Q: Which of the following equations correctly defines pulse pressure?

$$\text{Pulse Pressure} = \text{Systolic Pressure} - \text{Diastolic Pressure}$$

Q: If end diastolic volume (EDV) is 120 mL and end systolic volume (ESV) is 50 mL, what is the stroke volume?

$$\text{Stroke Volume} = 120\,\text{mL} - 50\,\text{mL} = 70\,\text{mL}$$

Question 1

A patient is given an injection of erythropoietin (EPO) after suffering from chronic kidney disease. Which of the following changes would you expect to observe in their blood test results two weeks later?

Accepted Answer

Increased hematocrit due to enhanced erythrocyte production

Question 2

Which of the following best explains why the left ventricular wall is thicker than the right ventricular wall?

Accepted Answer

It pumps blood with greater pressure to the systemic circulation

Question 3

A patient with type B blood receives a transfusion of AB blood. What is the most likely immediate consequence?

Accepted Answer

The patient’s anti-A antibodies will agglutinate with A antigens in the donor blood

Question 4

Which of the following equations correctly defines pulse pressure?

Accepted Answer

$$	ext{Pulse Pressure} = 	ext{Systolic Pressure} - 	ext{Diastolic Pressure}$$

Question 5

If end diastolic volume (EDV) is 120 mL and end systolic volume (ESV) is 50 mL, what is the stroke volume?

Accepted Answer

$$	ext{Stroke Volume} = 120\,	ext{mL} - 50\,	ext{mL} = 70\,	ext{mL}$$
