The nurse is caring for a patient with multiple traumatic injuries following an occupational accident where the patient fell from a 30ft high ladder. Upon assessment, the-nurse hears bowel sounds in the chest. What should the nurse do next?

A) Insert an oral airway and suction as needed:
This is generally not the first intervention for impaired glossopharyngeal (CN IX) and vagus nerve (CN X) function. The glossopharyngeal and vagus nerves play a critical role in swallowing, gag reflex, and the ability to protect the airway. While an airway might be necessary in cases of severe dysfunction, withholding food and fluids is a more immediate and specific concern when these cranial nerves are impaired, as it prevents aspiration risk.

B) Withhold oral fluids and food:
The glossopharyngeal nerve (CN IX) is involved in taste and swallowing, and the vagus nerve (CN X) is crucial for the motor control of the pharynx and larynx, which are involved in swallowing and protecting the airway. Dysfunction of these nerves can lead to difficulty swallowing (dysphagia), increased risk for aspiration, and the inability to protect the airway effectively. Withholding oral fluids and food helps prevent aspiration, a major risk when these nerves are impaired, until further assessment and management can be done.

C) Apply artificial tears to protect the cornea:
While it is important to protect the cornea in patients with cranial nerve dysfunction (specifically the facial nerve, CN VII), this does not directly relate to the glossopharyngeal (CN IX) and vagus (CN X) nerves. The glossopharyngeal and vagus nerves affect swallowing and airway protection, not eye lubrication. Applying artificial tears would not address the risk associated with impaired swallowing or airway protection.

D) Speak clearly while facing the patient:
Although speaking clearly and facing the patient might be helpful for communication, especially if the patient has difficulty with speech due to nerve impairment, it does not address the immediate and more critical concern of impaired swallowing and airway protection associated with dysfunction of the glossopharyngeal and vagus nerves. The primary concern is ensuring the patient is not at risk for aspiration while eating or drinking.

A) Treatment plan will need to be changed to achieve the desired effect:
The decrease in the carcinoembryonic antigen (CEA) levels from 50 ng/mL to 10 ng/mL suggests that the cancer is responding to the current treatment, not that the treatment plan needs to be changed. A drop in CEA levels typically indicates a positive response to treatment, such as chemotherapy, in reducing the number or size of cancer cells.

B) Cancer treatment is having the desired effect on killing cancer cells:
Carcinoembryonic antigen (CEA) is a tumor marker that is often elevated in individuals with certain cancers, particularly colorectal cancer. A decrease in CEA levels, as noted in this case (from 50 ng/mL to 10 ng/mL), usually signifies that the treatment is successfully targeting the cancer and reducing the tumor burden. This drop suggests that the chemotherapy is effectively killing cancer cells and reducing the size or activity of the tumor.

C) Client is at greater risk for tumor lysis syndrome:
Tumor lysis syndrome typically occurs when large numbers of cancer cells die rapidly, releasing their intracellular contents into the bloodstream, which can lead to metabolic disturbances like hyperkalemia, hyperphosphatemia, and renal failure. It is more common in aggressive hematologic cancers, such as leukemia or lymphoma, and typically presents with a rapid rise in tumor marker levels, not a decrease.

D) Cancer has increased size and metastatic sites:
An increase in tumor size or the development of metastatic sites would typically result in an increase in CEA levels, not a decrease. Since CEA levels have dropped, it is more likely that the cancer is shrinking or responding to the current treatment. This finding is more indicative of a positive response rather than disease progression.
