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. A client with trigeminal neuralgia tells the nurse that acetaminophen (Tylenol) is taken on a frequent daily basis for relief of generalized discomfort. The nurse reviews the client's laboratory results and determines that which of the following indicates toxicity associated with the medication?

• A. Sodium of 140 mEq/L
• B. Prothrombin time of 12 seconds
• C. Platelet count of 400,000 cells/mm³
• D. A direct bilirubin level of 2 mg/dL

Correct answer: D

Rationale: A direct bilirubin level of 2 mg/dL indicates liver damage, which can be caused by an overdose of acetaminophen. Acetaminophen toxicity can lead to liver injury, manifesting as elevated bilirubin levels and other liver function test abnormalities.

3. A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?

• A. Withdraws the NPH insulin first
• B. Withdraws the regular insulin first
• C. Injects air into the NPH insulin vial first
• D. Injects an amount of air equal to the desired dose of insulin into the vial

Correct answer: A

Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching. Choice B is correct as withdrawing regular insulin first is the appropriate step. Choice C is incorrect as air should be injected into the vial containing the regular insulin to maintain pressure. Choice D is incorrect as injecting air equal to the desired dose of insulin into the vial is a correct step in preparing the insulin for withdrawal.

4. A client has been taking isoniazid (INH) for 2 months. The client complains to a nurse about numbness, paresthesias, and tingling in the extremities. The nurse interprets that the client is experiencing:

• A. Hypercalcemia
• B. Peripheral neuritis
• C. Small blood vessel spasm
• D. Impaired peripheral circulation

Correct answer: B

Rationale: The client's symptoms of numbness, paresthesias, and tingling in the extremities indicate peripheral neuritis, a common side effect of isoniazid (INH). This condition can be managed by supplementing with pyridoxine (vitamin B6) to minimize the symptoms.

5. When a client taking warfarin sodium (Coumadin) is prescribed ciprofloxacin (Cipro), the nurse should closely monitor the client for which potential effect of this drug interaction?

• A. Increased risk of bleeding
• B. Decreased warfarin effectiveness
• C. Increased risk of thrombosis
• D. Decreased ciprofloxacin effectiveness

Correct answer: A

Rationale: When ciprofloxacin (Cipro) is given with warfarin sodium (Coumadin), it can potentiate the effects of warfarin, leading to an increased risk of bleeding. Therefore, the nurse should closely monitor the client's INR levels and watch for signs of bleeding such as bruising, petechiae, or black tarry stools.
