Vocabulary for HESI A2

1. What does Redundancy mean?

Correct answer: B

Rationale: Redundancy means having more than is needed, making 'Surplus' the correct choice. The term does not relate to 'Deficiency' (lack), 'Delicate' (fragile), or 'Abundance' (plenty). In the context of this question, Redundancy refers to an excess or surplus of something.

2. How many cakes do you need for a class of 70 students and 3 staff members if each cake provides 24 servings?

Correct answer: A

Rationale: To determine the number of cakes needed, calculate the total number of people, which is 70 students + 3 staff = 73 people. Since each cake serves 24 people, divide the total number of people by 24 to get approximately 3.04. You cannot have a fraction of a cake, so round up to the next whole number, which is 4. Therefore, you need 4 cakes to serve the class of 70 students and 3 staff members. Choice B (2) is incorrect because 2 cakes would not be enough to serve 73 people. Choice C (5) is incorrect as it would be an excess of cakes. Choice D (3) is incorrect because 3 cakes would not be sufficient to serve 73 people.

3. Which word is not used correctly in the context of the following sentence: 'There is no real distinction between the two treatment protocols recommended online.'

Correct answer: B

Rationale: The correct word that should replace 'among' in the sentence is 'between' when referring to a distinction between two things. 'Among' is used when referring to more than two items or when the items are part of a group. In this context, 'between' is more appropriate as there are only two treatment protocols being compared.

4. Select the word in the following sentence that is not used correctly. Collecting personal and vital data is one of the roles of an intake nurse.

Correct answer: C

Rationale: The word 'datum' is singular, and the correct plural form of 'datum' is 'data.' Therefore, the sentence should use 'data' instead of 'datum' to be grammatically correct. In the sentence provided, 'datum' should be replaced with 'data' to maintain proper grammar and syntax. Choices A, B, and D are used correctly in the sentence, so they are not the correct answer.

5. Which term is descriptive of a small child just learning to walk?

Correct answer: B

Rationale: The correct answer is 'B: Toddler.' A toddler is a young child typically between the ages of one and three who is just learning to walk. 'Obese' (choice A) refers to excess body fat, 'Geriatric' (choice C) pertains to elderly individuals, and 'Hale' (choice D) means strong and healthy, none of which are descriptive of a small child learning to walk.
