Ede4ka [16]

An ongoing clinical protocol at your site includes weekly blood draws to assess an exploratory endpoint. Unfortunately, participants are not happy about visiting the clinic weekly, and they are considering dropping out. Therefore, a protocol amendment is being prepared to remove the weekly blood draw. This change can be implemented once the protocol is finalised and submitted to the FDA.

<h3>What is the FDA?</h3>

The Federal Food and Drugs Act, which was passed in 1906, led to the creation of the Food and Drug Administration (FDA). The organisation is divided into divisions, each of which is in charge of the majority of the organisation's responsibilities relating to food, medicines, cosmetics, animal food, nutritional supplements, medical devices, biological products, and blood products.

The FDA is renowned for its efforts to control the creation of new medications. All new pharmaceuticals must undergo clinical trials, according to regulations set down by the FDA. Before medicines may be offered to humans, pharmaceutical companies must put them through four stages of clinical testing.

1. The nurse is teaching a group of students about the differences between a full-term newborn and a preterm newborn. The nurse
andreyandreev [35.5K]

The nurse determines that the teaching is effective when the students state that the preterm newborn has greater surface area in proportion to weight. The correct option is D.

<h3>What is a preterm newborn?</h3>

Preterm babies are those born early before the 37th week of pregnancy. Preterm birth is split into subcategories based on gestational age: exceptionally premature less than 28 weeks extremely premature 28 to 32 weeks

Premature babies may experience more health problems at conception and later in life than full-term babies.

Premature babies are more likely to have long-term intellectual and developmental disabilities, as well as issues with their lungs, brain, eyes, and other organs.

When the educators state that the preterm newborn has a larger surface area in proportion to weight, the nurse knows the teaching is effective.

Thus, the correct option is D.

Compare the two theories of color perception are they completely different
galben [10]
We do not see the world in black and white; neither do we see it as two-dimensional (2-D) or flat (just height and width, no depth). Let’s look at how color vision works and how we perceive three dimensions (height, width, and depth).
Color Vision
Normal-sighted individuals have three different types of cones that mediate color vision. Each of these cone types is maximally sensitive to a slightly different wavelength of light. According to the trichromatic theory of color vision, shown in Figure 1, all colors in the spectrum can be produced by combining red, green, and blue. The three types of cones are each receptive to one of the colors.
The trichromatic theory of color vision is not the only theory—another major theory of color vision is known as the opponent-process theory. According to this theory, color is coded in opponent pairs: black-white, yellow-blue, and green-red. The basic idea is that some cells of the visual system are excited by one of the opponent colors and inhibited by the other. So, a cell that was excited by wavelengths associated with green would be inhibited by wavelengths associated with red, and vice versa. One of the implications of opponent processing is that we do not experience greenish-reds or yellowish-blues as colors. Another implication is that this leads to the experience of negative afterimages. An afterimage describes the continuation of a visual sensation after removal of the stimulus. For example, when you stare briefly at the sun and then look away from it, you may still perceive a spot of light although the stimulus (the sun) has been removed. When color is involved in the stimulus, the color pairings identified in the opponent-process theory lead to a negative afterimage. You can test this concept using the flag in Figure 2.
But these two theories—the trichromatic theory of color vision and the opponent-process theory—are not mutually exclusive. Research has shown that they just apply to different levels of the nervous system. For visual processing on the retina, trichromatic theory applies: the cones are responsive to three different wavelengths that represent red, blue, and green. But once the signal moves past the retina on its way to the brain, the cells respond in a way consistent with opponent-process theory (Land, 1959; Kaiser, 1997).
Depth Perception
Our ability to perceive spatial relationships in three-dimensional (3-D) space is known as depth perception. With depth perception, we can describe things as being in front, behind, above, below, or to the side of other things.

Our world is three-dimensional, so it makes sense that our mental representation of the world has three-dimensional properties. We use a variety of cues in a visual scene to establish our sense of depth. Some of these are binocular cues, which means that they rely on the use of both eyes. One example of a binocular depth cue is binocular disparity, the slightly different view of the world that each of our eyes receives.
A 3-D movie works on the same principle: the special glasses you wear allow the two slightly different images projected onto the screen to be seen separately by your left and your right eye.
Although we rely on binocular cues to experience depth in our 3-D world, we can also perceive depth in 2-D arrays. Think about all the paintings and photographs you have seen. Generally, you pick up on depth in these images even though the visual stimulus is 2-D. When we do this, we are relying on a number of monocular cues, or cues that require only one eye. If you think you can’t see depth with one eye, note that you don’t bump into things when using only one eye while walking—and, in fact, we have more monocular cues than binocular cues.
An example of a monocular cue would be what is known as linear perspective. Linear perspective refers to the fact that we perceive depth when we see two parallel lines that seem to converge in an image (Figure 3).
Vision is not an encapsulated system. It interacts with and depends on other sensory modalities. For example, when you move your head in one direction, your eyes reflexively move in the opposite direction to compensate, allowing you to maintain your gaze on the object that you are looking at. This reflex is called the vestibulo-ocular reflex. It is achieved by integrating information from both the visual and the vestibular system (which knows about body motion and position). You can experience this compensation quite simply.
Finally, vision is also often implicated in a blending-of-sensations phenomenon known as synesthesia.
