HESI A2 Vocabulary 2023

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: D

Rationale: The correct answer is D: dizzy. Vertigo is a sensation of spinning or dizziness. Patients experiencing vertigo feel as if they or their surroundings are moving when they are not. Therefore, a vertiginous patient would be dizzy. Choices A, B, and C are incorrect because being on a liquid diet, lying flat, or being burned do not directly relate to vertigo or the symptoms associated with it.

Correct Answer: B

Rationale: The correct answer is B: Water that is lukewarm. Tepid bathwater refers to water that is neither too hot nor too cold, but rather at a moderate or lukewarm temperature. This is the ideal temperature for bathing as it is comfortable and soothing. Choice A is incorrect because tepid water is not salty. Choice C is incorrect because tepid water is not icy; it is warmer than cold water. Choice D is incorrect because tepid water refers to the temperature of the water, not the quantity.

Correct Answer: A

Rationale: The correct answer is A: A test of brain activity. EEG stands for Electroencephalogram, which is a test that measures electrical activity in the brain. This test is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. Choice B is incorrect as EEG is not a service but a diagnostic test. Choice C is incorrect as EEG does not monitor heartbeats. Choice D is incorrect as EEG has no relation to dentistry. EEG specifically focuses on brain activity, making choice A the most appropriate description.

Correct Answer: B

Rationale: The correct answer is B: Radius. In the forearm, the radius is shorter than the ulna. The radius is located on the same side as the thumb, while the ulna is on the side of the pinky finger. The humerus is the upper arm bone, the scapula is the shoulder blade, and the fibula is a bone in the lower leg. So, the radius is the only bone among the choices that is actually located in the forearm and is shorter than its counterpart, the ulna.
