Question 13 of 25

In a group there are 12 RNs and 8 LPNs. A student represents the RN-to-LPN ratio as the fraction 12/8 and does not simplify it. A classmate claims a fraction must compare a part with the total group, so the correct fraction should be 12/20. Which statement best identifies the error?

A.Ratios may never be written as fractions.B.The classmate is correct; 12/20 is the only possible ratio.C.The classmate is wrong; the ratio compares RNs to LPNs, and 12/8 simplifies to 3:2.D.The first student should have inverted the fraction to 8/12.

A.Atrioventricular valves have cords that anchor them to the ventricular wall, while semilunar valves open and close solely because of pressure changes.B.Atrioventricular valves connect the ventricles to the great arteries, while semilunar valves connect the atria to the ventricles.C.Atrioventricular valves are open during ventricular systole, while semilunar valves are closed during ventricular diastole.D.Atrioventricular valves prevent blood from moving backward into the atria, while semilunar valves prevent blood from moving backward into the ventricles.

Question 20 of 25

A student writes 5/8 as 0.625. Which check correctly supports this result?

A.Since 5/8 is close to 1, the decimal should be close to 1.0, so 0.625 is an overestimate.B.Since 1/8 = 0.8, five times that amount is 4.0, so 0.625 cannot be correct.C.Since 5/8 is less than 1/2, the decimal must be less than 0.5.D.Since 5/8 is greater than 4/8, which equals 0.5, the decimal should be greater than 0.5; 0.625 satisfies that check.

Question 21 of 25

During a TEAS Reading practice session, a student answers one passage with very different question types. Some questions ask for dates and names, another asks what a sentence implies. What is the most effective approach?
