Correct Answer: D

Rationale: The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.

Correct Answer: C

Rationale: Bioterrorism is the act of using harmful agents like bacteria or viruses with the intention to harm others. In the context of healthcare, nurses may be involved in disaster response if bioterrorism weapons affect the community. Choice A, assimilation, refers to the process of absorbing and integrating information or ideas. Choice B, defense intervention, does not specifically relate to the intentional use of microorganisms to harm others. Choice D, environmental remediation, involves the process of cleaning up pollution or contamination in the environment, which is unrelated to the deliberate use of pathogens for harmful purposes.

Correct Answer: A

Rationale: Pain, cool skin, and edema at an IV injection site indicate IV infiltration. The reddened and cool skin around the IV site, along with localized pain and a slowed IV drip rate, are classic signs of infiltration. Infiltration occurs when IV fluids or medications enter the surrounding tissues instead of the vein, leading to potential tissue damage. Phlebitis is inflammation of a vein, not infiltration. A blood clot in the distal arteries of the wrist would not cause these specific symptoms. Myocardial ischemia and heart attack are unrelated to the client's localized hand pain and IV issues.

Correct Answer: D

Rationale: The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.

Correct Answer: A

Rationale: The correct answer is when the client suddenly complains of back pain and has chills. Signs of a transfusion reaction include back pain, chills, dizziness, increased temperature, and blood in the urine. These signs indicate a possible adverse reaction to the blood transfusion. Dependent edema in the extremities is not typically associated with a transfusion reaction. A seizure is not a common sign of a transfusion reaction unless it is due to severe complications. A decrease in heart rate to 60 bpm is not a typical sign of a transfusion reaction, but rather bradycardia may indicate other underlying conditions or medications.
