Can stroke volume increase if edv does not change?
Bingel [31]

Answer:

The volume of a gas will decrease.

Let's think of some good examples. How about an air tank? Its volume is very small but the gas it contains could easily fill a small room. How is the volume so small, then? Because the gas is under extremely high pressure.

Okay so intuition from every day life tells us increase in pressure means decrease in volume.

Examples of temperature? A hot air balloon is filled by a flame that heats the gas inside it. The balloon gets bigger - the volume rises. This is an especially relevant example since the hot air balloon rises due to buoyancy, meaning the air inside it is less dense than the air outside it.

Less dense means there is less mass per volume inside it, so again we know that the gas inside the balloon has undergone an increase in volume in response to being heated.

So increase of temperature means an increase of volume.

The answer to your question, then, is that the volume will decrease (which is actually kinda difficult to do sometimes...but still a theoretical fact).

For further reading and understanding, see "Ideal gas law".

A 5 year old is seen in the urgent care clinic with the following history and symptoms: sudden onset of severe sore throat after
Lapatulllka [165]

Answer:

C. Acute Epiglottitis

Explanation:

Before explaining why C is the correct answer, let's look at why the others are <u>not</u> correct:

  • A. GABHS is a bacterial infection that is a type of streptococcus (aka Strep). It is also the most common cause of Tonsillitis! Symptoms of GABHS typically include: Sore Throat, fever, swollen lymph nodes, and  tonsillar exudates. It sounds very like what we're looking for, but notice drooling isn't a symptom found with this one!
  • B. Acute Tracheitis is inflammation of the trachea often resulting from a bacterial infection. Symptoms of this condition are more breathing-related such as severe dry cough, wheezing, and even shortness of breath and cyanosis. Not what we're looking at.
  • D. Acute Laryngotracheobronchitis is a common disease found in young children that is more commonly known as Croup. This disease is most often characterized by a "barking cough." Other symptoms include fever, stridor and hoarseness.

Now, WHY is C the correct answer?:

Acute Epiglottitis is, like croup, commonly found in younger children and is defined as inflammation of the epiglottis (the flap that covers the trachea when swallowing). It is often characterized by fever, sore throat, difficulty swallowing, and (more specifically) drooling! The drooling coupled with the clear bilateral breath sounds and absence of a cough help to diagnose this illness.
