Mixed Deck — All UCAT Topics Flashcards

In Quantitative Reasoning, which type of data display most commonly presents information that requires extracting multiple values before calculating?

Answer: Data tables with multiple rows and columns

Multi-column data tables require extracting specific values from multiple cells before performing calculations — the most commonly tested and complex QR format.

A chart shows that 40% of hospital admissions are aged 65+. The over-65 population is 18% of the total. What does this suggest?

Answer: Older people are disproportionately represented in hospital admissions

If 18% of the population accounts for 40% of admissions, that group is using hospital services at a rate far above their population share — classic disproportionate representation.

Four friends — A, B, C, D — sit in a row. A must not sit next to D. How many valid arrangements are there?

Answer: 12

Total arrangements = 4! = 24. Arrangements where A sits next to D: treat AD as a block → 3! × 2 = 12. Valid = 24 − 12 = 12.

A blood pressure reading of 120/80 mmHg is recorded. What is the pulse pressure (difference between systolic and diastolic)?

Answer: 40 mmHg

Pulse pressure = systolic − diastolic = 120 − 80 = 40 mmHg.

A train travels at 80 km/h for the first half of a journey and 120 km/h for the second half (equal distances). What is the average speed?

Answer: 96 km/h

Harmonic mean for equal distances: 2×(80×120)/(80+120) = 2×9600/200 = 96 km/h. The arithmetic mean (100) is wrong when speeds cover equal distances.

A student overhears a nurse giving incorrect medication information to a patient. The most appropriate action is:

Answer: Politely interrupt to correct the error — patient safety takes priority — then report to the supervising clinician

Patient safety always takes precedence over hierarchical concerns. A polite, immediate correction followed by reporting to a supervisor is the right course of action.

'Most accidents happen within 5 miles of home.' A driver concludes she is safer driving far from home. What is wrong with this reasoning?

Answer: Most driving also happens near home, so proximity is not the risk factor

The statistic reflects exposure: people drive more near home, so more accidents occur there. Distance from home does not itself increase safety.

A hospital has 3 wards. Ward A has 40 patients, Ward B has 35, Ward C has 25. A random patient is selected. What is the probability they are from Ward B?

Answer: 35/100

Total patients = 100. P(Ward B) = 35/100 = 7/20. Both 35/100 and 7/20 are equivalent; 35/100 is the direct calculation.

An analogy: 3 is to 9 as 4 is to ___?

Answer: 16

3 is squared to get 9 (3² = 9). Applying the same rule: 4² = 16.

A pharmacy label should read 'Amoxicillin 500mg capsules - Take ONE three times daily'. Which of these labels is correct?

Answer: Amoxicillin 500mg capsules - Take ONE three times daily

Only option A matches exactly. Option B misspells 'Amoxicillin' (missing an 'l'), option C misspells 'daily' as 'dialy', and option D has the wrong dose (5000mg instead of 500mg).

A logic puzzle: If A is true, B is false. If B is false, C is true. A is true. What is C?

Answer: True

A is true → B is false → C is true. The chain of conditionals resolves fully.

At which test centre provider are UCAT exams administered?

Answer: Pearson VUE

UCAT exams are delivered at Pearson VUE test centres across the UK and internationally.

A medical student is offered payment by a patient to 'bump them up the waiting list'. The most appropriate response is:

Answer: Decline the offer, explain that treatment is allocated on clinical need, and report the offer

Accepting payment for preferential access is corrupt and illegal. Even declining without reporting fails to protect the integrity of the system. The offer must be reported.

A hospital reduces average length of stay from 6 days to 4.5 days. By what percentage was it reduced?

Answer: 25%

Reduction = 1.5 days. Percentage = (1.5/6) × 100 = 25%.

A candidate reads that their UCAT score is at the 80th percentile. This means:

Answer: They scored higher than 80% of that year's UCAT cohort

Percentile rank means performing better than that percentage of the comparison group. 80th percentile = performed better than 80% of the cohort.

A confidence interval for a treatment effect is 1.2 to 3.8 (relative risk). What does this indicate?

Answer: The treatment significantly increases risk — the interval excludes 1

A CI for relative risk that excludes 1.0 indicates statistical significance. Since both bounds are above 1, the treatment is associated with increased risk.

A bag contains 3 red, 4 blue, and 5 green balls. If one ball is drawn at random, what is the probability it is NOT green?

Answer: 7/12

Total balls = 12. Non-green = 3 + 4 = 7. Probability = 7/12.

A colleague confides they have been self-medicating with prescription drugs. What should you do first?

Answer: Encourage them to seek appropriate help and support, such as occupational health

The first step is to encourage the colleague to seek appropriate professional help, which addresses both their health needs and potential patient safety concerns.

'Either we invest in renewable energy or we face severe climate consequences.' This argument structure is an example of:

Answer: False dilemma

Presenting only two options when more may exist is a false dilemma (false dichotomy). Other energy or policy options might also avert climate consequences.

A car depreciates by 20% per year. It costs £25,000 new. What is it worth after 2 years?

Answer: £16,000

After year 1: £25,000 × 0.8 = £20,000. After year 2: £20,000 × 0.8 = £16,000. Compound depreciation, not simple.
