A client with subdural hematoma was given mannitol to decrease intracranial pressure (ICP). Which of the following results would best show the mannitol was effective?
- A. Urine output increases
- B. Pupils are 8 mm and nonreactive
- C. Systolic blood pressure remains at 150 mm Hg
- D. BUN and creatinine levels return to normal
Correct Answer: A
Rationale: An increase in urine output is the most direct indicator of mannitol's effectiveness. Mannitol works by promoting osmotic diuresis, which increases urine production. This reduces fluid volume in the brain, thereby decreasing ICP. While other signs like pupil reactivity and blood pressure are important, they are secondary indicators and may not directly correlate with the drug's immediate effect.

Certain metabolic diseases can affect the nervous system. For instance, people with diabetes can develop a nervous system problem called diabetic neuropathy. What are the symptoms of diabetic neuropathy?
- A. Constipation or diarrhea
- B. Rapid heart beat
- C. Pain in feet
- D. All of the above
Correct Answer: D
Rationale: Diabetic neuropathy can cause a wide range of symptoms, including gastrointestinal issues like constipation or diarrhea, cardiovascular symptoms like rapid heart rate, and sensory symptoms like pain in the feet.

In the context of brain imaging, what does FMRI stand for?
- A. fast moving recovery imaging
- B. first moveable recording indicator
- C. flexible motion resistance indicator
- D. functional magnetic resonance imaging
Correct Answer: D
Rationale: Functional Magnetic Resonance Imaging (fMRI) is a brain imaging technique that measures brain activity by detecting changes in blood flow. When a brain region is active, it consumes more oxygen, and fMRI captures this increased blood flow. This non-invasive method is widely used in neuroscience to study brain function and map neural activity during various tasks. fMRI has revolutionized our understanding of the brain's organization and function.
What is a disadvantage of open reduction and internal fixation of a fracture compared to closed reduction?

- B. Skin irritation
- C. Nerve impairment
- D. Complications of immobility
Correct Answer: A
Rationale: Open reduction involves surgery, which increases the risk of infection.
