A client with end-stage kidney disease is at risk for anemia due to decreased production of erythropoietin. Which of the following conditions is most likely to contribute to anemia in end-stage renal disease?

Rationale:

A. Decreased range of motion in the affected limb is correct. Contractures are permanent shortening of muscles, tendons, or ligaments that often develop after burn injuries, particularly when deep partial-thickness or full-thickness burns heal with significant scar tissue formation. As scar tissue forms and contracts, it limits joint mobility, leading to restricted range of motion, functional impairment, and deformity. Early recognition and intervention, such as physical therapy, splinting, and proper positioning, are essential to prevent or minimize contractures.

B. Increased muscle strength in the affected limb is incorrect. Contractures result in limited movement and stiffness, not enhanced muscle strength. An increase in strength would suggest recovery and rehabilitation rather than a complication of scarring.

C. Improved flexibility and joint movement is incorrect. Contractures reduce flexibility and impede joint movement. Improved flexibility would indicate successful healing and rehabilitation, not the development of a contracture.

D. Swelling and redness around the burn area is incorrect. While swelling and erythema may occur during the acute inflammatory phase of burn healing, they do not specifically indicate contracture formation. Contractures develop over time as scar tissue matures and tightens, rather than during initial inflammation.

Rationale:

A. In emphysema, destruction of alveolar walls and loss of elastic recoil lead to air trapping and hyperinflation of the lungs. Over time, this causes the diaphragm to flatten as the lungs expand, which is a classic radiographic sign of advanced emphysema. This finding correlates with reduced ventilatory efficiency, increased work of breathing, and progressive respiratory compromise.

B. In emphysema, breath sounds are often decreased due to the destruction of alveoli and hyperinflation of the lungs. Loud or increased breath sounds are more typical in conditions such as bronchospasm or pulmonary edema with turbulent airflow.

C. While early emphysema may present with minimal auscultatory findings and a mild cough, advanced disease is associated with hyperinflated lungs, decreased breath sounds, and sometimes wheezing. Clear lung fields alone do not indicate severe or advanced disease.

D. Bradycardia and constricted pupils are incorrect. These findings are unrelated to emphysema. Bradycardia and miosis may suggest medication effects (e.g., opioids) or neurologic conditions, not pulmonary pathology.
