Vocabulary HESI A2

1. Select the meaning of the underlined word in the following sentence. Quick action kept the disease from permeating the general population.

A. Conquering
B. Wounding
C. Deterring
D. Infiltrating

Correct answer: D

Rationale: In this context, the word 'permeating' indicates the process of spreading throughout or penetrating into. 'Infiltrating' is the most appropriate synonym for this meaning, as it captures the idea of the disease spreading into the general population. 'Conquering' (Choice A) means to overcome or defeat, which is not the meaning in this context. 'Wounding' (Choice B) means to cause injury, which is not relevant to the sentence. 'Deterring' (Choice C) means to discourage or prevent, which does not fit the context of the disease spreading.

2. Select the meaning of the word 'reflex' in the sentence: 'The typical patellar reflex takes only 50 milliseconds between the initial tap and the leg extension.'

A. Replication
B. Convulsion
C. Reaction
D. Stretching

Correct answer: C

Rationale: In the context of the sentence, the word 'reflex' indicates a quick, automatic response by the body to a stimulus. The patellar reflex, also known as the knee-jerk reflex, involves the leg extending in response to a tap on the patellar tendon. Therefore, the word 'reaction' aligns closely with the nature of the patellar reflex in terms of a rapid and involuntary response. Choices A, B, and D are incorrect: 'Replication' does not capture the concept of a bodily response, 'convulsion' implies a sudden and uncontrollable movement which is not specific to the nature of the patellar reflex, and 'stretching' does not encompass the automatic and rapid nature of a reflex action.

3. Another word for PRECAUTION is?

A. Routine procedure
B. Preventive measure
C. Habit
D. Safeguard

Correct answer: B

Rationale: Another word for PRECAUTION is a preventive measure because both terms refer to actions taken in advance to prevent something untoward from happening. They are proactive steps aimed at avoiding potential risks or harm. While a routine procedure and habit may involve general practices, a preventive measure specifically denotes a proactive step taken to avert potential dangers or issues. 'Routine procedure' is incorrect as it does not necessarily imply preventive action. 'Habit' is incorrect as it refers to repeated behaviors rather than proactive steps. 'Safeguard' is incorrect as it generally means protection rather than a proactive preventive action.

4. The quality, safety, and efficacy of the new medicines are not known. What does efficacy mean?

A. Cost
B. Effectiveness
C. Quality
D. Usage

Correct answer: B

Rationale: Efficacy refers to how effective something is. In this context, it refers to the effectiveness of the new medicines. 'Cost' (Choice A) is incorrect as it relates to the price of something, not its effectiveness. 'Quality' (Choice C) is incorrect as it refers to the standard or degree of excellence. 'Usage' (Choice D) is incorrect as it refers to how something is used, not its effectiveness.

5. A tuberculin skin test should be read within 24 hours of administration.

A. of
B. before
C. after
D. during

Correct answer: A

Rationale: The correct preposition to use after 'within 24 hours' in this context is 'of.' Therefore, the tuberculin skin test should be read within 24 hours of administration. The other choices ('before,' 'after,' 'during') do not correctly convey the relationship between the timing of reading the test and the administration.
