Nursing Elites

1. A client with a history of atrial fibrillation is taking digoxin (Lanoxin). Which finding should the healthcare provider be notified of immediately?

• A. Heart rate of 52 beats per minute
• B. Blood pressure of 110/70 mmHg
• C. Blood glucose level of 180 mg/dL
• D. Potassium level of 4.0 mEq/L

Correct answer: A

Rationale: A heart rate of 52 beats per minute is a critical finding in a client taking digoxin, as it may indicate digoxin toxicity. Digoxin can cause bradycardia as a side effect, and a heart rate of 52 bpm warrants immediate attention to prevent adverse outcomes. Monitoring and reporting changes in heart rate are crucial in clients on digoxin therapy to prevent serious complications. The other vital signs and laboratory values provided are within normal ranges or not directly associated with digoxin toxicity in this scenario, making them lower priority for immediate reporting.

2. The LPN/LVN is assisting with the care of a client who has had a stroke. Which intervention is most important to include in the client's plan of care to prevent joint contractures?

• A. Encourage the client to perform active range-of-motion exercises.
• B. Use pillows to keep the client's extremities in a functional position.
• C. Place the client in a prone position for 30 minutes each day.
• D. Perform passive range-of-motion exercises on the affected side.

Correct answer: B

Rationale: Using pillows to keep the client's extremities in a functional position is crucial in preventing joint contractures. This intervention helps maintain proper alignment of the joints and reduces the risk of contractures by preventing prolonged positioning that can lead to muscle shortening. Encouraging the client to perform active range-of-motion exercises (Choice A) is beneficial for maintaining mobility but may not be the most important intervention to prevent joint contractures. Placing the client in a prone position for 30 minutes each day (Choice C) can be helpful for preventing pressure ulcers but is not directly related to preventing joint contractures. Performing passive range-of-motion exercises on the affected side (Choice D) can aid in maintaining joint flexibility but may not be as crucial as using pillows to prevent joint contractures.

3. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?

• A. Blood glucose of 350 mg/dL
• B. Serum bicarbonate of 18 mEq/L
• C. Arterial pH of 7.20
• D. Serum potassium of 5.5 mEq/L

Correct answer: C

Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.

4. A client with type 2 diabetes mellitus is receiving metformin (Glucophage). Which laboratory test should the LPN/LVN monitor while the client is taking this medication?

• A. Complete blood count (CBC)
• B. Liver function tests
• C. Serum electrolytes
• D. Renal function tests

Correct answer: B

Rationale: The correct answer is B: Liver function tests. While a client is taking metformin, monitoring liver function tests is crucial to assess for potential hepatic side effects. Metformin is primarily eliminated by the liver, and monitoring liver function tests helps in early detection of any liver-related complications. Choices A, C, and D are incorrect. A complete blood count (CBC) is not specifically required for monitoring metformin therapy. Serum electrolytes are not directly impacted by metformin, making it less relevant for monitoring this medication. Renal function tests are important for some other diabetes medications, but in the case of metformin, liver function tests take precedence due to its hepatic metabolism.

5. A nurse is preparing to insert an IV catheter for an adult client. Which of the following actions should the nurse take?

• A. Choose the most distal site on the selected extremity
• B. Apply a cool compress to the selected extremity before insertion of the IV catheter
• C. Stroke the selected extremity before insertion of the IV catheter
• D. Place the tourniquet above the proposed insertion site

Correct answer: C

Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.
