ATI RN Fundamentals Exam 3 Questions
Extract:
Question 1 of 5
A client will require IV antibiotics for several weeks. Which venous access device would be most appropriate to be used for this client?
Correct Answer: B
Rationale: The correct answer is B, a peripherally inserted central catheter (PIC
C), for a client requiring long-term IV antibiotics. A PICC line is ideal as it provides central venous access, minimizing irritation to peripheral veins. It allows for long-term use without frequent insertion, reducing the risk of infection. The other options are not suitable: A butterfly needle is for short-term use, a peripheral IV-lock is not appropriate for prolonged antibiotics, and a small gauge peripheral angiocath may not be durable for long-term use.
Question 2 of 5
A client requires an IV antibiotic piggyback. The nurse understands that the primary IV solution with gravity flow tubing needs to be hung:
Correct Answer: A
Rationale: The correct answer is A: higher than the piggyback medication. This is because when the primary IV solution is hung higher than the piggyback medication, it allows gravity to assist in infusing the piggyback medication after the primary infusion is completed. This ensures that the piggyback medication is delivered effectively and prevents backflow into the primary line. Hanging the primary IV solution lower than the piggyback medication (option
B) would not provide the necessary gravity flow for the piggyback medication. Placing the primary IV solution at the same height as the piggyback bag (option
C) would not allow for proper infusion sequencing. Hanging the primary IV solution lower than the IV insertion site (option
D) could lead to infiltration or occlusion.
Question 3 of 5
The nurse assessing a client's intravenous catheter site suspects a phlebitis based on which clinical findings?
Correct Answer: A
Rationale: The correct answer is A because warmth and palpable cord along the vein indicate inflammation of the vein, which is characteristic of phlebitis. Option B describes a hematoma, not phlebitis. Option C suggests localized edema, not phlebitis. Option D describes pallor, not characteristic of phlebitis.
Question 4 of 5
A nurse is about to administer a bolus enteral feeding to a client who is on bedrest. How does the nurse position the client during the feeding?
Correct Answer: B
Rationale: The correct answer is B: With the head of the bed elevated 30-45 degrees. This position helps prevent aspiration during enteral feeding by promoting proper digestion and reducing the risk of reflux. Elevating the head of the bed facilitates the flow of the feeding formula and minimizes the chances of regurgitation. Placing the client on the left or right side with knees bent or with a pillow behind the back does not directly address the risk of aspiration or promote proper digestion. Elevating the head of the bed to 15 degrees is not high enough to effectively prevent aspiration.
Question 5 of 5
A nurse caring for a client who has a peripheral intravenous saline lock understands that its purpose is to:
Correct Answer: C
Rationale: The correct answer is C: establish a venous route for clients when their condition changes. A saline lock, also known as a heparin lock, is a type of intravenous access device that allows for intermittent access to a vein without the need for a continuous infusion. This is useful for clients whose condition may require medications or fluids intermittently without the need for a continuous IV drip. Option A is incorrect because a saline lock is not specifically designed for highly irritating or hyperosmolar solutions. Option B is incorrect as the primary purpose of a saline lock is not to draw blood for laboratory tests. Option D is incorrect because while a saline lock can be used for short-term IV antibiotic administration, its primary purpose is not for prolonged antibiotic therapy.
