Nursing Elites

1. The healthcare provider prescribes an IV solution of isoproterenol (Isuprel) 1 mg in 250 ml of D5W at 300 mcg/hour. The nurse should program the infusion pump to deliver how many ml/hour?

• A. 50 ml/hour
• B. 25 ml/hour
• C. 75 ml/hour
• D. 100 ml/hour

Correct answer: C

Rationale: To calculate the infusion rate, convert 1 mg to 1,000 mcg (1 mg = 1,000 mcg) and then use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity of solution. In this case, it would be 300 mcg/hour / 1,000 mcg x 250 ml = 75 ml/hour. Therefore, the nurse should program the infusion pump to deliver 75 ml/hour. Choice A (50 ml/hour), Choice B (25 ml/hour), and Choice D (100 ml/hour) are incorrect as they do not correspond to the calculated rate of 75 ml/hour.

2. Before a dressing change to his legs, which intervention is most important for the nurse to implement?

• A. Encourage the patient to stay at the bedside
• B. Use distraction techniques to reduce pain
• C. Maintain strict aseptic technique
• D. Place a drape over the burn area

Correct answer: C

Rationale: Maintaining strict aseptic technique is crucial before a dressing change for burn patients to prevent infection. Encouraging the patient to stay at the bedside, using distraction techniques, or placing a drape over the burn area are not as critical as ensuring asepsis in this situation.

3. The nurse is caring for a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant in assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical in this scenario.

4. A client with liver cirrhosis is admitted with ascites and jaundice. Which assessment finding is most concerning?

• A. Serum albumin of 3.0 g/dL
• B. Bilirubin of 3.0 mg/dL
• C. Ammonia level of 80 mcg/dL
• D. Prothrombin time of 18 seconds

Correct answer: C

Rationale: An ammonia level of 80 mcg/dL is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to cognitive impairment, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are also important markers in liver cirrhosis but are not as directly associated with the risk of hepatic encephalopathy as elevated ammonia levels.

5. For the past 24 hours, an antidiarrheal agent, diphenoxylate, has been administered to a bedridden, older client with infectious gastroenteritis. Which finding requires the nurse to take further action?

• A. Tented skin turgor
• B. Decreased bowel sounds
• C. Persistent diarrhea
• D. Dehydration

Correct answer: A

Rationale: The correct answer is A. Tented skin turgor is a sign of dehydration, which can be exacerbated by the use of antidiarrheals in clients with gastroenteritis. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. Therefore, the nurse should take immediate action upon noticing tented skin turgor to prevent further complications. Choices B, C, and D are incorrect because decreased bowel sounds, persistent diarrhea, and dehydration are expected findings in a client with gastroenteritis who has been administered an antidiarrheal agent.
