A lacrosse player has received a severe blow to the quadriceps by an opponent's knee. there is marked pain and swelling, and the

Vesnalui [34]

This patient has a soft tissue contusion involving the quadriceps muscle. In acute care setting, the patient should be advised rest, ice, compression, and elevation or RICE. Might as well, an x-ray should be done to rule out potential fractures and dislocations. Possibly, casting may be done. Medications like pain relievers may be given to soothe the pain. Upon follow-up, range of motion should be assessed and repeat x-ray may be done. Removal of casts may be done also. Continue RICE.

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an

mixas84 [53]

Answer:

Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers. When coupled with a 10x (most common) eyepiece lens, we get total magnification of 40x (4x times 10x), 100x, 400x, and 1000x. To have good resolution at 1000x, you will need a relatively sophisticated microscope with an Abbe condenser. The shortest lens is the lowest power, the longest one is the lens with the greatest power. Lenses are color coded and if built to DIN standards are interchangeable between microscopes. The high power objective lenses are retractable (ie 40xr). This means that if they hit a slide, the end of the lens will push in (spring loaded) thereby protecting the lens and the slide. All quality microscopes have achromatic, parcentered, parfocal lenses.

Cousteau and Gagnan:

Leviafan [203]

Answer:

The answer is A. Invented SCUBA

Explanation:

Emile Gagnan and Jacques Cousteau were engineers who invented the first SCUBA device, the Aqua-Lung.
Gagnan's most important contribution to this discovery was his theory that a valve commonly used in gas generator engines would be useful in regulating air supply under water in varying pressures.

if an action potential could not be received by the atrioventricular node, despite the propagation through sinoatrial node, what

Fofino [41]

You would predict this to occur as an opening of atrioventricular valves, atria contraction, and filling of ventricles with blood if an action potential could not be received by the atrioventricular node, despite the propagation through the sinoatrial node.

So, the correct options are B, C &E.

It enables a left atrium action potential, causing both atria to contract simultaneously before the ventricles do. The AV delay delays the contraction of the ventricles by slowing the rate at which the impulse reaches them. This is significant because it gives the atria enough time to finish contracting so that the greatest amount of blood may be discharged into the ventricles.

The right and left atria to have time to contract first (eject blood to the ventricles) before the ventricles contract, which is why the AV node delay is so crucial. The AV node is a modified myocardium.
