  A)
  The client has decreased deep tendon reflexes.
  B)
  The client displays increased muscle tone.
  C)
  The client's muscles appear atrophied.
  D)
  The client displays weakness in the distal portions of his limbs.

Question 2

Which of the following individuals would most likely experience global ischemia to his or her brain?
 
  A)
  A male client who has just had an ischemic stroke confirmed by CT of his head
  B)
  A woman who has been admitted to the emergency department with a suspected intracranial bleed
  C)
  A man who has entered cardiogenic shock following a severe myocardial infarction
  D)
  A woman who is being brought to hospital by ambulance following suspected carbon monoxide poisoning related to a faulty portable heater

Answer to Question 1

Ans:
B

Feedback:

UMNs typically produce increased muscle tone, while hyporeflexia, muscle atrophy, and weakness in the distal portion of limbs are more commonly indicative of LMN lesions.

Answer to Question 2

Ans:
C

Feedback:

Global ischemia is associated with a cessation of blood flow to the entire brain, as often occurs during cardiac arrest or myocardial infarction. Ischemic stroke and intracranial bleeding are likely to cause focal ischemia; carbon monoxide toxicity is associated with hypoxia.
