A patient who is heedless is ___________.

Correct Answer: B

Rationale: Someone who is heedless is not paying attention or being cautious. Therefore, a patient who is heedless can be described as careless, as they may not be taking proper care or paying attention to important things that affect their well-being. Choice A, 'unlucky,' is incorrect as being heedless is not related to luck. Choice C, 'no longer in care,' is incorrect as it does not accurately reflect the meaning of heedless. Choice D, 'hard of hearing,' is unrelated to the concept of being heedless.

Correct Answer: B

Rationale: The word 'mercurial' in this sentence means unpredictable or prone to sudden changes in mood or behavior. Justin's temperament can be characterized as unpredictable, which is causing him to not work well with others. Choice A, 'Continuous,' does not align with the meaning of 'mercurial' as it implies a steady, uninterrupted flow. Choice C, 'Mercenary,' refers to being primarily motivated by money or reward, which is not the context here. Choice D, 'Miraculous,' means extraordinary or remarkable, which is not the intended meaning in this sentence.

Correct Answer: D

Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'

Correct Answer: D

Rationale: The correct meaning of 'disregard' in the sentence provided is 'to ignore.' When someone disregards something, they are choosing not to pay attention to it or consider it important. Choice A, 'Have no opinion about,' is incorrect as disregard implies actively ignoring something rather than having no opinion. Choice B, 'Pay attention to,' is the opposite of disregard. Choice C, 'Care for,' is also the opposite of disregard, as caring for something implies giving it importance and attention.

Correct Answer: C

Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.
