A nurse assesses four patients. Which patient has greatest risk for hypomagnesemia?

A. Prime the blood tubing with dextrose 5% in water:
Priming the blood tubing with dextrose 5% in water is not appropriate for a blood transfusion. Blood tubing should be primed with normal saline, not dextrose solutions, to prevent hemolysis of the blood components.
B. Check vital signs before transfusion:
Before initiating a blood transfusion, it's essential to assess the client's vital signs, including temperature, pulse, respiratory rate, and blood pressure. Monitoring vital signs before, during, and after the transfusion helps identify any adverse reactions promptly.
C. Insert an IV with a 13-gauge needle:
Using a 13-gauge needle for IV insertion is not appropriate for a blood transfusion. Typically, a smaller gauge needle, such as 18 or 20 gauge, is used for venous access during a blood transfusion to minimize discomfort and reduce the risk of hemolysis.
D. Transfuse the blood product within 5 hr after removing it from refrigeration:
Blood products should be transfused within a specific timeframe after removal from refrigeration to minimize the risk of bacterial growth and subsequent infection. Typically, this timeframe is within 4 hours for packed red blood cells and within 24 hours for platelets. Adhering to the recommended timeframe ensures the safety and efficacy of the transfusion.
E. Check the expiration date of the blood product with a second nurse:
Verifying the expiration date of the blood product with a second nurse or healthcare provider is a crucial step to ensure patient safety and prevent the administration of expired blood products. This double-check process helps mitigate the risk of administering outdated or expired blood components.

A) Administer 200 mL of formula during the initial infusion:
The initial infusion rate for continuous enteral feeding is typically started at a slower rate, often lower than 200 mL, to assess the client's tolerance and prevent complications such as aspiration or dumping syndrome.

B) Give the initial feeding over 15 min:
Continuous enteral feeding is administered slowly over an extended period, usually 24 hours, to ensure gradual delivery of nutrients and minimize the risk of complications such as aspiration or gastrointestinal intolerance. Giving the initial feeding over 15 minutes is too rapid and can lead to adverse events.

C) Reconstitute the formula with tap water:
Reconstituting enteral formula with tap water is not recommended due to the potential risk of contamination with bacteria or other pathogens. It's essential to use sterile water or water that has been specifically purified for enteral feeding to minimize the risk of infection.

D) Discard unused formula after 8 hr:
Unused formula should be discarded after 4 hours, not 8 hours, to reduce the risk of bacterial contamination and ensure the integrity of the enteral nutrition. This practice aligns with guidelines for safe enteral feeding administration.
