Question 2

Mr. S is a 60-year-old obese client in for a yearly clinic visit. The nurse assesses his vital signs, and asks him about his current medical problems.
 
  He tells her that he feels fine, plays golf several times a week, and has stopped smoking cigarettes. When she asks about his alcohol intake he tells her that he has started to drink two glasses of wine each night because he heard it is good for his heart. The best response for the nurse would be: 1. Two glasses of wine would be considered drinking in moderation, but any more could cause problems such as hypertension or liver disease..
   2. Any amount of alcohol is bad for your health..
   3. Wine is low in calories so should not cause weight gain..
   4. Wine has definitely been linked with liver cancer and should be avoided..

Answer to Question 1

D
The secondary structure of proteins refers to the straight, folded, or coiled shape of the amino acid chain. The combination of polypeptide chains is the quaternary structure. The sequence of amino acids in the chain is the primary structure. The strong bonds between loops of the chain is the tertiary structure.

Answer to Question 2

1
Rationale: The current recommendation for alcohol intake is one drink per day for small men and women, whereas two drinks would be considered drinking in moderation for larger men. Moderate intake of alcohol can have some health benefits, but in excess has been linked to cancers, hypertension, depression, insomnia, and disorders of the gastrointestinal tract. Wine contains about 125 calories per 5-oz glass.
