A nurse wants to become part of a Disaster Medical Assistance Team (DMAT) but is concerned about maintaining licensure in several different states. What statement by the nursing supervisor best addresses these concerns?
Answer: a. "Deployed DMAT providers are federal employees, so their licenses are good in all 50 states."
Explanation:
Disaster Medical Assistance Teams are teams consisting of professionals and para-professionals in the medical profession who are called upon during matters of National Emergency when medical personnel are needed to respond rapidly to save lives. They therefore deal with events such as terrorist attacks, natural or man-made disasters, disease outbreaks and the like.
They fall under the National Disaster Medical System which operates at a Federal level.

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.

According to the escience lab manual for lab 1, experiment 3, you need to prepare a 47 mL of a 24% soda/syrup prescription. To do this, you can use the 80% syrup solution and the 10% soda solution that you have in stock. How many mLs of soda solution do you need to create this final solution?
Answer:
33 mL
Explanation:
It is important to recognize that the total amount of pure syrup remains constant:
Total syrup in the stock solution = total syrup in dilute solution
Thus, we can use the dilution formula
V₁c₁ = V₂ c₂
Data:
V₁ = ?; c₁ = 80 %
V₂ = 47 mL; c₂ = 24 %
Calculations:
1. The volume of stock syrup
[tex]\begin{array}{rcl}V_{1}c_{1} & = & V_{2}c_{2}\\V_{1}\times80 \, \% & = & \text{47 mL}\times 24 \, \%\\80V_{1} & = & \text{1130 mL}\\V_{2}&=& \dfrac{\text{1130 mL}}{80}\\\\&=&\text{14 mL}\\\end{array}\\\text{You need $\textbf{14 mL}$ of stock syrup.}[/tex]
2. The volume of soda solution
Total volume of dilute solution = 47 mL
The volume of stock syrup = 14
Volume of soda solution = 33 mL
You need 33 mL of soda solution.
For how long should most adults in moderately good physical condition and with healthy lungs be able to hold their breath
Answer:
30 seconds and up to 2 minutes
Explanation:
Most adults should be able to hold their breath for between 30 and 1 minute if they are in relatively excellent physical condition and have healthy lungs. However, this can change depending on things like age, fitness level and general health.
What is Health?The concept of health is comprehensive and includes a state of mind, body and social relations of an individual. Physical fitness is the state of a person's body and their ability to engage in physical activity without experiencing excessive fatigue or physical restrictions. Regular exercise, proper diet, getting enough sleep and avoiding bad habits like smoking and excessive drinking are all necessary to maintain excellent physical health.
Maintaining healthy lungs is important for maintaining physical health in terms of lung health. The lungs are affected by many variables including smoking, air pollution and respiratory diseases. They are in charge of supplying oxygen to the body and eliminating carbon dioxide. Regular exercise can help increase lung capacity and function.
Therefore, most adults should be able to hold their breath for between 30 and 1 minute if they are in relatively excellent physical condition and have healthy lungs.

1. Asthma is a restrictive lung disorder that causes constriction and congestion of the pulmonary bronchioles. How would an asthma attack affect FVC
Answer:
by hyperinflation of lungs
Explanation:
Asthma is a disease of the lungs caused by inflammation and narrowing of the airways, thereby difficulting breath. Severe asthma disorders are associated with a significant decrease in the rate of maximal expiratory airflow and the reduction in the total volume expired, which is a value known as Forced Vital Capacity (FVC). In consequence, severe asthma events are correlated with the hyperinflation of the lungs and thus be a possible cause for the observed reduction in the FVC.

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.
