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. Which of the following medications might cause upper-gastrointestinal (UGI) bleeding?
- A. Cardizem (diltiazem)
- B. Naprosyn (naproxen)
- C. Elavil (amitriptyline)
- D. Corgard (nadolol)
Correct answer: C
Rationale: Naprosyn (naproxen) is known to cause upper-gastrointestinal (UGI) bleeding due to its effects on the stomach lining. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can irritate the stomach and increase the risk of UGI bleeding. On the other hand, Cardizem (diltiazem), Elavil (amitriptyline), and Corgard (nadolol) are not typically associated with UGI bleeding. Cardizem is a calcium channel blocker used for hypertension and angina, Elavil is a tricyclic antidepressant, and Corgard is a beta-blocker used for hypertension.
3. What is the most appropriate feeding method for a client who is unable to swallow?
- A. Nothing by mouth
- B. Nasogastric feedings
- C. Clear liquids
- D. Total parenteral nutrition
Correct answer: B
Rationale: Nasogastric feedings are the most appropriate feeding method for a client who is unable to swallow. Providing nothing by mouth can lead to nutritional deficiencies, while clear liquids might cause aspiration. Total parenteral nutrition is not necessary if the gastrointestinal tract is functional. Nasogastric feedings are preferred as they can safely provide nutrition without the risks associated with not eating or aspirating.
4. A client is having a seizure; his blood oxygen saturation drops from 92% to 82%. What should the nurse do first?
- A. Open the airway.
- B. Administer oxygen.
- C. Suction the client.
- D. Check for breathing.
Correct answer: A
Rationale: When a client is having a seizure and their blood oxygen saturation drops significantly, the priority action for the nurse is to open the airway. This allows for adequate oxygenation and ventilation. Administering oxygen can come after ensuring the airway is clear. Suctioning the client should be done if there is an airway obstruction, and checking for breathing is part of the assessment but opening the airway takes precedence to ensure proper oxygenation and ventilation during a critical event like a seizure.
5. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:
- A. a vector.
- B. a source, like contaminated water.
- C. food.
- D. the respiratory system.
Correct answer: D
Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.
