1 answer:
san4es73 [151]3 years ago
5 0

Answer:

The given statement is TRUE

Explanation:

Friction is a force experienced by a body that resists its motion.

In other words, Friction is the force experienced by the two bodies (with uneven or rough surfaces) when moving against each other.

When an object slides on a surface, the surface area of the object in contact with the surface is more as compared to an object which is rolled on the surface. Therefore, the friction force experienced by the sliding body is greater than the rolling body.

Therefore, we can say that the rolling friction is less than the sliding friction.

To test cranial nerves III, IV, and VI (oculomotor, trochlear, and abducens) together.

Test the eye movement with a penlight. Stand 30 cm in front of the patient and ask them to follow the direction of the penlight with their eyes only. At eye level, move the penlight left to right, right to left, top to bottom, top right to bottom left, and top left to bottom right. Also, pay attention to eye movements in all fields. An unexpected finding is an involuntary eye tremor called nystagmus.

Test the pupils on both sides to make sure they are evenly rounded and respond to light and accommodation. Dim the lights in the room before running this test. The pupil should be round and the same size on both sides.

A patient with persistent, frequent asthma exacerbations asks a nurse about a long-acting beta2-agonist medication. What will th
Black_prince [1.1K]

A nurse is questioned about a long-acting beta2-agonist drug by a patient who experiences persistent, recurrent asthma exacerbations. As prophylactic, the glucocorticoid is used to stop exacerbations.

  • Asthma is a chronic respiratory disease that affects a lot of people. In wealthy nations, it is viewed as a major cause of morbidity and a major contributor to the high cost of healthcare.
  • The two main pathogenic characteristics of asthmatics' airways are inflammation and hyperresponsiveness.
  • Treatment for asthma should be intensified gradually in order to regulate the condition, both for symptom relief and to avoid exacerbations.
  • This methodical approach, which begins with low dose inhaled corticosteroids and progresses, if necessary, to inhaled corticosteroids combined with long-acting -agonists, will control the majority of instances of asthma.

An African American young adult is admitted to the emergency department in sickle cell crisis with a report of 10/10 pain. The p
vivado [14]

Answer:

The situation of a patient with sickle cell anemia, and especially when facing a sickle cell crisis, is critical in regards to the level of pain that these patients experience. There are those whose pain is acute, while others suffer it chronically, and yet others with a mixture of both. Some patients, who do not develop tolerance to pain medication, such as opioids, will only seek pain relief help when the pain, caused by infarction of the tissues due to the occlusions caused by the disease, in vessels, and thus tissues, gets intense. However, there are people who become tolerant, and begin to become known by healthcare professionals as "drug seekers". The problem here is the lack of knowledge on the part of professionals, on how pain can affect the person, and how pain is felt differently depending on the person and the severity of the lession caused by an occlusion. This lack of proper knowledge is what leads some professionals to judge the person who constantly alters his level of pain perception to justify being given more medication.

However, the nursing staff here plays a critical role in two ways, first, ensuring education of the patient on the different ways that pain can be managed by the patient, without becoming oversdosed on opioids, and the second, on educating the personnel who works with these patients.

As such, one intervention would be to teach the patient about the different types of pain relievers that he can use, that will at least soften the pain. But more importantly, there is work to be done, on the part of the nurse, on teaching the patient how to handle pain without any medication, and there are breathing techniques, and meditation techniques, that will help the patient learn to place his/her pain in the proper proportion, before doping himself/herself with opioids.

But in response to the second question, the intervention of the nurse must be on both the patient and the team that works with the patient. As said before, education is the key, and this is a vital role of nurses. The nurse must also ensure that her team learns about how the disease works, where the pain comes from, why this patient is constantly seeking pain meds, and how each of the team members can play their own role in helping the patient manage his pain.
