Answer to Question 1

B
Increased fluids can combat the hypotensive effects of alpha-adrenergic blockers such as terazo-sin. Ginkgo biloba can amplify the anticoagulant effect of warfarin, leading to an increased risk of bleeding. Reduced sodium intake contributes to the toxicity of lithium. Leafy, green vegeta-bles can diminish the anticoagulant effect of warfarin (Coumadin).

Answer to Question 2

B

Feedback
A Incorrect. This statement is true. Constipation is present when there are fewer than three bowel movements per week or when the frequency decreases.
B Correct. This statement is not true. Mineral oil and saline laxatives can be harmful. Fiber, fruit, and fluids are recommended first; stimulant laxatives such as senna and cascara can be used on a short-term basis.
C Incorrect. This statement is true. These behaviors may be the only clinical symptom of constipation in cognitively impaired older persons.
D Incorrect. This statement is true. Liquid feces may be leaking around a fecal impaction, and antidiarrheal treatment can aggravate the impaction.
