Question 1

Which feeding tube placement site would be most appropriate for a patient who is expected to be on a tube feeding for less than four weeks? ​

Accepted Answer

For a patient who is expected to be on a tube feeding for less than four weeks, nasogastric tube placement would be the most appropriate. This type of feeding tube is inserted through the nose and goes down through the esophagus into the stomach. It is a temporary feeding tube option that can be easily removed when no longer needed. Gastrostomy, jejunostomy, duodenostomy, and nasoduodenal feeding tubes are all more permanent options and are typically used for patients who need long-term nutritional support.

Question 2

Aspirations associated with gastric feedings can lead to damage to the:

Accepted Answer

Aspirations associated with gastric feedings can lead to damage to the lungs. Aspiration occurs when food, liquid or saliva is inhaled into the lungs instead of being swallowed into the stomach. This can lead to a range of complications, including pneumonia and lung damage.

Question 3

To prevent bacterial contamination during tube feedings, care givers must follow all of these recommendations EXCEPT:

Accepted Answer

The recommendation of using fresh formula every 48 hours is incorrect as formula should be discarded after 24 hours to prevent bacterial growth and contamination.

Question 4

The outer diameter of a feeding tube is measured in:

Accepted Answer

French units are typically used to measure the outer diameter of feeding tubes. One French unit is equal to 0.33 millimeters.

Question 5

Enteral formulas may be used orally to supplement a patient's diet. When this occurs, _____ becomes an important consideration. ​

Accepted Answer

Taste becomes an important consideration when enteral formulas are used orally to supplement a patient's diet, as it affects the patient's willingness to consume the formula.

Question 6

An ideal formula for a patient is one that:

Accepted Answer

An ideal formula should meet the patient's medical and nutrient needs to ensure proper healing and recovery. The other options, such as cost, fiber content, lactose inclusion, or ease of administration, are important considerations but should not be the primary focus when deciding on the optimal formula for a patient's health.

Question 7

The appropriate placement site for tube feeding in an infant is:

Accepted Answer

The answer of The appropriate placement site for tube feeding...

Question 8

A "12 French" feeding tube has a diameter of:

Accepted Answer

French size is a measurement system used for medical tubes. It is based on the diameter of the tube in millimeters. One unit of French size is equivalent to 0.33 mm. Therefore, a "12 French" feeding tube has a diameter of 3.96 mm, which is closest to choice B of 4 mm.

Question 9

An adult's daily water requirement is about _____ milliliters of water per kg body weight.

Accepted Answer

An adult's daily water requirement is typically about 30-40 milliliters of water per kg body weight.

Question 10

Estimate the daily fluid needs of a 70-year-old female who weighs 110 pounds. ​

Accepted Answer

The general guideline for estimating daily fluid needs is about 30 mL per kg of body weight. Converting 110 pounds to kilograms (approximately 50 kg), the estimated fluid requirement would be around 1500 mL (50 kg x 30 mL/kg).

Question 11

Which type of enteral formula usually has the highest osmolality? ​

Accepted Answer

Elemental formulas typically have the highest osmolality because they contain pre-digested nutrients that are in their simplest, most easily absorbed form. This means that they require less digestion, resulting in a more concentrated formula with a higher osmolality.

Question 12

The advantages of a closed feeding system include:

Accepted Answer

A closed feeding system reduces the risk of contamination, as it minimizes exposure to external microbes and limits the potential for bacterial growth. This can help prevent infection and reduce the risk of digestive issues in patients receiving enteral feeding. The other options are not necessarily advantages of a closed feeding system. Lower initial cost, increased nurse contact, and increased patient tolerance may be important factors to consider when choosing a feeding system, but they do not specifically relate to closed systems. Less stress on the patient's digestive system may be a benefit of enteral feeding in general, but it is not necessarily unique to closed feeding systems.

Question 13

Which condition does not raise a patient's water requirements? ​

Accepted Answer

Heart disease does not raise a patient's water requirements.

Question 14

A procedure in which the stomach contents of a patient are removed by suction is called:

Accepted Answer

Gastric decompression involves removing stomach contents by suction, typically through a nasogastric or orogastric tube. The other options listed are not related to the removal of stomach contents.

Question 15

You are working with a patient whose ability to digest and absorb food is impaired, but whose nutrient needs are not elevated. Which formula would you select for this patient? ​

Accepted Answer

An elemental formula contains nutrients in their simplest form, which means that they are almost completely absorbed and do not require the same level of digestion as other formulas. This makes it the best choice for a patient with impaired digestion and absorption ability who does not have elevated nutrient needs.

Question 16

To minimize the risk of aspiration of formula in tube-fed patients, the head of the patient's bed should be elevated:

Accepted Answer

Elevating the head of the bed during and for 30 minutes after administration of the feeding has been shown to reduce the risk of aspiration in tube-fed patients by allowing gravity to help keep the formula in the stomach. Elevating the head of the bed for longer periods of time has not been shown to provide any further benefit.

Question 17

To ensure that the stomach is emptying properly, the nurse may measure:

Accepted Answer

Gastric residual volume is the amount of fluid left in the stomach after a feeding. Measuring gastric residual volume can help assess whether the stomach is emptying properly and can help prevent complications such as aspiration. Feeding tube residual volume is also measured, but this is more specific to patients with feeding tubes. Body weight after feeding and urine output are not related to assessing gastric emptying. Gastric emptying rate can be measured, but is not typically used in clinical practice to assess gastric emptying.

Question 18

A formula that approximates the osmolality of normal blood serum:

Accepted Answer

The formula that approximates the osmolality of normal blood serum is referred to as an isotonic formula. It is important for IV fluids to have an osmolality close to that of normal blood serum to prevent complications such as fluid overload or fluid depletion. Therefore, isotonic solutions are commonly used for intravenous therapy.

Question 19

Which statement does not describe feeding tubes? ​

Accepted Answer

Feeding tubes come in different diameters depending on the age and size of the patient, as well as the type of feeding being administered.

Question 20

Tube feedings are commonly used for individuals with:

Accepted Answer

Tube feedings are commonly used for individuals with severe swallowing difficulties, also known as dysphagia. Tube feedings bypass the oral and pharyngeal phases of swallowing and deliver nutrition directly into the stomach or small intestine. Tube feedings may also be used for individuals with nonfunctional GI tracts such as bowel obstruction or gastroparesis. While malabsorption disorders, pancreatitis, and intestinal blockages may all require specialized nutrition support, they may not necessarily be managed with tube feedings.
