Homework Answers
26. C) prevent the heart from expanding and filling properly, therefore restrict the ability of the heart to pump blood
27.a) ventricular contractions
Since ventricular contraction is important for the transport of blood to organs and lung but not the return of blood to atrium
28. D) internal jugular veins
Jugualr vein collects blood from brain and face and deliver to heart
29.a) atriventrucular valve closes
The first s1 sound is due to closure of atrioventricular valve since ventricular pressure exceed atrial pressure
30.b) oxygenated , heart
Pulmonary veins carries oxygenated blood from the lung and deliver to heart
31.b) ventricular repolarization which corresponds with relaxation of ventricular synctyium

What is caused by an accumulation of blood in the pericardial space that results in impaired systemic venous return, impaired ventricular filling, and reduced cardiac output? Tension pneumothorax Ductal-dependent congenital heart lesions Massive pulmonary embolism Cardiac tamponade If bradycardia (heart rate less than 60 beats per minute) with a pulse is associated with cardiopulmonary compromise despite effective oxygenation and ventilation, what is the next step in management? Administer atropine. Administer epinephrine. Consider cardiac pacing. Perform CPR. The first energy dose...

Epinephrine causes muscles to contract and the heart and lungs to increase respiration and blood flow. In combination with epinephrine causing glucose production and secretion from the liver, how does epinephrine elicit a system wide response? Multiple Choice A.) Glucose provides energy for muscle contractions, which are stimulate by high concentrations of oxygen. Oxygen is provided by the increase in respiration and blood flow. B.) Glucose provides energy for muscle contractions, resulting in high levels of pyruvic acid. The pyruvic...
