A nurse is providing discharge teaching for a client who requires home oxygen therapy. Which of the following statements should the nurse identify as an indication that the client needs further teaching?

Choice A rationale:

Pneumonia is not likely to be the correct answer. Pneumonia is often characterized by productive cough, fever, chest pain, and increased tactile fremitus due to consolidation of lung tissue. The presence of barrel chest, decreased tactile fremitus, and hyperresonant percussion sounds is not consistent with pneumonia.

Choice B rationale:

Atelectasis is not the most likely option. Atelectasis refers to collapsed or partially collapsed lung tissue, which can lead to decreased breath sounds, dullness to percussion, and decreased tactile fremitus. The symptoms mentioned in the scenario, such as prolonged expiration, wheezes, and barrel chest, are not indicative of atelectasis.

Choice C rationale:

Pleural effusion is not the most suitable choice. Pleural effusion usually presents with decreased breath sounds, dullness to percussion, and decreased tactile fremitus over the affected area due to fluid accumulation in the pleural space. The hyperresonant percussion sounds and the presence of wheezes and rhonchi do not align with pleural effusion.

Choice D rationale:

Emphysema is the most likely disorder based on the given symptoms. Barrel chest (increased anterior-posterior chest diameter), limited lung expansion, decreased tactile fremitus, hyperresonant percussion sounds, prolonged expiration, wheezes, and rhonchi are characteristic findings of emphysema. This condition involves damage to the alveoli and their supporting structures, leading to air trapping, reduced lung elasticity, and obstructed airflow. The patient's use of accessory muscles to breathe further suggests a chronic obstructive pulmonary disease (COPD) like emphysema.

Choice A rationale:

The choice "Patient ate half of his breakfast tray" is not the correct answer. While poor appetite or decreased intake can impact a patient's nutritional status, it is not a direct indicator of pressure ulcer risk.

Choice B rationale:

The choice "Patient has a raised erythematous rash below the knee" is not the correct answer. This might indicate a localized skin issue, such as an allergic reaction or dermatitis, but it is not a clear sign of pressure ulcer risk.

Choice C rationale:

The choice "Patient has a capillary refill of less than 2 seconds" is not the correct answer. Capillary refill time assesses peripheral circulation and is useful in evaluating perfusion, but it is not specifically indicative of pressure ulcer risk.

Choice D rationale:

The correct answer is "Patient is incontinent of stool." Choice D is the correct answer. Incontinence, especially fecal incontinence, increases the risk of pressure ulcer development. Prolonged exposure to moisture from urine or stool weakens the skin's integrity, making it more susceptible to breakdown when pressure is applied over bony prominences.
