English Language Usage, Grammar, Punctuation, and Style
The English Language Usage, Grammar, Punctuation, and Style domain tests whether you can produce clear, consistent, professional medical prose. Items target sentence boundaries, agreement, modification, punctuation, homophones, and house style.
Core rules
- Sentence completeness: every sentence needs a subject and a finite verb. Repair fragments and comma splices. “The patient was seen in the emergency room, he complained of chest pain” is a comma splice; use a period, semicolon, or conjunction.
- Agreement: match subject and verb, and pronoun and antecedent. Collective nouns such as team usually take a singular verb in U.S. medical style; data is often plural in formal writing, but follow the facility style guide.
- Modification: place a modifier next to what it modifies. “Complaining of chest pain, the ECG was ordered” dangles because the ECG cannot complain. Rewrite: “Because the patient was complaining of chest pain, an ECG was ordered.”
- Tense and voice: history and physical notes typically use past tense for history and present tense for current findings. Prefer active voice when it improves clarity, but passive voice is acceptable when the actor is unknown or unimportant.
- Punctuation: use commas for introductory elements, items in a series, and nonrestrictive clauses; use semicolons between closely related independent clauses; use colons to introduce a list or explanation; hyphenate compound modifiers before a noun (45-year-old woman, well-differentiated tumor) but not after (the woman is 45 years old).
- Homophones: ileum/ilium, perineal/peroneal, affect/effect, principal/principle, dysphagia/dysphasia.
Worked example
Original: “Patient is a 45 year old female with a history of diabetes complaining of chest pain, she denies shortness of breath.” Problems: missing hyphens in the compound modifier, a dangling modifier (complaining attaches to diabetes), and a comma splice. Revised: “The patient is a 45-year-old woman with a history of diabetes who complains of chest pain; she denies shortness of breath.” The revision supplies the relative pronoun, uses a semicolon, and hyphenates the age phrase.
Traps
Watch for comma splices disguised by long clauses, dangling participles at the start of sentences, and inconsistent tense within one paragraph. Do not hyphenate after the noun, overcapitalize generic terms, or insert an apostrophe into a nonpossessive plural. Avoid “patient denies” for objective findings the patient cannot deny, such as fever.
