She is careful to maintain a nutrition- ally balanced diet, but a blood test shows that she is deficient in at least one major nutrient. H, blockers are known to sometimes interfere with absorption of which nutrient(s)? a. Vitamin B 2 b. Vitamin C c. Iron d. Magnesium e. Folate on a in t(s) to 32. The largest portion of nutrients is absorbed into the bloodstream from the a. Stomach b. Small intestine. c. Liver. d. Large intestine. 33. Most water absorption occurs in the a. Stomach b. Small intestine. c. Liver. d. Large intestine. 34. The purpose of the blue pigtail of a double-lumen nasogastric (NG) tube is to a. Allow instillation of fluids into the stomach while leaving the other lumen plugged. b. Instill formula if the primary lumen clogs. c. Serve as an air vent. d. Prevent the tube from adhering to the stomach wall during decompression. 35. Which action is considered the most reliable for checking tube placement to confirm the correct initial placement of the NG tube after insertion? a. Aspirate contents b. Measure the pH of aspirate c. Take an X-ray d. Measure the length of the tube that extends from the nares

Answer 1

31, a, Vitamin B12
People who take high dose of H2 blockers more prone to develop a vitamin B12 deficiency, because vitamin B12 in food attached to protein. H2 blockers do not interfere with the absorption of vitamin c, iron, magnesium and folate, possibly help for absorption.
32, b, small intestine
It absorbs most of the nutrients from food and circulates and store in our body for use. liver digest some fats and vitamins, stomach help mix with the food and digestive juice and empty into small intestine. large intestine absorbs water and eliminates waste into stool.
33, d, large intestine
Water and nutrient absorption occur in the small intestine but most of the intestinal water absorption observed by the large intestine.
34, a, Allow instillation of fluids into the stomach while leaving the other lumen plugged.
Blue pigtail of a double-lumen or Salem sump tube used for suction and irrigation of the stomach. one lumen used for suction the gastric content and another lumen used as an air vent.
35, c, Take an X-ray
Tube placement is verified by X-ray after insertion for the correct placement in the upper esophagus down to below the diaphragm. measuring the length of the tube from the nose will provide incorrect results because some time tube coiled up in the pharynx. Another method by aspirating a small amount of gastric content and check PH can be identified if the tube misplaced into the respiratory tract. although immediate action taken once the tube inserted is X-ray to confirm NG tube placement.
