Correct Answer: B

Rationale: Cigarette smoking should be avoided because of its stimulatory effect on gastric secretions. Nicotine also increases the release of epinephrine, which leads to vasoconstriction. The client may chew gum if desired. The client may eat chocolate if desired. A client with a peptic ulcer should check with the physician before taking any over-the-counter drug, but acetaminophen does not typically cause gastric irritation.

Correct Answer: D

Rationale: Intestinal tubes are not irrigated. Injecting air into the tube, applying water-soluble lubricant, and coiling extra tubing are appropriate nursing measures.

Correct Answer: A

Rationale: Because celiac disease destroys the absorbing surface of the intestine, fat isn't absorbed but is passed in the stool. Steatorrhea is bulky, fatty stools that have a foul odor. Jaundiced sclerae result from elevated bilirubin levels. Clay-colored stools are seen with biliary disease when bile flow is blocked. Celiac disease doesn't cause a widened pulse pressure.

Correct Answer: B

Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.

Correct Answer: C

Rationale: The gallbladder receives bile from the liver through the cystic duct. The liver collects bile in the canaliculi. Bile then flows into the common hepatic duct. From the common hepatic duct, the bile can be stored in the gallbladder through the cystic duct. Otherwise, the bile can flow directly into the duodenum by way of the common bile duct.
