Correct Answer: A

Rationale: Brown-Séquard 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.

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.

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.

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.

Correct Answer: D

Rationale: The correct answer is '
To be aware of the role of the licensed nurse.' Nurse practice acts outline the scope of practice for nurses, defining what constitutes nursing practice and the role of licensed nurses.
Choice A is incorrect because hospital and long-term care facility policies are institution-specific and not typically covered in the nurse practice act.
Choice B is incorrect as the scope of practice for nurses is a part of the nurse practice act, but it's not the sole purpose for a nurse to refer to it.
Choice C is incorrect as health care policies in a state are governed by other legislative acts, not the nurse practice act.
