A patient has difficulty in breathing. The nurse provides oxygen therapy to the patient, after which the patient feels better. Which principle is involved in this situation?

Choice A rationale:

Cranberry juice causing bad breath is not a well-known side effect or outcome associated with its consumption. This information is not a commonly taught aspect of cranberry juice use.

Choice B rationale:

Bloating is not a common or widely recognized outcome of drinking cranberry juice. While cranberry juice might have some gastrointestinal effects, bloating is not a significant concern associated with its consumption.

Choice C rationale:

Informing the client that drinking cranberry juice daily can prevent recurrent urinary tract infections is accurate. Cranberry juice is often recommended for its potential to reduce the risk of urinary tract infections due to its anti-adhesive properties that may inhibit the adherence of bacteria to the urinary tract.

Choice D rationale:

Cranberry juice's effect on lowering cholesterol is not a well-established benefit of its consumption. Cholesterol management typically involves dietary changes, exercise, and sometimes medications, but cranberry juice is not a primary intervention for this purpose.

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.
