A nurse in the Medical-Surgical unit is caring for a client who has had an allogeneic hematopoietic stem-cell transplant. Which of the following infection-control precautions should the nurse use while caring for this client?

Choice A rationale:

Dyspnea (shortness of breath) is a common finding in clients with emphysema. Emphysema is a chronic obstructive pulmonary disease characterized by the destruction of lung tissue, leading to reduced lung elasticity and airflow limitation, which can result in difficulty breathing.

Choice B rationale:

Clubbing of the fingers is another expected finding in clients with advanced emphysema. Clubbing is the swelling and rounding of the fingertips, often associated with chronic respiratory conditions. It is thought to be a result of chronic hypoxia and inadequate oxygenation.

Choice C rationale:

Deep respirations are not typically associated with emphysema. Clients with emphysema often exhibit shallow, rapid respirations due to the loss of lung tissue elasticity, which impairs the normal respiratory mechanics.

Choice D rationale:

Bradycardia (slow heart rate) is not a common finding in emphysema. Emphysema primarily affects the respiratory system and does not directly influence heart rate. Bradycardia could be related to other factors but is not a characteristic finding of emphysema.

Choice E rationale:

Barrel chest is a classic physical finding in clients with emphysema. It results from the hyperinflation of the lungs due to the trapping of air in the damaged alveoli. This gives the chest a rounded appearance, similar to the shape of a barrel.

Choice A rationale:

Asthma - Asthma is a chronic respiratory condition characterized by bronchoconstriction, inflammation, and increased mucus production. It does not typically present with absent breath sounds, deviation of the trachea, or hyperresonant percussion sounds. Wheezing is a common finding in asthma.

Choice B rationale:

Pneumothorax - This is the correct choice. The scenario describes classic signs of a tension pneumothorax, which is a medical emergency. The tracheal deviation, absence of breath sounds, and hyperresonant percussion note on the affected side are indicative of air accumulation in the pleural space, leading to lung collapse and displacement of mediastinal structures.

Choice C rationale:

Atelectasis - Atelectasis refers to the collapse or incomplete expansion of a lung or part of a lung. It can lead to decreased breath sounds on auscultation but does not usually cause tracheal deviation or hyperresonance on percussion. It is not the best fit for the described signs.

Choice D rationale:

Pneumonia - Pneumonia is an infection of the lung tissue that can cause symptoms like fever, cough, and productive sputum. Breath sounds may be diminished over the affected area due to consolidation, but the absence of breath sounds, tracheal deviation, and hyperresonance point more strongly toward a pneumothorax in this case.
