A nurse is providing care for several clients on a neurological unit of a hospital. In which of the following clients would the nurse be justified in predicting a problem with thermoregulation?
 
  A)
  A 66-year-old male with damage to his thalamus secondary to a cerebral vascular accident
  B)
  A 22-year-old male with damage to his cerebellum secondary to a motorcycle accident
  C)
  A 68-year-old male with end-stage neurosyphilis
  D)
  A 45-year-old female with a T8 fracture secondary to a diving accident

Question 2

Which of the following physiological processes would be considered a positive feedback mechanism?
 
  A)
  The release of antidiuretic hormone (ADH) from the posterior pituitary gland
  B)
  Shivering in response to low environmental temperature
  C)
  The platelet aggregation mechanism for closing minute ruptures in very small blood vessels during accidental injury
  D)
  Increased production of white blood cells (WBCs) in response to a microorganism

Answer to Question 1

Ans:
A

Feedback:

The thalamus is involved in the sensation and regulation of body temperature. Syphilis, a T8 fracture, and damage to the cerebellum would unlikely manifest by difficulties with thermoregulation.

Answer to Question 2

Ans:
C

Feedback:

The release of hormones during labor increases rather than mitigates a physiological system. Specifically, uterine contraction stimulates the production of other relevant hormones that cause temporary instability that culminates in childbirth. ADH counters the potential instability of insufficient hydration and/or blood pressure, much as shivering is an attempt to counter low temperature. Increased production of WBCs is a response to the potential homeostatic instability of an infectious process.
