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).
Answer:
Mistletoe is a parasite – it steals water and nutrients from trees. Technically, it is a “hemiparasite”, which means that it can generate some of its own resources through photosynthesis – it just needs that energetic kick from the sun to fuel the biological siege and subsequent invasion of the tree
Explanation:
Answer:
it reflects green light and absorbs other colors.
Explanation:
The term pigment derives from the Latin pigmentum, which means the <em>substance that produces color</em>.
Pigments provide color to cells and tissues.
In vegetables, we can find different pigments, such as chlorophyll or carotenoids, among others. Plants use these pigments during the photosynthesis process to absorb sunlight and fixate carbon dioxide. Stem, flowers, and other tissue have pigments in their cells that define the organ´s colors.
Pigments are chemical molecules that produce color by the selective absorption of sunlight. Whenever white light meets a pigment, some wavelengths are absorbed by the pigments while others are reflected. The color expressed is the product of the reflection. The reflected spectrum is perceived as color and determined to be the pigment color or the color of an object or organism.
The color that tissue or vegetal organ express will depend on the pigment concentration or the combination of many of them.
The green color is ordinary in most vegetable species. Chlorophyll is responsible for this coloration, present in almost every vegetable species. This pigment absorbs blue and red wavelengths. But they reflect spectrums of green wavelengths, meaning that the expressed color is green in different tones.
Abnormal softening of a gland is known as the adenomalacia.
