The nurse is caring for a client receiving chemotherapy for acute leukemia. The client reports chills and weakness.
Assessment findings include a temperature of 101 F (38.3 C), heart rate 142 beats per minute, blood pressure 80/40 mm Hg, respiratory rate 32 breaths per minute, and O2 saturation 94 Which interpretation by the nurse is most accurate?

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.

Hemodynamic monitoring requires knowledge of pressure dynamics within the right atrium and vena cava. Central venous pressure reflects right heart preload and fluid volume status. Increased readings indicate either fluid volume excess or impaired pumping ability of the right ventricle.

Choice A rationale

. Increased cardiac output typically relates to efficient ventricular contraction and does not directly cause an elevated central venous pressure. High output states might actually reflect lower pressures if the volume is moving effectively. It is not the primary cause of pressure backup.

Choice B rationale

. Dehydration leads to a decrease in circulating blood volume, which results in a low central venous pressure reading. Normal CVP ranges from 2 to 8 mmHg. A reading below this range typically indicates a need for intravenous fluid resuscitation.

Choice C rationale

. When the right ventricle fails, it cannot effectively pump blood into the pulmonary circulation. This causes blood to back up into the right atrium and vena cava. This congestion results in a measurable rise in the central venous pressure reading.

Choice D rationale

. Hypovolemia represents a state of low intravascular volume, which reduces the pressure exerted on the walls of the great veins. This leads to a decreased CVP reading. It is the physiological opposite of the volume overload seen in heart failure.
