NEX Exam Dumps : Nursing Entrance Exam (Math, Science and Verbal)

The alarm stage is the initial reaction to a stressor and is characterized by emotional outbursts, increased heart rate, and release of stress hormones such as adrenaline. The employee’s immediate anger and physical reaction reflect this stage. The resistance stage involves adaptation, and exhaustion occurs after prolonged stress. “Failure” is not a recognized stage of the stress response. The NEX Science exam frequently tests physiological and psychological responses to stress, making alarm the correct answer.

This is a percentage complement problem. If 7% of children have high cholesterol, then the remaining percentage with normal cholesterol is 100% − 7% = 93%. Convert 93% to a decimal by moving the decimal point two places to the left: 0.93. Multiply this decimal by the total number of children sampled: 0.93 × 120,000 = 111,600. Therefore, approximately 111,600 children would have normal cholesterol levels, making option D correct. Option A incorrectly calculates 7% instead of the complement. Option C represents 70%, not 93%. Option B is close but incorrect due to rounding. NEX math questions often assess whether students understand that “normal” refers to the remainder after subtracting the affected group.

This question asks for themain idea, which is the central message of the passage. The passage discusses several roles of water in the body, including temperature regulation, nutrient transport, and waste removal. It also highlights the effects of dehydration and the importance of monitoring fluid intake, particularly in older adults. All these details support one central idea: hydration is vital for maintaining overall health and proper body function. Option C correctly summarizes this main point. Option A is incorrect because the passage actually suggests older adults are at increased risk of dehydration. Option B contradicts the passage, which emphasizes water’s importance. Option D is incorrect because the passage notes that thirst may decrease with age and is not the only indicator. On the NEX exam, main-idea questions often require recognizing repeated themes across the passage rather than focusing on one detail.
