A nurse is caring for an older adult client. The nurse informs the client that straining while defecating can cause which of the following?

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) Lactated Ringer's:
Lactated Ringer's solution is an isotonic crystalloid solution that contains electrolytes similar to those found in plasma. It is commonly used for fluid resuscitation and maintenance therapy but is not typically used for treating hypernatremia, as it contains sodium chloride and could exacerbate the client's condition.

B) Dextrose 10% in water:
Dextrose 10% in water is a hypertonic solution primarily used to provide calories and treat hypoglycemia. It does not address the underlying electrolyte imbalance in hypernatremia.

C) 0.45% sodium chloride:
0.45% sodium chloride, also known as half-normal saline, is a hypotonic solution used to treat hypernatremia by diluting the excess sodium in the bloodstream. It provides free water to rehydrate cells without adding excessive sodium. This solution is appropriate for clients with hypernatremia who require IV fluid therapy.

D) Dextrose 5% in 0.9% sodium chloride:
Dextrose 5% in 0.9% sodium chloride, also known as D5NS, is a hypertonic solution containing both dextrose and sodium chloride. While it provides water and calories, the sodium content may exacerbate hypernatremia rather than correct it. Therefore, it is not the most appropriate choice for a client with hypernatremia.
