A client has suffered damage to his pericardium following a motor vehicle accident. Which consequence could be a possible complication of damaged pericardium that his care providers should assess for?
A) Impaired physical restraint of the left ventricle

D) Impaired regulation of myocardial contraction
Ans:
D
Feedback:
Regulation of myocardial contraction is not a role of the fibrous covering around the heart. The pericardium does restrain the left ventricle, reduce friction by way of fluid in the pericardial cavity, and provide a physical barrier to infection.
