Question 1

A formula with an osmolality greater than that of blood serum is known as a(n)____ formula . ​

Accepted Answer

A formula with an osmolality greater than that of blood serum is known as a hypertonic formula.

Question 2

What can happen when medications are infused along with enteral feedings?

Accepted Answer

Infusing medications along with enteral feedings can increase the osmotic load and contribute to diarrhea. It is important to consider the compatibility of medications with enteral feeding formulas and to administer medications separately if possible. Monitoring for signs of diarrhea and electrolyte imbalances is also crucial. Options B, C, and D are not accurate.

Question 3

A health care provider is preparing to administer a tube feeding to a patient with a nasogastric tube. To best reduce the risk of formula contamination, the caregiver should perform which step first? ​

Accepted Answer

The first step to reduce the risk of formula contamination should be to clean the lid of the can with an alcohol wipe to remove any potential pathogens. Warming the can in a pan of hot water or pouring the contents into a clean container can be done after ensuring the lid is cleaned to prevent any contamination. Labeling the can with the date and time of its opening is important for tracking purposes but does not directly reduce the risk of formula contamination.

Question 4

A respiratory secretion sample typically  has a pH of ____. ​

Accepted Answer

The normal pH of respiratory secretion is around 6. If the pH is below 6, it may indicate the presence of acid-fast bacteria or other pathogens. A pH of 3 or lower may indicate gastric reflux or aspiration of stomach contents into the lungs. A pH of 4 or 5 may also indicate an infection or inflammation in the respiratory tract.

Question 5

The delivery of up to 500 mL of formula within 10 minutes is termed a(n)____. ​

Accepted Answer

Bolus feeding involves the delivery of a large volume of formula (usually 250-500 mL) over a short period of time (usually 10-20 minutes) and is often used for patients who are unable to tolerate continuous feedings or require a more aggressive approach to meet their nutritional needs. Minimal residual feeding involves the continuous drip of very small amounts of formula, intermittent feeding involves the delivery of formula in small, frequent doses, and a continuous drip involves a slow and steady rate of infusion over an extended period of time.

Question 6

Most enteral formulas have energy density of ____ kcalories per milliliter of fluid. ​

Accepted Answer

Most enteral formulas are designed to provide 1.0 to 2.0 kilocalories per milliliter of fluid, catering to standard nutritional needs and making them suitable for a wide range of patients requiring tube feeding.

Question 7

What is a characteristic of an open feeding system?

Accepted Answer

In an open feeding system, the formula must be transferred from its original container to the feeding container, which is a defining characteristic of this system.

Question 8

The vast majority of patients use which type of enteral formula? ​

Accepted Answer

According to the question, the vast majority of patients use standard enteral formula. Therefore, the best choice is A) standard.

Question 9

A patient with fluid, electrolyte, and protein restrictions would most likely need which type of formula? ​

Accepted Answer

A patient with fluid, electrolyte, and protein restrictions would most likely need a renal or hepatic insufficiency formula. These formulas are designed to provide adequate nutrition while limiting excessive electrolytes, fluids, and proteins.

Question 10

What is a carbohydrate source used in many standard formulas? ​

Accepted Answer

Maltodextrin is a commonly used carbohydrate source in standard formulas because it is relatively tasteless, easily digestible, and helps to promote a steady release of glucose into the bloodstream. Aldose and amylopectin are not typically used as carbohydrate sources in formulas, and cellulose is not a digestible carbohydrate.

Question 11

To reduce the risk of aspiration, the patient's upper body is elevated to a ____ degree angle during the feeding.

Accepted Answer

Elevating the patient's upper body to a 30 to 45 degree angle during feeding can help reduce the risk of aspiration by preventing food or liquid from entering the trachea. This position helps to promote safer swallowing and reduce the risk of choking or respiratory distress. Lower angles such as 5-10 degrees or 15-30 degrees may not provide sufficient protection, while higher angles such as 45-60 degrees may be uncomfortable or impractical for some patients.

Question 12

Open containers of formula that are unused should be disposed of within ____ hours. ​

Accepted Answer

The answer of Open containers of formula that are unused...

Question 13

A fasting gastric secretion sample typically has a pH of ____. ​

Accepted Answer

A fasting gastric secretion sample typically has a pH of 5 or lower due to the presence of hydrochloric acid in the stomach.

Question 14

What is a characteristic of a closed feeding system?

Accepted Answer

A closed feeding system allows for the formula to hang for a longer period of time without risk of contamination, making it a convenient option for patients who require continuous feeding.

Question 15

Intermittent tube feedings are best tolerated when they are administered over ____. ​

Accepted Answer

Intermittent tube feedings are best tolerated when they are administered over 30 to 45 minutes. This allows for a slower and more gradual delivery of the feed, reducing the chances of discomfort or complications. Administering the feeding too quickly (options A and C) may lead to nausea, vomiting, or diarrhea, while spacing out the feedings too much (option D) may not provide sufficient nutrition. Therefore, option B is the best choice for administering intermittent tube feedings.

Question 16

Proper sterile techniques should be used during preparation and delivery of formulas to protect patients from ____. ​

Accepted Answer

Proper sterile techniques are important in avoiding exposure to foodborne illnesses during the preparation and delivery of formulas. This helps to protect patients who are often already immunocompromised from additional infection.

Question 17

Health care facilities have protocols for handling food products and formulas based on the potential hazards and critical control points in food preparation, which are called ____. ​

Accepted Answer

HACCP (Hazard Analysis and Critical Control Points) systems are a set of guidelines designed to ensure food safety in healthcare facilities by identifying potential hazards and implementing critical control points in food preparation. The Joint Commission mandates and AHA (American Heart Association) standards may also be relevant in healthcare facilities, but they do not specifically address food preparation and safety. MSDS (Material Safety Data Sheet) requirements are related to the safety of chemical products, not food products.

Question 18

Iris has an order for continuous tube feedings through her nasogastric tube. She is to receive 2500 mL of formula on a continuous basis over 24 hours. What hourly rate should the healthcare provider set the pump at? ​

Accepted Answer

To calculate the hourly rate, divide the total volume (2500 mL) by the number of hours (24). This equals approximately 104 mL per hour.

Question 19

Intermittent feeding using the gravity drip is suitable for the delivery of no more than how much formula over 30 minutes?

Accepted Answer

The answer of Intermittent feeding using the gravity drip is...

Question 20

When an open feeding system is used, the nurse should hang no more than a(n)____ hour supply. ​

Accepted Answer

In an open feeding system, it's recommended to hang no more than an 8-hour supply to minimize the risk of bacterial growth and ensure the freshness of the feed.
