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).

A nurse is preparing to assist a physician with a peripherally inserted central catheter. The nurse demonstrates understanding of this procedure by preparing which insertion site?

Basilic vein

The primary source of microorganisms for catheter-related infections are the skin and which of the following?

Catheter hub

Nursing students are reviewing information about parenteral nutrition and indications for use. They demonstrate understanding of the material when they identify which patients as appropriate candidates for parenteral nutrition? Select all that apply.

Child with short bowel syndrome Middle-aged man with acute pancreatitis Man with two-thirds of his colon removed

A client has a nasogastric tube for continuous tube feeding. The nurse does all the following every shift to verify placement (select all options that apply):

Compares exposed tube length with original measurement Visually assesses the color of the aspirate Checks the pH of the gastric contents

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

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

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.

A client is receiving parenteral nutrition (PN) through a peripherally inserted central catheter (PICC) and will be discharged home with PN. The home health nurse evaluates the home setting and makes a recommendation when noting the following:

No land line; cell phone available and taken by family member during working hours

10% glucose and tap water

The client has the intake and output shown in the accompanying chart for an 8-hour shift. What is the positive fluid balance?

260

A patient has a gastric sump tube attached to low intermittent suction. The nurse empties the suction collection chamber and records an output of 320 mL for this 8-hour shift. The record shows that the tube had been irrigated with 20 mL of normal saline twice this shift. What would be the actual output of the gastric sump tube?

280

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.

Which tube is a nasoenteric feeding tube?

Dobhoff

The nurse is to administer a cyclic feeding through a gastric tube. It is most important for the nurse to

Elevate the head of the bed to 45 degrees.

A client is scheduled to receive a 25% dextrose solution of parenteral nutrition. The nurse does all of the following. Select all that apply.

Ensures availability of an infusion pump Ensures completion of baseline monitoring of the complete blood count (CBC) and chemistry panel Places a 1.5-micron filter on the tubing

When assessing whether a patient is a candidate for home parenteral nutrition, which of the following would be important to address? Select all that apply.

Family support Telephone access Motivation for learning Health status

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.

Gastrostomy feedings are preferred to nasogastric feedings in the comatose patient, because the:

Gastroesophageal sphincter is intact, lessening the possibility of regurgitation and aspiration.

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.

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

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 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

A physician orders an intestinal tube to decompress a client's GI tract. When gathering equipment for this procedure, a nurse should obtain a:

Miller-Abbott tube.

The nurse cares for a client who receivies continuous enteral tube feedings and who is at low risk for aspiration. The nurse assesses the gastric residual volume to be 350 mL. The nurse determines which action is correct?

Monitoring the feeding closely

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

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.

A nurse suspects that a patient is developing rebound hypoglycemia secondary to parenteral nutrition being discontinued too rapidly. Which of the following would support the nurse's suspicions? Select all that apply.

Shakiness Tachycardia Weakness Confusion

A nurse is inserting a nasogastric tube for feeding a client. Place in order the steps from 1 to 6 for correctly inserting the tube.

Sit the client in an upright position Apply gloves to the nurse's hands Measure the length of the tube that will be inserted Apply water-soluble lubricant to the tip of the tube Tilt the client's nose upward Instruct the client to lower the head and swallow

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

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 nurse is inserting a sump tube in a patient with Crohn's disease who is suspected of having a bowel obstruction. What does the nurse understand is the benefit of the gastric (Salem) sump tube in comparison to some of the other tubes?

The tube is radiopaque.

When preparing to insert a nasogastric tube, the nurse determines the length of the tube to be inserted. The nurse nurse places the distal tip of the tube at which location?

Tip of patient's nose

The nurse is inserting a nasoenteric tube for a patient with a paralytic ileus. How long does the nurse anticipate the tube will be required? (Select all that apply.)

Until bowel sound is present Until flatus is passed Until peristalsis is resumed

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

A client receives tube feedings after an oral surgery. The nurse manages tube feedings to minimize the risk of aspiration. Which measure should the nurse include in the care plan to reduce the risk of aspiration?

Use semi-Fowler position during, and 60 minutes after, an intermittent feeding.

The client is receiving 50% dextrose parenteral nutrition with fat emulsion therapy through a peripherally inserted central catheter (PICC). 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 client is on a continuous tube feeding. The nurse determines the tube placement should be checked every

shift

The most significant complication related to continuous tube feedings is

the increased potential for aspiration

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

Hickman and Groshong are examples of which type of central venous access device?

tunneled central catheters

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

The primary source of microorganisms for catheter-related infections are the skin and the

catheter hub

What type of feedings should be administered to a client who is at risk of diarrhea due to hypertonic feeding solutions?

continuous feedings

The nurse collaborates with the physician and dietician to determine the best type of tube feeding for a client at risk for diarrhea due to hypertonic feeding solutions. Which type of feedings should the nurse suggest?

continuous feedings Continuous feedings should be administered to a client who is at risk of diarrhea due to hypertonic feeding solutions. Bolus or intermittent feedings cause sudden distention of the small intestine, and cyclic feedings are not advised.

To ensure patency of central venous line ports, diluted heparin flushes are used

daily when not in use

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.

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 recognizes that medium-length nasoenteric tubes are used for

feeding

Rebound hypoglycemia is a complication of parenteral nutrition caused by

feedings stopped too abruptly.

The nurse cares for a client who receives continuous parenteral nutrition (PN) through a Hickman catheter and notices that the client's solution has run out. No PN solution is currently available from the pharmacy. What should the nurse do?

hang 10% dextrose and water

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

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).

Which condition is caused by improper catheter placement and inadvertent puncture of the pleura?

pneumothorax
