The nurse assesses an older adult client admitted with a new diagnosis of supratentorial glioma who has developed new symptoms.
Which symptom is the most concerning to the nurse?

This clinical presentation requires applying knowledge of Monro-Kellie doctrine and neurological assessment. Understanding how space-occupying lesions like brain tumors affect intracranial dynamics is vital for identifying life-threatening shifts in pressure that manifest as headache, projectile vomiting, and mental status changes.

Choice A rationale

Migraine headaches typically present with unilateral throbbing pain and photophobia but rarely cause sudden, severe altered consciousness in this context. While painful, they do not explain the acute neurological decline associated with a known intracranial tumor.

Choice B rationale

Dehydration usually presents with tachycardia, poor skin turgor, and hypotension. While it can cause lightheadedness or confusion in extreme cases, it does not typically cause the sudden onset of a severe headache and vomiting seen in neurological emergencies.

Choice C rationale

Increased intracranial pressure results from the tumor mass or associated edema. It compresses brain tissue and blood vessels, leading to the classic triad of headache, vomiting, and altered consciousness, signaling a potential brain herniation and neurological crisis.

Choice D rationale

A gastric ulcer causes epigastric pain and potentially hematemesis if perforated. While vomiting may occur, it is unrelated to sudden neurological changes or severe headaches. This diagnosis fails to address the primary intracranial pathology and accompanying mental deficits.

Endotracheal suctioning carries risks of hypoxia and vagal stimulation. Knowledge of respiratory physiology and emergency protocols is required to recognize when a procedure is causing clinical instability and to prioritize the immediate restoration of oxygenation and cardiac rhythm stability.

Choice A rationale

Tachycardia, arrhythmias, and desaturation during suctioning indicate acute hypoxia and myocardial stress. The nurse must stop the procedure immediately to prevent cardiac arrest and provide 100 percent oxygen to restore alveolar gas exchange and stabilize the heart rate.

Choice B rationale

Continuing the procedure while the patient is experiencing cardiac instability and severe hypoxia is dangerous. Prolonged suctioning increases the risk of further vagal stimulation and worsening hypoxemia, which could lead to fatal arrhythmias or sudden respiratory and cardiac collapse.

Choice C rationale

While the provider needs to be informed, it is not the priority. Immediate life saving intervention, such as stopping suctioning and hyper-oxygenating the client, must occur first to address the physiological distress and prevent further deterioration of the client.

Choice D rationale

Antiarrhythmics are not the first line treatment for suction induced arrhythmias. These rhythm changes are usually a direct result of hypoxia. Correcting the underlying oxygen deficiency by stopping the suction and providing supplemental oxygen usually resolves the tachycardia and irregularity..
