Nursing Elites

1. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:

• A. Releases bicarbonate in exchange for primarily sodium ions
• B. Releases sodium ions in exchange for primarily potassium ions
• C. Releases potassium ions in exchange for primarily sodium ions
• D. Releases sodium ions in exchange for primarily bicarbonate ions

Correct answer: B

Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.

2. Insulin glargine (Lantus) is prescribed for a client with diabetes mellitus. The nurse tells the client that it is best to take the insulin:

• A. 1 hour after each meal
• B. Once daily, at the same time each day
• C. 15 minutes before breakfast, lunch, and dinner
• D. Before each meal, based on the blood glucose level

Correct answer: B

Rationale: Insulin glargine (Lantus) is a long-acting insulin with a duration of action of approximately 24 hours, making it suitable for once-daily dosing at the same time each day. This regimen helps maintain consistent blood glucose levels and simplifies the client's treatment routine. Taking insulin glargine once daily provides basal insulin coverage throughout the day, reducing the risk of hypoglycemia compared to short-acting insulins that are taken before each meal.

3. The client with a gastric ulcer has a prescription for sucralfate (Carafate), 1 g by mouth four times daily. The nurse schedules the medication for which times?

• A. With meals and at bedtime
• B. Every 6 hours around the clock
• C. One hour after meals and at bedtime
• D. One hour before meals and at bedtime

Correct answer: D

Rationale: Sucralfate is a gastric protectant that forms a protective coating over the ulcer. Administering sucralfate 1 hour before meals and at bedtime is important to create a barrier that protects the ulcer from gastric acid and mechanical irritation. This timing allows sucralfate to effectively coat the ulcer site and provide the desired therapeutic effect, enhancing its efficacy in promoting ulcer healing and symptom relief.

4. A client with type 2 diabetes mellitus is prescribed glipizide (Glucotrol). Which instruction should the nurse include in the teaching plan?

• A. Take the medication before a meal.
• B. Monitor for signs of hypoglycemia.
• C. Avoid alcohol consumption while taking this medication.
• D. Take the medication before bedtime.

Correct answer: B

Rationale: The correct instruction the nurse should include in the teaching plan for a client prescribed glipizide (Glucotrol) is to monitor for signs of hypoglycemia. Glipizide stimulates insulin release from the pancreas, which can lead to hypoglycemia. It is usually taken before a meal, not necessarily on an empty stomach. Alcohol consumption should be avoided to prevent interactions with the medication. Taking the medication before bedtime is not the typical recommendation.

5. Mafenide acetate (Sulfamylon) is prescribed for a client with a burn injury. When applying the medication, the client complains of local discomfort and burning. Which of the following is the most appropriate nursing action?

• A. Notifying the registered nurse
• B. Discontinuing the medication
• C. Informing the client that this is normal
• D. Applying a thinner film than prescribed to the burn site

Correct answer: C

Rationale: The correct action is to inform the client that local discomfort and burning are normal reactions to Mafenide acetate. This medication is used to treat burns by reducing bacteria in avascular tissues. Discontinuing the medication or applying a thinner film than prescribed is not necessary or recommended in this situation.
