HESI PN Exit Exam 2023
1. A client post-thoracotomy is complaining of severe pain with deep breathing and coughing. What should the nurse encourage the client to do to manage the pain and prevent respiratory complications?
- A. Hold a pillow against the chest while coughing (splinting).
- B. Take shallow breaths to avoid pain.
- C. Increase the dose of pain medication.
- D. Avoid deep breathing exercises.
Correct answer: A
Rationale: Splinting the chest with a pillow helps manage pain during deep breathing and coughing, which is essential to prevent respiratory complications such as atelectasis or pneumonia after thoracic surgery. Holding a pillow against the chest while coughing (splinting) supports the incision site and reduces the pain associated with deep breathing and coughing. Encouraging shallow breaths (Choice B) can lead to respiratory complications due to inadequate lung expansion. Increasing pain medication (Choice C) should be done based on healthcare provider orders and not solely for this situation. Avoiding deep breathing exercises (Choice D) can worsen respiratory function and increase the risk of complications.
2. 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 nurse reinforce about the action of this adjuvant pain modality?
- A. The discharge of electricity will distract the client's focus from the pain
- B. An infusion of medication in the spinal canal will block pain perception
- C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
Correct answer: D
Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.
3. When preparing a sterile field for a procedure, which action should the nurse take to maintain sterility?
- A. Place sterile items around the sterile field
- B. Keep hands below waist level to avoid contamination
- C. Open the sterile package away from the body
- D. Avoid reaching over the sterile field
Correct answer: D
Rationale: To maintain sterility when preparing a sterile field, it is essential to avoid reaching over the sterile field. This action can introduce contaminants from the nurse's clothing or unsterile areas, compromising the sterility of the field. Placing sterile items around the sterile field (choice A) is incorrect as it may increase the risk of contamination by extending the area where non-sterile items may come in contact. Keeping hands below waist level (choice B) is also incorrect as it does not prevent contamination effectively. Opening the sterile package away from the body (choice C) is incorrect since it exposes the contents to the nurse's body, which is not sterile.
4. Which action should the PN implement when using standard precautions to provide client care?
- A. Apply sterile gloves to obtain a finger stick blood sample
- B. Wear clean exam gloves to perform perineal catheter care
- C. Replace the needle cap after giving an intramuscular injection
- D. Wear a paper gown to prevent transmission of droplet pathogens
Correct answer: B
Rationale: The correct answer is B. When using standard precautions, healthcare providers should wear clean exam gloves to perform perineal catheter care. This approach helps prevent the transmission of pathogens and ensures the safety of both the client and the healthcare provider. Choice A is incorrect because applying sterile gloves for a finger stick blood sample is unnecessary when non-sterile gloves would suffice. Choice C is incorrect because replacing the needle cap after giving an intramuscular injection is not directly related to standard precautions. Choice D is incorrect because wearing a paper gown is not a standard precaution for preventing the transmission of droplet pathogens.
5. Which condition is characterized by a progressive loss of muscle strength due to an autoimmune attack on acetylcholine receptors?
- A. Myasthenia gravis
- B. Multiple sclerosis
- C. Amyotrophic lateral sclerosis
- D. Guillain-Barré syndrome
Correct answer: A
Rationale: The correct answer is A: Myasthenia gravis. Myasthenia gravis is characterized by muscle weakness caused by autoimmune attack on acetylcholine receptors at the neuromuscular junction. This results in impaired communication between nerves and muscles. Choice B, Multiple sclerosis, is a condition where the immune system attacks the protective myelin sheath covering the nerves in the central nervous system, leading to communication issues between the brain and the rest of the body. Choice C, Amyotrophic lateral sclerosis, is a progressive neurodegenerative disease affecting motor neurons in the brain and spinal cord, not involving acetylcholine receptors. Choice D, Guillain-Barré syndrome, is an acute condition where the immune system attacks the peripheral nerves, causing muscle weakness and paralysis, but it does not target acetylcholine receptors.
