HESI A2 Vocabulary Quiz

Correct Answer: A

Rationale: The correct answer is A: convulsion. A paroxysm is defined as a sudden and uncontrollable spasm or seizure, which aligns with the definition of a convulsion. This term specifically refers to a sudden, violent, and involuntary contraction of muscles. The other choices are incorrect because they do not directly relate to the sudden spasm described in the question. B: symptom is a general term for any indication of a disease or condition, not specifically a sudden spasm. C: efficacy refers to the ability of something to produce a desired or intended result, which is unrelated to the concept of a sudden spasm. D: embolism is a medical condition where a blood clot or other substance blocks a blood vessel, which is not synonymous with a sudden spasm.

Correct Answer: D

Rationale: The correct answer is D: Confinement away from the general population. In the given sentence, 'quarantine' refers to isolating individuals to prevent the spread of a contagious disease. This choice aligns with the context, as patients are being separated for public health reasons. A: A specialist's care is incorrect as it does not reflect the concept of isolation. B: Experimental drug therapy is irrelevant to the context of quarantine. C: Imprisonment in a rehabilitation unit is not the intended meaning, as quarantine is a temporary measure for public safety.

Correct Answer: D

Rationale: The correct answer is D: burn it. Cauterizing a wound involves using heat or a chemical to burn the tissue in order to stop bleeding or prevent infection. This process seals the blood vessels and tissues, aiding in the wound's healing. The other choices are incorrect because: A: Soothing a wound does not involve burning or sealing the tissue. B: Covering a wound with a bandage does not involve burning the tissue. C: Stitching a wound involves sewing it closed, not burning the tissue.

Correct Answer: A

Rationale: The correct answer is A: Mostly. 'Principally' typically means mainly or primarily. It is used to indicate the most important aspect or the primary reason for something. In this context, it implies that something is primarily or predominantly the case. The other choices are incorrect because 'clearly' (B) means obviously or without doubt, 'in our opinion' (C) suggests a personal viewpoint, and 'royally' (D) refers to something related to royalty or in a regal manner, none of which align with the meaning of 'principally.'

Correct Answer: D

Rationale: The correct answer is D: Fragments. 'Disintegrates' means to break into small pieces or fragments. In the context of the sentence, the substance breaks down into smaller pieces in the mouth for easy swallowing. A: Evaporates means turning into vapor, not applicable here. B: Fizzes means bubbling or hissing sound, not related to breaking into pieces. C: Deviates means to depart from a standard or path, not relevant to the context.
