Answer to Question 1

Correct Answer: 4
Rationale 1: Elderly people with heart failure are not usually at risk for thiamine deficiency.
Rationale 2: Pregnant women and children are not usually at risk for thiamine deficiency in the United States.
Rationale 3: Thiamine deficiency in the United States is not common in African American women.
Rationale 4: Alcoholics with chronic liver disease have the highest incident of thiamine deficiency in the United States.
Global Rationale: Because of its abundance in food, thiamine deficiency in the United States is not common, except in people with chronic alcoholism or chronic liver disease and in patients following bariatric surgery. Persons with heart failure, pregnant women, children and African American women are not at increased risk for thiamine deficiency.

Answer to Question 2

Correct Answer: 3
Rationale 1: Vitamin B6, a water-soluble vitamin, is excreted in the urine.
Rationale 2: Mental confusion and hallucinations are not caused by vitamin B6.
Rationale 3: Vitamin B6 reverses the therapeutic effects of the anti-Parkinson drug levodopa.
Rationale 4: Vitamin B6 does not increase the amount of dopamine in the brain.
Global Rationale: This vitamin may reverse or antagonize the therapeutic effects of the antiparkinsonism drug levodopa because it reduces the amount of dopamine entering the brain by facilitating the breakdown of levodopa in peripheral circulation. It does not cause mental confusion and hallucinations. It is water soluble and is excreted in the urine.
