Vocabulary for HESI A2

1. What does exogenous mean?

A. Produced within the body
B. Produced outside the body
C. A byproduct
D. Caused by bacteria

Correct answer: B

Rationale: Exogenous means produced outside the body. In this context, 'within the body' (Choice A), 'a byproduct' (Choice C), and 'caused by bacteria' (Choice D) do not accurately define exogenous. The correct definition of exogenous specifically refers to something originating or produced externally.

2. Which word names a medicine whose purpose is to induce vomiting?

A. Laxative
B. Emetic
C. Vaccine
D. Analgesic

Correct answer: B

Rationale: The correct answer is B, 'Emetic.' An emetic is a medication specifically designed to induce vomiting. This helps the body expel toxic substances or clear the stomach. Choice A, 'Laxative,' aids in relieving constipation by promoting bowel movements, not inducing vomiting. Choice C, 'Vaccine,' is a substance used to stimulate the immune system against specific diseases, not to induce vomiting. Choice D, 'Analgesic,' refers to a medication used to relieve pain, not to induce vomiting. Therefore, options A, C, and D are incorrect in the context of inducing vomiting.

3. Which word is NOT CORRECT? The student did not recognize which backpack was hers.

A. Backpack
B. Student
C. Hers
D. Recognize

Correct answer: C

Rationale: The correct answer is 'C: Hers.' The possessive pronoun 'hers' does not require an apostrophe. The use of 'her's' with an apostrophe is grammatically incorrect. Choices A, B, and D ('Backpack,' 'Student,' and 'Recognize') are all spelled correctly and are grammatically sound in the sentence provided.

4. A patient who is lethargic may seem _______

A. Energetic
B. Exhausted
C. Restless

Correct answer: B

Rationale: The correct answer is B: 'Exhausted.' Lethargic describes a state of feeling sluggish or lacking energy, which aligns with being exhausted. Choice A, 'Energetic,' is the opposite of lethargic. Choice C, 'Restless,' implies a different state of agitation than lethargy. Choice D, 'Hyperactive,' describes excessive activity, which contrasts with the lethargic state.

5. A UTI is likely to involve the ___________.

A. bones
B. throat
C. stomach
D. bladder

Correct answer: D

Rationale: A UTI (Urinary Tract Infection) is likely to involve the bladder. A urinary tract infection is an infection in any part of the urinary system, which includes the kidneys, ureters, bladder, and urethra. The most common type of UTI is a bladder infection where bacteria enter the bladder and cause inflammation and infection. Choices A, B, and C are incorrect because a UTI specifically affects the urinary tract system and not the bones, throat, or stomach.
