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. When monitoring a client for acute toxicity associated with bethanechol chloride (Urecholine), what sign should the nurse check for to indicate toxicity?

• A. Dry skin
• B. Dry mouth
• C. Bradycardia
• D. Signs of dehydration

Correct answer: C

Rationale: The correct answer is C: Bradycardia. Toxicity from bethanechol chloride (Urecholine) can lead to excessive muscarinic stimulation, resulting in manifestations like salivation, sweating, involuntary urination and defecation, bradycardia, and severe hypotension. When facing toxicity, treatment involves supportive measures and administering atropine sulfate subcutaneously or intravenously.

3. A client with type 2 diabetes mellitus is prescribed metformin (Glucophage). Which instruction should the nurse include in the teaching plan?

• A. Take the medication with meals.
• B. Monitor for signs of hypoglycemia.
• C. Avoid alcohol while taking this medication.
• D. Take the medication at bedtime.

Correct answer: C

Rationale: Clients taking metformin (Glucophage) should avoid alcohol as it can increase the risk of lactic acidosis. Metformin should be taken with meals to reduce gastrointestinal upset. While hypoglycemia is less common with metformin compared to other diabetes medications, clients should still be aware of its symptoms.

4. A clinic nurse prepares to administer an MMR (measles, mumps, rubella) vaccine to a child. How is this vaccine best administered?

• A. Intramuscularly in the deltoid muscle
• B. Subcutaneously in the gluteal muscle
• C. Subcutaneously in the outer aspect of the upper arm
• D. Intramuscularly in the anterolateral aspect of the thigh

Correct answer: C

Rationale: The MMR vaccine is best administered subcutaneously in the outer aspect of the upper arm. This route allows for proper absorption and efficacy of the vaccine while minimizing the risk of injury or discomfort to the child.

5. 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.
