A client asks the nurse, "What is the purpose of measuring the level of oxygen in my child's blood?" Which response by the nurse is accurate?

Choice A rationale:

Measuring the level of oxygen in a child's blood does not help assess the electrical activity of the heart.

Oxygen measurement and the assessment of heart electrical activity are two separate concepts.

Choice B rationale:

Measuring oxygen levels in the blood primarily evaluates the child's oxygen saturation, not the respiratory rate and effort.

While oxygen saturation is related to respiratory function, it doesn't directly assess the rate and effort of breathing.

Choice C rationale:

Measuring the level of oxygen in a child's blood monitors oxygen saturation using pulse oximetry.

Pulse oximetry is a non-invasive method used to measure the percentage of oxygen saturation in the blood.

This is important because it provides information about the child's oxygen levels, which is crucial for assessing their respiratory and circulatory status.

Choice D rationale:

Measuring the level of oxygen in the blood does not measure the child's weight and developmental milestones.

This response is unrelated to the purpose of monitoring oxygen levels in the blood.

Choice A rationale:

"I've noticed a bluish discoloration of my skin and lips" is not a typical symptom of an atrial septal defect (ASD).

ASD is a congenital heart defect that involves an abnormal opening between the atria of the heart, and it typically results in increased blood flow to the lungs, not cyanosis.

Choice B rationale:

"I find it hard to feed, and I'm not gaining weight as expected" can be related to ASD, but it is not a primary symptom.

The increased blood flow to the lungs in ASD may lead to congestive heart failure, which can cause poor feeding and inadequate weight gain.

Choice C rationale:

"I feel short of breath and tired during physical activities" is a likely symptom of ASD.

With ASD, there is an increased volume of blood being pumped into the lungs, which can lead to pulmonary congestion, shortness of breath, and fatigue.

Choice D rationale:

"The doctor mentioned hearing unusual heart sounds during the examination" is not a symptom but rather a sign of an atrial septal defect.

Unusual heart sounds, like a fixed split second heart sound, may be heard on auscultation.
