Question 1

To ensure a patient who is receiving TPN is adapting to the solution, health care professionals monitor

Accepted Answer

Healthcare professionals monitor electrolyte balance and blood glucose concentration to ensure a patient is adapting to TPN, as these are critical indicators of metabolic stability and nutritional adequacy. Arterial blood gases are not typically monitored for TPN adaptation.

Question 2

Which of the following does not need to be monitored daily for a client receiving TPN?

Accepted Answer

Liver enzymes do not need to be monitored daily for a client receiving TPN. They are typically monitored periodically unless there is a specific concern.

Question 3

Which statement is false?

Accepted Answer

To "piggyback" means to administer a second solution through the same catheter, not a second catheter.

Question 4

Suppose a person is receiving 2000 milliliters of a 10% amino acid solution.What is the amount of amino acids provided?

Accepted Answer

A 10% solution means there are 10 grams of amino acids per 100 milliliters. Therefore, in 2000 milliliters, there are 200 grams of amino acids (10 grams/100 ml * 2000 ml = 200 grams).

Question 5

How many kcalories are provided by 3 liters of a 5% dextrose solution?.

Accepted Answer

1 liter of 5% dextrose solution provides 170 kcalories. Therefore, 3 liters of 5% dextrose solution provides 3 x 170 = 510 kcalories.

Question 6

Which of the following measurements should be taken daily for a client receiving TPN?

Accepted Answer

Monitoring weight daily helps assess fluid balance and nutritional status in clients receiving Total Parenteral Nutrition (TPN).

Question 7

A person on cyclic parenteral nutrition receives an infusion at a constant rate for

Accepted Answer

Cyclic parenteral nutrition typically involves infusing nutrients over a period of 8 to 16 hours per day, allowing the patient to have a break from the infusion for the remaining hours.

Question 8

Which type of parenteral nutrition is provided at night so patients can participate in routine activities during the day?

Accepted Answer

Cyclic parenteral nutrition is administered over a shorter period, typically at night, allowing patients to engage in daily activities without being connected to an infusion pump during the day.

Question 9

To prevent bacterial contamination and maintain stability, parenteral solutions are:

Accepted Answer

Parenteral solutions are compounded in the pharmacy under strict aseptic conditions to prevent contamination. Warmed to room temperature prior to infusion may prevent some adverse reactions, but it will not prevent bacterial contamination. Exposing parenteral solutions to light can cause degradation of certain components, but it will not prevent bacterial contamination. Pasteurization is a process used to kill bacteria in food items, but it is not used for parenteral solutions.

Question 10

The health care team has just ordered Mr.Carter to begin TPN.He is a 58-year-old man who is suffering from intractable diarrhea.Before Mr.Carter starts TPN, what procedure should be performed?

Accepted Answer

An X-ray is necessary to confirm the correct placement of the catheter before starting Total Parenteral Nutrition (TPN) to ensure safe administration and prevent complications.

Question 11

Which of the following is a possible catheter-related complication in parenteral nutrition?

Accepted Answer

Catheter-related complications in parenteral nutrition include phlebitis and air embolism.

Question 12

A(n) _____ is made up of physicians, nurses, dietitians, and pharmacists.

Accepted Answer

A nutrition support team is composed of healthcare professionals like physicians, nurses, dietitians, and pharmacists who work together to provide nutritional care and support to patients.

Question 13

The benefits of cyclic infusion of TPN include

Accepted Answer

Cyclic infusion of TPN allows for flexibility in the daily scheduling of activities, as it can be infused over a shorter period of time (usually 10-14 hours) and then stopped during the day. This may allow the individual to participate in more normal eating and activity patterns while still receiving adequate nutrition. A and B are incorrect as maintenance of high insulin levels and increase in fat stores may not necessarily be desired outcomes, and D is incorrect as a negative nitrogen balance indicates a loss of protein and is not a desirable outcome.

Question 14

How much dextrose would a person receive from 2000 milliliters of 50% dextrose?

Accepted Answer

A 50% dextrose solution means there are 50 grams of dextrose per 100 milliliters. Therefore, in 2000 milliliters, there would be 1000 grams of dextrose (50 grams/100 mL * 2000 mL = 1000 grams).

Question 15

If a TPN solution contains 80 grams of amino acids per 1 L solution, what is the contribution of these amino acids to the osmolarity of the TPN?

Accepted Answer

The answer of If a TPN solution contains 80 grams...

Question 16

How many grams of amino acids would be provided to a client receiving 2,000 mL of a 5% amino acid solution?

Accepted Answer

The answer of How many grams of amino acids would...

Question 17

The health care team has just ordered Mr.Carter to begin TPN.He is a 58-year-old man who is suffering from intractable diarrhea.On a weekly basis, the health care team should perform what part of the nutrition care process?

Accepted Answer

The health care team should assess Mr. Carter's nutrition status on a weekly basis to monitor his response to TPN and adjust the nutrition care plan as needed.

Question 18

Which of the following would be the best method of delivery of long-term TPN to a 14 year old?

Accepted Answer

Cyclic infusion is often preferred for long-term TPN in adolescents as it allows for more normal daily activities and reduces the risk of liver complications associated with continuous TPN.

Question 19

Which vitamin is omitted from parenteral solutions designed for patients on warfarin therapy?

Accepted Answer

Vitamin K is omitted from parenteral solutions for patients on warfarin therapy because it can counteract the anticoagulant effects of warfarin.
