Verified step by step guidance

Understand the condition: Right lower lobe pneumonia affects the right lung, specifically the lower lobe, causing inflammation and fluid accumulation that can impair lung function.

Consider gravity's role: Positioning can help drain secretions and improve ventilation. Gravity can assist in clearing the affected area by promoting drainage from the right lower lobe.

Evaluate the options: Positioning the child on their left side may help improve ventilation and drainage of the right lower lobe by allowing gravity to assist in clearing secretions.

Assess the benefits of upright positioning: Sitting upright can enhance lung expansion and facilitate breathing, but may not specifically target the drainage of the right lower lobe.

Determine the least effective positions: Lying on the back or right side may not optimize lung function for the affected right lower lobe, as these positions do not promote effective drainage or ventilation.
