Hypovolemic shock resulting from burns is usually caused by:

Medicine
1 answer:
Viktor [21]3 years ago
5 0

Answer: Option A "Loss of body fluids"

Explanation:

When the body lose blood or other fluids from the body, then the amount of blood in the body is reduced. The Hypovolemic shock happens when a sudden loss of body fluids takes place which is extremely dangerous.

Example:

At the time of delivery, there is blood loss from the body. At the time of injury there is a loss of blood from the body. These processes leads to loss of blood and body fluids.

In case of extensive burns leads to loss of body fluids.

Hence, the correct answer is option A.

The external auditory canal is a cul-de-sac 2.5 to 3 cm long in the adult and terminates at the:_____.
Reika [66]

The External auditory canal is a cul-de-sac 2.5 to 3 cm long in the adult and terminates at the <u>Tympanic membrane.</u>

<u></u>

<u></u>

The External auditory canal is an S- shaped Osseo-cartilaginous structure that extends from the auricle to the tympanic membrane. Congenital, inflammatory, neoplastic, and traumatic lesions can affect the external auditory canal. The main function of the External auditory canal is to conduct sound waves in the form of vibrations to the tympanic membrane. The most common congenital lesion affecting the External auditory canal is atresia.

When looking at postural alignment from a posterior view, the vertical line should pass through the ________
Nonamiya [84]

When looking at postural alignment from a posterior view, the vertical line should pass through the midline of the body.

<h3>What is Postural alignment?</h3>

Postural alignment may be defined as the final outcome of the way through which the body has been utilized over a prolonged period of time. this alignment completely influences the movement, stability, balancing, strength, flexibility, etc. of the body.

The ideal postural alignment may be defined as when your head should be above your shoulders, and the top of your shoulder should be over the hips.

The postural alignment may be seen from different views which reveal a different outcome.

Therefore, when looking at postural alignment from a posterior view, the vertical line should pass through the midline of the body.

One option for cancer treatment is removal of the ____________ , especially if detected at an early stage.
GalinKa [24]

Answer: tumor

Explanation:

- Tumors, which are lumps of tissue occur when cells divide and grow excessively in the body. Tumors can be cancerous or not cancerous (benign). Cancerous tumors spread into, or invade, nearby tissues and can travel to distant places in the body to form new tumors.

- If possible, an option for cancer treatment is removal of the tumor which is fueling the cancer. The idea is that when you take out the source, everything else will clear up and you should ultimately be cancer free. Although it is one of the best options, it is not always successful.

hope this helps :)

Be able to describe the cardiac cycle using the appropriate chambers, valves, and vessels. What are the stages of the cardiac cy
Natasha_Volkova [10]

Answer:

The heart beat sequence is the sequence of events that occurs when the heart beats. As the heart beats, blood circulates through the pulmonary and systemic circuits of the body. There are two stages of the heart beat cycle: the diastole phase and the systole phase. In the diastole phase, the ventricles of the heart relax and the heart fills with blood. In the systole phase, the ventricles contract and pump blood from the heart to the arteries. A cardiac cycle is completed when the chambers of the heart fill with blood and blood from the heart is pumped.

Explanation:

1. Ventricular Diastole

For the period of ventricular diastole, the atria and ventricles of the heart are relaxed and the atrioventricular valves are open. The oxygen-free blood that returns to the heart from the body after the last cardiac cycle passes through the superior and inferior cava veins and flows into the right atrium.

Open atrioventricular valves (tricuspid and mitral) allow blood to pass through the atria into the ventricles. The impulses of the sinoatrial node (SA) travel to the atrioventricular node (AV) and the AV node sends a signal that triggers the contraction of both atria. As per a result of this reduction, the right atrium empties its contents into the right ventricle. The tricuspid valve, located between the right atrium and the right ventricle, prevents blood from flowing into the right atrium.

2. Ventricular Systole

At the beginning of the ventricular systole period, the right ventricle, which is full of blood that passes from the right atrium, receives impulses from the fiber branches (Purkinje fibers) that carry electrical impulses that cause it to contract. When this occurs, the atrioventricular valves close and the semilunar valves (pulmonary and aortic valves) open.

Ventricular contraction causes oxygen depleted blood from the right ventricle to be pumped into the pulmonary artery. The pulmonary valve prevents blood from returning to the right ventricle. The pulmonary artery carries deoxygenated blood along the pulmonary circuit to the lungs. Here, the plasma gathers oxygen and returns to the left atrium of the heart through the pulmonary veins.

3. Atrial Diastole

In the period of atrial diastole, semilunar valves close and atrioventricular valves open. Oxygenated blood from the pulmonary veins fills the left atrium, while blood from the vena cava fills the right atrium. The SA node contracts again, causing both atria to do the same.

in the next step of process, atrial contraction causes the left atrium to empty its contents into the left ventricle and the right atrium to empty its contents into the right ventricle. The mitral valve, located between the left atrium and the left ventricle, prevents oxygenated blood from returning to the left atrium.

4. Atrial Systole

During the period of atrial systole, the atrioventricular valves close and the semilunar valves open. The ventricles receive impulses to contract. Oxygenated blood in the left ventricle is pumped into the aorta and the aortic valve prevents oxygenated blood from returning to the left ventricle. The oxygen-depleted blood is also pumped from the right ventricle to the pulmonary artery at this time.

The aorta branches to provide oxygenated blood to all parts of the body through systemic circulation. After its journey through the body, deoxygenated blood returns to the heart through the vena cava.

How to calculate the heart rate from the electrocardiogram ?​
Masja [62]

Answer:

ECG paper is a grid where time is measured along the horizontal axis.

Each small square is 1 mm in length and represents 0.04 seconds.

Each larger square is 5 mm in length and represents 0.2 seconds.

Voltage is measured along the vertical axis.

10 mm is equal to 1mV in voltage.

The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form

Heart rate can be easily calculated from the ECG strip:

When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.

For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).

The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.

For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
