A nurse in an emergency department receives report from an emergency responder who states a client is being transported following exposure to a 'dirty bomb'. The nurse should prepare to care for a client that has been exposed to which of the following types of agents?

Correct Answer: C

Rationale: The correct answer is C: Radiologic. A 'dirty bomb' combines conventional explosives with radioactive material. Radiologic agents cause damage through exposure to ionizing radiation. The other choices are incorrect because: A: Chemical agents refer to toxic substances, B: Anthrax is a bacterial agent, and D: Sarin is a nerve agent. Thus, the nurse should prepare to care for a client exposed to a radiologic agent due to the nature of a 'dirty bomb' incident.

Correct Answer: A

Rationale: Rationale: Asking the child if the mouth is burning or if there is throat pain is the best tool for the nurse to determine if the child has swallowed a corrosive substance because it directly assesses the immediate symptoms related to ingestion of such substances. Corrosive substances can cause burning sensations in the mouth and throat, indicating potential damage. This question helps the nurse quickly assess the severity of the situation and determine the need for urgent medical intervention. Summary: - Option A is correct as it directly addresses symptoms of corrosive substance ingestion. - Option B is incorrect as it focuses on pulse and breathing, not specific to corrosive substance ingestion. - Option C is irrelevant to assessing corrosive substance ingestion. - Option D is not as direct as Option A in addressing immediate symptoms of corrosive substance ingestion.

Correct Answer: A

Rationale: Step 1: Address the issue directly - "I need to talk to you about unit expectations regarding delegating and completing tasks." Step 2: Establish clear expectations and guidelines for delegation and task completion. Step 3: Provide an opportunity for the staff nurse to understand the concerns and improve behavior. Step 4: Promotes open communication and professional development. Summary: Option A is correct as it addresses the issue constructively, focuses on resolving the conflict through communication and setting clear expectations. Options B, C, and D are incorrect as they involve negative or threatening language, which can escalate the conflict rather than resolve it.

Correct Answer: C

Rationale: The correct answer is C: Reinforce teaching to a client to begin taking enoxaparin at home following a hip arthroplasty. Assigning this task to the LPN is appropriate because it involves medication education, which falls within the scope of practice for an LPN. LPNs are trained to provide patient education and reinforce teaching related to medications. This task does not involve making clinical judgments or assessments beyond the scope of an LPN's practice. Choices A, B, and D are incorrect: A: Completing an admission assessment for a client with COPD requires critical thinking and assessment skills that are typically within the scope of a registered nurse, not an LPN. B: Measuring intake and output for a client with an indwelling urinary catheter involves monitoring for potential complications and assessing the need for interventions, which are responsibilities of a registered nurse. D: Developing a plan of care for a client with cholecystitis also requires critical thinking and assessment skills that exceed

Correct Answer: B

Rationale: The correct answer is B because randomization helps minimize bias by ensuring that participants are assigned to groups randomly, reducing the likelihood of systematic differences between groups. This helps establish a causal relationship between the treatment and outcomes. Choice A is incorrect because randomization does not guarantee a representative sample. Choice C is incorrect as randomization does not determine the sample size. Choice D is incorrect as controlling for variables is typically done through experimental design or statistical methods, not just randomization.
