A nurse is providing discharge teaching to a client who will be receiving total parenteral nutrition (TPN) at home.
Which of the following instructions should the nurse include? (Select all that apply.)
Infuse 10 percent dextrose and water if the solution runs out.
Shake the TPN bag with fat emulsion if precipitate is present.
Maintain TPN infusion rate when behind schedule.
Keep the TPN refrigerated when not in use.
Correct Answer : A,D
Choice A rationale
Infusing 10 percent dextrose and water prevents hypoglycemia if TPN is temporarily unavailable. This is a crucial step in maintaining the patient's blood sugar levels.
Choice B rationale
Shaking the TPN bag with fat emulsion can cause the emulsion to break, leading to potential complications. Fat emulsions should be mixed gently.
Choice C rationale
Maintaining the TPN infusion rate when behind schedule is incorrect as it can lead to rapid infusion and complications such as hyperglycemia and fluid overload.
Choice D rationale
Keeping the TPN refrigerated when not in use helps to maintain its stability and prevent bacterial contamination. Proper storage is essential for patient safety. .

Correct Answer is A
Explanation
Choice A rationale
The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygenation of central tissues. When there is a lack of oxygen in the bloodstream, the lips and mucous membranes, such as the oral mucosa, appear blue or cyanotic. This is a clear sign that the central tissues are not receiving adequate oxygenation.
Choice B rationale
The sclera of the eye is not a reliable indicator of central cyanosis. The sclera is white and does not change color due to oxygen levels. Instead, it may become yellow in jaundice or red in inflammation but does not reflect central cyanosis.
Choice C rationale
The ear lobes are peripheral areas and do not reliably indicate central cyanosis. Peripheral cyanosis can occur due to local blood flow issues, and ear lobes can appear blue in cold conditions even when central oxygenation is normal.
Choice D rationale
The soles of the feet, similar to the ear lobes, are peripheral areas and not reliable indicators of central cyanosis. Cyanosis in the feet can result from poor peripheral circulation rather than central hypoxia.
Correct Answer is B
Explanation
Choice A rationale
Notifying the healthcare provider is necessary, but assessing the client's condition comes first to provide relevant information.
Choice B rationale
Assessing the client's vital signs and telemetry monitor is the first step to determine the cause of chest pain and ensure it is not due to a life-threatening issue such as myocardial infarction.
Choice C rationale
Encouraging the client to take deep breaths can be helpful but is not the first priority. It addresses pain related to breathing but not the underlying cause.
Choice D rationale
Administering pain medication is important, but only after determining the cause of the chest pain and ruling out serious complications.
