Nursing Elites

1. A healthcare professional is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the healthcare professional review before administering the medication?

• A. Potassium
• B. Serum creatinine
• C. Sodium
• D. Hemoglobin A1C

Correct answer: B

Rationale: Correct Answer: The healthcare professional should review serum creatinine levels before administering metformin to assess kidney function. Metformin is excreted by the kidneys, and checking serum creatinine helps prevent lactic acidosis, a potential side effect in individuals with impaired renal function. Choice A: Potassium levels are not directly related to the administration of metformin. While monitoring potassium levels is important for some medications, it is not the priority when initiating metformin. Choice C: Sodium levels are not typically assessed specifically before starting metformin. It is not a routine lab test required prior to metformin administration. Choice D: Hemoglobin A1C reflects long-term blood sugar control and is not a lab test that needs to be reviewed before initiating metformin. It is used to monitor diabetes management over time, not for immediate medication administration considerations.

2. A nurse is planning care for a client who is 1 day postoperative following a total knee arthroplasty. Which of the following interventions should the nurse include?

• A. Keep the affected leg elevated as needed.
• B. Apply ice packs to the affected knee as prescribed.
• C. Encourage the client to ambulate as soon as possible.
• D. Perform range-of-motion exercises as instructed.

Correct answer: C

Rationale: Encouraging the client to ambulate as soon as possible is essential in preventing complications like deep vein thrombosis post knee arthroplasty. While keeping the affected leg elevated and applying ice packs can be beneficial in certain situations, early ambulation takes precedence in this case. Performing range-of-motion exercises hourly may not be necessary and could potentially cause more harm than good if not done correctly or excessively.

3. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

4. A healthcare professional is reviewing a client's admission laboratory results. Which of the following findings requires further evaluation?

• A. Sodium 138
• B. Creatinine 1.8
• C. Hemoglobin 15
• D. Potassium 4.2

Correct answer: B

Rationale: The correct answer is B. An elevated creatinine level, such as 1.8, suggests potential kidney dysfunction, requiring further assessment. Sodium level within normal limits (135-145 mEq/L), hemoglobin level of 15 g/dL, and potassium level of 4.2 mEq/L are all within normal ranges and do not indicate immediate concerns. Therefore, they do not require further evaluation at this time.

5. A client is postoperative following a hip arthroplasty. Which of the following interventions should the nurse include in the plan of care?

• A. Encourage the client to lie flat in bed.
• B. Apply heat to the incision site.
• C. Use an abduction pillow between the client's legs.
• D. Place a trochanter roll under the client's knees.

Correct answer: C

Rationale: Using an abduction pillow between the client's legs is essential in maintaining proper alignment and preventing dislocation of the hip joint following a hip arthroplasty. Encouraging the client to lie flat in bed (Choice A) is not recommended as early mobilization is crucial for preventing complications. Applying heat to the incision site (Choice B) is not typically done immediately postoperatively. Placing a trochanter roll under the client's knees (Choice D) is not as beneficial as using an abduction pillow to maintain proper positioning.
