The neurologic assessment of a patient indicated impaired function of the glossopharyngeal nerve (CN 10) and the vagus nerve (C.N X). Based on these findings, the nurse plans to;
insert an oral airway and suction as needed.
withhold oral fluids and food.
apply artificial pears to protect the cornea.
speak clearly while facing the patient.
The Correct Answer is B
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.

Correct Answer is C
Explanation
A) Prevent the drainage by applying a tight pressure dressing:
Applying a tight pressure dressing is not the appropriate intervention in this case. The presence of fluid draining from the ear, particularly a yellow stain, could indicate cerebrospinal fluid (CSF) leakage, which is a potential sign of a skull fracture or traumatic brain injury (TBI) involving the base of the skull. Applying a tight pressure dressing could potentially increase pressure or cause further injury.
B) Administer antibiotics due to increased risk of infection:
While there is an increased risk of infection with a CSF leak, antibiotics should not be administered immediately unless there is clear evidence of an infection. The priority action is to identify whether the fluid is CSF, as antibiotics alone will not address the underlying issue of a CSF leak. The nurse should allow the fluid to drain, collect a sample, and notify the healthcare provider for further assessment, which may include imaging or testing for the presence of CSF.
C) Allow fluid to drain from the patient's ear onto gauze and notify the healthcare provider:
The yellow stain around the fluid dripping from the patient's ear suggests the possibility of CSF leakage, a sign of a skull base fracture. CSF leakage may occur after a traumatic brain injury and should be handled carefully. The nurse's priority action is to allow the fluid to drain onto gauze to prevent the buildup of pressure and to prevent further leakage into the ear canal. The nurse should also immediately notify the healthcare provider for further evaluation and management.
D) Hang intravenous (IV) fluids to replace fluids lost and prevent dehydration:
While IV fluids may be necessary in some cases for patients with trauma, the priority in this situation is to identify the source and nature of the drainage. If the fluid is CSF, it may be important to manage the leak appropriately rather than focusing solely on replacing fluids. The nurse should first confirm whether the fluid is CSF and notify the healthcare provider for further assessment and management. Replacing fluids may be necessary, but it is not the immediate priority.
Correct Answer is B
Explanation
A) Establish IV access, apply 2L O2 via nasal cannula, and notify provider:
While establishing IV access and providing oxygen are important aspects of managing many emergencies, this patient's symptoms suggest the presence of autonomic dysreflexia rather than a primary respiratory or circulatory issue. In autonomic dysreflexia, the primary concern is to remove the noxious stimulus (such as a full bladder, bowel impaction, or tight clothing) that is causing the severe hypertension and bradycardia.
B) Assess below injury for noxious stimuli, anticipate order for hypertensive medication:
The patient’s symptoms are consistent with autonomic dysreflexia, a serious condition that occurs in individuals with a spinal cord injury at or above the T6 level. The body’s autonomic nervous system overreacts to noxious stimuli (such as a distended bladder, bowel impaction, or skin irritation) below the level of injury, leading to a severe hypertensive crisis, bradycardia, and sympathetic hyperactivity. The nurse should immediately assess for and relieve any noxious stimuli below the injury level (e.g., checking for a full bladder, constipation, or tight clothing) and anticipate an order for antihypertensive medications if the blood pressure remains elevated.
C) Administer acetaminophen and initiate intravenous (IV) fluids, anticipate order for atropine:
While pain and discomfort (which can exacerbate autonomic dysreflexia) may need to be managed, acetaminophen is not the priority in this case. The priority is addressing the underlying cause of autonomic dysreflexia, such as relieving noxious stimuli. Additionally, atropine is used for bradycardia, but in autonomic dysreflexia, the bradycardia is secondary to the hypertensive crisis and usually resolves once the noxious stimulus is removed.
D) Lower the head of the bed and apply a cool compress to the forehead:
Although lowering the head of the bed may help reduce intracranial pressure and applying a cool compress may provide comfort, these interventions do not address the underlying cause of the autonomic dysreflexia.
