Rationale: Bile acids or bile salts are produced by the liver to emulsify or break down fats. Blockage of the common bile duct impedes the flow of bile from the gallbladder to the duodenum, thus preventing breakdown of fatty intake. Knowledge of this should direct you to whole milk. Dairy products, such as whole milk, ice cream, butter, and cheese, are high in cholesterol and fat and should be avoided.
Answer to Question 2

Rationale: Ngele's rule determines the estimated date of birth and works on the premise that the woman has a 28-day menstrual cycle. To calculate the estimated date of confinement, sub-tract 3 months from the first day of the last menstrual period, add 7 days, and then add 1 year to that date; alternatively, count forward 9 months and add 7 days to the first day of the last men-strual period. Therefore, first day of last menstrual period, February 9, 2012; subtract 3 months, November 9, 2011; add 7 days, November 16, 2011; and add 1 year, November 16, 2012.
