The question is incorrect. The correct question is as follows:
The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?
a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."
b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."
c. "Her alveoli have been damaged and may rupture with higher doses of O2."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
Answer:
Her respiratory center requires low O2 concentration to stimulate breathing."
Explanation:
COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.
The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.
Thus, the correct answer is option (d).
B. Small Veins
C. Lymph vessels
D. Heart atria
Blood normally flows from the capillaries directly into Small Veins. Thus, option B is correct.
The Small varicose veins called spider veins show up as thin, wavy lines directly beneath the skin. They typically afflict women and are particularly prevalent on the face and legs.
Blood pooling in veins close to the skin's surface causes spider veins. Venules, which are incredibly tiny blood channels, link the capillaries and veins throughout the body.
The venules play a crucial role in transferring blood from the capillaries to your veins that is depleted of oxygen and contains trash. The blood can return to the heart from that point on.
Therefore, option B is correct.

When he discovered that blood is pumped from the heart to the body, and back to the heart, William Harvey had a difficult time getting people to accept his discovery because it went against the ancient teachings of Galen.
blood is a fluid connective tissue contain blood cells and an plasma.
The major functions include transportation and providing immunity and protection.
The major components include plasma primary constituent of blood contain 55 percent of blood volume. It is made up of water, salts, proteins, and blood cells.
Red Blood Cells which determine blood type, biconcave in shape, enucleated contain millions of hemoglobin molecules.
White Blood Cells act as defensive cell in the immune system and lymphatic system against infection.
Platelets are formed from pieces of cells present in the bone marrow called megakaryocytes.

Answer:
1 - William Harvey
2 - Galen
Explanation:
Galen, who postulated that blood was produced continuously in the liver and absorbed by the body (not recirculated), served as the Roman emperor's personal physician. For 1500 years, his theories about human anatomy went unquestioned until Harvey's proposal in 1628.
Answer:
the other dude did 9- not 8..
Explanation:
b. Humans need a constant supply of water to maintain proper hygiene.
c. Constant supplies of freshwater are needed because body water is continually being lost.
d. Constant supplies of freshwater are not actually necessary for survival.
Constant supplies of freshwater are needed because body water is continually being lost through metabolic processes etc.
This is referred to as a universal solvent and is composed of the chemical elements hydrogen and oxygen.
Water is useful in the body's metabolic processes such as digestion and homeostasis. Water is also lost through evaporation which is why it must be constantly supplied and the reason option C was chosen.

When chemical, biological and ecological changes occur the plants start to die and decompose, fish die, carbon dioxide is released. Hence the correct option is B.
Ecological change also known as environmental change is defined as the alteration or disturbance of the environment usually caused by human impacts and natural ecological processes. Environmental changes include various factors, such as natural disasters, human interference, or animal interactions.
The ecological changes are affected by the following reasons such as habitat change, climate change, invasive species, overexploitation, and pollution. When chemical, biological and ecological changes occur the plants start to die in the pond and start to decompose, fish die, carbon dioxide is released.
Hence the correct option is B.

Artificial selection
(Choice B)
B
Natural selection
(Choice C)
C
Environmental selection
(Choice D)
D
Sexual selection
Choice A, artificial selection, led to the presence of these traits in French bulldogs.
Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.
Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.
Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.
In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.
