Nursing Elites

1. A patient with deep vein thrombosis (DVT) is prescribed warfarin. Which dietary instruction should the nurse provide?

• A. Avoid foods high in vitamin K.
• B. Increase intake of dairy products.
• C. Limit intake of citrus fruits.
• D. Avoid high-sodium foods.

Correct answer: A

Rationale: Patients on warfarin should avoid foods high in vitamin K because vitamin K can interfere with the anticoagulant effect of the medication. Warfarin works by inhibiting vitamin K-dependent clotting factors, so consuming large amounts of vitamin K-rich foods may decrease the effectiveness of the medication. Choices B, C, and D are incorrect. Increasing intake of dairy products, limiting citrus fruits, or avoiding high-sodium foods are not directly related to the mechanism of action of warfarin or its dietary considerations.

2. The client with chronic kidney disease (CKD) is receiving hemodialysis. Which finding should be reported to the healthcare provider immediately?

• A. Blood pressure of 150/90 mm Hg.
• B. Weight gain of 2 pounds since the last dialysis session.
• C. Blood glucose level of 120 mg/dl.
• D. Potassium level of 6.5 mEq/L.

Correct answer: D

Rationale: A potassium level of 6.5 mEq/L is dangerously high, a condition known as hyperkalemia, which can lead to severe cardiac complications like arrhythmias and cardiac arrest. Immediate medical intervention is necessary to lower potassium levels to prevent life-threatening outcomes in clients undergoing hemodialysis.

3. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?

• A. Serum glucose of 350 mg/dL.
• B. Serum potassium of 2.8 mEq/L.
• C. Serum sodium of 136 mEq/L.
• D. Serum bicarbonate of 20 mEq/L.

Correct answer: B

Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.

4. What skin care instructions should the nurse give to a patient receiving external beam radiation therapy for cancer treatment?

• A. Use a heating pad to relieve any pain in the treated area.
• B. Apply alcohol-based lotions to the treated area daily.
• C. Avoid exposing the treated area to sunlight.
• D. Wash the treated area with hot water and strong soap.

Correct answer: C

Rationale: Patients undergoing external beam radiation therapy should be advised to avoid exposing the treated area to sunlight to prevent further skin damage. Heat sources like heating pads should be avoided to prevent burns and irritation to the skin. Alcohol-based lotions can be irritating to the skin and are not recommended. Washing the treated area with lukewarm water and mild soap is preferable to maintain skin integrity and prevent irritation. Therefore, the correct instruction for the patient is to avoid exposing the treated area to sunlight.

5. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which instruction should the nurse provide?

• A. Avoid green leafy vegetables.
• B. Take aspirin for headaches.
• C. Use a soft-bristled toothbrush.
• D. Limit fluid intake to 1 liter per day.

Correct answer: C

Rationale: The correct instruction for a client on warfarin therapy, especially with a history of DVT, is to use a soft-bristled toothbrush. This is crucial to prevent gum bleeding, which is a risk due to the anticoagulant effects of warfarin. Green leafy vegetables are rich in vitamin K, which can interfere with warfarin's effectiveness, so they should be consumed consistently to maintain a balance. Aspirin is not recommended for headaches in clients on warfarin due to the increased risk of bleeding. Limiting fluid intake is not a standard instruction for clients on warfarin therapy.
