Nursing Elites

1. The healthcare provider prescribes an IV infusion of isoproterenol in D5W at 300 mcg/hour. How many ml/hour should the nurse set the pump to?

• A. 100 ml/hour
• B. 75 ml/hour
• C. 60 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct infusion rate, convert 300 mcg/hour to mg/hour (300 mcg = 0.3 mg). Since the IV solution is 1 mg in 250 ml, the rate is calculated as 0.3 mg/hour = 75 ml/hour. Therefore, the nurse should set the pump to 75 ml/hour. Choice A (100 ml/hour) is incorrect as it does not reflect the accurate calculation. Choice C (60 ml/hour) is incorrect as it is lower than the correct rate. Choice D (125 ml/hour) is incorrect as it is higher than the correct rate.

2. A client with peripheral artery disease reports leg cramps while walking. What intervention should the nurse recommend?

• A. Encourage the client to rest immediately when cramping occurs.
• B. Recommend that the client increase their intake of potassium-rich foods.
• C. Advise the client to take a short break, then continue walking.
• D. Recommend that the client avoid walking altogether to prevent cramps.

Correct answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

3. A client with peripheral artery disease reports pain while walking. What intervention should the nurse recommend?

• A. Encourage the client to increase physical activity.
• B. Instruct the client to take rest breaks during walking.
• C. Apply warm compresses to the legs to improve circulation.
• D. Massage the affected leg to relieve the pain.

Correct answer: B

Rationale: Clients with peripheral artery disease often experience claudication (leg pain during walking) due to decreased blood flow. Encouraging rest breaks during walking helps to manage pain and improve circulation. Rest breaks allow the muscles to recover from ischemia caused by inadequate blood supply. Increasing physical activity without breaks may worsen the symptoms. Applying warm compresses can potentially lead to burns or skin damage in individuals with compromised circulation. Massaging the affected leg is contraindicated in peripheral artery disease as it can further compromise blood flow.

4. A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. White blood cell count.
• B. Hemoglobin level.
• C. Serum creatinine level.
• D. Platelet count.

Correct answer: B

Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.

5. A client with a history of coronary artery disease is experiencing chest pain. What is the nurse's first action?

• A. Administer sublingual nitroglycerin
• B. Obtain a 12-lead electrocardiogram
• C. Call the healthcare provider
• D. Check the client's oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Administer sublingual nitroglycerin. Sublingual nitroglycerin is the first-line treatment for chest pain related to coronary artery disease. It helps dilate the coronary arteries and improve blood flow to the heart, providing immediate relief from ischemia. Administering nitroglycerin promptly can help alleviate the chest pain and prevent further complications. Obtaining a 12-lead electrocardiogram (Choice B) is important but should not delay the administration of nitroglycerin. Calling the healthcare provider (Choice C) can be done after initiating immediate treatment. Checking the client's oxygen saturation (Choice D) is relevant but not the first action to take in this scenario.
