Nursing Elites

1. A nurse is caring for a client who is receiving furosemide. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?

• A. Serum sodium.
• B. Serum glucose.
• C. Serum potassium.
• D. Serum calcium.

Correct answer: C

Rationale: The correct answer is C: Serum potassium. Furosemide is a potassium-wasting diuretic, meaning it can lead to potassium loss in the body. Monitoring serum potassium levels is crucial to evaluate the effectiveness of furosemide and prevent hypokalemia. Options A, B, and D are incorrect because furosemide does not directly affect sodium, glucose, or calcium levels in the same way it impacts potassium levels.

2. A nurse is providing discharge teaching to a client who has a new prescription for warfarin. Which of the following instructions should the nurse include?

• A. You should avoid consuming foods high in vitamin K.
• B. Take this medication at the same time each day.
• C. Monitor for signs of bruising and bleeding.
• D. Have your INR checked every 4 weeks.

Correct answer: A

Rationale: The correct instruction the nurse should include is to advise the client to avoid consuming foods high in vitamin K. Foods rich in vitamin K, such as leafy greens, can interfere with the effectiveness of warfarin, an anticoagulant medication. Therefore, it is important for clients on warfarin therapy to maintain consistent vitamin K intake to keep their INR levels stable. The other options are also important but not the priority in the context of warfarin therapy. Ingesting foods high in vitamin K can affect the medication's efficacy, making it crucial to highlight this dietary consideration during client education.

3. Which of the following lab values indicates a patient on warfarin is at a therapeutic level?

• A. INR of 1.1
• B. PT of 12 seconds
• C. INR of 2.5
• D. Platelet count of 150,000

Correct answer: C

Rationale: An INR of 2.5 indicates a therapeutic level for a patient on warfarin. The INR (International Normalized Ratio) is the most accurate way to monitor and adjust warfarin doses. An INR of 1.1 (Choice A) is below the therapeutic range, indicating a need for an increased dose. PT (Prothrombin Time) of 12 seconds (Choice B) is not specific for warfarin therapy monitoring. Platelet count (Choice D) is not directly related to monitoring warfarin therapy.

4. A nurse is reviewing the prescription for doxazosin with a client. Which of the following should be included in the teaching?

• A. Decrease caloric intake to prevent weight gain.
• B. Increase dietary fiber to alleviate constipation.
• C. Rise slowly when sitting up from bed.
• D. Take this medication in the morning.

Correct answer: C

Rationale: The correct answer is C. Doxazosin can cause orthostatic hypotension, leading to dizziness and falls if the client rises quickly from a seated position. Instructing the client to rise slowly when sitting up from bed helps prevent these adverse effects. Choices A, B, and D are incorrect because doxazosin does not directly relate to caloric intake, dietary fiber, or a specific time of day for administration.

5. A client has a stage 3 pressure injury. Which of the following interventions should the nurse include in the plan?

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

Correct answer: D

Rationale: The correct intervention for a client with a stage 3 pressure injury is to apply a moisture barrier ointment. This helps protect the skin, maintain moisture balance, and promote healing. Choice A is incorrect because povidone-iodine solution can be too harsh for wound care. Choice B is incorrect as hydrogen peroxide can be cytotoxic to healing tissue. Choice C is important for preventing pressure injuries but is not a direct intervention for a stage 3 wound.
