- A) NMES guarantees complete recovery in all cases.
** - B) NMES accelerates healing but may not improve function.**
- C) NMES ensures immediate improvement in mental alertness.
- D) NMES replaces the need for medication in pain management.
- Answer: B) NMES accelerates healing but may not improve function.

- D) Adjust intensity/duration to prevent overstimulation.
- Answer: D) Adjust intensity/duration to prevent overstimulation.
- Rationale: Patients with impaired sensation may not accurately perceive discomfort, making it crucial to adjust intensity and duration to avoid overstimulation and potential injury.
What is a significant risk associated with direct current (DC) in electrical modalities?
- A) Skin irritation or inflammation
- B) Accelerated tissue healing
- C) Electrothermal burns
- D) Improved mental alertness

- A) Skin irritation or inflammation
- B) Accelerated tissue healing
- C) Electrothermal burns
- D) Improved mental alertness
- Answer: C) Electrothermal burns
- Rationale: Direct current (DC) can leave charges in the tissue, leading to electrothermal effects and an increased risk of burns.
