Data Interpretation from Texts Flashcards

A public health report states: 'In the first year of the new traffic calming measures, pedestrian injuries in the city center decreased by 30%. However, in the same period, cycling accidents rose by 15%. The adjacent suburban district, which did not implement the new measures, saw a 5% decrease in both pedestrian injuries and cycling accidents.' Which of the following is the most valid conclusion based on this text?

Answer: The traffic calming measures may have had a mixed effect on road user safety in the city center.

The text provides data showing both a significant positive outcome (decreased pedestrian injuries) and a negative outcome (increased cycling accidents) following the implementation of traffic calming measures in the city center. This suggests a mixed or complex impact. The other options are too extreme or make unsupported causal links. Option A is incorrect because of the 30% decrease in pedestrian injuries. Option B is an overstatement, as the changes in the suburb are minor and there could be many other influencing factors. Option D presents a causal link that is not stated or implied in the text.

A medical journal extract reads: 'Patient adherence to Treatment X, a new once-daily medication, was recorded at 85% in our six-month study. This contrasts with the 60% adherence rate typically observed for Treatment Y, the older standard treatment which requires twice-daily administration. A subgroup analysis revealed that in patients over 65, adherence to Treatment X was 92%. The primary reported reason for non-adherence to Treatment Y was forgetfulness.' What can be inferred from this passage?

Answer: Elderly patients find once-daily medication schedules easier to follow.

The text states that adherence to the once-daily Treatment X was significantly higher overall and even higher in the elderly subgroup (92%). It also mentions that the primary reason for missing doses of the twice-daily Treatment Y was forgetfulness. The most logical inference is that the simpler, once-daily schedule of Treatment X is easier for elderly patients to adhere to. The text discusses adherence, not clinical effectiveness (A). It doesn't claim forgetfulness is completely eliminated with Treatment X (C), nor does it make a statement about all patients' preferences (D).

A patient is speaking to a nurse. 'I know the doctor said the procedure is routine, and I've been nodding along, but honestly, my stomach is in knots. Everyone keeps saying 'don't worry,' which somehow makes me worry more. I'm just picturing all the things that could go wrong.' Based on the text, which of the following is the patient most likely feeling?

Answer: Anxiety despite the reassurances given.

The patient explicitly mentions their 'stomach is in knots' and that they are 'picturing all the things that could go wrong,' which are classic descriptions of anxiety. They also state that the reassurances ('don't worry') are paradoxically increasing their worry. While there might be a hint of frustration (B), the core emotion described is anxiety. There is no evidence of anger (A) or confusion about the procedure itself (D); the fear is about potential negative outcomes.

An excerpt from a research summary on sleep patterns states: 'Our study, involving 500 office workers, found a strong negative correlation between hours of screen time after 9 PM and self-reported sleep quality. For every additional hour of late-night screen time, the average sleep quality score decreased by 0.5 points on a 10-point scale. Interestingly, the type of screen (phone, tablet, or laptop) did not significantly alter this outcome. However, participants who engaged in non-screen-related activities, such as reading a physical book, reported stable sleep quality scores.' Which statement is best supported by the text?

Answer: Late-night screen time is negatively associated with sleep quality.

The text explicitly states a 'strong negative correlation' between screen time after 9 PM and sleep quality, and provides specific data to support this. Option C is a direct and accurate summary of this main finding. Option A is an overstatement; the text says reading was associated with 'stable' scores, not necessarily improved ones. Option B is directly contradicted by the text, which says the type of screen did not significantly alter the outcome. Option D is a generalization that is not supported by the information given.

A hospital memo reads: 'To enhance patient recovery, the standard visiting hours of 2 PM to 8 PM will be replaced by a new 'Quiet Time' policy from 1 PM to 4 PM, during which no visitors will be permitted. Family members will be encouraged to visit during the revised hours of 4 PM to 7 PM. This change is based on feedback suggesting that the afternoon is a critical period for patient rest and that interruptions from visitors can be disruptive.' What is the primary purpose of the new policy described in the text?

Answer: To provide patients with a dedicated, uninterrupted rest period.

The memo explicitly states the change is to implement a 'Quiet Time' because feedback suggests the afternoon is a 'critical period for patient rest' and visitor interruptions are 'disruptive.' The main goal is clearly to create a protected time for patients to rest without interruption to 'enhance patient recovery.' While the total visiting hours are reduced, the primary stated goal is not to reduce visitor numbers (A). The memo does not mention staff workdays (C). The new hours (4 PM to 7 PM) may actually be less convenient for some families than the old ones (2 PM to 8 PM), so D is unlikely.

A dialogue between two colleagues, Sarah and Tom, is presented. Sarah says, 'I'm not sure about this new workflow. It seems to add three extra steps to what was a simple process. I'm concerned it will slow down our team's output significantly.' Tom replies, 'I see your point about the extra steps, but the project manager assured us that these checks will reduce the error rate by over 50%, which has been a major issue. Maybe we should give it a try for a week?' Which of the following best describes Tom's response?

Answer: An acknowledgement of the concern, coupled with a counterargument and a proposed solution.

Tom's response is balanced. He starts by validating Sarah's point ('I see your point about the extra steps'), then introduces a counterargument (the benefit of reducing errors, as stated by the project manager), and finishes with a constructive, temporary solution ('Maybe we should give it a try for a week?'). This structure directly matches option B. He does not dismiss her concerns (A), criticize the manager (C), or suggest abandoning the plan (D).
