Tuberculosis poses a higher risk of transmission via respiratory droplets, making respiratory protection essential to prevent exposure and infection among healthcare workers.

The irritation and inflammation caused by the tumor affect the vocal cords, leading to changes in voice quality. Dysphagia (choice A) typically occurs later as the tumor grows and interferes with swallowing. Dyspnea (choice C) and weight loss (choice D) may occur as the cancer progresses, but hoarseness is usually among the first signs to manifest in laryngeal cancer.

Rationale: Fluctuation of the fluid level within the water seal chamber indicates proper functioning of the chest tube. This fluctuation reflects the normal ebb and flow of air and fluid in the pleural space, demonstrating that the system is maintaining the appropriate pressure.

Rationale: In fat embolism syndrome (FES), fat globules enter the bloodstream and can lead to various complications, including a decrease in serum calcium levels. This occurs due to the formation of fat emboli in the vessels, which can interfere with calcium metabolism. Therefore, a decreased serum calcium level is an expected laboratory finding in a client with fat embolism syndrome.
