The nurse working on a cardiac care unit is caring for a patient whose stroke volume has increased. The nurse is aware that afterload influences a patient's stroke volume. The nurse recognizes that afterload is increased when which is present?
a. sepsis
b. venous congestion
c. arterial vasodilation
d. hypertension
Answer:
(√) d. hypertension
Explanation: 1. Above mentioned option is right related to increased afterload because increase in blood pressure causes hard work for left ventrical to eject blood into the aorta which leads to increased afterload.
2. It is just because aortic valve needs more pressure to open in order to allow blood flow into ventrical.
Other options explanation:
a. Sepsis: 1. It is a wrong option because sepsis is caused by infection which leads to impaired heart functioning that causes low blood pressure.
2. Low blood pressure leads to decrease in afterload.
b. Venous congestion: 1. It is also a incorrect option because venous congestion causes lack of blood flow to heart that leads to heart failure.
c. Arterial vasodilation: 1. It is also not a correct option because arterial vasodilation causes dilation of the arteries which leads to low blood pressure that means decreased afterload.
