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

Nasogastric feeding tube placement is the most appropriate choice for patients expected to be on a tube feeding for less than four weeks since it is a temporary solution that can be easily inserted and removed. Gastrostomy, jejunostomy, duodenostomy, and nasoduodenal are more invasive and are usually reserved for long-term tube feeding solutions.

Question 2

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 3

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 4

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

Accepted Answer

Elemental formulas contain predigested nutrients and have a high osmolality due to their small molecule size, making them the type of enteral formula with the highest osmolality.

Question 5

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.

Question 6

The advantages of a closed feeding system include _____.​

Accepted Answer

Closed feeding systems are designed to minimize the risk of microbial contamination. Since the system is not open to the environment, there is less chance of contamination from external sources. This is particularly important in critical care settings where patients may be at risk of infection.

Question 7

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

Accepted Answer

Heart disease does not typically increase a patient's water requirements, unlike severe vomiting, fever, blood loss, and diarrhea.

Question 8

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 9

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 as the feeding can be inhaled into the lungs, causing aspiration pneumonia or other respiratory problems.

Question 10

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

Accepted Answer

The answer of Enteral formulas may be used orally to...

Question 11

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 that are broken down into their simplest forms, making them easier to digest and absorb. This would be the best choice for a patient with impaired ability to digest and absorb food. The other options may not be sufficient for meeting the patient's nutrient needs or may not be easily tolerated by the patient.

Question 12

To ensure that the stomach is emptying properly, the nurse may measure _____.​

Accepted Answer

Measuring gastric residual volume is the best way to ensure that the stomach is emptying properly. It involves aspirating the contents of the stomach through a nasogastric or gastrostomy tube and measuring the volume. If the residual volume is high, it may indicate delayed gastric emptying, which could lead to complications such as aspiration. Monitoring feeding tube residual volume, body weight after feeding, urine output, and gastric emptying rate may also be useful, but they are not as reliable as measuring gastric residual volume.

Question 13

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

Accepted Answer

The procedure described in the question is gastric decompression, in which stomach contents are removed by suction. Therefore, choice A is the correct answer. Choice B (enterostomy) does not describe the process of removing stomach contents by suction. Choice C (gastric residuals) refers to the amount of food remaining in the stomach after digestion, but does not involve suction. Choice D (aspiration) refers to the accidental inhalation of fluids or food particles into the lungs, which is not the same as intentionally removing stomach contents by suction. Choice E (duodenal compression) does not describe the process of removing stomach contents by suction.

Question 14

An ideal formula for a patient is one that _____.​

Accepted Answer

An ideal formula for a patient should meet his/her medical and nutrient needs, ensuring adequate intake of all necessary macronutrients, micronutrients, and other essential components to promote health and recovery. While cost, fiber content, lactose, and ease of administration may also be important factors to consider, they should not take priority over meeting the patient's medical and nutrient needs.

Question 15

The outer diameter of a feeding tube is measured in _____.​

Accepted Answer

The outer diameter of a feeding tube is typically measured in French units, which are a system of measuring based on the circumference of a circle. One French unit is equal to 0.33 millimeters, so a tube with a diameter of 12 French has an outer diameter of approximately 4 millimeters. Millimeters (A) and milliliters (C) are units of measurement for length and volume, respectively, and are not typically used to measure the outer diameter of a feeding tube. English units (D) and standard units (E) are vague terms that do not refer to a specific system of measurement.

Question 16

Which statement does not describe feeding tubes?​

Accepted Answer

Feeding tubes do not all have the same diameter. Different types of feeding tubes have different diameters depending on their purpose and the needs of the patient. For example, a larger diameter tube may be needed for patients who require thicker formulas or for those with a history of clogging the tube.

Question 17

To prevent bacterial contamination during tube feedings, care givers must follow all of these recommendations except ____.

Accepted Answer

All of the other options are recommended to prevent bacterial contamination during tube feedings. However, fresh formula should be used every 24 hours rather than every 48 hours to reduce the risk of bacterial growth.

Question 18

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

Accepted Answer

The answer of An adult's daily water requirement is about...
