A nurse is caring for a client who is receiving total parenteral nutrition (TPN). The nurse notices that the solution bag is almost empty and there is not another bag of TPN to administer. Which of the following IV solutions should the nurse administer until the next bag of TPN solution is available?
Explanation & Rationale
Choice A reason: While DSLR contains dextrose, it is not concentrated enough to maintain the glucose and osmolarity levels required for patients dependent on TPN. It also contains electrolytes that may not be appropriate for all TPN patients. Choice B reason: D10W is the preferred solution when TPN is temporarily unavailable. It helps maintain blood glucose levels and prevents hypoglycemia due to the abrupt discontinuation of TPN, which contains high concentrations of dextrose. Choice C reason: 0.45% NaCl is a hypotonic solution and does not provide the necessary glucose to prevent hypoglycemia. It is not suitable as a temporary replacement for TPN. Choice D reason: Lactated Ringer’s is an isotonic solution used for fluid resuscitation and electrolyte replacement. It lacks sufficient dextrose and is not appropriate for maintaining metabolic needs in TPN-dependent patients.
