A parent calls the hospital hot line and is connected to the triage nurse. The caller proclaims: 'I found my child with odd stuff coming from the mouth and an unmarked bottle nearby.' Which of these comments would be the best tool for the nurse to determine if the child has swallowed a corrosive substance?

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: 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.

Correct Answer: C

Rationale: The correct answer is C: Examine changes over time. In a longitudinal study, researchers follow the same group of participants over an extended period to observe how variables change over time. This allows for the identification of trends, patterns, and developmental trajectories. Choice A is incorrect because a longitudinal study involves collecting data at multiple time points, not just one. Choice B is incorrect as investigating cause-and-effect relationships typically requires experimental designs, not just observational studies like longitudinal studies. Choice D is incorrect because longitudinal studies typically involve tracking specific individuals over time, not randomly selecting participants.

Correct Answer: B

Rationale: The correct answer is B: Discovery phase. During the discovery phase of a lawsuit, both parties gather and exchange evidence and information relevant to the case. A deposition is a key component of the discovery phase where witnesses provide sworn testimony. In this scenario, the nurse manager would likely be asked to provide information related to the case. The other choices are incorrect because: A: Complaint phase - This is when the lawsuit is initiated by the plaintiff filing a complaint. C: Decision phase - There is no specific legal phase known as the decision phase in the typical legal process. D: Trial phase - This phase comes after discovery when the case goes to trial, where the evidence is presented and a decision is made by the court.
