are the patient's dyspnea, pallor and elevated resting heart rate related to the presence of blood in the stool? What lab test might be ordered to assess this possibility?
Homework Answers
The patient's dyspnea, pallor, and elevated resting heart can be related to the presence of blood in the stool in case the patient is suffering from diseases such as; pheochromocytoma a rare, noncancerous (benign) tumor that usually develops in an adrenal gland, (MayoClinic). The various lab tests that might be ordered to assess this possibility include biochemical tests to measure the levels of catecholamines i.e. the adrenaline, noradrenaline, and dopamine and metanephrines.

(a) A person's "resting" heart rate is his or her normal heart rate measured while sitting still (and long after doing anything physically exerting). A nurse on Earth measures the resting heart rate of a patient as 66.0 beats/min. Imagine the patient travels aboard a spaceship moving with a constant speed of 0.89c with respect to the Earth. What would be the patient's resting heart rate (in beats/min) as measured by someone else aboard the ship? beats/min (b) Imagine an...

The left ventricle of a resting adult’s heart pumps blood at a flow rate of 83 cm3/s, and an average heartbeat increases the pressure in the vessels by 79.5 mm Hg, the speed of the blood from zero to 25 cm/s, and the height by 11.6 cm. a. Calculate the total power output of the left ventricle in W. Note that most of the power is used to increase blood pressure, and the density of blood is about 1050 kg/m3.

The left ventricle of a resting adult's heart pumps blood at a flow rate of 87.0 cm3/s, increasing its pressure by 110 mm Hg, its velocity from zero to 25.0 cm/s, and its height by 5.00 cm. (All numbers are averaged over the entire heartbeat.) Calculate the total power output (in W) of the left ventricle. Note that most of the power is used to increase blood pressure

At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body On average, what mass of blood does the heart pump with each heart beat? kg mass per heart...

A 35-year old male with headache, fatigue, light-headedness, dyspnea (difficulty in breathing), and tachycardia (rapid heart rate). Laboratory findings reveal anemia, presence of red blood cell spherocytes, and a positive direct Coomb's test (presence of auto-antibodies on red blood cell surfaces). The patient is currently taking an antibiotic for symptoms of upper respiratory infection. These findings suggest that the antibiotics may have triggered an autoimmune disease which can also be classified as which type of hypersensitivity disease? a. Type II...
