A nurse is reviewing the laboratory report of a client and identifies a serum potassium level of 6.8 mEq/L. Which of the following medications should the nurse plan to administer?
Lactulose
Sevelamer
Sodium polystyrene
Darbepoetin alfa
The Correct Answer is C
A. Lactulose: Lactulose is used to reduce blood ammonia levels in hepatic encephalopathy, not to reduce potassium levels. It is not appropriate for treating hyperkalemia.
B. Sevelamer: Sevelamer is a phosphate binder used in clients with chronic kidney disease to lower serum phosphorus levels, not potassium. It is not appropriate for treating hyperkalemia.
C. Sodium polystyrene: Sodium polystyrene (Kayexalate) is a cation-exchange resin used to treat hyperkalemia. It works by exchanging sodium ions for potassium ions in the intestine, promoting the excretion of potassium. This is the correct medication to administer for a serum potassium level of 6.8 mEq/L.
D. Darbepoetin alfa: Darbepoetin alfa is a synthetic erythropoietin used to treat anemia associated with chronic kidney disease. It is not used to treat hyperkalemia.

Correct Answer is C
Explanation
A. The nurse coats the indwelling urinary catheter with lubricant. This is correct procedure and requires no intervention. Lubricating the catheter reduces friction and discomfort during insertion.
B. The nurse applies the sterile drape prior to inserting the urinary catheter. This is correct procedure and requires no intervention. The sterile drape maintains a sterile field.
C. The nurse separates the client's labia with her dominant hand. The nurse should separate the client's labia with her non-dominant hand, which then remains in place as a "dirty" hand. The dominant hand, which remains sterile, is used to insert the catheter.
D. The nurse provides perineal care prior to inserting the urinary catheter. This is correct procedure and requires no intervention. Perineal care reduces the risk of introducing bacteria into the urinary tract.
Correct Answer is C
Explanation
A. Body Image: Body image stressors relate to how a person perceives their physical self. This is not relevant to the scenario of work and family stress.
B. Self-esteem: Self-esteem stressors relate to a person’s sense of self-worth. While stress from work and family can affect self-esteem, the primary issue here is more related to role performance.
C. Role performance: Role performance stressors relate to how well an individual perceives they are fulfilling their roles in life, such as work, parenting, or caregiving. The client’s stress about balancing work and family responsibilities indicates a role performance issue. This is the correct answer.
D. Identity: Identity stressors involve a person’s sense of who they are. While stress from work and family can affect identity, the primary issue here is more specifically related to role performance.
