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

Correct Answer: C

Rationale: Rationale: Cerebral edema increases intracranial pressure. Hypercarbia causes cerebral vasodilatation, worsening edema and increasing intracranial pressure. This can lead to further brain damage and neurological deterioration. Therefore, avoiding hypercarbia is crucial in managing cerebral edema. Summary: A: Metabolic acidosis is not directly related to hypercarbia in this context. B: Respiratory acidosis can occur with hypercarbia but is not the primary concern in cerebral edema. D: Neurogenic pulmonary edema is a potential complication of cerebral edema but is not directly caused by hypercarbia.

Correct Answer: C

Rationale: The correct answer is C because hypertension following a head injury may indicate imminent herniation from critically high intracranial pressure. This is a medical emergency as increased blood pressure can lead to further brain damage and potential herniation. Treating the hypertension is crucial to prevent further complications. Choice A is incorrect as treating hypertension in this case is not primarily aimed at reducing intracranial pressure, but rather preventing herniation. Choice B is incorrect as it does not address the acute situation of hypertension post-head injury. Choice D is incorrect as mannitol administration may not always be the first-line treatment for hypertension in this context.

Correct Answer: A

Rationale: The correct answer is A: Keeping all resident information confidential. This is an essential aspect of professional behavior in healthcare to protect the privacy and dignity of residents. Sharing confidential information breaches trust and violates ethical standards. Option B is inappropriate as it can lead to unprofessional conduct and breaches confidentiality. Option C can create favoritism and compromise the nurse's objectivity. Option D blurs professional boundaries and may put the resident in an uncomfortable position. Thus, maintaining confidentiality is crucial for nursing assistants to uphold professionalism and respect residents' rights.

Correct Answer: A

Rationale: The correct answer is A: Abuse. Abuse refers to intentionally causing harm or injury to someone physically, mentally, emotionally, or financially. It covers a wide range of behaviors aimed at exerting power and control over another individual. Assault (B) is the threat or attempt to cause harm, while battery (C) is the actual physical contact resulting in harm. Malpractice (D) refers to professional negligence or misconduct in a specific field, such as medicine or law, and does not encompass the broad scope of harm inflicted on a person as in abuse.

Correct Answer: C

Rationale: The correct answer is C because a nursing assistant's role with a resident's medical chart is to gather information, note observations, and document care provided. This ensures accurate and timely record-keeping for the resident's healthcare team. Choice A is incorrect as keeping the chart without updating or using it is not the assistant's primary responsibility. Choice B is incorrect because making changes to the care plan should be done by licensed healthcare professionals. Choice D is incorrect as suggesting treatment is beyond the scope of a nursing assistant's role.
