A nurse prepares to replace the nearly empty container of total parenteral nutrition (TPN) for a client when she finds that there has been a delay in receiving the new container of solution from the pharmacy.

Which of the following solutions should the nurse infuse until the next container of TPN solution becomes available?

Dextrose 10% in water.

3% sodium chloride.

0.9% sodium chloride.

Lactated Ringer's. .

Answer and Explanation

The Correct Answer is A

Choice A rationale:
Dextrose 10% in water can be used as a temporary replacement for TPN to prevent hypoglycemia until the TPN solution is available.
Choice B rationale:
3% sodium chloride is a hypertonic solution and is not typically used as a replacement for TPN.
Choice C rationale:
0.9% sodium chloride, or normal saline, does not provide the necessary nutrients that are included in TPN.
Choice D rationale:
Lactated Ringer’s is used for fluid resuscitation and does not provide the necessary nutrients that are included in TPN.

Correct Answer is A

Explanation

Choice A rationale:
Varicose veins with ulcerations and lower extremity edema indicate poor blood flow, hence impaired tissue perfusion is the priority.
Choice B rationale:
While activity tolerance might be affected, it’s not the immediate concern.
Choice C rationale:
Impaired skin integrity is a concern due to ulcerations, but it’s secondary to impaired perfusion.
Choice D rationale:
Body image might be affected, but it’s not a physiological priority.

A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg. B. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg. C. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg. D. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg.

Correct Answer is A

Explanation

Choice A rationale:
These values indicate metabolic acidosis, which is common in clients with chronic kidney disease. The kidneys are unable to excrete hydrogen ions and reabsorb bicarbonate, leading to a low pH and low bicarbonate levels.
Choice B rationale:
These values indicate alkalosis, not typically associated with chronic kidney disease. The pH is high, indicating a basic or alkaline state, and the bicarbonate level is normal.
Choice C rationale:
These values indicate metabolic alkalosis, which is not typically seen in clients with chronic kidney disease. The pH and bicarbonate levels are both high.
Choice D rationale:
These values indicate respiratory acidosis, not typically associated with chronic kidney disease. The high PaCO2 level indicates that the lungs are not effectively eliminating CO2, leading to acidosis.
