Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
How does urine go into the lungs?
The only way urine could possibly ever get into the lungs would be if the person inhaled or drank urine. Not a good thing to do.
Can tattoo ink show up in urine?
Not likely. Tattoo ink may be removed from the blood, but it would appear in trace amounts in urine.
Why would a heart bypass operation be cancelled if the patient's Trop T is found to be high- and can bypass still be done later?
An increased Trop-T can indicate myocardial damage. They would not want to perform surgery on an already damaged heart. - Hence they probably want to wait. It is possible for it to be done later, however it depends on recovery.
Does cardiac output affect urine output?
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
If a patient who has had major abdominal surgery receives intravenous fluids equal to the blood volume lost during surgery would you expect urine volume to be greater or less than normal?
I would expect the urine output to tail off for a few hours due to the stress on the kidneys and the time it takes for the body to respond to the fluid.
Would glucose in urine increase output or decrease it?
increases
Would an increase in contractility cause an increase to cardiac output?
Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.
An excessive urine output is called anuria?
A normal urine output for adults would be about 100ml/hour; beyond 125ml/hour would be considered excessive if it extended for more than 1-2 days.
What would the color of urine be if you have kidney infection?
The colour of urine in diabetes (both, diabetes mellitus and diabetes insipidus) is very very pale yellow (almost colourless). This is because diabetes is characterised by polyuria ie, increased volume of urine output, which is majorly due to increased excretion of water from the body, the quantity of pigment urochrome (which gives the normal pale yellow colour to urine) remaining the same. This makes urine in diabetic patients more pale, almost colourless
What is wrong with me if I have increased urine output a high temperature with no appetite and my vomit is reddish black in color?
This list is not pathognomomic, but I would suggest talking to your physician. Increased urine output can be due to drinking increased amounts of water, and running a fever while having little appetite can be due to an influenza infection. However, vomiting red-black material indicates you have blood in your stomach - this is much more serious than a simple viral infection. You should see a physician as soon as possible, preferrably within the next 24 hours.
What would happen to urine pH if you increased secretion of hydrogen?
it would become more acidic
Which of the following would cause the greatest increase in cardiac output?
Increased heart rate and increased stroke volume
What is Urinary output?
A normal urine output for adults would be about 100ml/hour; beyond 125ml/hour would be considered excessive if it extended for more than 1-2 days.
Bladder opened during surgery and urine spills into the wound should surgery team have concerns?
Probably not. Urine is sterile unless there is an infection. The surgeon would likely suction the area, and pack it with gauze until it was time to close.
If a patient who has had major abdominal surgery receives intravenous fluids equal to the blood volume lost during surgery would you expect urine volume to be greater or less than why?
the patients normal urine amount, because all you're doing is replacing fluid lost.
