The nurse is caring for the client with cardiac and renal disease. The client now has a serum potassium level of 6.0 mEq/L. Which medications, if prescribed, should the nurse administer? Select all that apply.

A. Collect a urine sample from the client: While collecting a urine sample may be necessary for further assessment, it is not the priority in this situation. The client's symptoms of lower back pain, feeling chilled, and itching suggest a potential transfusion reaction, which requires immediate attention to ensure the client's safety. Therefore, collecting a urine sample is not the most appropriate initial action.

B. Return the platelet bag and tubing to the blood bank: Returning the platelet bag and tubing to the blood bank may be necessary after stopping the infusion, but it is not the first action the nurse should take. Stopping the infusion and assessing the client's condition are the immediate priorities to address the potential transfusion reaction.

C. Notify the provider: While it is important to notify the provider about the client's symptoms and the suspected transfusion reaction, this action should follow after stopping the infusion and assessing the client's condition. Immediate intervention to ensure the client's safety takes precedence over contacting the provider.

D. Stop the infusion: This is the correct action. The client's symptoms of lower back pain, feeling chilled, and itching are indicative of a potential transfusion reaction, such as febrile non-hemolytic transfusion reaction or allergic reaction. The immediate priority is to stop the infusion to prevent further administration of platelets and assess the client's condition. This action takes precedence over other interventions as addressing the client's safety and well-being is paramount in the event of a transfusion reaction.

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.
