Answer to Question 1

ANS: C
Higher flow (up to 100 L/min) may improve gas exchange in COPD patients, probably because of the resulting increase in expiratory time.

Answer to Question 2

ANS: A
To decrease inspiratory time, one may increase the peak flow, decrease the tidal volume, or change from a down ramp or sine wave to a square wave flow pattern.

Bisphosphonates were first developed in the nineteenth century. They were first investigated for use in disorders of bone metabolism in the 1960s. They are now used clinically for the treatment of osteoporosis, Paget's disease, bone metastasis, multiple myeloma, and other conditions that feature bone fragility.

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
