Which of the following selections lists conditions that would lead to increased stroke volume?
a) increased preload, increased afterload, increased contractility
b) decreased preload, decreased afterload, decreased contractility
c) increased preload, decreased afterload, increased contractility
d) decreased preload, increased afterload, increased contractility
e) increased preload, increased afterload, decreased contractility

Answers

Answer 1

Greater stroke volume would result from increased preload, decreased afterload, and increased contractility. So, option C is correct.

Medical emergencies include strokes. Stroke symptoms include difficulty speaking, understanding, and walking as well as paralysis or numbness in the face, arm, or leg.

Preload is the collective term for the elements that cause passive muscular tension in the muscles when they are at rest. At the conclusion of diastole, preload, which is proportional to end-diastolic volume, is the passive ventricular wall stress. In general, an increase in preload results in a rise in stroke volume.

Afterload takes longer for the heart to build up enough pressure to force open the aortic valve. As a result, less energy is expended ejecting the stroke volume and more energy is expended building up the pressure. This results in a reduction in the stroke volume.

The term "contractility" refers to the inotropy, or force, of myocyte contraction. The volume of the stroke grows as the heart's contraction force rises because it can force more blood out of the chambers.

A graph with two vertical axes is a type of graph that has two y-axes, one on each side of the graph, in order to display two different sets of data. The two different sets of data are related but have different units of measurement or vastly different values, and thus cannot be effectively compared on a single y-axis.

The use of two y-axes allows for both sets of data to be plotted and compared on the same graph, making it easier to understand the relationship between the two sets of data.

How long does it take for the person riding the Ferris wheel to make a complete revolution?

Answers

The time requires for the person riding the Ferris wheel to make a complete revolution is 26 sec.

To calculate the time required for a person riding the Ferris wheel to make a complete revolution first we need to write the equation of the Ferris wheel.

The equation of the Ferris wheel is

h(t) = a cos(b(t+c)) + d

Where

a = amplitude

b = angular frequency = 2pi/period

c = phase (horizontal) shift

d = vertical shift

For given equation: H(t) = 22 cos (π/13)t + 28, we have

Amplitude = 22

B = π/13

Phase shift = 0

Vertical shift = 28

Now the time required to make a complete revolution is

Period = 2π/B = 2π/(π/13) = 26 sec

Thus, the required time is 26 sec to make a complete revolution.

--The given question is incomplete, the complete question is

Decades ago, physicians could apply whatever treatment they felt was necessary to patients, many times without the patient’s permission or even knowledge of what was taking place. Most physicians did the very best for their patients, but some used this power to experiment with new ideas or procedures.

Now we have the Patient’s Bill of Rights.

QUESTION: Explain how the Patient’s Bill of Rights helps prevent unethical behavior among medical professionals today. Then give your opinion: Should a person always listen to the recommendation of their doctor in every situation? Give reasons for your answer.

Answers

Patient rights are a subset of human rights. Whereas the concept of human rights refers to minimum standards for the ways persons can expect to be treated by others, the concept of ethics refers to customary standards for the ways persons should treat others. As such, rights and ethics are usually flip sides of the same coin, and behind every ‘patient right’ is one or more ethical principle from which that right is derived. This activity discusses how the interprofessional team can ensure that ethical principles are followed and the patient's rights are assured. Establishing clearly defined patient rights helps standardize care across healthcare fields and enables patients to have uniform expectations during their treatment. According to the American Cancer Society, organizations should develop patient bills of rights “to empower people to take an active role in improving their health, to strengthen the relationships people have with their health care providers, [and] to establish patients’ rights in dealing with insurance companies and other specific situations related to health coverage.” As with other bills of rights, modern bills of patient rights establish that persons can expect certain treatment regardless of their socioeconomic status, religious affiliation, gender, or ethnicity. Commonly established rights tend to derive from a core set of ethical principles, including autonomy of the patient, beneficence, nonmaleficence, (distributive) justice, patient-provider fiduciary (trusting) relationship, and inviolability of human life. The establishment of whether one principle is of greater inherent value than another is a philosophical endeavor that varies from authority to authority. In many situations, beliefs may directly conflict with one another. When a legal standard does not exist, it remains the obligation of the health care provider to prioritize these principles to achieve an acceptable outcome for the patient. This essay analyzes patient rights with respect to their associated ethical principles with accompanying historical perspectives. It also specifies laws or the lack thereof that affect patient rights in the United States. Common sense dictates that rights established to preserve the well-being of an individual person do not always trump the well-being of a collective society. A recent applicable phenomenon includes measures that authorities take to minimize public disease caused by the SARS-CoV-2 virus (COVID-19), such as through the use of vaccines and respiratory tract masking.  Medical therapy essentially always involves a risk vs. benefit determination. The focus of this article is not to establish ethical and legal heuristics or algorithms for prioritizing measures designed to minimize risks to public health that concurrently expose individual persons to theoretical risks.

Answers

The value of x when we solve the equation using substitution method is 15.375.

Let the value of a = k/y² and b = m/y

Then,

x = k/y² + m/y + 4

18 = k/4 + m/2 + 4

14 = k/4 + m/2

56 = k + 2m ---- (eq 1)

-3 = k + m + 4

-7 = k + m ---- (eq 2)

Subtracting equation 1 from equation 2

56 - (-7) = 2m - m

m = 63  

Substituting the value of m in equation 2

-7 = k + 63

k = -70

Putting the value of k in x = k/y² + m/y + 4

x = -70/16 + 63/4 + 4
