Correct Answer: C

Rationale: Autonomic dysreflexia is characterized by a sudden onset of symptoms due to an overactive autonomic nervous system. Hypotension is not indicative of autonomic dysreflexia; instead, hypertension is a hallmark sign. Therefore, hypotension is the correct answer. Flushed face, sudden onset of headache, and nasal congestion are classic symptoms of autonomic dysreflexia caused by a noxious stimulus below the level of the spinal cord injury. These symptoms result from the body's attempt to regulate blood pressure when the normal feedback loop is interrupted.

Correct Answer: A

Rationale: The correct answer is Good Samaritan laws. These laws protect individuals who provide voluntary emergency care from being held liable for any unintended injury or harm that may occur during the care. Good Samaritan laws encourage individuals to assist in emergencies without fear of legal repercussions. HIPAA, on the other hand, focuses on safeguarding patient information and privacy, ensuring confidentiality. The Patient Self-Determination Act (PSDA) pertains to a patient's rights to make decisions about their medical treatment and advance directives. OBRA, enacted in the late 1980s, aims to improve the quality of care in nursing homes and enhance residents' quality of life, focusing on nursing home reform and standards, which is not directly related to immunity for emergency care providers.

Correct Answer: C

Rationale: The document dated 2003 supersedes the previous version and should be used as a basis for care directions. The nurse should follow the 2003 version, place it in the chart, and communicate the update appropriately to ensure that the most current care directions are followed. Choices A and B are incorrect because the 1998 version is now outdated, and the nurse should not rely on it for care decisions. Choice D is incorrect because the nurse should not delay following the updated document, and seeking clarification from the unit manager can lead to avoidable delays in care.

Correct Answer: A

Rationale: In most states, indication of organ donor status is found on the client's driver's license, making it easily accessible for decision-making in critical situations like declaring brain death. Evidence in a last will and testament or a safety deposit box may not be promptly available. Information about organ donation is typically not included on insurance cards. The primary care physician's health record documentation could also be a relevant source for the ICU nurse. Therefore, the correct answer is finding evidence of the client's wishes regarding organ donation on the client's driver's license.

Correct Answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.
