The ankle–brachial index (ABI) is calculated by dividing the systolic BP at the dorsalis pedis by the systolic BP at the brachial artery. Which of the following values would be consistent with mild peripheral arterial disease?
A) 1.1
B) 0.85
C) 0.65
D) 0.35
B) 0.85
The mild disease is represented by an ABI of 0.71 to 0.9. Any value above 0.9 is normal. Moderate disease is defined as between 0.7 and 0.41, and severe disease is defined as 0.4 or less. Patients in the “severe” category have a 20% to 25% annual risk of death.

An adult male has a new diagnosis of Guillain-Barré syndrome. The nurse knows which of the following pathophysiological processes underlie the deficits that accompany the degeneration of myelin in his peripheral nervous system (PNS)?
A) The destruction of myelin causes fewer Schwann cells to be produced in the client's PNS. B) The axonal transport system is compromised by the lack of myelin surrounding nerve cells. C) Unless remyelination occurs, the axon will eventually die. D) A deficit of myelin predisposes the client to infection by potential pathogens.
Use the information contained in this chapter and related learning activities to prepare a brief outline of what needs to be incorporated into the design and functionality of the clinical decision support system. The outline should include the following:
• aim(s) of the clinical decision support system (e.g. reduce hypoglycaemic events) • target patient population and potential users of the system • features that will be important to the success of this particular system • methods for evaluating its effectiveness. What will be an ideal response?
