16. These structures keep the atrioventricular valves
from flipping back into the atria.
a. Chordae tendineae
b. Myocardial septa
c. Purkinje fibers
d. Semilunar cusps
Answer:
The structures that prevent the atrioventricular valves from reopening into the atria are called chordae tendineae (option a).
Explanation:
Tendinous cords, or chordae tendineae, are structures in the form of fibrous filaments that connect the atrioventricular valves to the papillary muscles of the ventricles.
The function of the chordae tendineae is to prevent the mitral and tricuspid valves from opening during ventricular contraction, preventing backflow of blood from the ventricles to the atria.
The chordae tendineae are predominantly made up of collagen and elastin, in addition to a small percentage of endothelium.
The other options are not correct because:
b. Myocardial septa is the division between the right and left ventricles.
c. Purkinje fibers are fibers that transmit the nerve impulse that allows ventricular contraction.
d. Semilunar cusps, correspond to the shape of the closed semilunar valves.

Which of the following statements is FALSE about alcohol?
Blood alcohol concentration slowly increases as it is absorbed from the stomach and the small intestine.
Appears in the blood a few minutes after it has been consumed
BAC levels are identical for all individuals who drink the same amount in a given time
Alcohol concentration slowly decreases until level returns to a zero.
Answer:
BAC levels are identical for all individuals who drink the same amount in a given time
BAC levels are identical for all individuals who drink the same amount in a given time. So, the correct option is (C).
What are BAC level?BAC stands for Blood Alcohol Content. It is also called blood alcohol concentration. It is described as a measure of the intoxication of an alcohol used for legal or medical purposes. It is expressed as mass per volume of alcohol or mass of blood.
Alcohol is the major intoxicant found in many intoxicated drinks. When we drink a beverage that contains alcohol, the stomach and small intestine rapidly absorb the alcohol and mix it into the bloodstream. Alcohol is toxic to the body, so when the liver metabolizes alcohol to filter it from the blood.
Levels can range from 0% (no alcohol) to over 0.4% (a potentially fatal level) which are not identical for all individuals who drink the same amount in a given time.
Thus, BAC levels are identical for all individuals who drink the same amount in a given time. So, the correct option is (C).

The refining process removes fiber and minerals in the bread. c. The bran that is kept in the refining process is harder to digest. d. The refining process creates products with higher levels of iron. e. The refining process calls for the addition of some added sugars.
Answer:
b. The refining process removes fiber and minerals in the bread.
Explanation:
The refined flour breads are considered less healthy than the whole grain breads because the refining process removes all the fibers and minerals from the bread. Thus, correct option is B.
What is refining process?Refining is a process by which natural foods are stripped which reduces the nutrient content of food. Refinement can even interfere with digestion.
The highly processed flour and additives in white bread are the refined foods. Consumption of too much of white bread can contribute to obesity, heart disease, and diabetes. Unrefined whole grains retain many of these vital nutrients and are rich in fiber, which helps your digestive system work well. Unprocessed foods contain fiber, vitamins, and minerals.
Processing food removes nutrients and results in refined carbs, which people also refer as empty carbs or empty calories. Refined carbs provide very few vitamins and minerals as compared to unrefined foods. Refined grains are milled to have the bran removed which is responsible for providing them a finer texture and extends the shelf life. Refined grains include white flour, white rice and white bread.
Therefore, correct option is B.

Membranes are sheets of tissue. Membranes cover surfaces, line body cavities, and surround organs. Membranes are classified as epithelial membranes or connective tissue membranes. The epithelial membranes include cutaneous (skin), mucous, and serous membranes. Explain how water and other nutrients move through memebranes.
Answer:
Water moves across a permeable barrier during osmosis to equalize the solute concentration on each side of the membrane. Nutrients, on the other hand, are absorbed across a barrier by a process known as diffusion
Explanation:
Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Diffusion is the process by which atoms or molecules move from an area of high concentration to low concentration

Pour 67 mL of juice followed by 29 mL of juice into a 100mL graduated cylinder what's the percent strength
Question Completion:
Pour 67 mL of Juice B followed by 29 mL of Juice A into the 100 mL graduated cylinder. What is the percent strength of each juice?
Answer:
The
percent strength of Juice B = 70%.
The percent strength of Juice A = 30%.
Explanation:
a) Data and Explanation:
Juice B = 67 mL
Juice A = 29 mL
Graduated Cylinder capacity = 100 mL
Total juice of B and A = 96 mL
The percent strength of Juice B = 70% (67/96)
The percent strength of Juice A = 30% (29/96)
b) The percent strength is the computation of how much of Juice A substance is dissolved into a specific amount of Juice B liquid. The percent strength establishes the part-to-whole relationships. A percent is a part of the 100 total parts. The 100 total parts in this case = 96 (67 + 29). Therefore, the part of Juice A in the total parts = 29/96 * 100 = 30% , while the part of Juice B in the total parts = 67/96 * 100 = 70%. Knowing the percent strength of each liquid helps to determine the content of each juice.

A nurse was reported to BON by two different employers regarding multiple practice errors.The nurses conduct demonstrates a pattern of practice
Unclear/incomplete question. However, I answered based on information provided by NURSING PEER REVIEW FREQUENTLY ASKED QUESTIONS of Texas Board of Nursing (May 2008)
Answer:
that suggests that the nurse lacks the knowledge and competencies needed.
Explanation:
Note, in this scenario we are told that the nurse had been reported by not just one employer, but two. This thus demonstrates that there is a growing pattern of bad clinal judgment practice by the nurse.
Hence, we can conclude that such multiple practice errors show that the nurse conduct is one that cannot be overlooked.
