Correct Answer: B

Rationale: In clients with laryngeal cancer, hoarseness is often one of the earliest manifestations due to vocal cord involvement. 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.

Correct Answer: A

Rationale: Preventing aspiration is the priority for a client with intermaxillary fixation following mandibular surgery. Aspiration can occur due to difficulty swallowing or improper positioning, posing a serious risk to the client's respiratory status. It is crucial for the nurse to ensure that the client's airway is clear and that they are positioned correctly to prevent any potential aspiration events.

Correct Answer: D

Rationale: Gastroenteritis can lead to fluid loss through vomiting and diarrhea, especially when accompanied by fever. Fever can increase insensible water loss through sweating as well. Both vomiting and diarrhea can significantly contribute to fluid volume deficit, making the client with gastroenteritis and fever at higher risk compared to the other clients described in the options.

Correct Answer: C

Rationale: An OSHA-approved N95 respirator mask is recommended when caring for a client with tuberculosis due to the airborne transmission of the disease. Tuberculosis poses a higher risk of transmission via respiratory droplets, making respiratory protection essential to prevent exposure and infection among healthcare workers.

Correct Answer: A

Rationale: The movement of the trachea toward the unaffected side is concerning as it can indicate a tension pneumothorax, a life-threatening emergency that requires immediate intervention. The trachea should be midline, so any deviation should be reported promptly to the provider for further evaluation and intervention.
