A client has a systolic blood pressure of over 200 mm Hg and a severe headache.
The physician orders a nicardipine infusion. What should the nurse explain to the family about the use of this medication?

This scenario requires differentiating between various neurological conditions based on the sudden onset of focal deficits and altered mental status. Recognizing the hallmarks of acute ischemia or hemorrhage is vital for ensuring the patient receives rapid, time sensitive reperfusion therapies.

Choice A rationale

Migraines typically present with unilateral throbbing pain, photophobia, and phonophobia, often preceded by an aura. While they can be severe, they do not usually cause acute facial drooping or the profound confusion associated with a cerebrovascular accident.

Choice B rationale

A stroke involves a sudden interruption of blood flow to the brain, causing rapid onset focal neurological deficits. Facial drooping, confusion, and severe headache are classic signs of either ischemic or hemorrhagic events requiring immediate emergency diagnostic imaging.

Choice C rationale

Trigeminal neuralgia is characterized by sudden, brief, and excruciating paroxysmal facial pain along the branches of the fifth cranial nerve. It does not cause confusion, facial drooping, or a generalized severe headache, as it is a sensory nerve disorder.

Choice D rationale

Meningitis involves inflammation of the meninges, typically presenting with fever, nuchal rigidity, and photophobia. While confusion and headache occur, the onset is usually more gradual than a stroke and does not typically include acute focal facial drooping.

Pyloric obstruction involves a mechanical blockage at the stomach outlet, leading to the accumulation of gastric contents. Knowledge of gastrointestinal decompression and the therapeutic purpose of nasogastric tubes in managing increased intragastric pressure and preventing emesis is required here.

Choice A rationale

Pyloric obstruction causes gastric stasis and distension because contents cannot enter the duodenum. Nasogastric intubation provides decompression by removing accumulated secretions and gas, which relieves pressure, prevents vomiting, and reduces the risk of aspiration in the client.

Choice B rationale

Providing nutrition via tube feeding is contraindicated in pyloric obstruction. Because the outlet of the stomach is blocked, any enteral formula introduced would accumulate in the stomach, worsening distension and significantly increasing the risk of reflux or aspiration.

Choice C rationale

While gastric pH can be measured via a nasogastric tube, it is not the primary therapeutic rationale for tube placement in a client with a mechanical obstruction. Decompression is a critical intervention to ensure safety and comfort.

Choice D rationale

Administering oral medications through a nasogastric tube is ineffective during an obstruction. The medication cannot pass the pylorus to be absorbed in the small intestine, and it adds volume to an already overfilled and pressurized stomach.
