The majority of lumbar disc herniations occur at the level of:

Correct Answer: B

Rationale: The majority of lumbar disc herniations occur at the level of L4-L5. This is because the L4-L5 disc segment bears the highest amount of stress and load in the lumbar spine due to its location and mechanics. The intervertebral disc between the fourth (L4) and fifth (L5) lumbar vertebrae is subject to repetitive movements and mechanical stress, making it more susceptible to herniation compared to other levels in the lumbar spine. Additionally, the anatomy of the L4-L5 disc makes it more prone to degeneration and herniation, leading to a higher prevalence of herniated discs at this level.

Correct Answer: B

Rationale: When a client presents with right-sided weakness, it indicates that the underlying issue is likely located in the left hemisphere of the brain. This is due to the contralateral organization of the brain where the right side of the brain controls the left side of the body, and vice versa. Therefore, in Mr. Franco's case, the right-sided weakness suggests the affected lobe is the left lobe of his brain, not the right lobe as stated in option B.

Correct Answer: A

Rationale: Maintaining strict records of intake and output is the best way to assess the client's fluid balance in this situation. Severe burns can lead to fluid loss, which can result in dehydration and other complications. By carefully monitoring the amount of fluid the client is taking in (intake) and the amount of fluid being eliminated from the body (output), healthcare providers can assess the client's fluid balance and make necessary adjustments to prevent dehydration or fluid overload. This approach provides accurate and specific information to guide fluid management and ensure optimal recovery for the client with burns. Monitoring skin turgor, daily weight, and checking for edema are also important measures, but maintaining strict records of intake and output is the most direct and effective method for assessing fluid balance in a client with burns.

Correct Answer: D

Rationale: A brain abscess can be caused by direct invasion of the brain by microorganisms, spread of infection by other organs (such as the heart or lungs), or spread of infection from nearby sites (such as sinuses or the middle ear). In some cases, multiple mechanisms can contribute to the development of a brain abscess. Therefore, the correct answer is that a brain abscess can be caused by all of the above mechanisms.
