(Chapter 44) Digestive and GI Treatment Modalities
As part of the process of checking the placement of a nasogastric tube, the nurse checks the pH of the aspirate. Which pH finding would indicate to the nurse that the tube is in the stomach?
4 Explanation: Gastric secretions are acidic and have a pH ranging from 1 to 5. Intestinal aspirate is typically 6 or higher; respiratory aspirate is more alkaline, usually 7 or greater. pg.1218
The nurse is inserting a nasogastric tube for a patient with pancreatitis. What intervention can the nurse provide to allow facilitation of the tube insertion?
Allow the patient to sip water as the tube is being inserted.
The nurse is to discontinue a nasogastric tube that had been used for decompression. The first thing the nurse does is
Flush with 10 mL of water. Explanation: Before a nasogastric tube is removed, the nurse flushes the tube with 10 mL of water or normal saline to ensure that the tube is free of debris and away from the gastric tissue. The tape keeps the tube in the correct position while flushing is occurring and is then removed from the nose. The nurse then withdraws the tube gently for 6 to 8 inches until the tip reaches the esophagus, and then the remainder of the tube is withdrawn rapidly from the nostril. After the tube is removed, the nurse provides oral hygiene. pg.1219
A client recovering from gastric bypass surgery accidentally removes the nasogastric tube. It is best for the nurse to
Notify the surgeon about the tube's removal. Explanation: If the nasogastric tube is removed accidently in a client who has undergone esophageal or gastric surgery, it is usually replaced by the physician. Care is taken to avoid trauma to the suture line. The nurse will not insert the tube to the esophagus or to the stomach in this situation. The nurse needs to do more than just document its removal. The nurse needs to notify the physician who will make a determination of leaving out or inserting a new nasogastric tube. pg.1219
Which condition is caused by improper catheter placement and inadvertent puncture of the pleura?
Pneumothorax A pneumothorax is caused by improper catheter placement and inadvertent puncture of the pleura. Air embolism can occur from a missing cap on a port. Sepsis can be caused by the separation of dressings. Fluid overload is caused by fluids infusing too rapidly.
The nurse is inserting a Levin tube for a patient for gastric decompression. The tube should be inserted to 6 to 10 cm beyond what length?
The distance measured from the tip of the nose to the earlobe and from the earlobe to the xiphoid process
The client cannot tolerate oral feedings due to an intestinal obstruction and is NPO. A central line has been inserted, and the client is being started on parenteral nutrition (PN). The nurse performs the following actions while the client receives PN (select all that apply):
b) Weigh the client every day. e) Check blood glucose level every 6 hours. c) Document intake and output. Explanation: When a client is receiving PN through a central line, the nurse weighs the client daily, checks blood glucose level every 6 hours, and documents intake and output. These actions are to ensure the client is receiving optimal nutrition. The nurse also performs activities to prevent infection, such as covering the insertion site with a transparent dressing that is changed weekly and/or prn and using sterile technique during catheter site dressing changes. pg.1228
The client is experiencing swallowing difficulties and is now scheduled to receive a gastric feeding. She has the following oral medications prescribed: furosemide (Lasix), digoxin, enteric coated aspirin (Ecotrin), and vitamin E. The nurse withholds....
enteric coated aspirin Simple compressed tablets (furosemide, digoxin) may be crushed and dissolved in water. Soft gelatin capsules filled with liquid (vitamin E) may be opened, and the contents squeezed out. Enteric coated tablets (enteric coated aspirin) are not to be crushed and a change in the form of the medications is required. (less)
The client is on a continuous tube feeding. The nurse determines the tube placement should be checked every
shift Explanation: Each nurse caring for the client is responsible for verifying that the tube is located in the proper area for continuous feeding. Checking for placement each hour is unnecessary unless the client is extremely restless or there is basis for rechecking the tube due to other client activities. Checking for placement every 12 or 24 hours does not meet the standard of care for the client receiving continuous tube feedings.
The nurse is caring for a patient who has dumping syndrome from high carbohydrate foods being administered over a period of less than 20 minutes. What is a nursing measure to prevent or minimize the dumping syndrome?
Administer the feeding with the patient in semi-Fowler's position to decrease transit time influenced by gravity
To ensure patency of central venous line ports, diluted heparin flushes are used
Daily when not in use Explanation: Daily instillation of dilute heparin flush when a port is not in use will maintain the port. Continuous infusion maintains the patency of each port. Heparin flushes are used after each intermittent infusion. Heparin flushes are used after blood drawing in order to prevent clotting of blood within the port. Heparin flush of ports is not necessary if a line is to be discontinued. pg.1231
The nurse prepares to administer all of a client's medications via feeding tube. The nurse consults the pharmacist and/or physician when the nurse notes which type of oral medication on the client's medication administration record?
Enteric-coated tablets- Enteric-coated tablets are meant to be digested in the intestinal tract and may be destroyed by stomach acids. A change in the form of medication is necessary for patients with tube feedings. Simple compressed tablets may be crushed and dissolved in water for patients receiving oral medications by feeding tube. Buccal or sublingual tablets are absorbed by mucous membranes and may be given as intended to the patient undergoing tube feedings. The nurse may make an opening in the capsule and squeeze out contents for administration.
The nurse conducts discharge education for a client who is to go home with parenteral nutrition (PN). The nurse determines the client understands the education when the client indicates a sign and/or symptom of metabolic complications is
Loose, watery stools When the patient indicates that loose watery stools are a sign/symptom of metabolic complications, the nurse evaluates that the patient understands the teaching of metabolic complications. Signs and symptoms of metabolic complications from PN include neuropathies, mentation changes, diarrhea, nausea, skin changes, and decreased urine output.
Before inserting a gastric or enteric tube, the nurse determines the length of tubing that will be needed to reach the stomach or small intestine. The Levin tube, a commonly used nasogastric tube, has circular markings at specific points. This tube should be inserted to 6 to 10 cm beyond what length?
The distance measured from the tip of the nose (N) to the earlobe (E) and from the earlobe to the xiphoid (X) process
A client who can't tolerate oral feedings begins receiving intermittent enteral feedings. When monitoring for evidence of intolerance to these feedings, the nurse must remain alert for:
diaphoresis, vomiting, and diarrhea Explanation: The nurse must monitor for diaphoresis, vomiting, and diarrhea because these signs suggest an intolerance to the ordered enteral feeding solution. Other signs and symptoms of feeding intolerance include abdominal cramps, nausea, aspiration, and glycosuria. Electrolyte disturbances, constipation, dehydration, and hypercapnia are complications of enteral feedings, not signs of intolerance. Hyperglycemia, not hypoglycemia, is a potential complication of enteral feedings. pg.1223
The most significant complication related to continuous tube feedings is
the increased potential for aspiration.
The most significant complication related to continuous tube feedings is
The potential for aspiration Explanation: Because the normal swallowing mechanism is bypassed, consideration of the danger of aspiration must be foremost in the mind of the nurse caring for the patient receiving continuous tube feedings. Tube feedings preserve GI integrity by intraluminal delivery of nutrients. Tube feedings preserve the normal sequence of intestinal and hepatic metabolism. Tube feedings maintain fat metabolism and lipoprotein synthesis. pg.1219
As part of the process of checking the placement of a nasogastric tube, the nurse checks the pH of the aspirate. Which pH finding would indicate to the nurse that the tube is in the stomach?
4 Explanation: Gastric secretions are acidic and have a pH ranging from 1 to 5. Intestinal aspirate is typically 6 or higher; respiratory aspirate is more alkaline, usually 7 or greater. pg.1218
A client with a gastrojejunostomy is beginning to take solid food. Which finding would lead the nurse to suspect that the client is experiencing dumping syndrome?
Diarrhea Clients with a gastrojejunostomy are at risk for developing the dumping syndrome when they begin to take solid food. This syndrome produces weakness, dizziness, sweating, palpitations, abdominal cramps, and diarrhea, which result from the rapid emptying (dumping) of large amounts of hypertonic chyme (a liquid mass of partly digested food) into the jejunum. This concentrated solution in the gut draws fluid from the circulating blood into the intestine, causing hypovolemia. The drop in blood pressure can produce syncope. As the syndrome progresses, the sudden appearance of carbohydrates in the jejunum stimulates the pancreas to secrete excessive amounts of insulin, which in turn causes hypoglycemia.
The physician orders the insertion of a single lumen nasogastric tube. When gathering the equipment for the insertion, the nurse would select which of the following?
Levin tube Explanation: A Levin tube is a single lumen nasogastric tube. A Salem sump tube is a double lumen nasogastric tube; a Sengsten-Blakemore tube is a triple lumen nasogastric tube. A Miller-Abbott tube is a double lumen nasoenteric tube. pg.1215
