HESI PN Exit Exam 2024 Quizlet
1. What is the most common sign of a localized infection?
- A. Fever
- B. Elevated white blood cell count
- C. Redness, warmth, and swelling at the site of infection
- D. Chills and shivering
Correct answer: C
Rationale: The correct answer is C: Redness, warmth, and swelling at the site of infection. These signs are typical indications of a localized infection, representing inflammation and the body's immune response to the pathogen. Fever (choice A) is a systemic response and not specific to a localized infection. Elevated white blood cell count (choice B) can be seen in both localized and systemic infections. Chills and shivering (choice D) are more related to the body's response to fever and not specifically indicative of a localized infection.
2. The patient diagnosed with athlete's foot (tinea pedis) states that he is relieved because it is only athlete's foot, and it can be treated easily. Which information about this condition should the nurse consider when formulating a response to the patient?
- A. It is contagious with frequent recurrences.
- B. It is most helpful to air-dry feet after bathing.
- C. It is treated with salicylic acid.
- D. It is caused by lice.
Correct answer: A
Rationale: Athlete's foot, also known as tinea pedis, is a contagious fungal infection that can easily spread to other body parts, particularly the hands. It often recurs if not properly treated, making choice A the correct answer. Choices B and C are incorrect because while it is beneficial to air-dry feet after bathing to prevent moisture buildup, athlete's foot is commonly treated with antifungal medications, not salicylic acid. Choice D is incorrect because athlete's foot is caused by a fungal infection, not lice.
3. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?
- A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
- B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- C. An infusion of medication in the spinal canal will block pain perception
- D. The discharge of electricity will distract the client's focus on the pain
Correct answer: A
Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.
4. A client with hypertension is prescribed valsartan. The nurse should monitor the client for which potential side effect?
- A. Hypotension
- B. Tachycardia
- C. Hyperglycemia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Hypotension. Valsartan is an angiotensin II receptor blocker that can cause hypotension as a side effect by dilating blood vessels. Monitoring blood pressure is crucial to prevent complications related to low blood pressure. Choice B, Tachycardia, is incorrect because valsartan typically does not cause an increase in heart rate. Choice C, Hyperglycemia, is not a common side effect of valsartan. Choice D, Hyponatremia, is also unlikely with valsartan use.
5. What behavior does a toddler subjected to prolonged hospitalization with limited parental visits typically exhibit?
- A. Engage in cheerful interactions with staff members
- B. Display indications of sadness throughout the day
- C. Experience excessive crying when parents are not present
- D. Show limited emotional response to the environment
Correct answer: D
Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits usually exhibit a limited emotional response to the environment. This behavior can be a coping mechanism for the child in dealing with the separation from their primary caregivers. The child might not show the same level of engagement or emotional expression as they would if their parents were present. Choices A, B, and C are less likely because the child's emotional response is typically more subdued and withdrawn in such circumstances, rather than being cheerful, consistently sad, or excessively crying.
