PN Exit Exam 2023 Quizlet Questions
Question 1 of 5
A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the PN reinforce about the action of the adjuvant pain modality?
Correct Answer: D
Rationale: The TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.
Question 2 of 5
The UAP reports to the PN that a client refused to bathe for the third consecutive day. Which action is best for the PN to take?
Correct Answer: D
Rationale: The best action for the PN to take when a client refuses to bathe is to ask the client why the bath was refused. Understanding the client's reasons for refusing a bath is crucial as it helps to address any underlying issues, such as fear, discomfort, or physical limitations. By communicating directly with the client, the PN can provide appropriate care tailored to the client's needs. Choices A, B, and C do not directly address the root cause of the refusal and may not effectively resolve the issue.
Question 3 of 5
According to the principle of asepsis, which situation should the PN consider to be sterile?
Correct Answer: A
Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.
Question 4 of 5
An adult female client with type 1 diabetes mellitus is receiving NPH insulin 35 units in the morning. Which finding should the PN document as evidence that the amount of insulin is inadequate?
Correct Answer: C
Rationale: The correct answer is C. High evening glucose levels indicate that the morning dose of NPH insulin may be insufficient to control blood sugar throughout the day. Choice A is incorrect as cold and numb feet are more indicative of a circulation issue rather than an insulin inadequacy. Choice B suggests a wound infection rather than inadequate insulin. Choice D, nausea in the morning, may be due to other causes and does not necessarily indicate inadequate insulin dosage.
Question 5 of 5
After a hip replacement surgery, a client is instructed to use an abduction pillow while in bed. What is the primary purpose of this device?
Correct Answer: B
Rationale: The primary purpose of using an abduction pillow after hip replacement surgery is to prevent hip dislocation. The abduction pillow keeps the legs separated, which reduces the risk of hip dislocation by preventing excessive internal rotation and adduction of the hip joint. Choices A, C, and D are incorrect as the main goal of using the abduction pillow is to maintain proper positioning and stability of the hip joint to prevent dislocation, rather than addressing blood clots, circulation, or pain relief.
