A nurse plans care for the patient with increased intracranial pressure with the knowledge that the best way to position the patient is to
maintain patient in Trendelenburg position
use a continuous-rotation bed to continuously change patient position
elevate the head of the bed to 30 degrees
keep the head of the bed flat
The Correct Answer is C
A. Trendelenburg position (head lower than feet) can increase intracranial pressure and is contraindicated.
B. Continuous rotation may increase ICP due to frequent position changes and is generally avoided.
C. Elevating the head of the bed to 30 degrees promotes venous drainage from the brain, helping reduce intracranial pressure while maintaining cerebral perfusion.
D. Keeping the head flat can impair venous drainage and increase ICP.

Correct Answer is C
Explanation
A. It enlarges the heart chambers – This is typically seen with volume overload, not pressure overload. Volume overload leads to chamber dilation, not wall thickening.
B. It strengthens heart valves – Afterload does not improve valve function; in fact, high afterload can worsen conditions like aortic stenosis over time.
C. It thickens heart walls – The heart compensates for increased afterload (e.g., from chronic hypertension or aortic stenosis) by hypertrophying (thickening) the ventricular walls. This is called concentric hypertrophy, a structural adaptation to increased pressure.
D. It thins the heart walls – Thinning occurs in conditions like dilated cardiomyopathy where the problem is decreased contractility and volume overload, not increased afterload.
Correct Answer is A
Explanation
A. Cor pulmonale causes right-sided heart failure, leading to systemic venous congestion and dependent edema.
B. Chest pain is more commonly associated with left-sided heart issues or coronary artery disease.
C. Crackles in the lungs are signs of left-sided heart failure due to pulmonary congestion.
D. Hypotension is not a typical early sign of cor pulmonale or right-sided heart failure.
