Child with short bowel syndrome Middle-aged man with acute pancreatitis Man with two-thirds of his colon removed
A nurse is caring for a patient receiving parenteral nutrition at home. The patient was discharged from the acute care facility 4 days ago. Which of the following would the nurse include in the patient's plan of care? Select all that apply.
Daily weights Intake and output monitoring Calorie counts for oral nutrients
The nurse is caring for a comatose patient and administering gastrostomy feedings. What does the nurse understand is the reason that gastrostomy feedings are preferred to nasogastric (NG) feedings in the comatose patient?
Gastroesophageal sphincter is intact, lessening the possibility of regurgitation.
A patient is receiving parenteral nutrition. The current solution is nearing completion, and a new solution is to be hung, but it has not arrived from the pharmacy. Which action by the nurse would be most appropriate?
Hang a solution of dextrose 10% and water until the new solution is available.
The client is receiving a 25% dextrose solution of parenteral nutrition. The infusion machine is beeping, and the nurse determines the intravenous (IV) bag is empty. The nurse finds there is no available bag to administer. It is most important for the nurse to
Infuse a solution containing 10% dextrose and water. Explanation: If the parenteral nutrition solution runs out, a solution of 10% dextrose and water is infused to prevent hypoglycemia. The nurse would then order the next parenteral nutrition bag from the pharmacy. Flushing a peripherally inserted catheter is usually prescribed every 8 hours or per hospital established protocols. It is not the most important activity at this moment. The infusion rate should not be increased to compensate for fluids that were not infused, because hyperglycemia and hyperosmolar diuresis could occur.
The nurse is managing a gastric (Salem) sump tube for a patient who has an intestinal obstruction and will be going to surgery. What interventions should the nurse perform to make sure the tube is functioning properly?
Keep the vent lumen above the patient's waist to prevent gastric content reflux.
A patient receiving tube feedings has prescriptions for several drugs. Which of the following drugs would the nurse expect to administer to the patient without any special preparation? Select all that apply.
Liquid stool softener Sublingual nitroglycerin Explanation: Liquid medications do not require any special preparation for administration via a feeding tube. Buccal or sublingual tablets are administered as prescribed. They are absorbed through the mucosa of the cheek or under the tongue and thus would not be administered through the feeding tube. Enteric-coated aspirin and sustained-release antihypertensive could not be given as is through a feeding tube. A change in formulation would be needed. An acetaminophen tablet would need to be crushed and dissolved in water before being given.
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.

The nurse has developed a care plan for the nursing diagnosis "Risk for infection related to contamination of the central catheter site or infusion line." The nurse includes the intervention
Wear a face mask during dressing changes.
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):
Weigh the client every day. Check blood glucose level every 6 hours. Document intake and output.
The dumping syndrome occurs when high-carbohydrate foods are administered over a period of less than 20 minutes. A nursing measure to prevent or minimize the dumping syndrome is to administer feedings:
With the patient in semi-Fowler's position to decrease transit time influenced by gravity.
The most significant complication related to continuous tube feedings is
the increased potential for aspiration
Which condition is caused by improper catheter placement and inadvertent puncture of the pleura?
pneumothorax
The nurse administers a tube feeding to a client via the intermittent gravity drip method. The nurse should administer the feeding over at least which period of time?
30 minutes
A client is receiving continuous tube feedings at 75 mL/hr. The nurse has checked the residual volume 4 hours ago as 250 mL. The nurse now assesses the residual volume as 325 mL. The first action of the nurse is to
Notify the physician
The nurse cares for a client who receives parenteral nutrition (PN). The nurse notes on the care plan that the catheter will need to be removed 6 weeks after insertion and that the client's venous access device is a
nontunneled central catheter. Explanation: Nontunneled central catheters are used for short-term (less than 6 weeks) IV therapy in acute care settings. The subclavian vein is the most common vessel used because the subclavian area provides a stable insertion site to which the catheter can be anchored; it allows the client freedom of movement and provides easy access to the dressing site. Peripherally inserted central catheter (PICC) lines may be used for intermediate terms (3 to 12 months). Tunneled central catheters are for long-term use and may remain in place for many years. Implanted ports are devices also used for long-term home IV therapy (e.g., Port-A-Cath, Mediport, Hickman Port, P.A.S. Port).
A patient has had a gastrostomy tube inserted. What does the nurse anticipate the initial fluid nourishment will be after the insertion of the gastrostomy tube?
10% glucose and tap water
A patient is receiving a continuous tube feeding. The nurse notes that the feeding tube was last irrigated at 2 p.m. The nurse would plan to irrigate the tube again at which time?
6 p.m. to 8 p.m.
The nurse is to insert a postpyloric feeding tube. One way that the nurse can aid in placement past the pylorus is to
Administer prescribed metoclopramide (Reglan).
The client has just had a central line inserted for parenteral nutrition. The client is awaiting transport to the Radiology Department for catheter placement verification. The client reports feeling anxious. Respirations are 28 breaths/minute. The first action of the nurse is
Auscultate lung sounds
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.
A patient is receiving nasogastric tube feedings. The intake and output record for the past 24 hours reveals an intake of 3100 mL and an output of 2400 mL. The nurse identifies which nursing diagnosis as most likely?
Excess fluid volume
A nurse is preparing to perform a dressing change to the site of a patient's central venous catheter used for parenteral nutrition. Which equipment and supplies would the nurse need to gather? Select all that apply.
Masks Skin antiseptic Alcohol wipes Sterile gauze pads
The nurse confirms placement of a client's nasogastric (NG) tube using a combination of visual and pH assessment of the aspirate. The nurse determines that the NG tube remains properly placed when the pH of the aspirate is
acidic
The primary source of microorganisms for catheter-related infections are the skin and the
catheter hub
The nurse attempts to unclog a client's feeding tube. Attempts with warm water agitation and milking the tube are unsuccessful. The nurse uses evidence-based practice principles when subsequently using which technqiue to unclog the tube?
digestive enzymes and sodium bicarbonate Explanation: The nurse should attempt to unclog the tube with digestive enzymes activated with sodium bicarbonate. Although historically both cranberry juice and cola have sometimes been used to unclog feeding tubes, evidence has shown that their acidic nature worsens the clog by causing precipitation of proteins. Meat tenderize diluted with saline is not applicable.
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.
Which venous access device can be used for less than 6 weeks in clients requiring parenteral nutrition?
nontunneled catheters
