Correct Answer: A

Rationale: The correct answer is A: 'The person, the environment or situation, and health.' In nursing theory, the paradigm includes these core components: the person receiving care, the environment or situation influencing care, and the goal of achieving optimal health outcomes. Choices B, C, and D are incorrect as they do not align with the fundamental aspects of nursing theory and its paradigm.

Correct Answer: C

Rationale: Continuing the same dosage of analgesic is appropriate to manage pain effectively as death nears and the client becomes unresponsive. The primary goal of palliative care in end-of-life situations is to ensure comfort, regardless of the client's level of consciousness. Decreasing the analgesic dosage or discontinuing it could lead to inadequate pain relief, which goes against the principles of palliative care. Prescribing a less potent drug may also compromise pain management in this critical stage. Therefore, maintaining the same analgesic dosage is the most appropriate action to provide comfort and alleviate suffering.

Correct Answer: C

Rationale: The correct answer is C because wound care for a postoperative infection is a skilled service that qualifies for Medicare reimbursement. Choices A, B, and D involve assessments, teaching, and evaluation, which may not meet the criteria for Medicare reimbursement as they do not directly involve a skilled nursing service related to a postoperative condition.

Correct Answer: A

Rationale: The correct information the nurse should provide is that anthrax infection occurs when spores enter a host. Choice B is incorrect as mature anthrax bacteria do not live dormant on inanimate objects. Choice C is incorrect as anthrax spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

Correct Answer: C

Rationale: The correct answer is C: 'Dyspnea and cough.' Pulmonary embolism often presents with a sudden onset of dyspnea (difficulty breathing) and cough, which are due to the obstruction of blood flow in the pulmonary arteries. Choices A, B, and D are incorrect. Positive Homan's sign is associated with deep vein thrombosis, fever and chills are nonspecific symptoms commonly seen in infective endocarditis, and sensory impairment is not typically indicative of pulmonary embolism.
