Nursing Elites

1. A client is receiving dietary instructions from a nurse regarding warfarin sodium (Coumadin) therapy. The nurse advises the client to avoid which food item?

• A. Grapes
• B. Spinach
• C. Watermelon
• D. Cottage cheese

Correct answer: B

Rationale: The correct answer is B: Spinach. Spinach is high in vitamin K, which antagonizes the effects of warfarin sodium, an anticoagulant medication. Clients taking warfarin should avoid consuming foods rich in vitamin K, like spinach, to maintain the medication's effectiveness. Grapes (choice A), watermelon (choice C), and cottage cheese (choice D) do not interfere with the effects of warfarin, so they are safe for the client to consume while on warfarin therapy.

2. A client has a prescription to take guaifenesin (Humibid) every 4 hours, as needed. The nurse determines that the client understands the most effective use of this medication if the client states that he or she will:

• A. Watch for irritability as a side effect.
• B. Take the tablet with a full glass of water.
• C. Take an extra dose if the cough is accompanied by fever.
• D. Crush the sustained-release tablet if immediate relief is needed.

Correct answer: B

Rationale: Guaifenesin is an expectorant used to help loosen mucus and make coughs more productive. Taking it with a full glass of water helps decrease the viscosity of secretions, making it easier to expel mucus from the respiratory tract. It is important not to crush sustained-release tablets, as this can alter the intended release of the medication and lead to potential adverse effects.

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. The healthcare provider is applying a topical corticosteroid to a client with eczema. The healthcare provider should monitor for the potential of increased systemic absorption of the medication if the medication were being applied to which of the following body areas?

• A. Back
• B. Axilla
• C. Soles of the feet
• D. Palms of the hands

Correct answer: B

Rationale: The axilla has thinner skin, making it more permeable to topical medications. Areas with thinner skin, like the axilla, allow for higher systemic absorption of topical corticosteroids.

5. A client is receiving vancomycin (Vancocin). Which of the following is the most important action for the nurse to take?

• A. Monitor the client for signs of nephrotoxicity.
• B. Monitor the client for signs of ototoxicity.
• C. Ensure adequate hydration.
• D. Administer the medication with food.

Correct answer: A

Rationale: The most important action for the nurse to take when a client is receiving vancomycin is to monitor for signs of nephrotoxicity. Vancomycin can cause kidney damage, so monitoring kidney function and signs of nephrotoxicity are crucial to prevent harm. While monitoring for ototoxicity and ensuring adequate hydration are important nursing actions, they are not as critical as preventing nephrotoxicity when administering vancomycin.
