A nurse is collecting data from a client who has Graves' disease.
Which of the following signs should the nurse identify as an indication that the client is experiencing exophthalmos?

Choice A rationale

Oatmeal is not rich in vitamin C, which is needed to enhance the absorption of ferrous sulfate. While it provides fiber, its role in iron therapy is limited compared to vitamin C-rich options, which significantly improve iron solubility and uptake.

Choice B rationale

Raw oranges are an excellent source of vitamin C, which significantly enhances the absorption of non-heme iron like ferrous sulfate. Vitamin C reduces ferric iron to ferrous iron, promoting absorption in the duodenum, a critical factor in anemia management.

Choice C rationale

Baked potatoes contain minimal vitamin C compared to other food options like citrus fruits. While they have nutritional benefits, they do not significantly enhance iron absorption, making them less effective for optimizing ferrous sulfate therapy.

Choice D rationale

Cheese is calcium-rich, and calcium competes with iron for absorption in the gastrointestinal tract. Consuming calcium alongside ferrous sulfate can decrease its bioavailability, making cheese an unsuitable choice for improving iron absorption. .

Choice A rationale

Remaining flat in bed post-thoracentesis can impair respiratory function by reducing lung expansion. Proper positioning facilitates pleural fluid clearance and reduces dyspnea risk. Elevating the head enhances ventilation and drainage, improving post-procedural recovery and minimizing complications.

Choice B rationale

Post-procedure chest x-rays confirm successful fluid removal and monitor for complications like pneumothorax, common after pleural interventions. Imaging validates lung re-expansion and ensures pleural integrity, critical for addressing new or worsening respiratory distress symptoms.

Choice C rationale

Aseptic, not clean technique, minimizes infection risk during thoracentesis. Sterile precautions protect against bacterial introduction into the pleural space, which can cause empyema, a severe complication. All materials and the procedure field should meet sterile standards.

Choice D rationale

Urinary catheter insertion is unrelated to thoracentesis and poses unnecessary infection risks. The procedure focuses on resolving pleural fluid issues, and urinary monitoring is not standard unless clinically indicated for other medical concerns. .
