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. Which task can the registered nurse (RN) caring for a critically ill patient with multiple IV lines delegate to an experienced licensed practical/vocational nurse (LPN/LVN)?
- A. Administer IV antibiotics through the implantable port.
- B. Monitor the IV sites for redness, swelling, or tenderness.
- C. Remove the patient’s nontunneled subclavian central venous catheter.
- D. Adjust the flow rate of the 0.9% normal saline in the peripheral IV line.
Correct answer: B
Rationale: An experienced LPN/LVN can monitor IV sites for signs of infection because it falls within their education, experience, and scope of practice. Administering IV antibiotics through an implantable port, adjusting infusion rates, and removing central catheters are tasks that require RN level education and scope of practice. These activities involve a higher level of assessment, critical thinking, and potential complications that are typically within the RN's domain.
3. A nurse in the outpatient clinic is caring for a patient who has a magnesium level of 1.3 mg/dL. Which assessment would be most important for the nurse to make?
- A. Daily alcohol intake
- B. Intake of dietary protein
- C. Multivitamin/mineral use
- D. Use of over-the-counter (OTC) laxatives
Correct answer: A
Rationale: The correct answer is A: Daily alcohol intake. Hypomagnesemia is often associated with alcoholism, making it crucial for the nurse to assess the patient's alcohol consumption. Protein intake is not directly related to magnesium levels. The use of over-the-counter laxatives and multivitamin/mineral supplements would typically increase magnesium levels, which are not the focus when dealing with hypomagnesemia.
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. The nurse requests a meal tray for a client who follows Mormon beliefs and who is on a clear liquid diet following abdominal surgery. Which menu items should the nurse request for this client? (Select all that apply)
- A. apple juice
- B. black coffee
- C. orange juice
- D. hot chocolate
Correct answer: A
Rationale: The correct answer is A: apple juice. Clear liquids like apple juice and orange juice are suitable for a client following a clear liquid diet and Mormon beliefs. Options B and D, black coffee and hot chocolate, contain caffeine, which may not align with the client's religious dietary restrictions. Therefore, these options should be avoided for this client.
