HESI PN Exit Exam 2024 Quizlet
1. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the PN to review?
- A. Hemoglobin and Hematocrit
- B. Serum Calcium
- C. Serum Creatinine
- D. WBC
Correct answer: C
Rationale: Serum creatinine is the most important lab value to review before administering an antibiotic that can cause nephrotoxicity. This is because serum creatinine is a key indicator of kidney function. An elevated serum creatinine level may indicate impaired renal function, and administering nephrotoxic drugs in such situations can further damage the kidneys. Monitoring serum creatinine levels helps healthcare providers assess renal function and make informed decisions regarding drug administration. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity, making them less crucial in this scenario. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels are more related to bone health and nerve function, and WBC count is associated with immune response, none of which directly reflect kidney function or the risk of nephrotoxicity.
2. Which of the following is the most effective way to prevent the spread of infection in a healthcare setting?
- A. Using sterile gloves
- B. Wearing a face mask
- C. Performing hand hygiene
- D. Using disposable equipment
Correct answer: C
Rationale: Performing hand hygiene is the most effective way to prevent the spread of infection in a healthcare setting. Hand hygiene helps remove pathogens that could be transmitted through direct contact, making it a crucial practice in infection control. While using sterile gloves and disposable equipment are important in certain situations, they do not address the potential transmission of pathogens through direct contact, unlike hand hygiene. Wearing a face mask is important for respiratory precautions but may not be as effective as hand hygiene in preventing the spread of infections through direct contact.
3. What is the most appropriate nursing action when a patient on anticoagulant therapy develops sudden, severe back pain?
- A. Administer pain medication
- B. Apply a cold compress to the back
- C. Assess for signs of internal bleeding
- D. Reposition the patient for comfort
Correct answer: C
Rationale: When a patient on anticoagulant therapy experiences sudden, severe back pain, the priority nursing action is to assess for signs of internal bleeding. Severe back pain in this context could be indicative of internal bleeding, such as a retroperitoneal bleed, which is a critical condition requiring immediate attention. Administering pain medication or applying a cold compress may mask or delay the identification of a potentially life-threatening situation. Repositioning the patient for comfort is not the priority when internal bleeding needs to be ruled out.
4. The PN reviews a client's medication history and learns that the client takes an anticoagulant and has recently started taking phenytoin. Which instruction should the PN provide when assigning the client's morning care to a UAP?
- A. Measure the temperature every 4 hours
- B. Elevate both feet on two pillows
- C. Initiate hourly turning schedule
- D. Protect skin from injury and bruising
Correct answer: D
Rationale: The correct answer is D: Protect skin from injury and bruising. Phenytoin and anticoagulants both increase the risk of bleeding. Protecting the skin from injury and bruising is critical to prevent complications, making it important to instruct the UAP accordingly. Measuring the temperature every 4 hours (Choice A) may not be directly related to the client's medications. Elevating both feet on two pillows (Choice B) is more relevant for issues like edema. Initiating an hourly turning schedule (Choice C) is important for preventing pressure ulcers, but in this case, the priority is to prevent bleeding due to the medications.
5. A client with a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management asks how it works. What information should the nurse reinforce?
- 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 that can block pain signals from reaching the brain, effectively reducing the perception of pain. Choice A is incorrect because TENS does not distract from pain but rather interferes with pain signals. Choice B is incorrect as TENS does not involve infusing medication into the spinal canal. Choice C is also incorrect because TENS does not target the cerebral cortex to dull pain perception but rather works at the level of nerve conduction.
