Correct Answer: A

Rationale: Step 1: Level of consciousness is the most reliable index of cerebral state because it directly reflects the functioning of the brain. Changes in consciousness can indicate alterations in cerebral perfusion and potential increases in intracranial pressure. Step 2: Unilateral papillary dilatation may suggest an increase in intracranial pressure, but it is not as reliable as level of consciousness in assessing overall cerebral state. Step 3: Increased systolic blood pressure can occur due to various reasons and may not specifically indicate changes in intracranial pressure. Step 4: Decreased pulse pressure may be related to factors such as hypovolemia or cardiac conditions, but it is not a direct indicator of cerebral state or intracranial pressure.

Correct Answer: D

Rationale: The correct answer is D: Reduce airway inflammation. Corticosteroids like methylprednisolone are used in emphysema to reduce inflammation in the airways, which can help improve lung function and symptoms. Corticosteroids work by suppressing the immune response that leads to inflammation in the airways. This can help decrease swelling, mucus production, and constriction of the airways, all of which contribute to the symptoms of emphysema. Dry secretions (choice A) and improving oxygen-carrying capacity (choice B) are not the primary purposes of corticosteroid treatment in emphysema. Treating infection that causes a low level of hemoglobin (choice C) is not relevant to corticosteroid treatment for emphysema.

Correct Answer: D

Rationale: The correct answer is D: To establish a database to identify problems and strengths. This initial assessment is crucial for gathering comprehensive information about the client's health status, including past medical history, current health problems, and potential risk factors. By establishing a database, the nurse can identify both existing health issues that need to be addressed and strengths that can be built upon for effective care planning. This assessment serves as the foundation for developing an individualized care plan and monitoring the client's progress throughout their hospital stay. Explanation of other options: A: To gather data about a specific and current health problem - While this may be part of the assessment process, the main purpose is broader in scope to establish a comprehensive database. B: To identify life-threatening problems that require immediate attention - While identifying urgent issues is important, the initial assessment is not solely focused on life-threatening problems. C: To compare and contrast current health status to baseline data - While comparing to baseline data is important for tracking changes, the primary purpose

Correct Answer: C

Rationale: The correct answer is C: Introduce variations in styles of clothing. This suggestion promotes the client's self-image by helping her feel more comfortable and confident in her appearance despite the lymphedema. It allows her to express her personal style while accommodating the enlarged arm. A: Placing the arm in a sling does not address the client's self-image concerns and may further highlight the abnormality. B: Applying cold soaks may help with swelling but does not directly address the client's self-image. D: Tying a tight bandage can worsen lymphedema and does not address the client's self-image concerns.

Correct Answer: C

Rationale: Upon arrival, checking the lungs for equal breath sounds bilaterally is the first action. This is crucial to assess airway patency and breathing effectiveness in a patient with a history of diving accident and intubation. Ensuring proper oxygenation takes precedence over other actions. Taking vital signs, inserting an IV line, and performing a neurologic check can wait until airway and breathing are adequately assessed.
