A nurse is developing an in-service about personality disorders.
Which of the following information should the nurse include when discussing borderline personality disorder?

The correct answer is A. Uses a firm-bristled toothbrush increases the client's risk for injury because it can cause bleeding gums and oral mucosal damage in clients with pernicious anemia, who have reduced platelet count and impaired clotting. The other findings do not increase the risk for injury and may be beneficial for clients with pernicious anemia. Increased intake of green, leafy vegetables provides folic acid, which is essential for red blood cell production. Drinks 2,500 mL of fluid per day prevents dehydration and maintains blood volume. Wears a face mask around others reduces exposure to infections, which can be serious in clients with pernicious anemia, who have impaired immunity due to low white blood cell count.

Choice A rationale:

Paradoxical chest movement refers to the abnormal inward movement of the chest during inhalation and outward movement during exhalation. It is not a typical finding in pneumothorax. Instead, paradoxical chest movement is often observed in conditions such as flail chest.

Choice B rationale:

Reduced right-sided breath sounds are a common finding in right pneumothorax. Air in the pleural space can cause lung collapse, leading to decreased or absent breath sounds on the affected side.

Choice C rationale:

High-pitched stridor is a sound heard during inspiration and indicates upper airway obstruction, often due to conditions like croup or epiglottitis. It is not a characteristic finding in pneumothorax.

Choice D rationale:

Intercostal retractions occur when the tissues between the ribs are pulled inward during inspiration. While retractions can be seen in various respiratory distress conditions, they are not specific to pneumothorax.
