1. Which meal contains the best sources of dietary fiber?
a.
Eggs, bacon, orange juice
b.
Salad, whole wheat toast, sliced peach
c.
Roast beef, mashed potatoes with gravy, corn, milk
d.
Grilled hamburger on a bun, fresh carrot sticks, potato chips

ANS: B
Good dietary sources of fiber include fresh fruits, vegetables, and whole grain foods. There is little fiber in eggs, bacon, and orange juice and much fat and sugar. Although there is fiber in the menu of roast beef, mashed potatoes, corn, and milk as well as a hamburger on a bun, carrot sticks, and potato chips, these are not the best sources of dietary fiber.

According to the National Academy of Sciences, a moderate intensity physical activity would include walking at a rate of 4 to 5 miles/hour four to seven times weekly. Walking 2 miles daily in 1 hour four times weekly is below a moderate level of activity. Jogging 4 miles in 20 minutes three times weekly and jogging 2 miles in 20 minutes twice weekly is beyond a moderate level of activity.

4. Which dietary fats are cardioprotective?
a.
Monounsaturated
b.
Polyunsaturated
c.
Saturated
d.
Trans

ANS: A
Monounsaturated fats decrease low-density lipoprotein (LDL) and increase high-density lipoprotein (HDL) and are considered to be cardioprotective. Polyunsaturated fats also lower LDL and raise HDL but are not considered to be cardioprotective. Saturated fats raise both LDL and HDL and are thought to increase atherosclerotic plaque formation in the arteries. Trans fats may induce more heart disease than saturated fats because in addition to raising LDL cholesterol, trans fats decrease HDL cholesterol and increase triglycerides, as well as another undesirable blood fat, lipoprotein.

5. A patient is receiving continuous tube feedings at 100 mL/hr. At 1400, the nurse determines that there is 175 mL of residual volume. Which action will the nurse take?
a.
Continue the feedings as ordered.
b.
Reduce the feeding by 50%.
c.
Stop the feeding and notify the health care provider.
d.
Aspirate and dispose of the residual and restart the feeding.

ANS: C
When the residual volume of a tube feeding exceeds 100 mL (or the limit set by the health care provider), the tube feeding is stopped and the residual volume is rechecked within 1 hour. When the residual volume has returned to the limits set by the health care provider, it is restarted. Because the residual amount already exceeds the recommended amount, the feeding should not continue. Infusion rate should not be changed without an order from the health care provider.
