A nurse is caring for a client with severe anemia. The provider placed an order for one unit of packed red blood cells (PRBCs) x 1 now. The nurse should anticipate the blood will be completely infused after how much time?

A) D5W: Dextrose 5% in water (D5W) is not used with blood transfusions because it can cause hemolysis of the red blood cells due to its hypotonic nature. It can also potentially cause clumping and clotting.

B) 0.3% NS: This is a hypotonic saline solution, which can lead to hemolysis of red blood cells when used as a diluent for blood products. It is not appropriate for use in blood transfusions.

C) Lactated Ringers: Although lactated Ringer's solution is often used for fluid resuscitation, it contains calcium, which can cause clotting in the blood product. Therefore, it is not suitable for use with blood transfusions.

D) 0.9% NS: Normal saline (0.9% sodium chloride) is isotonic and the only solution recommended for use with blood transfusions. It does not cause hemolysis of red blood cells, does not alter the composition of the blood product, and helps to maintain the patency of the IV line. It is the standard diluent used in blood transfusions to ensure the safe administration of blood products.

A) Dysphagia: While dysphagia (difficulty swallowing) can occur in individuals with long-term alcohol use, especially if there is coexisting neurological damage or esophageal disorders, it is not specifically associated with vomiting and diarrhea in the context of this scenario. The primary concern here involves electrolyte imbalances.

B) Hypoactive deep tendon reflexes (DTR): Hypoactive DTRs are typically associated with hypermagnesemia rather than hypomagnesemia. In this case, the client's condition is more likely to lead to electrolyte deficiencies, including hypomagnesemia, due to vomiting, diarrhea, and poor nutritional intake.

C) Hypomagnesemia: Chronic alcohol use often results in nutritional deficiencies, and vomiting and diarrhea can further exacerbate this by depleting electrolytes. Hypomagnesemia is a common finding in long-term alcoholics due to poor dietary intake, gastrointestinal losses, and renal losses. This can lead to symptoms such as muscle weakness, tremors, and altered mental status. Hypomagnesemia is particularly concerning because it can affect cardiovascular stability and neuromuscular function.

D) Positive Chvostek sign: A positive Chvostek sign is indicative of hypocalcemia, which can occur secondary to hypomagnesemia. However, it is not as directly associated with chronic alcoholism as hypomagnesemia itself. The positive Chvostek sign involves a facial muscle spasm in response to tapping the facial nerve and indicates neuromuscular irritability due to low calcium levels. While related, the primary electrolyte imbalance expected here is hypomagnesemia.
