NLN Nursing Entrance Exam (Math, Science and Verbal) Sample Questions (Q45-Q50):

NEW QUESTION # 45
During prolonged, strenuous physical activity, muscle cells undergo a type of anaerobic respiration that produces

Answer: D

Explanation:
When oxygen levels are insufficient during intense exercise, muscle cells switch from aerobic respiration to anaerobic respiration. In this process, pyruvic acid is converted into lactic acid. The production of lactic acid allows glycolysis to continue generating ATP in the absence of oxygen. However, lactic acid buildup contributes to muscle fatigue and soreness. Carbon dioxide is primarily produced during aerobic respiration, and hydrogen ions are a byproduct but not the main substance emphasized in anaerobic respiration. The NEX Science exam frequently tests metabolic pathways related to exercise and energy production, making lactic acid the correct answer.


NEW QUESTION # 46
Word Knowledge
The word"essential"most nearly means:

Answer: D

Explanation:
"Essential" means absolutely necessary or vital. Option C is the correct synonym. The other options are opposites or unrelated. Essential is a high-frequency NEX word, especially in health and science contexts.


NEW QUESTION # 47
Reading Comprehension
Passage:
Vaccination programs rely on widespread participation to be effective. When a large portion of the population is vaccinated, herd immunity helps protect individuals who cannot be vaccinated.
What is the primary benefit of herd immunity?

Answer: D

Explanation:
The passage explains that herd immunity occurs when a large percentage of the population is vaccinated, which helps protect those who cannot receive vaccines. Option B correctly states this benefit. The passage does not suggest that herd immunity eliminates all diseases or replaces hygiene practices. It also does not mention reducing side effects. On the NEX exam, cause-and-effect questions require identifying the specific outcome discussed rather than making broad assumptions. Herd immunity's protective effect on vulnerable individuals is the key idea.

NEW QUESTION # 48
A doctor lowered a patient's dosage from 50 mg to 40 mg. What percent decrease was this?

Answer: A

Explanation:
This question tests percent decrease, a common NEX topic. First find the amount of decrease: 50 mg # 40 mg
= 10 mg. Next divide the decrease by the original amount:
10 รท 50 = 0.2.
Convert the decimal to a percent by multiplying by 100:
0.2 ร— 100 = 20%.
Therefore, the correct answer is B. Option D represents the numerical decrease without considering the original value. Option A and C result from incorrect division. On the NEX exam, percent change problems always use the original value as the denominator.


NEW QUESTION # 49
The figure below represents the human eye.

Where are the rods and cones located?

Answer: C

Explanation:
Rods and cones are specialized photoreceptor cells responsible for vision. These cells are located in the retina, the innermost layer of the eye. The retina contains multiple layers of cells that convert light energy into electrical impulses, which are then transmitted to the brain through the optic nerve. Rods are highly sensitive to light and are essential for vision in dim conditions, while cones are responsible for color vision and sharp visual detail. The cornea and lens help focus light but do not detect it. The optic nerve transmits signals but does not contain photoreceptors. The NEX Science exam frequently tests eye anatomy and sensory physiology, especially the relationship between structure and function. Correctly identifying the retina as the location of rods and cones is essential for understanding how visual perception occurs.
