The blank spaces in the statement, “An increase in preload causes a/an _in stroke volume in accordance with the law. An increase in afterload causes a/an in stroke volume. An increase in contractility causes a/an in stroke.” Introduction: The stroke volume is the amount of blood pumped to the body parts during one heart beat. Contractility, preload, and afterload are the factors that describe the stroke volume. The extent to which the sarcomeres of the heart’s ventricular cells are stretched is called the preload. The intrinsic ability to pump the blood is determined by the contractility of the heart. The force that must be overcome by the right atrium and ventricles, in order to pump blood in their individual arteries is known as the afterload.

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?
