Answer to Question 1

ANS: C
The rivastigmine transdermal patch needs to be changed daily. Sites used should not be reused for 14 days. Transdermal dosing provides lower, steady levels of the drug. Intensity of side effects is lower with the transdermal patch. The old patch must be removed prior to applying the new patch to prevent toxicity.

Answer to Question 2

ANS: D
In 2010 an international group of AD experts proposed revising diagnostic criteria to add the presence of at least one AD biomarker to current measures of cognitive function after a patient has been observed to have episodic memory impairment. The diagnosis currently is made by observing memory impairment and then measuring cognitive function. Most medications used for AD do not demonstrate sustained or unequivocal improvement, so they would not be useful for diagnostic purposes. The patient's age and family history are risk factors. The serum ApoE level and genetic testing are not used to diagnose AD. Magnetic resonance imaging (MRI) can measure one brain marker of AD; however, brain atrophy has several different causes and is not definitive.
