PN Exit Exam 2023 Quizlet
1. A client post-thyroidectomy is being monitored for signs of hypocalcemia. Which of the following symptoms should the nurse be most concerned about?
- A. Tingling in the hands and around the mouth.
- B. Nausea and vomiting.
- C. Constipation.
- D. Bradycardia.
Correct answer: A
Rationale: The correct answer is A: Tingling in the hands and around the mouth. This symptom is a classic sign of hypocalcemia, which can occur after thyroidectomy if the parathyroid glands were inadvertently damaged during surgery. Nausea and vomiting (Choice B) are not specific to hypocalcemia. Constipation (Choice C) is not a typical symptom of hypocalcemia. Bradycardia (Choice D) is more commonly associated with hypothyroidism rather than hypocalcemia.
2. The client diagnosed with HIV is taught by the nurse that the condition is transmitted through
- A. the infection passed from a mother to her baby
- B. Tears
- C. human bites
- D. insect bites
Correct answer: A
Rationale: HIV can be transmitted from a mother to her baby during childbirth or breastfeeding, making choice A the correct answer. Tears, human bites, and insect bites are not common modes of HIV transmission. While human bites can potentially transmit the virus, it is less common compared to mother-to-child transmission.
3. 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.
4. A nurse who receives a patient in the operative suite prior to the actual surgery is in charge of the patient’s care. Which of the following is NOT a task related to the nurse’s intraoperative care?
- A. Go over the surgical procedure with the patient before he or she is anesthetized
- B. Strictly adhere to asepsis during all intraoperative procedures
- C. Provide emotional support to the patient and their family
- D. Monitor the patient’s physical status
Correct answer: A
Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.
5. What is the primary cause of diabetic ketoacidosis (DKA)?
- A. Insulin deficiency
- B. Overhydration
- C. Excess carbohydrate intake
- D. Excess insulin
Correct answer: A
Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
