Appeared in: PGIMER NO - 2020

Explanation

After a pneumonectomy, positioning the patient on the operated side or supine is essential.
This position allows the remaining lung to expand fully, as it is not compressed by the body's weight or shifting organs.
It prevents a dangerous condition called mediastinal shift, where the heart and great vessels move into the empty chest cavity, which can compromise circulation and breathing.
This positioning also helps to contain fluid in the empty space and protect the bronchial stump.

Option A: While a High Fowler's position can help with general breathing, it does not specifically address the critical need to prevent mediastinal shift, which is the primary concern after a pneumonectomy. The lateral (side-lying) aspect of positioning is more important in this specific case.
Option B: This option is incomplete. While lying supine (on the back) is an acceptable position, it omits the other key position, which is lying on the operated side. The correct answer is more comprehensive.
Option D: This position is dangerous and strictly contraindicated. Lying on the un-operated side would place the patient's entire body weight on their only functioning lung, compressing it and leading to severe respiratory compromise and hypoxia.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Post-operative positioning following pneumonectomy as background academic context rather than a clinical decision trigger.
A nurse's primary responsibility is to ensure the patient is positioned correctly after a pneumonectomy to prevent life-threatening complications. This is a critical safety measure.
Nurses must frequently assess the patient's respiratory status, oxygen saturation, and for signs of mediastinal shift, such as tracheal deviation (away from the midline), sudden drop in blood pressure, and increased heart rate.
What if the patient had a lobectomy instead of a pneumonectomy? In that case, the patient would typically be positioned on the un-operated side ('good lung down') to promote drainage of the surgical site and enhance perfusion to the healthy lung tissue.

How to Approach the Question

First, identify the key procedure in the question: 'left pneumonectomy'. Understand that this means the entire left lung was removed.
Recall the primary goals of post-operative care after a pneumonectomy: 1) Maximize the function of the one remaining lung, and 2) Prevent complications like mediastinal shift.
Think logically about positioning. To allow the remaining (right) lung to expand, it must be free from pressure. Therefore, the patient cannot lie on their right side.
This leaves two options: lying on the back (supine) or lying on the operated (left) side. Both positions keep the right lung free to expand.
Evaluate the given options. 'Operated site and back' perfectly matches this conclusion.
Differentiate this from a lobectomy, where 'good lung down' (lying on the un-operated side) is often preferred. This is a common point of confusion tested in exams.

Concept Tested & Keywords

Concept Tested: Post-operative positioning following pneumonectomy.
Stem keywords: left pneumonectomy, position
Lead-in keywords: position given
Clinical cues: The procedure is a pneumonectomy, which involves the removal of an entire lung, making post-operative positioning critical to prevent life-threatening complications.
