Feedback:
Drugs used to treat Alzheimer's disease are metabolized in the liver and excreted in the urine, so caution should be used in the presence of hepatic or renal dysfunction, which could interfere with the metabolism and excretion of the drugs. Dosage adjustments may be needed for neostigmine, edrophonium, and pyridostigmine if the patient has renal disease but they are not contraindicated.
Answer to Question 2
D
Feedback:
The pressure of the blood in the arteries needs to remain relatively high to ensure that blood is delivered to every cell in the body and to keep the blood flowing from high-pressure to low-pressure areas. The pressure can fall dramaticallythis is called hypotensionfrom loss of blood volume or from failure of the heart muscle to pump effectively. Severe hypotension can progress to shock and even death as cells are cut off from their oxygen supply. An infection would result in septic shock. Many types of shock exist. Inadequate supply of oxygen via the coronary arteries results in a myocardial infarction. Reduced pumping action of the heart is called heart failure.
