A nurse is caring for a client who has a prescription for total parental nutrition (TPN).
Which of the following routes of administration should the nurse use?
Subcutaneous
Intraosseous
Midline catheter
Central venous access device
The Correct Answer is D
Choice A rationale: TPN cannot be administered subcutaneously due to its composition.
Choice B rationale: Intraosseous access is for emergency situations when IV access isn't attainable.
Choice C rationale: A midline catheter might not be suitable for the hypertonic nature of TPN and can lead to complications.
Choice D rationale: Total parenteral nutrition (TPN) is a hypertonic solution that requires infusion into a large vein. The central venous access device allows for high-flow rates and avoids irritation or damage to smaller peripheral veins.

Correct Answer is D
Explanation
Choice A rationale: Calcium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice B rationale: Magnesium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice C rationale: Sodium levels might not directly reflect the effectiveness of sodium polystyrene sulfonate.
Choice D rationale: Sodium polystyrene sulfonate is used to lower potassium levels in conditions like hyperkalemia. A decrease in potassium levels (within normal range)
indicates effectiveness.
Correct Answer is A
Explanation
Choice A rationale: A lithium level of 2.6 mEq/L is significantly elevated and poses a risk of lithium toxicity. Hemodialysis is the most effective intervention to rapidly lower the lithium level in severe cases of toxicity.
Choice B rationale: Left lateral positioning is not the priority in this situation; immediate intervention to lower the lithium level is necessary.
Choice C rationale: Fluid restrictions alone might not rapidly lower the elevated lithium level in severe toxicity.
Choice D rationale: Given the elevated level, increasing the dosage would exacerbate toxicity and is inappropriate.
