Baby Ravi is undergoing phototherapy treatment for hyperbilirubinemia. Which parts of his body should be covered to prevent tissue damage?

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2015

Explanation

The primary goal of phototherapy is to expose the maximum possible skin surface area to light for effective bilirubin breakdown.
The intense light used in phototherapy can cause retinal damage, making protective eye shields mandatory.
The gonads (genitalia) are also shielded as a precaution against potential tissue damage, which is typically accomplished by leaving a small diaper on the infant.
Covering both the eyes and genitalia balances treatment efficacy with essential safety precautions.

Option A: Covering the abdomen is incorrect because it significantly reduces the skin surface area exposed to the light, thereby decreasing the effectiveness of the phototherapy.
Option C: Covering the extremities (arms and legs) is incorrect as it drastically reduces the available skin surface area for treatment, making the phototherapy less efficient.
Option D: This option is incorrect because it fails to protect the infant's eyes, which are highly susceptible to retinal damage from the high-intensity light.

Clinical Relevance

Nursing practice connection: Knowing Safety precautions during neonatal phototherapy helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a crucial role in managing phototherapy, including ensuring proper shielding of eyes and genitalia, maximizing skin exposure, and monitoring for potential side effects.
Key nursing responsibilities include monitoring the infant's temperature to prevent hypo/hyperthermia, assessing hydration status due to increased insensible water loss, and repositioning the infant every 2 hours.
What if? If the infant's temperature becomes unstable (e.g., drops below 36.5°C or rises above 37.5°C), the nurse should first re-check the thermostat of the incubator or radiant warmer and the infant's position relative to the light, and then notify the physician, as the therapy may need to be temporarily paused or adjusted.

How to Approach the Question

First, identify the core concept of the question, which is the safety protocol for phototherapy in newborns.
Recall the primary goal of phototherapy: to expose as much skin as possible to light to break down bilirubin.
Next, consider the principle of minimizing risk. Think about which parts of a newborn's body are most sensitive to high-intensity light.
The eyes (retina) and reproductive organs (gonads) are known to be sensitive and require protection.
Therefore, the correct procedure must involve covering these sensitive areas while leaving the rest of the body (trunk, limbs) exposed.
Evaluate the given options: Only 'Eyes and Genitalia' aligns with this principle of maximizing exposure while protecting sensitive tissues.
