A patient diagnosed with depersonalization disorder tells the nurse, It's starting again. I feel as though I'm going to float away. The nurse should help the patient by:

  • A. encouraging meditation.
  • B. administering an anxiolytic medication.
  • C. helping the patient visualize a pleasant scene.
  • D. helping the patient focus on the here and now.
Correct Answer: D

Rationale: The correct answer is D: helping the patient focus on the here and now. This is appropriate for depersonalization disorder as it helps the patient ground themselves in reality and reduce dissociative symptoms. Encouraging meditation (A) may exacerbate dissociation by further disconnecting the patient from reality. Administering an anxiolytic medication (B) may provide temporary relief but does not address the underlying issue. Helping the patient visualize a pleasant scene (C) may be soothing but may not be effective in addressing the dissociative symptoms.

Which part of the neuron has the highest concentration of Na.

  • A. dendrites
  • B. cell body
  • C. synaptic knobs
  • D. none of them
Correct Answer: D

Rationale: The intracellular concentration of Na+ is generally low in all parts of the neuron due to the action of the Na+, K+ ATPase pump, which actively transports Na+ out of the cell. Therefore, none of the listed parts have a high concentration of Na+.
