A client presents to the emergency room reporting sudden, sharp pain on the right side of the chest and shortness of breath. The right side of the chest is not moving with inspiration. The client's trachea is deviated towards the left: there is absence tactile fremitus on the right side of the chest. Upon percussion, the nurse hears hyperresonant sound on the right side of the thorax. Upon auscultation, no breath sounds are heard on the right. Which disorder would the nurse suspect?

Choice A rationale:

Cyanosis - Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. This is an objective sign that can be visually assessed, not based on the patient's description.

Choice B rationale:

Petechiae - Petechiae are small, pinpoint, red or purple spots on the skin caused by bleeding under the skin. Like cyanosis, this is a physical finding that can be observed directly.

Choice C rationale:

Dizziness - This is the correct choice. Dizziness is a subjective sensation that the patient experiences. It cannot be directly observed and relies on the patient's description of feeling unsteady, lightheaded, or having a spinning sensation.

Choice D rationale:

Blood pressure - Blood pressure is an objective measurement that can be taken using a blood pressure cuff and a stethoscope or automated device. It is not based on the patient's description and does not fall under subjective data.

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.
