A nurse is reviewing the laboratory results of an adolescent who has anorexia nervosa. Which of the following findings should the nurse expect?

Hgb 10 g/dL

Blood glucose 100 mg/dL

TIBC 11 mcg/dL

Potassium 3.7 mEq/L

Answer and Explanation

The Correct Answer is A

A. Hgb 10 g/dL
Anemia (low hemoglobin levels) is a common finding in individuals with anorexia nervosa due to inadequate nutrition, leading to a decreased production of red blood cells. Hemoglobin levels below the normal range are often seen in people with severe malnutrition, such as those with anorexia nervosa.

B. Blood glucose 100 mg/dL:
A blood glucose level of 100 mg/dL is within the normal range. Anorexia nervosa typically does not cause specific changes in blood glucose levels.

C. TIBC 11 mcg/dL:
Total Iron-Binding Capacity (TIBC) is a test that measures the blood's capacity to bind to iron. The given value of 11 mcg/dL is unusually low and might not be within the typical reference range. However, the significance of this value is not clear without the specific reference range for the laboratory performing the test.

D. Potassium 3.7 mEq/L:
A potassium level of 3.7 mEq/L is within the normal range. Electrolyte imbalances, including low potassium levels (hypokalemia), can occur in individuals with anorexia nervosa due to inadequate intake and purging behaviors. While this level is within the normal range, individuals with anorexia nervosa may still exhibit electrolyte imbalances that require monitoring and management.

Correct Answer is C

Explanation

A. "Did you experience any childhood trauma?"
Childhood trauma, such as abuse or neglect, can contribute to various mental health conditions, including post-traumatic stress disorder (PTSD), depression, or anxiety disorders. While trauma can impact a person's mental health, it does not directly assess the risk for alcohol use disorder.

B. "Are you the result of a twin birth?"
Being a twin or the result of multiple births does not inherently indicate a risk for alcohol use disorder. This question is related to an individual's birth status and has no direct connection to the assessment of alcohol-related issues.

C. "Have you ever purposefully lost a job?"
This is the correct choice. Purposefully losing a job might indicate behavioral issues related to alcohol misuse or impairment. Individuals with alcohol use disorder may engage in behaviors that lead to job loss, such as absenteeism, poor performance, or conflict at the workplace due to alcohol consumption.

D. "Did your parent have a viral infection while pregnant with you?"
Prenatal viral infections can potentially affect fetal development and lead to certain health conditions. However, this question is not directly related to the risk of alcohol use disorder. Alcohol use disorder is primarily influenced by environmental factors, genetic predisposition, and individual behaviors related to alcohol consumption. Prenatal viral infections are not a typical indicator of alcohol-related concerns.

A. Aspartate aminotransferase 20 units/L B. Platelets 250.000/mm3 C. Sodium 140 mEq/L D. Fasting glucose 175 mg/dL

Correct Answer is D

Explanation

A. Aspartate aminotransferase 20 units/L:
This result indicates the level of an enzyme in the blood. A value of 20 units/L is within the normal range (usually 10-40 units/L). Aspartate aminotransferase (AST) is an enzyme found in the liver, heart, muscles, and other tissues. Elevated levels might indicate liver damage, but 20 units/L is a normal value.

B. Platelets 250,000/mm3:
Platelets are components of blood that help with clotting. A value of 250,000/mm3 is within the normal range (normal range is typically 150,000 to 450,000/mm3). Normal platelet levels are crucial for preventing excessive bleeding or clotting.

C. Sodium 140 mEq/L:
Sodium is an electrolyte essential for maintaining the body's water balance and nerve function. A level of 140 mEq/L falls within the normal range (typically 135-145 mEq/L). Proper sodium levels are important for overall body functioning.

D. Fasting glucose 175 mg/dL:
This indicates the concentration of glucose (sugar) in the blood after a period of fasting. A level of 175 mg/dL is elevated. Fasting glucose levels above 125 mg/dL may suggest diabetes or prediabetes. Elevated glucose levels are a cause for concern as they indicate poor blood sugar regulation, which can lead to various health complications, including diabetes.
