1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?

• A. Blood glucose level
• B. Prothrombin time (PT) and INR
• C. Serum potassium level
• D. Serum creatinine level

Correct answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

2. A client with rheumatoid arthritis is prescribed methotrexate. What information should the LPN include when teaching the client about this medication?

• A. Avoid exposure to sunlight.
• B. Take the medication with food.
• C. Increase fluid intake while on this medication.
• D. Report any signs of infection to the healthcare provider immediately.

Correct answer: D

Rationale: The correct answer is D: 'Report any signs of infection to the healthcare provider immediately.' Methotrexate is an immunosuppressant medication commonly used to treat rheumatoid arthritis. It can lower the immune system's ability to fight infections, making it crucial for clients to promptly report any signs of infection to prevent serious complications. Choices A, B, and C are incorrect because avoiding sunlight, taking the medication with food, and increasing fluid intake are not specific to methotrexate therapy and are not primary concerns associated with this medication.

3. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)

• A. 400 mL/hr
• B. 200 mL/hr
• C. 300 mL/hr
• D. 250 mL/hr

Correct answer: A

Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.

4. A client is receiving a blood transfusion. The client reports flank pain, and the nurse notes reddish-brown urine in the client's urinary catheter bag. The nurse recognizes these manifestations as which of the following types of transfusion reactions?

• A. Hemolytic
• B. Allergic
• C. Febrile
• D. Transfusion-related acute lung injury (TRALI)

Correct answer: A

Rationale: The correct answer is A: Hemolytic. Hemolytic reactions can lead to flank pain and hemoglobinuria, as the body breaks down the transfused red blood cells. In hemolytic reactions, the immune system attacks and destroys the transfused red blood cells, causing the release of hemoglobin into the bloodstream and urine. This results in reddish-brown urine, indicating hemoglobinuria. Allergic reactions typically present with symptoms like itching, hives, or rash. Febrile reactions are characterized by fever, chills, and rigors. TRALI is a rare but serious transfusion reaction that manifests as acute respiratory distress following a transfusion, not flank pain and hemoglobinuria.

5. What is the rate of delivery in mL/hr if a total volume of 750 mL is infused over a period of 7 hours?

• A. 107 mL/hr.
• B. 107 mL/hr.
• C. 107 mL/hr.
• D. 107 mL/hr.

Correct answer: A

Rationale: The correct rate of delivery is 107 mL/hr. To find the rate of delivery, divide the total volume by the total time: 750 mL / 7 hours = 107 mL/hr. Choice B, C, and D are incorrect as they do not match the correct calculation based on the total volume and time provided.
