Vocabulary for HESI A2

1. This medication works by inhibiting the action of a certain enzyme. What does inhibiting mean?

A. Blocking
B. Hindering
C. Energizing
D. Blocking improvement

Correct answer: B

Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process. Choices A and D are similar and imply a complete stop of the process rather than just slowing it down. Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.

2. What does oral mean?

A. Through the skin
B. Given through or affecting the mouth
C. Injected
D. Absorbed through digestion

Correct answer: B

Rationale: The correct answer is B: 'Given through or affecting the mouth.' Oral medications are those that are taken by mouth. Choice A is incorrect as 'Through the skin' refers to something being absorbed through the skin, not through the mouth. Choice C, 'Injected,' is incorrect as oral administration does not involve injection but rather ingestion. Choice D, 'Absorbed through digestion,' is partially correct in that oral medications are indeed absorbed through the digestive system, but the term 'oral' specifically refers to the mouth in this context.

A. To expand
B. To draw together
C. To freeze
D. To dissolve

Correct answer: B

Rationale: The correct answer is B: 'To draw together.' Constrict means to narrow or squeeze, making something smaller or tighter. This is the opposite of expanding (choice A), freezing (choice C), and dissolving (choice D), which do not involve the action of drawing together or becoming smaller.

4. Medicine that is given in inhalant form is ___________.

A. dissolved
B. injected
C. taken orally

Correct answer: D

Rationale: Medicine that is given in inhalant form is intended to be breathed in, typically through the mouth or nose. This allows the medication to reach the lungs directly and be absorbed into the bloodstream quickly. Examples of medications given in inhalant form include inhalers used for conditions like asthma and nebulizers for respiratory treatments. Choices A, B, and C are incorrect because medicine in inhalant form is not dissolved, injected, or taken orally; instead, it is inhaled to reach the lungs.
