Pass the NLN Nursing Education Program NEX Questions and answers with ExamsMirror

“Reluctant” describes someone who is unwilling or hesitant to act. Option C best matches this meaning. The other options suggest eagerness or readiness, which are opposites. Context clues on the NEX often rely on emotional tone.

The passage distinguishes between short-term and chronic stress. While short-term stress may increase alertness, chronic stress is associated with negative health effects. One of the effects specifically mentioned is increased blood pressure. Option C is therefore correct. Options A and D describe benefits not associated with chronic stress in the passage. Option B is incorrect because the passage states that chronic stress weakens, rather than strengthens, the immune system. The NEX exam often includes questions that test the ability to identify contrasting ideas within a passage, such as short-term versus long-term effects.

To observe means to watch carefully or notice attentively. Option A best matches this definition. In healthcare contexts, observation is a critical skill, making this a high-yield NEX vocabulary term.

Evaluate means to assess, judge, or determine the value or effectiveness of something. Option B is the correct synonym. Evaluation is a common term in healthcare and academic settings, making it a high-yield NEX word.

“Frequent” means occurring often or regularly. Option B is correct. Recognizing time- and frequency-related words is common on the NEX exam.

======

The passage states that lack of sleep weakens immune function and increases susceptibility to illness. This supports the conclusion that adequate sleep supports immune health. Option C accurately reflects this relationship. Options A and D contradict the passage, while option B exaggerates the effect. NEX questions often test the ability to infer logical conclusions without overgeneralizing.

This question tests knowledge of spinal anatomy and the ability to interpret labeled diagrams, which is common on the NEX Science exam. The vertebral column is divided into regions: cervical (neck), thoracic (upper and mid-back), lumbar (lower back), sacral, and coccygeal regions. In the image, bracket B corresponds to the long middle portion of the spine where ribs attach. This region contains the thoracic vertebrae, which are larger than cervical vertebrae but smaller than lumbar vertebrae and are uniquely characterized by rib articulation. The sacral region is located below the lumbar spine and consists of fused vertebrae, while the cervical region is at the top of the spine near the skull. The lumbar region is shorter and thicker, designed to support body weight. Because bracket B shows the rib-bearing portion of the spine, the correct answer is thoracic. The NEX often assesses spatial understanding of skeletal structures using diagrams.

Oxygen is produced during the process of photosynthesis, which occurs in the chloroplasts of plant cells. During photosynthesis, plants use carbon dioxide, water, and light energy to produce glucose and oxygen. Carbon dioxide is one of the key raw materials required for this process. When the availability of carbon dioxide increases, the rate of photosynthesis can also increase, assuming that light and water are not limiting factors. As photosynthesis increases, more oxygen is released as a byproduct. Decreasing carbon dioxide would slow photosynthesis and reduce oxygen production. Glucose is a product of photosynthesis, not a reactant, so changing glucose levels does not directly increase oxygen output. Therefore, increasing available carbon dioxide is the correct answer. The NEX Science exam frequently tests understanding of the inputs and outputs of photosynthesis and how environmental factors affect the process.

Combining disease prevention and health promotion provides the greatest overall impact on reducing cardiovascular disease. Prevention identifies and manages risk factors early, while health promotion encourages long-term lifestyle changes such as healthy eating, exercise, and stress reduction. Education alone increases awareness but may not change behavior. Screening without lifestyle intervention has limited long-term effectiveness. The NEX Science exam emphasizes population health strategies, making integrated prevention and promotion the most effective approach.

Negative feedback occurs when a change in a physiological variable triggers a response that counteracts the initial change, helping maintain homeostasis. When blood glucose levels rise, the pancreas releases insulin, which promotes glucose uptake by cells and lowers blood glucose back to normal levels. This is a classic example of negative feedback. Option B is incorrect because thyroxine increases metabolism, not decreases it. Options A and D do not clearly demonstrate a direct feedback loop restoring balance. The NEX Science exam often highlights glucose regulation as a key example of negative feedback because it clearly illustrates cause-and-effect relationships within endocrine control systems.
