1. 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.
2. The healthcare provider is caring for a client receiving total parenteral nutrition (TPN). Which laboratory value should be monitored closely to assess for complications?
- A. Serum sodium
- B. Serum calcium
- C. Blood urea nitrogen (BUN)
- D. Blood glucose
Correct answer: D
Rationale: The correct answer is D: Blood glucose. Monitoring blood glucose levels is crucial for clients receiving total parenteral nutrition (TPN) due to the high glucose content in TPN solutions. TPN delivers essential nutrients, including glucose, directly into the bloodstream. Clients on TPN are at risk of developing hyperglycemia due to the concentrated glucose infusion. Therefore, close monitoring of blood glucose levels is necessary to detect and prevent hyperglycemia-related complications such as osmotic diuresis, hyperosmolarity, and electrolyte imbalances. While serum sodium, serum calcium, and blood urea nitrogen (BUN) levels are important parameters in various clinical scenarios, they are not specifically associated with TPN administration. These values are not the primary indicators to assess for complications in clients receiving TPN.
3. A healthcare provider is delegating client care to assistive personnel. Which of the following tasks should the healthcare provider delegate?
- A. Evaluating healing of an incision
- B. Inserting an NG Tube
- C. Performing a simple dressing change
- D. Changing IV tubing
Correct answer: C
Rationale: The correct task that a healthcare provider should delegate to assistive personnel is performing a simple dressing change. Assistive personnel are trained and competent in performing basic wound care activities like simple dressing changes. Evaluating the healing of an incision requires clinical judgment and assessment skills that are typically performed by licensed healthcare professionals, such as nurses or physicians. Inserting an NG tube and changing IV tubing involve invasive procedures that require specialized training and skills, making them tasks that should be performed by licensed healthcare providers rather than assistive personnel.
4. The LPN/LVN is assisting with the care of a client who has had a stroke. Which intervention is most important to include in the client's plan of care to prevent joint contractures?
- A. Encourage the client to perform active range-of-motion exercises.
- B. Use pillows to keep the client's extremities in a functional position.
- C. Place the client in a prone position for 30 minutes each day.
- D. Perform passive range-of-motion exercises on the affected side.
Correct answer: B
Rationale: Using pillows to keep the client's extremities in a functional position is crucial in preventing joint contractures. This intervention helps maintain proper alignment of the joints and reduces the risk of contractures by preventing prolonged positioning that can lead to muscle shortening. Encouraging the client to perform active range-of-motion exercises (Choice A) is beneficial for maintaining mobility but may not be the most important intervention to prevent joint contractures. Placing the client in a prone position for 30 minutes each day (Choice C) can be helpful for preventing pressure ulcers but is not directly related to preventing joint contractures. Performing passive range-of-motion exercises on the affected side (Choice D) can aid in maintaining joint flexibility but may not be as crucial as using pillows to prevent joint contractures.
5. A healthcare provider is preparing to insert an IV catheter into a client's arm before starting IV fluid therapy. Which of the following interventions should the provider implement to prevent infection?
- A. Thread the IV catheter so that the hub rests at the insertion site
- B. Shave excess hair from around the insertion site
- C. Cleanse the site with hydrogen peroxide before IV catheter insertion
- D. Palpate the site carefully just before inserting the IV catheter
Correct answer: A
Rationale: Inserting the IV catheter so that the hub rests at the insertion site reduces the risk of contamination along the length of the catheter. This technique helps prevent introducing microbes into the bloodstream during the catheter insertion process. Shaving excess hair is unnecessary and can increase the risk of skin irritation and infection. Cleansing the site with hydrogen peroxide is outdated as it can cause tissue damage and delay wound healing. Palpating the site just before insertion can introduce bacteria from the skin surface into the insertion site, increasing the risk of infection.
