1. What is the most important action for the LPN/LVN to take to prevent infection in a client with an indwelling urinary catheter?
- A. Ensure the catheter tubing is free of kinks.
- B. Change the catheter every 72 hours.
- C. Clean the perineal area with an antiseptic solution daily.
- D. Irrigate the catheter with normal saline every shift.
Correct answer: A
Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.
2. A home health nurse is teaching a new caregiver how to care for a client who has had a tracheostomy for 1 year. Which of the following instructions should the nurse include?
- A. Use tracheostomy covers when going outdoors.
- B. Maintain sterile technique when performing tracheostomy care.
- C. Do not remove the outer cannula for routine cleaning.
- D. Clean around the stoma with normal saline.
Correct answer: A
Rationale: The correct answer is to use tracheostomy covers when going outdoors. This instruction is important as it helps protect the airway from dust and other particles, reducing the risk of infection or irritation. Choice B is incorrect because maintaining sterile technique is crucial during tracheostomy care to prevent infections, but it is not the most pertinent instruction in this scenario. Choice C is incorrect as removing the outer cannula is not a routine cleaning procedure and should only be done by healthcare professionals when necessary. Choice D is incorrect because cleaning around the stoma with normal saline is not recommended as it can cause irritation to the skin and stoma site.
3. A nurse is caring for a client receiving fluid through a peripheral IV catheter. Which of the following findings at the IV site should the nurse identify as infiltration?
- A. purulent exudate
- B. warmth
- C. skin blanching
- D. bleeding
Correct answer: C
Rationale: Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of entering the bloodstream properly. Skin blanching, swelling, and coolness at the IV site are typical signs of infiltration. Purulent exudate (choice A) is associated with infection, warmth (choice B) can indicate phlebitis, and bleeding (choice D) may occur if the IV catheter punctures a blood vessel.
4. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?
- A. 8 mL/hr
- B. 10 mL/hr
- C. 12 mL/hr
- D. 15 mL/hr
Correct answer: A
Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.
5. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:
- A. Cleanse the entry port prior to withdrawing urine.
- B. Use a sterile syringe to collect urine from the collection bag.
- C. Obtain the specimen from the drainage tubing.
- D. Replace the catheter before obtaining the specimen.
Correct answer: A
Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.
