Correct Answer is A
Explanation
Choice A Reason: This is correct because using log rolling to reposition the client helps maintain the alignment of the head and neck, which prevents further increases in ICP.
Choice B Reason: This is incorrect because placing a warming blanket on the client can cause vasodilation and increase cerebral blood flow, which can raise ICP.
Choice C Reason: This is incorrect because instructing the client to cough and deep breathe can increase intrathoracic pressure and impede venous return, which can elevate ICP.
Choice D Reason: This is incorrect because placing the client in a supine position can decrease cerebral perfusion pressure and increase ICP. The client should be placed in a semi-Fowler's position with the head elevated at 30 degrees.
Correct Answer is C
Explanation
Choice A Reason: This is incorrect because right ventricular failure would cause an increase in right atrial pressure and right ventricular end-diastolic pressure, but not in PAWP, which reflects left atrial pressure and left ventricular end- diastolic pressure.
Choice B Reason: This is incorrect because fluid volume deficit would cause a decrease in PAWP, as there would be less blood volume in the pulmonary circulation.
Choice C Reason: This is correct because mitral regurgitation would cause an increase in PAWP, as the blood would back up into the left atrium and pulmonary veins due to the incompetent mitral valve.
Choice D Reason: This is incorrect because afterload reduction would cause a decrease in PAWP, as there would be less resistance to the left ventricular ejection and less blood volume in the pulmonary circulation.
