For the trauma patient with cerebral edema, hypercarbia should be avoided to prevent:

Correct Answer: C

Rationale: Step 1: Cerebral edema causes increased intracranial pressure. Step 2: Hypercarbia leads to cerebral vasodilatation. Step 3: Cerebral vasodilatation increases intracranial pressure further. Step 4: Avoiding hypercarbia helps prevent worsening of cerebral edema. Step 5: Therefore, the correct answer is C: Cerebral vasodilatation should be avoided to prevent further increase in intracranial pressure. Summary: - A: Metabolic acidosis is not directly related to hypercarbia in this context. - B: Hypercarbia can lead to respiratory acidosis but it's not the primary concern in cerebral edema. - D: Neurogenic pulmonary edema is not directly caused by hypercarbia in this scenario.

Correct Answer: C

Rationale: The correct answer is C because hypertension following a head injury may indicate imminent herniation from critically high intracranial pressure. Increased blood pressure can worsen intracranial pressure, leading to herniation and further brain damage. Treating hypertension in this scenario is crucial to prevent worsening intracranial pressure and potential herniation. Choices A, B, and D are incorrect as they do not directly address the urgent concern of impending herniation due to high intracranial pressure. Treating hypertension solely to reduce intracranial pressure (A) or assuming pre-existing hypertension (B) may not address the acute issue. Prompt administration of mannitol (D) may not be appropriate without addressing the underlying cause of hypertension and intracranial pressure elevation.

Correct Answer: A

Rationale: The correct answer is A: Keeping all resident information confidential. Nursing assistants are bound by ethical standards to maintain confidentiality to protect residents' privacy and trust. Sharing resident information violates HIPAA laws and breaches confidentiality. Option B is unprofessional as it can compromise relationships and trust. Option C may create favoritism and bias. Option D blurs professional boundaries and could make residents uncomfortable. Maintaining confidentiality demonstrates professionalism and respect for residents' rights.

Correct Answer: A

Rationale: Rationale: 1. Abuse: Correct because it encompasses all forms of intentional harm. 2. Assault: Involves threats or attempts to harm, not necessarily causing harm. 3. Battery: Involves harmful physical contact, not other forms of harm. 4. Malpractice: Refers to negligence in professional duty, not intentional harm. Summary: Abuse is the most comprehensive term for intentional harm, while assault, battery, and malpractice have specific meanings related to different contexts.

Correct Answer: C

Rationale: The correct answer is C because a nursing assistant is responsible for gathering information, noting observations, and providing care based on the resident's needs. This involves accurately documenting the resident's condition, response to treatment, and any changes in their health status. Keeping the chart for future reference (A) is important, but not the primary responsibility. Making changes to the care plan (B) is typically done by the nurse or healthcare provider. Suggesting treatment options (D) is beyond the scope of a nursing assistant's role.
