Correct Answer: B

Rationale: A nursing advocate does not make decisions for others but instead empowers individuals to make decisions for themselves. By encouraging individuals to make their own decisions and supporting them in this process, nursing advocates uphold the principle of self-determination. This approach respects the autonomy and independence of individuals in managing their care. Therefore, the correct answer is to 'encourage persons to make decisions for themselves and act with or on behalf of the person to support those decisions.' Choices A, C, and D are incorrect as they do not align with the role of a nursing advocate in promoting patient autonomy and self-determination.

Correct Answer: D

Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.

Correct Answer: D

Rationale: Acyclovir is an antiviral medication specifically effective in treating herpes infections. It works by inhibiting the replication of the herpes virus, shortening the duration of the infection. While Acyclovir can be used in HIV and AIDS patients to treat opportunistic viral infections, it is not a primary drug for managing HIV or AIDS itself. Candida is a type of fungus, and infections caused by Candida are treated with antifungal medications, not antivirals like Acyclovir. Therefore, the correct answer is herpes.

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: D

Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1°F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
