1. Choose the meaning of the word 'exposure' in the following sentence: 'People with weakened immune systems should avoid exposure to flu.'

A. Disclosure
B. Pretense
C. Contact
D. Display

Correct answer: C

Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.

2. What does the term 'residual' refer to in the following sentence? The nurse was asked to record the residual urine in the patient's bladder.

A. Measurement
B. What is left
C. Total volume
D. Color and clarity

Correct answer: B

Rationale: The term 'residual' refers to what is left after the main part has been taken or used. In this context, 'residual urine' specifically means the urine that remains in the bladder after urination. Choices A, C, and D do not accurately capture the meaning of 'residual' in this sentence. 'Measurement' (A) is too general, 'Total volume' (C) does not specifically pertain to what remains, and 'Color and clarity' (D) is unrelated to the concept of what is left.

3. In the address 'Mr. Ryan, 1600 Pennsylvania Ave., Washington, DC 20003,' which word is the salutation?

A. 1600 Pennsylvania Ave.
B. 20003 (Area code)
C. Ryan
D. Mr.

Correct answer: D

Rationale: The correct answer is 'D - Mr.' The salutation is the formal title used before a person's name, which in this case is 'Mr.' Other choices are incorrect as '1600 Pennsylvania Ave.' is the street address, '20003' is the zip code, and 'Ryan' is the recipient's name.

4. What does instigate mean?

A. Deactivate
B. Activate
C. Suppress
D. Evaluate

Correct answer: B

Rationale: The correct answer is B: 'Activate.' Instigate means to initiate or provoke a particular event or action. Choice A, 'Deactivate,' is incorrect as it means to make something inactive, which is the opposite of instigate. Choice C, 'Suppress,' is incorrect as it means to restrain or prevent something, not to initiate it. Choice D, 'Evaluate,' is incorrect as it means to assess or judge the value or quality of something, not to start or provoke it.

Rationale: The breastbone is called the sternum. It is a flat bone located in the center of the chest that connects the ribs together and protects the heart and lungs. The term 'stelic' (choice A), 'steres' (choice B), and 'sterol' (choice C) are not correct terminologies for the breastbone.
