Neurons are the building blocks of the nervous system and are responsible for transmitting information throughout the body. These cells require a constant supply of energy to carry out their functions. Glucose is the primary source of fuel for neurons, and it is the only nutrient that can cross the blood-brain barrier and enter the brain.

The reason why neurons rely so heavily on glucose is that they have a high energy demand. They need to maintain a resting potential, generate action potentials, and carry out synaptic transmission. These processes require a significant amount of energy, and glucose is the most efficient source of fuel for this purpose.

Additionally, neurons cannot store glucose like other cells in the body. They have a limited capacity to store glycogen, which is the storage form of glucose. Therefore, they need a constant supply of glucose to meet their energy needs.

Finally, glucose is essential for the synthesis of neurotransmitters, which are chemicals that transmit signals between neurons. Neurotransmitters are synthesized from various amino acids, and the process requires glucose as a precursor.

In conclusion, neurons rely heavily on glucose as their source of nutrition because it provides the energy needed to carry out their functions efficiently, it is the only nutrient that can cross the blood-brain barrier, and it is required for the synthesis of neurotransmitters.

The most common type of congenital heart defect that the nurse should assess for in infants is ventricular septal defect (VSD).

Ventricular septal defect (VSD) is the most common type of congenital heart defect, accounting for approximately 25% of all congenital heart defects. It occurs when there is a hole in the wall (septum) that separates the lower chambers (ventricles) of the heart.

This hole allows blood to flow between the ventricles, causing an abnormal circulation of blood in the heart. The severity of VSD can vary, ranging from small holes that may close on their own to larger defects that require medical intervention.

The nurse should assess for signs and symptoms of VSD in infants, such as difficulty feeding, poor weight gain, rapid breathing, and frequent respiratory infections. Additionally, the nurse may observe a murmur during auscultation of the heart.

The condition that is the progressive, long-term loss of lung function usually due to smoking is called chronic obstructive pulmonary disease (COPD).

COPD is a term used to describe a group of lung diseases that include chronic bronchitis and emphysema. It is primarily caused by long-term exposure to irritants, particularly cigarette smoke, although other factors such as environmental pollutants and genetic predisposition can also contribute. Smoking is the leading cause of COPD, and the majority of COPD cases are directly related to smoking.

Over time, smoking causes inflammation and damage to the airways and alveoli (air sacs) in the lungs. This leads to a progressive narrowing of the airways, increased mucus production, and destruction of lung tissue, which impairs airflow and makes it difficult to breathe. Symptoms of COPD include persistent coughing, wheezing, shortness of breath, and frequent respiratory infections.

COPD is a chronic and irreversible condition, meaning the lung damage is not fully reversible. However, early diagnosis, smoking cessation, and appropriate management can help slow down the progression of the disease, alleviate symptoms, and improve quality of life for individuals with COPD.

It is important to note that while smoking is the primary cause of COPD, not all smokers develop the condition, and nonsmokers can also develop COPD due to other risk factors such as long-term exposure to environmental pollutants or genetic factors.
