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 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.

3. A male client with unstable angina needs a cardiac catheterization. So the healthcare provider explains the risks and benefits of the procedure and then leaves to set up for the procedure. When the nurse presents the consent form for signature, the client hesitates and asks how the wires will keep his heart going. Which action should the nurse take?

• A. Answer the client's specific questions with a short, understandable explanation
• B. Postpone the procedure until the client understands the risks and benefits
• C. Call the client's next of kin and ask them to provide verbal consent
• D. Page the healthcare provider to return and provide additional explanation

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to page the healthcare provider to return and provide additional explanation. It is crucial for the client to have a clear understanding of the procedure, including its risks and benefits, before signing the consent form. While the nurse can provide general information, the detailed explanation of how the procedure works and its effects should come from the healthcare provider who will perform the procedure. Postponing the procedure until the client understands is appropriate, but the immediate need is to clarify the client's concerns with the healthcare provider. Calling the client's next of kin for verbal consent is not the correct course of action as the client is present and able to provide consent after receiving adequate information.

4. A patient receives 3% NaCl solution for correction of hyponatremia. Which assessment is most important for the nurse to monitor while the patient is receiving this infusion?

• A. Lung sounds
• B. Urinary output
• C. Peripheral pulses
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Lung sounds. Hypertonic solutions like 3% NaCl can cause water retention, leading to fluid excess. Monitoring lung sounds is crucial as crackles may indicate pulmonary edema, a serious manifestation of fluid excess. While monitoring urinary output, peripheral pulses, and peripheral edema are also important when administering hypertonic solutions, they do not provide immediate clues to acute respiratory or cardiac decompensation like lung sounds.

5. A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?

• A. blood transfusion
• B. chemotherapy
• C. bone marrow transplantation
• D. immunosuppressive therapy

Correct answer: C

Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.
