Nclex Exam Cram Practice Questions
1. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?
- A. Brown-S�quard syndrome
- B. posterior cord syndrome
- C. central cord syndrome
- D. cauda equina syndrome
Correct answer: A
Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.
2. The advanced directive in a client's chart is dated August 12, 1998. The client's daughter produces a Power of Attorney for Health Care, dated 2003, which contains different care directions. What should the nurse do?
- A. Follow the 1998 version because it's part of the legal chart.
- B. Follow the 1998 version because the physician's code order is based on it.
- C. Follow the 2003 version, place it in the chart, and communicate the update appropriately.
- D. Follow neither until clarified by the unit manager.
Correct answer: C
Rationale: The document dated 2003 supersedes the previous version and should be used as a basis for care directions. The nurse should follow the 2003 version, place it in the chart, and communicate the update appropriately to ensure that the most current care directions are followed. Choices A and B are incorrect because the 1998 version is now outdated, and the nurse should not rely on it for care decisions. Choice D is incorrect because the nurse should not delay following the updated document, and seeking clarification from the unit manager can lead to avoidable delays in care.
3. The LPN is auscultating for bowel sounds and hears between 3 and 4 bowel sounds per minute. This is a somewhat expected finding for which of these clients?
- A. a 63-year-old female undergoing chemotherapy for breast cancer
- B. a 56-year-old female with dementia undergoing a swallow study
- C. a 34-year-old male with a PEG tube newly admitted for diabetic ketoacidosis
- D. a 45-year-old male recovering from a knee replacement under general anesthesia
Correct answer: D
Rationale: When recovering from general anesthesia, hypoactive bowel sounds can be expected due to the effects of the anesthesia on gut motility. For the other clients, hearing less than 5 bowel sounds per minute would indicate an abnormal finding. In the context of the given situation, the client recovering from knee replacement surgery aligns with the expected range of bowel sounds post-general anesthesia. Therefore, choice D is the correct answer. Choices A, B, and C present scenarios where hearing less than 5 bowel sounds per minute would be abnormal, indicating potential issues that need further evaluation.
4. A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture
- D. marginal finding.
Correct answer: A
Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.
5. After undergoing gastric resection, the client is informed by the nurse that which of the following meals is most likely to cause rapid emptying of the stomach?
- A. a high-protein meal
- B. a high-fat meal
- C. a large meal regardless of nutrient content
- D. a high-carbohydrate meal
Correct answer: D
Rationale: After gastric resection, meals high in carbohydrates are more likely to cause rapid emptying of the stomach. Carbohydrates stimulate the release of gastrin, which accelerates gastric emptying. On the other hand, high-fat and high-protein meals tend to delay gastric emptying. A large meal, regardless of nutrient content, can also delay gastric emptying due to the increased volume of food that needs to be processed.
