Nursing Elites

1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?

• A. Serum potassium
• B. Serum calcium
• C. Serum albumin
• D. Serum sodium

Correct answer: C

Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.

2. When assessing the skin of an immobilized patient, what should the nurse do?

• A. Assess the skin every 4 hours.
• B. Limit the amount of fluid intake.
• C. Use a standardized tool such as the Braden Scale.
• D. Have special times for inspection to not interrupt routine care.

Correct answer: C

Rationale: When assessing the skin of an immobilized patient, it is essential to use a standardized tool like the Braden Scale. This tool helps in systematically evaluating the patient's risk of developing pressure ulcers. Assessing the skin every 4 hours (Choice A) may be too frequent or unnecessary unless there are specific concerns or orders. Limiting fluid intake (Choice B) is not directly related to skin assessment in an immobilized patient. Having special times for inspection to avoid interrupting routine care (Choice D) is not as crucial as using a standardized tool for consistent and comprehensive skin assessment.

3. What action should be taken to maintain the patency of a peripherally inserted central catheter (PICC)?

• A. Flush the catheter with heparin solution daily.
• B. Change the dressing at the insertion site daily.
• C. Use sterile technique when changing the dressing.
• D. Keep the insertion site dry at all times.

Correct answer: C

Rationale: The correct answer is to use sterile technique when changing the dressing. This practice is essential for preventing infections that can compromise the patency of the PICC line. While flushing the catheter with heparin solution helps prevent clot formation, it does not directly maintain patency. Changing the dressing daily is important for hygiene but does not have a direct impact on catheter patency. Keeping the insertion site dry is crucial to prevent infections but does not specifically address patency maintenance.

4. The nurse is caring for a client who is receiving 24-hour total parenteral nutrition (TPN) via a central line at 54 ml/hr. When initially assessing the client, the nurse notes that the TPN solution has run out and the next TPN solution is not available. What immediate action should the nurse take?

• A. Infuse normal saline at a keep-vein-open rate.
• B. Discontinue the IV and flush the port with heparin.
• C. Infuse 10% dextrose and water at 54 ml/hr.
• D. Obtain a stat blood glucose level and notify the healthcare provider.

Correct answer: C

Rationale: Infusing 10% dextrose and water at 54 ml/hr is the correct action to prevent hypoglycemia until the next TPN solution becomes available. This solution will help maintain the client's glucose levels. Infusing normal saline at a keep-vein-open rate (Choice A) is not appropriate for maintaining glucose levels and would not address the nutritional needs provided by TPN. Discontinuing the IV and flushing the port with heparin (Choice B) is unnecessary and not indicated in this situation as the client still needs fluid and nutrition. Obtaining a stat blood glucose level and notifying the healthcare provider (Choice D) can be done later but is not the immediate action required when the TPN solution has run out.

5. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?

• A. pH below 7.3
• B. Potassium of 5.0
• C. HCT of 60
• D. PaO2 of 79%

Correct answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
