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. How should the nurse interpret the following arterial blood gas results for a patient who had a tracheostomy placed after a motor vehicle crash: pH 7.48, PaO2 85 mm Hg, PaCO2 32 mm Hg, and HCO3 25 mEq/L?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: D

Rationale: The patient's pH of 7.48 indicates alkalosis, and the low PaCO2 of 32 mm Hg suggests a respiratory cause. The HCO3 level is normal, ruling out metabolic causes. Therefore, the correct interpretation is respiratory alkalosis. Options A, B, and C are incorrect as they do not align with the pH and PaCO2 values provided.

3. 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.

4. The nurse is teaching the parent of a child newly diagnosed with a latex allergy. Which information by the parents indicates a need for further teaching?

• A. Rubber-free toys, such as wooden building blocks, are good choices for the child.
• B. Only foil balloons will be used for the child's birthday party.
• C. A diet of healthy fruits, such as bananas and kiwis, is best for the child.
• D. An epinephrine auto-injector will be on hand to treat allergic reactions.

Correct answer: C

Rationale: The correct answer is C. Bananas and kiwis are foods that can cross-react with latex allergy, indicating that the parents need further teaching on managing latex allergies. Choices A, B, and D are correct as rubber-free toys, using foil balloons, and having an epinephrine auto-injector are appropriate measures to prevent and manage allergic reactions in a child with a latex allergy.

5. The nurse is caring for a patient who has a central venous access device (CVAD). Which action by the nurse is appropriate?

• A. Avoid using friction when cleaning around the CVAD insertion site.
• B. Use the push-pause method to flush the CVAD after giving medications.
• C. Obtain an order from the healthcare provider to change the CVAD dressing.
• D. Position the patient’s face away from the CVAD during injection cap changes.

Correct answer: B

Rationale: The correct answer is B because using the push-pause method to flush the CVAD after giving medications helps remove debris from the CVAD lumen and decreases the risk for clotting. Choice A is incorrect because friction should be used when cleaning the CVAD insertion site to decrease infection risk. Choice C is incorrect because obtaining an order from the healthcare provider to change the CVAD dressing is not necessary; the dressing should be changed when damp, loose, or visibly soiled. Choice D is incorrect because the patient should face away from the CVAD during cap changes to minimize the risk of contamination.
