When applying the Rule of Nines to infants:

Correct Answer: C

Rationale: The Rule of Nines is used to estimate the percentage of body surface area burned. In infants, the head is proportionally larger compared to adults, making it a key area to assess accurately. This is crucial for determining the extent of burns and guiding treatment. Choice C is correct because it highlights the specific anatomical difference in infants. Choices A, B, and D are incorrect as they do not address the unique proportionality of the infant head compared to adults, which is essential in burn assessment for this age group.

Correct Answer: B

Rationale: The correct answer is B because in a patient with altered consciousness after head trauma, CT scanning is crucial to assess for intracranial injuries. It helps identify any hematomas or contusions requiring urgent intervention. Choice A is incorrect as hyperoxia is beneficial in traumatic brain injury. Choice C is not always necessary if the patient maintains airway patency. Choice D is incorrect as a GCS of 10 suggests moderate head injury, not necessarily severe.

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.
