Nursing Elites

1. When speaking to young parents, the nurse states that lead poisoning is one of the most common preventable health problems affecting children. What condition occurs when the level of lead ingested exceeds the amount that can be absorbed by the bone?

• A. Malnutrition
• B. Anemia
• C. Bone pain
• D. Diarrhea

Correct answer: B

Rationale: The correct answer is B: Anemia. When the amount of lead ingested exceeds the amount that can be absorbed by the bone, it leads to anemia. Malnutrition (Choice A) is a state of inadequate nutrition, not directly related to lead poisoning. Bone pain (Choice C) is a symptom of lead poisoning due to its effects on bones but not directly related to lead ingestion exceeding absorption. Diarrhea (Choice D) is not a direct consequence of lead ingestion exceeding absorption by bones.

2. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?

• A. 16 ml/hour.
• B. 18 ml/hour.
• C. 20 ml/hour.
• D. 22 ml/hour.

Correct answer: C

Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

3. The nurse assesses an adult male client 24 hours following abdominal surgery and finds that his blood pressure is 98/40 mm Hg, he is tachycardic, restless, and irritable. Which action should the nurse take first?

• A. Notify the healthcare provider of the findings.
• B. Ensure that the IV is infusing at the prescribed rate.
• C. Listen to lung sounds.
• D. Check under his back for evidence of bleeding.

Correct answer: D

Rationale: In this scenario, the nurse should first check under the client for evidence of bleeding. A blood pressure of 98/40 mm Hg, along with tachycardia, restlessness, and irritability, could indicate internal hemorrhage following abdominal surgery. Checking for bleeding under the back is crucial to rule out this life-threatening complication. Notifying the healthcare provider, ensuring IV infusion, or listening to lung sounds can be important but are secondary to ruling out immediate life-threatening conditions like internal bleeding.

4. A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin?

• A. Complete blood count (CBC)
• B. Activated partial thromboplastin time (aPTT)
• C. Prothrombin time (PT)
• D. International normalized ratio (INR)

Correct answer: B

Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.

5. The client with chronic venous insufficiency is being taught about self-care measures. Which instruction should be included?

• A. Avoid wearing compression stockings
• B. Elevate legs above heart level when resting
• C. Apply heat packs to improve circulation
• D. Limit walking to prevent leg pain

Correct answer: B

Rationale: The correct instruction for a client with chronic venous insufficiency is to elevate their legs above heart level when resting. This position helps reduce venous pressure and edema, improving circulation. Avoiding compression stockings (choice A) is incorrect as they are beneficial in managing chronic venous insufficiency. Applying heat packs (choice C) is not recommended as heat can worsen edema. Limiting walking (choice D) is not advisable as regular, gentle exercise like walking can actually help improve circulation in patients with chronic venous insufficiency.
