Answer:

True

Explanation:

Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.

Each class of pacemaker cells has its own intrinsic rate.

For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).

The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).

<h3>What is diabetes?</h3>

The term "diabetes mellitus" describes a collection of illnesses that impact how the body utilizes blood sugar (glucose). The cells that comprise the muscles and tissues depend on glucose as a major source of energy. The brain uses it as its primary fuel source.

Diabetes has a variety of primary causes. However, diabetes can result in too much blood sugar, irrespective of the type you have. Serious health issues may result from an excessive blood sugar level.

<h3>What is glycemic index?</h3>

According to how much each food raises blood sugar, foods containing carbohydrates are given a number on the glycemic index. The glycemic index is a tool for assisting with meal selection and is not a standalone diet plan like calorie or carb tracking.

Greeley [361]

The assessment findings by the nurse which indicates that the patient with sickle cell disease is experiencing a liver complication is:

Creatinine: 2.9 mg/dL

The correct answer choice is option b.

<h3>How the rise in creatinine level result to liver problems</h3>

The rise in creatinine in the body usually, frequently and most of the time lowers homocysteine production in liver cells, when this happens, it exposes the liver to a dangerous health condition which occurs as a result of diminishing fat accumulation. When this happens, it damages the liver.

In conclusion, we can now confirm that an elevation in the creatinine levels causes health issues to the liver
