1. Which lab value is critical for monitoring warfarin therapy?

• A. Monitor INR
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A client has a new prescription for enoxaparin. Which of the following instructions should the nurse include?

• A. Massage the injection site after administering the medication.
• B. Pinch the skin while administering the injection.
• C. Administer the medication at bedtime.
• D. Aspirate before injecting the medication.

Correct answer: B

Rationale: When administering enoxaparin, it is important to pinch the skin to ensure proper subcutaneous injection. Massaging the injection site after administering the medication is not recommended. Administering the medication at bedtime is not a specific requirement for enoxaparin. Aspirating before injecting the medication is not necessary for subcutaneous injections like enoxaparin.

3. A nurse is planning care for a client who has a stage 3 pressure injury. Which of the following interventions should the nurse include in the plan of care?

• A. Cleanse the wound with povidone-iodine solution daily.
• B. Irrigate the wound with hydrogen peroxide.
• C. Reposition the client every 4 hours.
• D. Use a moisture barrier ointment.

Correct answer: D

Rationale: The correct answer is to use a moisture barrier ointment. This intervention helps protect the skin and promote healing in clients with stage 3 pressure injuries. Cleansing the wound with povidone-iodine solution daily (Choice A) can be too harsh and may delay healing by damaging the surrounding skin. Irrigating the wound with hydrogen peroxide (Choice B) is not recommended as it can be cytotoxic to healing tissue. While repositioning the client every 4 hours (Choice C) is an essential intervention in preventing pressure injuries, it is not directly related to the care of an existing stage 3 pressure injury.

4. A client has a new prescription for ferrous sulfate. Which of the following instructions should the nurse include in the teaching?

• A. Take this medication on an empty stomach.
• B. Take this medication with milk if it causes stomach upset.
• C. Take this medication with orange juice to increase absorption.
• D. Take an antacid 1 hour after this medication.

Correct answer: C

Rationale: The correct instruction is to take ferrous sulfate with orange juice to increase absorption because the vitamin C content in orange juice enhances iron absorption. Choice A is incorrect because ferrous sulfate should be taken with food to reduce gastrointestinal side effects. Choice B is incorrect because milk can decrease iron absorption. Choice D is incorrect because antacids can reduce the absorption of ferrous sulfate.

5. A client is preparing advance directives. Which of the following statements by the client indicates an understanding of advance directives?

• A. I cannot change my instructions once I have signed them.
• B. My doctor will need to approve my advance directives.
• C. I need a witness to sign my advance directives.
• D. I have the right to refuse treatment.

Correct answer: D

Rationale: The correct answer is D: 'I have the right to refuse treatment.' This statement shows an understanding of advance directives because they allow individuals to specify their treatment preferences in advance, including the right to refuse treatment. Choices A, B, and C are incorrect. Choice A is inaccurate as individuals can update or change their advance directives at any time. Choice B is incorrect because while a doctor may discuss advance directives with the client, approval is not required for the directives to be valid. Choice C is also incorrect as a witness is typically required to verify the client's signature, not the other way around.
