The scientific method for investigating phenomena proposes that all established knowledge is: (QID 113808)

A. indisputable B. intellectual C. questionable D. intuitive

Extra-terrestrial life forms are thought to exist by many, including some notable scientist. Outer space and Mars missions have provided evidence of organic gases only capable of being produced by life forms though no extra-terrestrial life forms have ever been observed directly. Which of the following is a logical explanation for upholding the theory that life forms other than terrestrials exist? (QID 113807)

A. In science all possibilities are inherently correct until disproven.
B. The existence of humans and other terrestrial life forms invariably means other
non-terrestrial life forms must exist.
C. The sun provides radiant energy to Earth and Mars; therefore, life must exist on
Mars as it does on Earth.
D. Empirical observations provide a basis for further exploration and scientific analysis.

Atherosclerosis is hardening of the arteries from cholesterol plaque build-up and deposition inside the blood vessel. Diabetes, inappropriately elevated blood glucose levels, exacerbated the progression of atherosclerosis. Which of the following diseases could result from a person having both diseases? (QID 113806)

A. AIDS B. angina C. HPV induced cervical cancer D. tuberculosis

A world-renown research group had a very promising finding on the first attempt of an experiment. After expert evaluation, the research group would like to improve the accuracy and precision of its experimental results. Which of the following is the best method to achieve this goal? (QID 113805)

A. Repeating the experiment once under multiple experimental conditions.
B. Repeating the experiment once again under the same experimental conditions.
C. Repeated experiments under only one experimental condition.
D. Repeated experiments under multiple varying experimental conditions.

Researchers have surveyed thousands of years of surface temperature records and have noted very minor fluctuations in Earth’s temperature during the period. What accounts for this observation? (QID 113804)

A. The equilibrium established from the absorption of the sun’s radiant energy and the
Earth’s electromagnetic wave emissions sustains a consistent atmospheric
B. The vast oceans consuming 66% of the Earth absorb the majority of solar radiation.
C. Thermal energy production from photosynthesis and cellular respiration sufficient
warms the Earth’s atmosphere with a constantly accumulation of heat.
D. The sun’s constant radiant energy provides sustained heat to the Earth atmosphere.

Which of the following provides the most direct assessment of your patient’s hyperglycemic status today? (QID 113803)

A. Count the caloric consumption of his monthly carbohydrate intake.
B. Obtaining empirical data on non-enzymatic glycosylation of hemoglobin
C. Observing a finger-stick glucometer reading taking prior to this appointment.
D. Assessing glucose and protein production in his urine on today’s office visit.

Which of the following answer choices provide the best rational for why temperatures on earth vary by season annually? (QID 113802)

A. The sun’s radiant energy travels with a more potent thermal force during summer.
B. The radiant energy from the sun varies with each axial rotation of the Earth.
C. Earth’s atmospheric ozone layer preferentially deflects solar radiation in the winter.
D. The radius of Earth’s oval, orbital rotation around the sun varies seasonally with a
longer oval radius during the winter.

As a nurse, you are following your patient’s systolic and diastolic blood pressure. Over the last 12 hours with the appropriate treatment, you have noted a gradual decline in your patient’s blood pressure who was experiencing a hypertensive emergency. Which type of graph would you use to plot your patient’s blood pressure over the last 12 hours? (QID 113801)

A. Pie Chart B. Venn Diagram C. Line Graph D. Histogram
