Nursing Elites

1. A patient has a parenteral nutrition infusion of 25% dextrose. A student nurse asks the nurse why a peripherally inserted central catheter was inserted. Which response by the nurse is most appropriate?

• A. There is a decreased risk for infection when 25% dextrose is infused through a central line.
• B. The prescribed infusion can be given much more rapidly when the patient has a central line.
• C. The 25% dextrose is hypertonic and will be more rapidly diluted when given through a central line.
• D. The required blood glucose monitoring is more accurate when samples are obtained from a central line.

Correct answer: C

Rationale: The 25% dextrose solution is hypertonic. Shrinkage of red blood cells can occur when solutions with dextrose concentrations greater than 10% are administered IV. Blood glucose testing is not more accurate when samples are obtained from a central line. The infection risk is higher with a central catheter than with peripheral IV lines. Hypertonic or concentrated IV solutions are not given rapidly.

2. A patient is admitted for hypovolemia associated with multiple draining wounds. Which assessment would be the most accurate way for the nurse to evaluate fluid balance?

• A. Skin turgor
• B. Daily weight
• C. Presence of edema
• D. Hourly urine output

Correct answer: B

Rationale: Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age and can be affected by various factors other than fluid balance. Presence of edema indicates excess fluid has moved into the interstitial space, which may not always be directly correlated with overall fluid balance. Hourly urine outputs, though important, do not provide a comprehensive picture of fluid balance as they do not consider fluid intake, insensible losses, or other sources of fluid loss.

3. A patient comes to the clinic complaining of frequent, watery stools for the last 2 days. Which action should the nurse take first?

• A. Obtain the baseline weight
• B. Check the patient’s blood pressure
• C. Draw blood for serum electrolyte levels
• D. Ask about any extremity numbness or tingling

Correct answer: B

Rationale: The correct answer is to check the patient’s blood pressure. Given the patient's symptoms of frequent, watery stools, there is a concern for fluid volume deficit. Assessing the blood pressure helps determine the patient's perfusion status, which is crucial in managing fluid volume deficits. While obtaining baseline weight, drawing blood for serum electrolyte levels, and asking about extremity numbness or tingling are important assessments, checking the blood pressure takes precedence as it provides immediate information on the patient's circulatory status.

4. A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient complains of "just blowing up" and has peripheral edema and shortness of breath. Which assessment should the nurse complete first?

• A. Skin turgor
• B. Heart sounds
• C. Mental status
• D. Capillary refill

Correct answer: C

Rationale: Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds also may be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.

5. Before leaving the room of a confused client, the nurse notes that a half bow knot was used to attach the client's wrist restraints to the movable portion of the client's bed frame. What action should the nurse take before leaving the room?

• A. Tie the knot with a double turn or square knot
• B. Ensure that the restraints are snug against the client's wrists
• C. Ensure that the knot can be quickly released
• D. Move the ties so the restraints are secured to the side rails

Correct answer: C

Rationale: The priority is to ensure that the knot can be quickly released to allow for quick intervention if necessary. Tying the knot with a double turn or square knot (Choice A) may make it more difficult to release quickly in an emergency. Ensuring that the restraints are snug against the client's wrists (Choice B) may compromise circulation and cause discomfort. Moving the ties to secure the restraints to the side rails (Choice D) is not the appropriate action as it can limit the client's movement and access to care.
