A client reports being unhappy with their body weight. On assessment, the nurse notes tooth decay, an inflamed throat, gastroesophageal reflux disorder, and dehydration. The nurse knows these findings are consistent with which disorder?
Night eating syndrome
Anorexia nervosa
Binge-eating disorder
Bulimia nervosa
The Correct Answer is D
A. Night eating syndrome involves consuming large amounts of food at night, often leading to weight gain, but it is not typically associated with tooth decay, inflamed throat, or gastroesophageal reflux caused by purging behaviors.
B. Anorexia nervosa primarily involves severe restriction of food intake, leading to significant weight loss and malnutrition. While physical signs such as brittle hair and dry skin may appear, tooth decay, inflamed throat, and gastroesophageal reflux are less common because purging behaviors are not a defining characteristic.
C. Binge-eating disorder involves consuming large amounts of food in a short period of time, often leading to overweight or obesity. It is not typically associated with purging behaviors, which cause tooth decay, throat inflammation, and reflux.
D. Bulimia nervosa is characterized by recurrent episodes of binge eating followed by compensatory behaviors such as vomiting, laxative use, or excessive exercise. Repeated vomiting exposes the teeth to stomach acid, leading to tooth decay and erosion. It also causes an inflamed throat, gastroesophageal reflux disorder, and dehydration due to fluid loss during purging. These clinical findings align closely with the assessment described.

Correct Answer is C
Explanation
A. Plasma is the straw-colored liquid portion of blood that makes up about 55% of total blood volume. It serves as a medium for transporting nutrients, hormones, electrolytes, and waste products throughout the body. While plasma is crucial for circulation and maintaining blood pressure, it does not carry oxygen directly to tissues. Oxygen transport requires specialized cells and proteins.
B. Platelets, or thrombocytes, are small cell fragments that play a vital role in blood clotting and the repair of damaged blood vessels. While essential for hemostasis, they do not participate in oxygen transport or nutrient delivery to cells.
C. Erythrocytes, also known as red blood cells, are specialized cells whose primary function is the transport of oxygen. Each erythrocyte contains hemoglobin, an iron-containing protein that binds oxygen molecules in the lungs and releases them in tissues where oxygen is needed. Hemoglobin also helps carry carbon dioxide, a metabolic waste product, from tissues back to the lungs for exhalation. The biconcave shape of erythrocytes increases surface area for gas exchange, while their flexibility allows them to navigate through narrow capillaries. Low erythrocyte count or inadequate hemoglobin leads to conditions such as anemia, resulting in fatigue, weakness, and impaired tissue oxygenation.
D. Leukocytes, or white blood cells, are part of the immune system. They defend the body against infections, remove damaged cells, and participate in inflammatory responses. While they are vital for health, they do not transport oxygen to body tissues.
Correct Answer is D
Explanation
A. Glycosylated hemoglobin (HbA1c) is a form of hemoglobin bound to glucose, used as a marker of long-term blood sugar control in diabetes. It is not an energy molecule produced by cells.
B. Saturated fatty acids are a type of dietary fat or stored fat in the body. While they can be broken down to produce energy, they are not the direct energy currency within the cell.
C. Hydrogen phosphate is an ion involved in cellular chemistry and pH buffering, but it is not the main energy molecule for cellular processes.
D. Adenosine triphosphate (ATP) is the primary energy currency of the cell. Cells convert glucose through glycolysis, the Krebs cycle, and oxidative phosphorylation, or fatty acids through beta-oxidation and the Krebs cycle, into ATP. ATP stores energy in its high-energy phosphate bonds and releases it to power cellular processes such as muscle contraction, nerve transmission, active transport, and biosynthesis of macromolecules.
