When applying the Rule of Nines to infants:

Correct Answer: C

Rationale: The Rule of Nines is a method used to estimate the extent of burns on the body. For infants, the head is proportionally larger compared to adults, making up a greater percentage of the total body surface area. Therefore, when applying the Rule of Nines to infants, a larger proportion of the total body surface area is assigned to the head. This is crucial for accurate assessment and treatment of burns in infants. Choice A is incorrect as the Rule of Nines is a standard method for estimating burns. Choice B is incorrect as it is not specific to the Rule of Nines application in infants. Choice D is incorrect as the legs are not proportionally larger in infants compared to adults.

Correct Answer: B

Rationale: The correct answer is B because in a patient with altered consciousness and head trauma, CT scanning is crucial to assess for any intracranial injuries that may require immediate intervention. This helps in guiding further management and determining the severity of the head injury. Option A is incorrect as hyperoxia is actually beneficial in traumatic brain injury. Option C is premature without a proper assessment. Option D is not definitive based solely on the GCS score.

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.
