Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Prothrombin time (PT)
• B. Hemoglobin level
• C. International Normalized Ratio (INR)
• D. Serum sodium level

Correct answer: C

Rationale: The correct answer is C, International Normalized Ratio (INR). The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps ensure that the client is within the therapeutic range for anticoagulation, reducing the risk of bleeding or clotting complications. Prothrombin time (A) is used to calculate the INR and monitor the effectiveness of warfarin therapy. Hemoglobin level (B) is important but not the primary lab value to monitor when a client is on warfarin. Serum sodium level (D) is not directly related to monitoring warfarin therapy.

2. 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.

3. The nurse is caring for a client with acute pancreatitis who is receiving total parenteral nutrition (TPN). Which laboratory value should be monitored closely?

• A. Serum calcium
• B. Serum triglycerides
• C. Serum glucose
• D. Serum triglycerides

Correct answer: B

Rationale: Serum triglycerides should be monitored closely in a client receiving TPN as they may indicate hyperlipidemia, which is a potential complication of TPN. Monitoring serum triglycerides is essential to prevent complications such as hypertriglyceridemia. Serum calcium and glucose levels are also important to monitor in clients receiving TPN, but in this scenario, serum triglycerides take priority due to the risk of hyperlipidemia.

4. A mother brings her 6-year-old child, who has just stepped on a rusty nail, to the pediatrician's office. Upon inspection, the nurse notes that the nail went through the shoe and pierced the bottom of the child's foot. Which action should the nurse implement first?

• A. Cleanse the foot with soap and water and apply an antibiotic ointment
• B. Provide teaching about the need for a tetanus booster within the next 72 hours.
• C. Have the mother check the child's temperature every 4 hours for the next 24 hours
• D. Transfer the child to the emergency department to receive a gamma globulin injection

Correct answer: A

Rationale: The correct first action for the nurse to implement is to cleanse the foot with soap and water and apply an antibiotic ointment to prevent infection. In cases of puncture wounds like stepping on a rusty nail, the immediate concern is to reduce the risk of infection. Providing teaching about the need for a tetanus booster within the next 72 hours is important as well, but it should come after the wound is cleansed. Checking the child's temperature and transferring to the emergency department for a gamma globulin injection are not the immediate priorities in this scenario.

5. A 7-year-old boy is brought to the clinic because of facial edema. He reports that he has been voiding small amounts of dark, cloudy, tea-colored urine. The parents state that their son had a sore throat 2 weeks earlier, but it has resolved. After assessing the child's vital signs and weight, what intervention should the nurse implement next?

• A. Perform an otoscopic examination
• B. Measure the child's abdominal girth
• C. Collect a urine specimen for routine urinalysis
• D. Obtain a blood specimen for serum electrolytes

Correct answer: C

Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.
