A nurse is reviewing the laboratory values of a patient receiving total parenteral nutrition (TPN). The glucose is 72 mg/dL, chloride is 100 mEq/L, sodium is 138 mEq/L, and potassium is 3.0 mEq/L. What action should the nurse plan to take?
Administer glucagon IM.
Discontinue the TPN infusion.
Request a potassium replacement.
Check the patient for a positive Chvostek’s sign.
The Correct Answer is C
The correct answer is Choice C.
Step 1 is to interpret the laboratory values. The glucose level is within the normal range (7099 mg/dL). The chloride level is within the normal range (97-107 mEq/L). The sodium level is within the normal range (135-145 mEq/L). However, the potassium level is low (normal range is 3.5-5.0 mEq/L)89101112.
Step 2 is to plan the action based on the interpretation. Given the low potassium level, the nurse should plan to request a potassium replacement

Correct Answer is A
Explanation
Choice A rationale
Performing hand hygiene frequently and consistently is the most effective way to prevent the spread of pathogens during patient care. Hand hygiene is the single most important measure to reduce the transmission of harmful germs and prevent health care-associated infections.
Choice B rationale
Properly disposing of contaminated equipment is important in preventing the spread of pathogens, but it is not the most effective measure. While it is crucial to handle and dispose of contaminated equipment properly, hand hygiene is the most effective measure in preventing the spread of pathogens.
Choice C rationale
Discarding used syringes in appropriate containers is a standard safety measure in healthcare settings, but it is not the most effective way to prevent the spread of pathogens during patient care. While it is important for preventing needlestick injuries and the spread of bloodborne pathogens, hand hygiene is the most effective measure in preventing the spread of pathogens.
Choice D rationale
Changing soiled linens daily for patients with draining wounds is a part of standard wound care and infection control, but it is not the most effective way to prevent the spread of pathogens during patient care. Hand hygiene remains the most effective measure in preventing the spread of pathogens.
Correct Answer is D
Explanation
Choice A rationale
Aspiration is not a common complication of TPN. TPN is administered intravenously, bypassing the gastrointestinal tract, which reduces the risk of aspiration. Choice B rationale
Polyuria, or excessive urination, is not typically a direct complication of TPN. However, the fluid balance of patients on TPN should be monitored, as both overhydration and dehydration can lead to urinary changes.
Choice C rationale
Stomatitis, or inflammation of the mouth and lips, is not a common complication of TPN. Since TPN bypasses the gastrointestinal tract, it does not typically cause oral complications.
Choice D rationale
Abdominal distention can occur as a complication of TPN. This is because TPN can cause an imbalance in the gut flora, leading to gas production and bloating. Additionally, if a patient on TPN has an underlying condition that affects gut motility, they may experience abdominal distention.
