What is the first aid for frostbite?

Correct Answer: A

Rationale: First aid for frostbite involves running cold water over the affected area. It is important to avoid warm or hot water as it can shock the area and cause further tissue damage. Warm water should not be used to rapidly rewarm the affected area. Similarly, hot water should also be avoided as it can warm the area too quickly and potentially cause harm. Covering the area with a blanket and using a heating pad may not be effective and can even lead to more damage. Seeking medical assistance is crucial if the tissue appears necrotic to prevent further complications.

Correct Answer: C

Rationale: The most appropriate action to reduce the risk of infection during the post-operative period is to remove the urinary catheter as soon as the client is ambulatory. Urinary catheters can serve as a source of bacteria, increasing the risk of infection in the bladder or urethra. By removing the catheter promptly once the client is mobile, the risk of infection can be minimized. Option A, flushing the central line with heparin, is not directly related to reducing urinary tract infections. Option B, administering narcotic analgesics as needed, is important for pain management but does not directly address infection prevention. Option D, ordering a high-protein diet, may be beneficial for wound healing but does not specifically target infection risk reduction in the post-operative period.

Correct Answer: B

Rationale: The correct answer is 'Nausea, vomiting, seizures.' Carbon monoxide poisoning can present with symptoms such as headache, dizziness, weakness, nausea, vomiting, and confusion. Severe cases can progress to seizures, coma, and even death. It is crucial for healthcare providers to recognize these symptoms promptly to initiate appropriate treatment. Choices A, C, and D are incorrect because a red rash, flushing of the face and neck, and abdominal pain radiating to the back are not typically associated with carbon monoxide poisoning. It is essential to be aware of the common manifestations of carbon monoxide poisoning to ensure timely intervention and prevent adverse outcomes.

Correct Answer: C

Rationale: The five rights of medication administration are essential to ensure safe and effective drug delivery to clients. The correct answer includes ensuring the right client receives the right drug at the right dose, via the right route, and at the right time. These elements are crucial to prevent medication errors and ensure optimal therapeutic outcomes. Choice A is incorrect as it includes 'right nurse' which is not part of the five rights of medication administration. Choice B is incorrect as it includes 'right order' which is not part of the five rights. Choice C is incorrect as it includes 'right drug' and 'right route', but it lacks 'right client' and 'right time'. Choice D is incorrect as it includes 'right physician' which is not part of the five rights.

Correct Answer: C

Rationale: When a fire starts in a healthcare setting, the first action of the nurse is to move clients and anyone who may be in danger to a safe location. Ensuring the safety of clients is the top priority during emergencies. While using a fire extinguisher could be a subsequent step to contain the fire, the immediate focus should be on evacuating individuals from harm's way. Calling 9-1-1 is important, but moving clients to safety should be the nurse's initial response. Throwing water on the fire may not be effective or safe, as it can exacerbate some types of fires.

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: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

Correct Answer: A

Rationale: When using a cold pack for therapeutic purposes, it is essential to monitor the site to prevent tissue damage. Prolonged use of cold therapy can lead to pale, mottled skin with a bluish appearance. This change in skin color indicates poor circulation, and the cold pack should be removed immediately to prevent tissue injury. Choices B, C, and D are incorrect because the duration of cold pack application, client complaints of nausea, and capillary refill time do not specifically indicate the need for the cold pack to be removed due to potential tissue damage.

Correct Answer: D

Rationale: Culture has four basic characteristics, one of which is that it is adapted to specific conditions related to environmental and technical factors and to the availability of natural resources. The other three characteristics are: (1) learned from birth through the processes of language acquisition and socialization; (2) shared by all members of the cultural group; and (3) dynamic and ever-changing. Culture is not static and unchanging but is dynamic and ever-changing. Members of a culture do not necessarily share similar physical characteristics; that refers to race. Similarly, members of a culture do not necessarily share a common geographic origin and religion; that refers to ethnicity.
