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. A health care provider informs a nurse that the husband of an unconscious client with terminal cancer will not grant permission for a do-not-resuscitate (DNR) order. The health care provider tells the nurse to perform a 'slow code' and let the client 'rest in peace' if she stops breathing. How should the nurse respond?
- A. Telling the health care provider that the client would probably want to die in peace
- B. Telling the health care provider that if the client stops breathing, the health care provider will be called before any other actions are taken
- C. Telling the health care provider that all of the nurses on the unit agree with this plan
- D. Telling the health care provider that 'slow codes' are not acceptable
Correct answer: D
Rationale: The nurse may not violate a family's request regarding the client's treatment plan. A 'slow code' is not acceptable, and the nurse should state this to the health care provider. The definition of a 'slow code' varies among health care facilities and personnel and could be interpreted as not performing resuscitative procedures as quickly as a competent person would. Resuscitative procedures that are performed more slowly than recommended by the American Heart Association are below the standard of care and could therefore serve as the basis for a lawsuit. The other options are inappropriate: Option A is speculative and does not address the issue directly; Option B does not challenge the unethical practice of a 'slow code'; Option C is irrelevant and does not address the ethical concerns raised by the health care provider's request.
3. What should be the first action upon the discovery of an electrical fire?
- A. Disconnect the electrical power if it can be done safely
- B. Smother the source with an object like a blanket
- C. Saturate the source with water or another liquid
- D. Immediately activate the fire alarm
Correct answer: A
Rationale: The correct initial action upon discovering an electrical fire is to disconnect the electrical power if it can be done safely. This helps prevent the fire from spreading through the electrical system. Smothering the fire with a blanket is not recommended for electrical fires as it can fuel the fire. Saturating the source with water or other liquids is also not advised as it can lead to electric shock or spread the fire. Activating the fire alarm is important, but it should be done after disconnecting the power to prevent further escalation of the fire.
4. What is a predisposing factor for cancer of the tongue?
- A. tobacco use
- B. obesity
- C. sun exposure
- D. eating sweets
Correct answer: A
Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.
5. A nurse is performing suctioning through an adult client's tracheostomy tube. The nurse notes that the client's oxygen saturation is 89% and terminates the procedure. Which action would the nurse take next?
- A. Rechecking the pulse oximetry reading
- B. Calling the respiratory therapist
- C. Calling the healthcare provider
- D. Oxygenating the client with 100% oxygen
Correct answer: D
Rationale: The nurse should monitor the client's heart rate and pulse oximetry during suctioning to assess the client's tolerance of the procedure. Oxygen desaturation to below 90% indicates hypoxemia. If hypoxia occurs during suctioning, the nurse must terminate the procedure and oxygenate the client with 100% oxygen to address the hypoxemia promptly and ensure the client's safety. Rechecking the pulse oximetry reading is important, but the priority is to address the hypoxemia by providing oxygen. Contacting the healthcare provider or respiratory therapist is not necessary at this time as the nurse can manage the hypoxemia with oxygenation. Oxygenating the client with 100% oxygen is the immediate action required in this situation.
