Worked examples: how to reason through PLAB 1 questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What does 'best interests' decision-making require under the MCA 2005 when a patient lacks capacity?

1. Following the patient's family's wishes
2. Considering all relevant factors including the patient's past wishes, values, and beliefs; consulting those close to them; and choosing the least restrictive option that meets their needs
3. Making the medically optimal decision regardless of personal values
4. Applying for a court order before any decision

Answer: B. Considering all relevant factors including the patient's past wishes, values, and beliefs; consulting those close to them; and choosing the least restrictive option that meets their needs

Explanation:

Option B is right because best interests under the MCA 2005 is a structured, patient-centred process. You weigh every relevant factor, including the patient's past and present wishes, values and beliefs, you consult family, carers or an advocate, and you choose the least restrictive option that still meets their needs.

Option A is wrong because relatives are consulted but do not decide. Option C is wrong because a medically optimal answer that ignores the person's values is not a best interests decision; the concept is broader than clinical benefit. Option D is wrong because a court order is not needed before every decision, only in particular difficult cases.

Rule to remember: capacity is decision-specific, and when it is lacking you decide with the person's own perspective at the centre, not with your own preference or the family's.

Example 2

Question: A patient on simvastatin 40 mg reports new-onset muscle pain and weakness. Blood tests show a creatine kinase (CK) level 10 times the upper limit of normal. What is the most appropriate action?

1. Continue simvastatin and reassure the patient
2. Stop simvastatin immediately — the elevated CK indicates rhabdomyolysis/myopathy, a serious adverse effect of statins
3. Increase the dose of simvastatin
4. Add a fibrate to the simvastatin

Answer: B. Stop simvastatin immediately — the elevated CK indicates rhabdomyolysis/myopathy, a serious adverse effect of statins

Explanation:

Option B is right. New muscle pain and weakness with a creatine kinase level 10 times the upper limit of normal on simvastatin 40 mg suggests statin myopathy, which can progress to rhabdomyolysis and acute kidney injury. The statin should be stopped straight away.

Option A is wrong because reassurance and continuing the drug risks serious muscle and kidney damage. Option C is wrong because a higher dose would worsen the toxicity. Option D is wrong because adding a fibrate to a statin increases the risk of myopathy further.

Rule to remember: symptoms plus a markedly raised CK on a statin mean stop the drug. Once CK has normalised, a different statin at a low dose, or another lipid-lowering agent, can be considered cautiously.

Example 3

Question: A patient is prescribed amoxicillin for a chest infection. They mention they are also taking the combined oral contraceptive pill. According to current BNF guidance, does amoxicillin interact with the combined oral contraceptive?

1. Yes — all antibiotics reduce the efficacy of the pill and additional contraception is always needed
2. No — non-enzyme-inducing antibiotics like amoxicillin do not reduce the efficacy of the combined oral contraceptive according to current evidence and BNF guidance
3. Yes — amoxicillin specifically destroys oestrogen in the gut
4. Antibiotics only interact with the progesterone-only pill

Answer: B. No — non-enzyme-inducing antibiotics like amoxicillin do not reduce the efficacy of the combined oral contraceptive according to current evidence and BNF guidance

Explanation:

Option B is right. Current BNF and FSRH guidance says that non-enzyme-inducing antibiotics such as amoxicillin do not reduce the efficacy of the combined oral contraceptive. Extra precautions are needed with enzyme-inducing drugs such as rifampicin, carbamazepine and phenytoin.

Option A is wrong because it treats all antibiotics as the same, which is an outdated belief. Option C is wrong because amoxicillin does not destroy oestrogen in the gut. Option D is wrong because the question is not limited to the progesterone-only pill, and the key distinction is whether a drug induces liver enzymes.

Rule to remember: ask whether the drug induces enzymes, not whether it is an antibiotic. Severe vomiting or diarrhoea is a separate issue that can affect absorption.

How to use these practice tests

Start with the GMC's own pages on the PLAB 1 format and results so you know what the exam asks of you. Then take the free PLAB 1 practice test as a baseline, without notes and under timed conditions, and note which topics cost you the most marks.

Next, work through the topic sets, spending most time on your weakest areas. Useful starting points are clinical medicine, pharmacology and therapeutics, medical ethics and consent and UK clinical guidelines and prescribing safety. Add NHS protocols if UK practice is new to you.

After each set, read every explanation, including those for questions you got right, and write down the rule behind each mistake. Check anything you are unsure of against current UK guidance such as the BNF, not against memory.

Close to test day, do full-length timed runs of 180 questions in 3 hours so that pacing feels familiar. Our questions are written by us and are not real exam questions, so use them to build reasoning, not to predict the paper.

Sample PLAB 1 Practice Questions

Try these questions from our free PLAB 1 practice tests. The correct answer and an explanation follow each question.

1. A 25-year-old woman has TFTs showing: TSH <0.01 mIU/L, free T4 35 pmol/L, free T3 12 pmol/L. What do these results indicate?

   • A. Primary hypothyroidism
   • B. Hyperthyroidism (primary)
   • C. Secondary hypothyroidism
   • D. Sick euthyroid syndrome

Answer: B. Hyperthyroidism (primary)

A suppressed TSH (<0.1) with elevated free T4 and T3 indicates primary hyperthyroidism. The high thyroid hormones are suppressing TSH via negative feedback on the pituitary. In secondary hypothyroidism (pituitary failure), TSH is low but T4 is also low.

Answer: B. Knowledge, skills, and performance; safety and quality; communication, partnership, and teamwork; maintaining trust

GMC Good Medical Practice is organised around four domains: (1) Knowledge, skills, and performance; (2) Safety and quality; (3) Communication, partnership, and teamwork; (4) Maintaining trust. All registered doctors must meet the standards in all four domains.

Answer: B. The proportion of disease-free individuals who test negative (true negative rate) — a specific test rarely gives false positives

Specificity = True Negatives / (True Negatives + False Positives). A highly specific test rarely gives a positive result in people without disease. Mnemonic: SpPin — a Specific test, when Positive, rules IN disease. Useful for confirmatory tests.

Answer: B. The proportion of people with the disease who test positive (true positive rate) — a sensitive test rarely misses disease

Sensitivity = True Positives / (True Positives + False Negatives). A highly sensitive test has a low false-negative rate — it rarely misses cases of the disease. Mnemonic: SnNout — a Sensitive test, when Negative, rules OUT disease. Useful for screening tests.
