Answer:

C) substitutions that reduce the affinity of hemoglobin for oxygen

Explanation:

Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.

The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.

<h3>What does "recommended dietary allowance" refer to?</h3>

The Food and Nutrition Board has determined the levels of essential nutrient intake known as Recommended Dietary Allowances (RDAs) to be sufficient to meet the known nutrient needs of nearly all healthy individuals.

For those unable to excrete nitrogenous wastes, such as those with severe liver disease or renal failure, protein restriction is employed.

The recommended dietary allowance is 0.8 grams per kilogram of body weight for an average inactive adult.

Tema [17]

Answer:

Atropine is highly potent antagonist of G-Class proteins of receptors termed as muscarinic acetylcholine receptors. Atropine blocks the action of these receptors and suppress the effects caused by parasympathetic nervous system. These complications of Atropine may lead to Tachycardia in patients administrated with atropine.

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
