considered a disease process separate from COPD. Bronchiectasis may be caused by a variety of conditions, including airway obstruction, diffuse airway injury, pulmonary infections and obstruction of the bronchus or complications of long-term pulmonary infections, or genetic disorders such as cystic fibrosis. Bronchiectasis is not caused by pulmonary hypertension or atelectasis.
A nurse is creating a health promotion intervention focused on chronic obstructive pulmonary disease (COPD). What should the nurse identify as a complication of COPD?
- A. Lung cancer
- B. Cystic fibrosis
- C. Respiratory failure
- D. Hemothorax
Correct Answer: C
Rationale: Complications of COPD include respiratory failure, pneumothorax, atelectasis, pneumonia, and pulmonary hypertension (cor pulmonale). Lung cancer, cystic fibrosis, and hemothorax are not common complications.
A nurse has been asked to give a workshop on COPD for a local community group. The nurse emphasizes the importance of smoking cessation because smoking has what pathophysiologic effect?
- A. Increases the amount of mucus production
- B. Destabilizes hemoglobin
- C. Shrinks the alveoli in the lungs
- D. Collapses the alveoli in the lungs
Correct Answer: A
Rationale: Smoking irritates the goblet cells and mucous glands, causing an increased accumulation of mucus, which, in turn, produces more irritation, infection, and damage to the lung.
A student nurse is preparing to care for a patient with bronchiectasis. The student nurse should recognize that this patient is likely to experience respiratory difficulties related to what pathophysiologic process?
- A. Intermittent episodes of acute bronchospasm
- B. Alveolar distention and impaired diffusion
- C. Dilation of bronchi and bronchioles
- D. Excessive gas exchange in the bronchioles
Correct Answer: C
Rationale: Bronchiectasis is a chronic, irreversible dilation of the bronchi and bronchioles that results from destruction of muscles and elastic connective tissue. It is not characterized by acute bronchospasm, alveolar distention, or excessive gas exchange.
