Correct Answer: D

Rationale: Hazards of improper splinting can lead to the aggravation of a bone or joint injury, reduced distal circulation, and delay in transporting a client with a life-threatening injury. Choosing 'All of the above' (Option D) is the correct answer as it encompasses all the hazards mentioned. Option A is incorrect because it only addresses one aspect of the hazards. Option B is incorrect as it does not cover all the hazards associated with improper splinting. Option C is incorrect as it focuses on only one hazard and does not account for the others.

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: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

Correct Answer: D

Rationale: Amylase is elevated in conditions of pancreatic inflammation, such as pancreatitis. Pancreatitis is characterized by the inflammation of the pancreas, leading to the leakage of amylase into the bloodstream. Elevated levels of amylase are a key diagnostic marker for pancreatitis. Alkaline phosphatase is associated with liver and bone conditions, not pancreatitis. Acid phosphatase is more related to prostate health and is not specific to pancreatitis. Creatine phosphokinase is found in tissues like muscle and brain, and elevated levels are seen in conditions like muscle injury or heart attack, not pancreatitis.

Correct Answer: D

Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.
