                            NLN Nursing Entrance Exam (Math, Science and Verbal) Sample Questions (Q134-Q139):

                            NEW QUESTION # 134
                            Which organ system can alter the amount of CO# in the blood?

                            Answer: B

                            Explanation:
                            The respiratory system directly regulates the level of carbon dioxide (CO#) in the blood. CO# is a waste product of cellular respiration and is removed from the body through exhalation. When breathing rate increases, more CO# is expelled, lowering blood CO# levels. When breathing slows, CO# levels rise. While the cardiovascular system transports CO#, it does not regulate its concentration. The urinary system regulates pH and fluid balance but does not directly remove CO#. The endocrine system controls hormones, not gas exchange. The NEX Science exam frequently emphasizes the role of the respiratory system in maintaining acid-base balance through CO# regulation.


                            NEW QUESTION # 135
                            Word Knowledge
                            The word"fatigue"most nearly means:

                            Answer: C

                            Explanation:
                            Fatigue refers to extreme tiredness or exhaustion. Option C correctly matches this meaning. NEX exams often include common clinical terms like fatigue.

                            NEW QUESTION # 136
                            Which of the following pictures reflects the effect on red blood cells when plain water is infused into a person?

                            Answer: D

                            Explanation:
                            This question tests understanding of osmosis and tonicity, which are frequently assessed on the NEX Science exam, especially in physiology-related contexts. Plain water ishypotoniccompared to the fluid inside red blood cells. When red blood cells are placed in a hypotonic solution, water movesintothe cells by osmosis because water flows from an area of lower solute concentration to higher solute concentration. As water enters the red blood cells, they swell. If too much water enters, the cells can burst in a process calledhemolysis
                            . The correct image therefore shows enlarged, rounded red blood cells that may appear ruptured. Normal biconcave cells indicate an isotonic environment, while shriveled or spiky cells occur in a hypertonic solution.
                            Sickle-shaped cells are related to a genetic disorder and are not caused by osmotic changes. The NEX exam often emphasizes patient safety concepts, including why plain water should never be infused intravenously.


                            NEW QUESTION # 137
                            There are four drinks on sale:
                            * 20 ounce cup for $4.00
                            * 12 ounce cup for $3.00
                            * 10 ounce cup for $2.50
                            * 8 ounce cup for $2.40
                            Which drink is the most expensive price per ounce?

                            Answer: A

                            Explanation:
                            This question tests unit rate comparison, which is common on the NEX exam. To find the price per ounce, divide the cost by the number of ounces for each drink. For the 20-ounce cup: $4.00 ÷ 20 = $0.20 per ounce.
                            For the 12-ounce cup: $3.00 ÷ 12 = $0.25 per ounce. For the 10-ounce cup: $2.50 ÷ 10 = $0.25 per ounce. For the 8-ounce cup: $2.40 ÷ 8 = $0.30 per ounce. The most expensive price per ounce is $0.30, which corresponds to the 8-ounce cup. Therefore, option B is correct. The NEX frequently includes comparison problems that require calculating unit rates rather than comparing total prices. Always divide cost by quantity to ensure an accurate comparison.


                            NEW QUESTION # 138
                            The thymus, lymph nodes, and spleen are all organs of which system?

                            Answer: D

                            Explanation:
                            The thymus, lymph nodes, and spleen are key components of the immune system. The immune system is responsible for defending the body against pathogens such as bacteria, viruses, and other foreign invaders.
                            The thymus plays an important role in the maturation of T lymphocytes (T cells), which are critical for adaptive immunity. Lymph nodes filter lymphatic fluid and trap pathogens, allowing immune cells to recognize and respond to infections. The spleen filters blood, removes old or damaged red blood cells, and helps initiate immune responses to blood-borne pathogens. While the endocrine system regulates hormones, the cardiovascular system transports blood, and the integumentary system protects the body externally, none of these systems include the thymus, lymph nodes, and spleen as primary organs. The NEX Science exam often tests system identification by grouping organs with shared functions, making the immune system the correct choice.
