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 B
Explanation
A. "You will wear an external collection bag to drain your urine." An external collection bag is required for an ileal conduit, not a neobladder, where urine is stored internally.
B. "You will have an internal pouch to store your urine." A neobladder is created using a portion of the intestine to form a new bladder, which stores urine internally. The client may be able to void through the urethra.
C. "You will have a stoma that is located in your abdomen." A stoma is associated with an ileal conduit or a urostomy, not with a neobladder. A neobladder does not require an external stoma.
D. "You will not be able to control your urination." Initially, the client may have difficulty controlling urination until they learn how to use the neobladder. Over time, they may regain some control.
Correct Answer is A
Explanation
A. Secure new tracheostomy ties before removing old ones. Securing the new ties before removing the old ones prevents accidental decannulation of the tracheostomy tube.
B. Use aseptic technique. Aseptic technique should be used to reduce the risk of infection during tracheostomy care.
C. Apply suction when inserting the catheter. Suction should only be applied when withdrawing the catheter, not during insertion, to prevent trauma to the trachea and bronchial tissues.
D. Clean the inner cannula with mild soap and water. The inner cannula should be cleaned with sterile saline or a prescribed solution, not with soap, to avoid irritation and infection.
