The nurse is to administer a potassium supplement to the client and does not check the potassium level prior to administering the medication and later finds that the potassium level was at a critical high which means that the nonmaleficence principle was violated which is denoted as option B.
<h3>What is Nonmaleficence? </h3>
This refers to the duty of a professional such as healthcare workers in ensuring that there is no harm done to the client or patient.
In this scenario, negligence caused the nurse to administer a medication which had a critically high amount of potassium which is harmful to the body.
This is therefore the reason why nonmaleficence was chosen as the correct choice.

The answer is <u>bleeding.</u>
<u />
Risk the nurse is trying to prevent is bleeding.
What is bleeding?
Blood loss from the circulatory system is referred to as bleeding. Small cuts and abrasions to severe cuts and amputations are examples of possible causes. Body injuries can also cause internal bleeding, which can range in severity from modest (visible as superficial bruising) to significant hemorrhage.
In order to stop serious external or internal bleeding while waiting for emergency medical assistance, first aid is essential. Applying direct pressure to the wound, maintaining the pressure using pads and bandages, and, if feasible, lifting the damaged limb above the level of the heart are all first aid measures to manage external bleeding.

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.
SORRY ITS A LONG ANSWER!!!
Answer:
It authorized grants to develop a comprehensive EMS system throughout the country, for feasibility studies and planning, for the establishment and initial operation of EMS systems, and for the expansion and improvement of current systems. To have trained personnel respond quickly and provide emergency care on the scene, during transport, and at the hospital.
Explanation:
The client should be helped to sit at the edge of the bed while leaning forward and supporting their arms on a bedside table, a pillow, or a folded towel since a needle will be put into the intercostal area during a thoracentesis.
<h3>Which of the following observations demonstrates that the patient is having respiratory problems?</h3>
Observe the depth of breathing and make a note of whether it is shallow or deep. Breathing difficulties can be detected by symptoms such pursed-lip breathing, nasal flaring, audible breathing, intercostal retractions, anxiousness, and the usage of auxiliary muscles.
A significant air leak between the drain and the patient is indicated by the chamber's persistent bubbling. Examine the drain for disconnections, dislodgments, and loose connections while evaluating the patient's condition. If the issue cannot be fixed, notify medical personnel right away.
