Questions and Answers

A patient presents with disorganized thinking, hallucinations, and delusions. Which action demonstrates the application of understanding schizophrenia within a comprehensive treatment plan?

  • Immediately involving the patient in group therapy sessions to promote social interaction.
  • Focusing solely on pharmacological interventions to control psychotic symptoms.
  • Integrating symptom identification into the patient's assessment while tailoring interventions to address specific needs. (correct)
  • Encouraging the patient to confront delusional beliefs directly to promote reality testing.

What is the priority when formulating a nursing diagnosis for a patient with schizophrenia?

  • Ignoring the family's input to ensure interventions align with established protocols.
  • Focusing on the patient's past behaviors and triggers to psychotic episodes.
  • Developing broad, generalized goals applicable to all patients with schizophrenia.
  • Identifying expected outcomes that lead to improved daily functioning and enhanced quality of life. (correct)

A patient experiencing a manic episode exhibits flight of ideas and inflated self-esteem. Which nursing diagnosis is MOST appropriately aligned with these symptoms?

  • `Disturbed Thought Processes` related to cognitive distortions.
  • `Risk for Injury` related to impulsive behavior and poor judgment. (correct)
  • `Deficient Knowledge` related to lack of understanding about bipolar disorder.
  • `Impaired Social Interaction` related to difficulty maintaining relationships.

Study Notes

Algorithmic Complexity

  • It is a measure of the resources an algorithm needs to solve a problem of a certain size.
  • It allows for comparing the efficiency of algorithms for the same task.

Time Complexity

  • Represents the time an algorithm takes to run based on the size of the input.

Space Complexity

  • Represents the memory space an algorithm requires based on the size of the input.

Big O Notation

  • It describes the asymptotic behavior of functions mathematically.
  • It is used to classify algorithms by how their time or space needs grow with input size.

Common Complexities

  • O(1): Constant time
  • O(log n): Logarithmic time
  • O(n): Linear time
  • O(n log n): Linearithmic time
  • O(n^2): Quadratic time
  • O(n^3): Cubic time
  • O(2^n): Exponential time
  • O(n!): Factorial time
  • Description: Find a target element by checking each element in the array.
  • Time complexity: O(n)
  • Space complexity: O(1)
  • Description: Find a target element by halving the search interval repeatedly (array must be sorted).
  • Time complexity: O(log n)
  • Space complexity: O(1)

Selection Sort

  • Description: Repeatedly selects the minimum element from the unsorted portion and places it at the beginning.
  • Time complexity: O(n^2)
  • Space complexity: O(1)

Merge Sort

  • Description: Divides the array into halves, sorts each half, and merges the sorted halves
  • Time complexity: O(n log n)
  • Space complexity: O(n)
