Answer to Question 1
A
Most medications bind to albumin to some extent. When medications bind to albumin, they are unable to exert pharmacological activity. Only the unbound or free medication is active. Older adults and patients with liver disease or malnutrition have reduced albumin, which increases their risk for medication toxicity. With less albumin to bind with the medication, more free or active medication is present in the body. This would result in an increase in therapeutic effect and possibly in toxicity. Most biotransformation occurs in the liver, although the lungs, kidneys, blood, and intestines also play a role. Patients (e.g., elderly, those with chronic disease) are at risk for medication toxicity if their organs that metabolize medications do not function correctly.
Answer to Question 2
D
When performing active-assisted or passive ROM exercises, support the joint by holding the distal portion of the extremity, or by using a cupped hand to support the joint. The joint should be flexed to the point of resistance, not to the point of discomfort. Assess the patient's level of comfort (on a scale of 0 to 10, with 10 being the worst pain) before performing exercises. Before beginning ROM exercises, determine whether the patient would benefit from pain medication. Joints should be moved slowly through the ROM. Quick movement could cause injury.
