Which of the following is true?*
5 points
The waves in the ECG cycle represent the number of heartbeats.
The time of electrical recovery in the ventricles before a new heartbeat starts is
known as ventricular depolarization.
Electrical impulses in the heart cause the muscle to contract.
Muscle tissue in most body organs are able to stimulate their own contractions.
Answers
Answer:
1. Electrical impulses in the heart cause the muscle to contract.
2. To keep the blood flowing in only one direction
Explanation:
In the first question, the correct answer is ''Electrical impulses in the heart cause the muscle to contract''. Every muscle in our body contracts because of electrical impulses and this is also true for our hearts. Or any hearts in nature that we know of.
In the second question, the answer is ''To keep the blood flowing in only one direction''. We have those valves and without them, we wouldn't be able to function as we do.

Imagine that Brianna is working as a nurse in a hospital. As she walks down
the hall, a doctor stops her and says he has to report for an emergency on
another floor, and he asks that she insert a new central line for his patient's IV
medication. Brianna's familiar with the procedure and has the free time, so
she happilyjagrees to help. She enters the patient's room, introduces herself,
and explain's the situation and the procedure. The patient already has a
venous catheter no longer delivering medication on the left side of his chest,
so Brianna decides to enter the central line into his jugular vein on the right
side of his neck. Following safety protocols, she washes her hands, cleans
the skin with chlorhexidine, and then uses full-barrier precautions when
inserting the new line. Right as she finishes and says goodbye to the patient,
the doctor walks back into the room. He talks to the patient for a moment,
and then looks at Brianna, clearly disappointed. What did Brianna do wrong
and why did this increase risk to the patient?
Answers
Answer:
Before beginning to insert the new central line, Brianna failed to remove the original central line in the patient's chest. This can add to the patient's risk of infection.

The subsystems comprising the outermost layer of a person’s environment are ------- systems.
-macro

Answers
Answer:
macrosystem
Explanation:
The question above is related to "Bronfenbrenner's Ecological Systems Theory," which talks about the different structures of environment that could affect the development of a child. The systems are the following: Macrosystem, Microsystem, Exosystem and Chronosystem.
The "Macrosystem" is considered the outermost layer. It includes the customs, laws and cultural values. For example, if a society believes that education is very important for children, then they'd most likely prioritize building schools and providing educational assistance. This has a cascading effect towards the other systems, especially the microsystem.

Answers
Answer:
3 factors that influenced the food choice to be unhealthy and lead to a heart attack. I would guess how easy it is to get such unhealthy foods for cheap prices whenever they want. Lack of exercise and lastly not going to the doctor. Avoiding visiting your physician especially when the patient doesn't take action themselves to be healthier is not good. After having a heart attack Richard should avoid certain foods such as Bacon, sausage, and other processed meats. Potato chips and other processed packaged snacks, Dessert, Too much protein, Fast food, Energy drinks, Added salt, and even Coconut oil.

A patient has an IV solution running from one bag into a vein. Another bag is also attached through the same injection port, and it sends a secondary medication at a slower rate than the primary IV solution. Which route of administration injects two separate solutions through the same port on a patient like this?
A. bolus IV
B. IV infusion
C. IV piggyback
D. push IV
Answers
An IV piggyback delivers medication to the body through a small bag which can later be removed without changing the main IV. Thus, option C is correct.
What is IV infusion?The process of delivering medicines in the body through vein is referred as Intravenous (IV) infusion. It is a special way of injecting the medicines directly into the blood stream.
There are different ports through which the IV can be administered. It can be given by inserting a catheter in a vein, in the muscle or under the subcutaneous layer.
Thus, IV infusion delivers medication at a faster rate in the body.

How do social-cognitive theorists describe personality?
A set of stable traits since birth
Changeable in response to the environment
Changeable as a result of reflection, organization, and self-regulation
A result of biological processes
Answers
The social-cognitive theorists describe personality as changeable as a result of reflection, organization, and self-regulation. The correct option is C.
What are social-cognitive theories?According to the social cognitive theory, humans learn behavior through observational learning.
It states that, unlike some forms of learning, we do not require positive reinforcement (a reward) to maintain our behavior; we simply require the model to be rewarded/punished for behavior. This is referred to as vicarious reinforcement by Bandura.
The Social Cognitive Theory of Identity presumes that personality is shaped by interacting socioeconomic factors, cognitive factors, and behavior.
Thus, the correct option is C.

Instead of listing work experience, he should list his participation in extra-curricular activities, special skills he has, or volunteer experience. C. He should be really wordy when he describes what he has done. D. He will just have a really short resume.
Answers
Answer:
B. Instead of listing work experience, he should list his participation in extra-curricular activities, special skills he has, or volunteer experience.
Explanation:
When applying for a job, a person's resume says it all. Thus, it is important to know what details to include in the resume in order to have an edge over the other applicants.
Kurt should definitely not make-up his work experience. Lying about it will soon come out. This makes choice A incorrect.
Kurt shouldn't be wordy just to make his resume long. It should be kept simple, concise and clear (straight to the point). This makes choice C incorrect.
Kurt shouldn't settle for a very short resume. If he doesn't have that much work experience, he should focus on his achievements, skills and education which are relevant to the job he's applying for. This is often common to people who are just applying for their first job or are college graduates. This makes choice D incorrect and choice B correct.
