Nursing Elites

1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the LPN/LVN set the client's intravenous infusion pump?

• A. 13 ml/hour
• B. 63 ml/hour
• C. 80 ml/hour
• D. 125 ml/hour

Correct answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

2. 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.

3. The nurse is assessing a client who has just been admitted with a diagnosis of acute pancreatitis. Which finding is most important for the LPN/LVN to report to the healthcare provider immediately?

• A. Elevated serum lipase level
• B. Severe abdominal pain
• C. Nausea and vomiting
• D. Hypotension

Correct answer: D

Rationale: Hypotension is a critical finding that should be reported immediately in a client with acute pancreatitis as it may indicate severe complications such as hemorrhage or shock. While elevated serum lipase level, severe abdominal pain, and nausea/vomiting are common manifestations of acute pancreatitis, hypotension is a more urgent sign requiring immediate attention to prevent further deterioration. Hypotension can be a sign of significant fluid loss, hemorrhage, or sepsis, which are potentially life-threatening conditions that need prompt intervention. Elevated serum lipase levels, severe abdominal pain, and nausea/vomiting are important in the assessment of pancreatitis but do not indicate the same level of immediate danger as hypotension does.

4. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Blood urea nitrogen (BUN) of 45 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

5. A nurse manager is reviewing with nurses on the unit the care of a client who has had a seizure. Which of the following statements by a nurse requires further instruction?

• A. “I will place the client on their side.”
• B. “I will go to the nurses’ station for assistance.”
• C. “I will note the time that the seizure begins.”
• D. “I will prepare to insert an airway.”

Correct answer: B

Rationale: The correct answer is B. Going to the nurses’ station for assistance during a seizure is inappropriate as immediate care is necessary. Placing the client on their side helps maintain an open airway and prevents aspiration. Noting the time the seizure begins is crucial for monitoring and documentation. Preparing to insert an airway may be necessary if the client's airway becomes compromised. Therefore, the nurse's statement about going to the nurses' station for assistance is the only incorrect response as it delays essential care.
