Answer:
Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Explanation:
Inotropism is a health science term to refer to the contraction capacity of the cardiac (myocardial) muscles. Inotropic action influences contractile force, velocity of myocardial pressure development and ejection velocity.
- Negative inotropic effect means contraction force decreases or decreases cardiac output
- Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Positive chronotropic action increases
- heart rate -
tachycardia;
- cardiac contraction force, both atrio and ventricles);
- conduction velocity in the atrioventricular node.
I think it’s B hope this helps sorry if I’m wrong
Answer: The rigth answer is: A. Severe swelling and redness at a midshaft femur
Explanation: There are some contraindications for the use of a traction splint among them are: -Injuries near the knee and injuries of the hips and / or pelvis and amputation of some part of the limb, therefore option B and D are incorrect. The traction splint firmly grabs the ankle, if there is an injury that interferes with the hitch, it cannot be placed, so option C is incorrect. If there is a femur fracture, it is very common to find severe swelling and redness in the femur of the middle axis and there is no problem with placing the traction splint because the purpose of this is to stabilize the fracture.
B. When the environment is damaged, our health improves
