A nurse is preparing to administer warfarin to a client who has chronic atrial fibrillation. Which of the following laboratory values should the nurse monitor prior to administering the medication?
LDL
INR
BUN
Hct
The Correct Answer is B
Choice A Reason:
LDL (Low-Density Lipoprotein) is incorrect. This is a type of cholesterol and is not specifically monitored in relation to warfarin therapy.
Choice B Reason:
INR (International Normalized Ratio) is correct. Warfarin is an anticoagulant medication, and its dosage needs to be adjusted based on the INR levels. INR monitoring helps assess the clotting tendency of the blood and ensures that the dosage of warfarin is within the therapeutic range to prevent blood clots without causing excessive bleeding.
Choice C Reason:
BUN (Blood Urea Nitrogen) is incorrect. This value is primarily used to assess kidney function and is not directly related to monitoring warfarin therapy.
Choice D Reason:
Hct (Hematocrit) is incorrect. This measures the percentage of red blood cells in the blood and is not directly related to monitoring warfarin therapy for atrial fibrillation.

Correct Answer is C
Explanation
Choice A Reason:
Chill the dialysate prior to infusion. Generally, the dialysate used in peritoneal dialysis is warmed to body temperature before infusion to enhance comfort and prevent abdominal discomfort. Chilling the dialysate can cause discomfort and is not a standard practice in peritoneal dialysis.
Choice B Reason:
Monitor the client for diarrhea. While gastrointestinal symptoms might occur in some individuals undergoing peritoneal dialysis due to changes in fluid balance, diarrhea is not a typical or expected outcome. However, monitoring for any unusual gastrointestinal symptoms or changes in bowel habits is part of holistic client care.
Choice C Reason:
Weigh the client before and after the treatment. Weighing the client before and after peritoneal dialysis is a critical step to assess the effectiveness of the treatment. The difference in weight helps determine how much fluid was removed during the dialysis process, providing valuable information about the treatment's efficacy and the client's fluid status.
Choice D Reason:
Use clean gloves when handling dialysate bags. Maintaining aseptic technique during peritoneal dialysis is crucial to prevent infections. The use of clean gloves (not sterile gloves, unless otherwise specified) when handling dialysate bags helps minimize the risk of contamination, ensuring the safety of the procedure.

Correct Answer is D
Explanation
Choice A Reason:
Preparing the sterile dressing supplies 30 min before the dressing change is correct. While it's crucial to have all supplies ready before starting the procedure, preparing them 30 minutes in advance might not align with the principles of maintaining sterility. It's generally best to prepare sterile supplies just before the procedure to minimize the risk of contamination.
Choice B Reason:
Don sterile gloves before removing the dressing is incorrect. Sterile gloves should indeed be worn during the dressing change, but they should be put on after removing the old dressing. This ensures that the clean gloves don't touch potentially contaminated surfaces during the removal of the old dressing.
Choice C Reason:
Disinfect the wound bed with alcohol before applying tape is incorrect. Using alcohol to disinfect the wound bed is not recommended as it can cause tissue irritation and delay wound healing. Sterile saline or another wound cleansing solution prescribed for wound care would be more appropriate to clean the wound bed. Additionally, applying tape directly to the wound is generally avoided to prevent further damage to the fragile tissues of a pressure ulcer.
Choice D Reason:
Offering the client pain medication before the procedure is correct. Providing pain medication before the procedure ensures the client's comfort and helps manage any discomfort or pain associated with the dressing change, particularly when dealing with a stage III pressure ulcer, which can be quite sensitive.
