Does friction enhance movement? True or false
Answer:
False. Friction does not enhance movement.
Friction is the force that is generated when two objects "rub" on each other.
For example, it's hard to push an object on a rug, but it's easier to push an object on hardwood floor. This is because the rug creates more friction when the object rubs against it, thus slowing it down.
So, the statement is false.
Hope this helps.
Answer: False
Explanation:
Friction always in opposite direction to movement

This question is incomplete because the options are missing; here is the complete question:
A co-worker was sanding an object on a belt sander when he slipped. He has an abrasion on his elbow that is about 3 inches long 2 inches wide. The wound bled a little at first but has stopped. What type of bleeding is this most likely to be?
A. Capillary
B. Venous
C. Arterial
D. Both venous and arterial
The answer to this question is A. Capillary
Explanation:
Capillary bleeding is the least serious bleeding, this occurs in superficial wounds including abrasions, and in most cases, this type of bleed will stop after some minutes without any intervention. Moreover, this bleeding is caused due to the damage of capillaries, which are very small blood vessels.
Capillary bleeding is most likely the bleeding in the co-worker because the injury was mainly superficial and the bleeding stop after some minutes. Also, the blood loss was minimal, which occurs in capillary bleeding but not in arterial or venous bleeding.

1. You have received a physician's order to administer 1 mg of a medication to a patient. It is a medication that is injected into the muscle. As soon as you have given the medication, you realize
you measured 1 mL instead of calculating 1 mg. What would you do?
Answer:
Check the prescription on the bottle, monitor the patient for s/s of adverse reactions, monitor site, check vitals, call the doctor and inform them of the medication error
Explanation:
1 mL of medication can be 10 mg of the medication, hence you've overdosed the patient. 1 mL of medication can also be 1 mg of the medication. It depends on the concentration. ex. the medication can read 10mg/1mL, in this case you would give 0.1 mL

A home health nurse who sees a client with diverticulitis is evaluating teaching about dietary modifications necessary to prevent future episodes. Which statement by the client indicates effective teaching
Answer:
"I should increase my intake of fresh fruits and vegetables during remission"
Explanation:
Diverticulitis is an inflammation or infection in one or more small pouches in the digestive tract. After the nurses' teachings a statement that would indicate this would be "I should increase my intake of fresh fruits and vegetables during remission". This is because, even though doctors say that patients with diverticulitis should avoid high fiber diets, when in remission eating lots of fresh fruits and vegetables is known to prevent acute diverticulitis.
Which is the correct path of an electrical excitation from the pacemaker to a cardiomyocyte in the left ventricle (LV)?
Answer:
The question is lacking the options, below is the completely stated question and options:
This is the correct path of an electrical excitation from the pacemaker to a cardiocyte in the left ventricle (LV).
A. sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
B. atrioventricular (AV) node → sinoatrial (SA) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV
C. sinoatrial (SA) node → atrioventricular (AV) bundle → atrioventricular (AV) node → Purkinje fibers → cardiocyte in LV
D. atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → sinoatrial (SA) node → cardiocyte in LV
E. sinoatrial (SA) node → atrioventricular (AV) node → Purkinje fibers → atrioventricular (AV) bundle → cardiocyte in LV
Answer:
The correct answer is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Purkinje fibers → cardiocyte in LV (A.)
Explanation:
The electrical impulse conduction system of the heart refers to the pathways through which electrical signals pass, to cause excitation of specific paths of the heart, leading to depolarization, which in turn leads to contraction and relaxation of the heart. The correct excitation pathway is as follows:
1. Normal excitation originates in the sinoatrial (SA) node, from which depolarization spreads throughout the atria, causing impulses (excitation) to spread from the SA node to the atria. It is believed that this depolarization spreads to the atrial cells through adjacent myocardial cells and myofibrils.
2. Next, the depolarization from the atria reaches the atrioventricular (AV) node, causing excitation of the AV node. The AV node is located on the floor of the right ventricle, close to the interventricular septum. The excitation leaves this site by two pathways; the fast and slow pathways which vary based on the time of transmission of impulses to the next phase.
3. Next, from the AV node, the excitation is passed to the two branches of the bundle of His, which form a network of fibers known as purkinje fibers, from where excitation passes to the apical region of the left and right ventricles causing depolarization of the ventricular myocardium.
Attached to this answer is a picture to show what the pathway looks like.
The correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.
The heart is a cone-shaped hollow muscular organ that possesses the property of generating its own electrical impulses or excitations.
It is divided into four(4) chambers namely the right ventricle, left ventricle, right atrium and left atrium.
The correct path of an electrical excitation is from:
The pacemaker: This is also called the sinoatrial (SA) node. It generates the electrical excitations.Atrioventricular (AV) node: The electrical excitation initiated by SA node is then transmitted to AV node. This transmits the signal from atria to ventricles.Atrioventricular (AV) bundle: These are specialised fibres that originate from the AV node. They are the bundle that divides to form the right and left bundle branches.Subendothelial conducting network: This is also called the Purkinje fibres which is formed within the ventricular myocardium.Cardiomyocyte of the left ventricle: The cardiomyocytes are set of cells that generates contractile force in the heart. These are located at the left ventricle.Therefore, the correct path of an electrical excitation from the pacemaker to a cardiomyocyte is:
sinoatrial (SA) node → atrioventricular (AV) node → atrioventricular (AV) bundle → Subendothelial conducting network → cardiomyocyte in LV.

g what constitutes a healthy or normal bmi? what are some of the reasons it is useful to have a single number, such as a bmi, to describe a height/weight relationship? what are the drawbacks?
Answer:
BMI is the shortened form for Body Mass Index.
The Body Mass Index is a simple arithmetic for determining one's body fat using their height and weight.
The formula is given as
[tex]\frac{Weight (Kilograms)}{Height (Metres)}[/tex] or
[tex](\frac{Weight (Pounds)}{Height (Inches}) * 703[/tex]
If an adults BMI falls within the 18.5 to 24.9 range, it is considered healthy.
One of the benefits of using BMI as a health metric is that it is so easy to compute.
Its major disadvantage is that it only accounts for height and weight which can be altered by a variety of circumstances and as such in most cases are not the best indicators of whether or not, one if healthy.
For example, a higher muscle mass will mean more weight and as such, a higher BMI. Generally speaking, more muscle and less fat is healthy. So BMI, in this case, is useless as a metric of health status.
Other factors which alter the reading of BMI are: Gender, Frame Size, Age,
Pregnancy etc.
An individual who is very muscular, pregnant, or have a large frame, will most likely have a higher BMI calculation which may indicate that one is obese or overweight when they're not.
