HESI A2 Vocabulary 2023

Correct Answer: D

Rationale: The correct answer is D: weight at birth. LBW stands for Low Birth Weight, which is a crucial indicator of an infant's health and development. Monitoring a baby's weight at birth is essential for assessing growth and identifying potential health issues. The other choices are incorrect because A (genetic makeup) is not typically abbreviated as LBW, B (feeding schedule) is unrelated to birth weight, and C (Babinski response) is a neurological reflex test, not related to weight at birth.

Correct Answer: A

Rationale: The correct answer is A: syringe. To aspirate fluid means to draw it into a syringe for further use or analysis. Syringes are designed for precise measurement and extraction of fluids. Beakers and test tubes are used for holding and mixing fluids, not for aspiration. Flange is a mechanical component and not used for aspiration of fluids.

Correct Answer: C

Rationale: The correct answer is C: nostrum. A remedy is a substance or treatment that cures ailments. "Nostrum" is a synonym for remedy or cure, making it the most appropriate choice. A: inoculation refers to the process of introducing a vaccine to prevent disease. B: indicator is something that provides information or points out a condition, not necessarily a cure. D: serum is a component of blood and not specifically related to curing ailments. Therefore, C is the correct answer because it directly relates to the concept of a remedy curing ailments.

Correct Answer: D

Rationale: The correct answer is D, "To move side to side." In the context of the sentence, 'yaw' refers to a horizontal movement of the robotic arm requiring adjustment. This movement aligns with the definition of yaw as a side-to-side motion, commonly used in aviation and robotics. Choice A, "To gape open," is incorrect as it does not fit the context of the sentence. Choice B, "To move up and down," does not align with the horizontal movement described. Choice C, "To close tightly," is also incorrect as it does not relate to any form of movement but rather a stationary action.

Correct Answer: B

Rationale: The correct answer is B: Drooping or loose. Flaccid means lacking firmness or stiffness, often used to describe something that is limp or lacking in strength or vigor. In this context, flaccid refers to something that is drooping or loose. Choice A is incorrect as light-colored does not relate to the definition of flaccid. Choice C is incorrect as uncontaminated is not a synonym of flaccid. Choice D is incorrect as unusually aggressive is unrelated to the meaning of flaccid.
