ATDH - Admission Test for Dental Hygiene Language and Grammar Rules Questions and Answers

Question 1

Read the following sentence: 'Each of the dental hygiene students are required to bring their own set of instruments.' Which of the following revisions corrects the grammatical error in the sentence?

Accepted Answer

Each of the dental hygiene students is required to bring his or her own set of instruments.

Answer

The subject of the sentence is 'Each,' which is singular. Therefore, the verb must also be singular ('is required'). Additionally, the pronoun must agree with the singular subject; 'his or her' is the grammatically correct singular pronoun to use in this formal context. 'Their' is a plural pronoun.

Question 2

A dental hygienist is writing a patient education brochure and wants to ensure the tone is professional and clear. Which of the following sentences is most appropriate for this purpose?

Accepted Answer

Consistent daily brushing and flossing are essential for preventing periodontal disease and tooth decay.

Answer

This sentence uses formal language ('consistent,' 'essential,' 'preventing periodontal disease'), maintains an objective and professional tone, and clearly communicates the necessary information without using slang or overly casual phrasing. The other options are too informal or subjective for a professional document.

Question 3

Which of the following sentences contains a punctuation error?

Accepted Answer

After sterilizing the instruments the hygienist prepared the treatment room.

Answer

The sentence 'After sterilizing the instruments the hygienist prepared the treatment room' has an introductory adverbial phrase ('After sterilizing the instruments'). According to standard punctuation rules, such introductory phrases should be set off from the main clause with a comma. The correct punctuation is: 'After sterilizing the instruments, the hygienist prepared the treatment room.'

Question 4

Identify the sentence that is grammatically correct and uses parallel structure.

Accepted Answer

Proper oral hygiene involves brushing thoroughly, flossing daily, and rinsing with an antiseptic mouthwash.

Answer

This sentence correctly uses parallel structure by listing three gerund phrases ('brushing thoroughly,' 'flossing daily,' 'rinsing with an antiseptic mouthwash'). The other options mix different grammatical forms (gerunds, infinitives, and nouns) within their lists, violating the rule of parallelism.

Question 5

Choose the word that correctly completes the following sentence: 'The dental hygienist gave the patient expert _______ on how to improve their brushing technique.'

Accepted Answer

advice

Answer

'Advice' is a noun meaning 'guidance or recommendations.' 'Advise' is a verb meaning 'to offer suggestions.' In this sentence, the hygienist is giving something (a noun) to the patient. Therefore, 'advice' is the correct choice.
