Question 1

With one exception, all of these are mediated by the digestive hormone gastrin.

Accepted Answer

Reduced of pepsinogen production by the stomach

Answer

Gastrin is a digestive hormone primarily responsible for stimulating gastric acid (HCl) secretion by parietal cells and increasing pepsinogen secretion by chief cells. It also enhances gastric motility and increases the pressure of the lower esophageal sphincter. Therefore, reducing pepsinogen production is an untrue statement regarding gastrin's actions, as it actually increases it.

Question 2

Moreover, impaired glucose tolerance is distinguished by:

Accepted Answer

A fasting plasma glucose of 100-125 mg/dl

Answer

Impaired glucose tolerance (IGT) is a prediabetic state characterized by a fasting plasma glucose (FPG) level between 100-125 mg/dL (5.6-6.9 mmol/L), also known as impaired fasting glucose (IFG). This indicates that blood glucose levels are higher than normal but not yet high enough for a diabetes diagnosis, signifying an increased risk for developing type 2 diabetes.

Question 3

Regarding the low amount of serum albumin, which of these is untrue?

Accepted Answer

It can be used to identify esophageal reflux

Answer

Low serum albumin is a common finding in conditions like nephrotic syndrome (due to protein loss), kwashiorkor (severe protein malnutrition), and ascites (due to reduced oncotic pressure). However, serum albumin levels are not a diagnostic marker for esophageal reflux. Esophageal reflux is typically diagnosed based on symptoms, endoscopy, or pH monitoring.

Question 4

The purpose of cystic fibrosis treatment is to:

Accepted Answer

To increase fat and protein & Replacement of Pancreatic enzyme

Answer

Cystic fibrosis causes pancreatic insufficiency, leading to malabsorption of fats, proteins, and fat-soluble vitamins. Therefore, pancreatic enzyme replacement is essential to improve digestion and nutrient absorption. Additionally, patients with cystic fibrosis have increased energy needs due to chronic infection and malabsorption, requiring significantly higher intakes of energy, protein, and fat to maintain nutritional status and support growth.

Question 5

The phenylketonuria test that is used to identify

Accepted Answer

Guthrie test

Answer

The Guthrie test is a widely recognized and utilized screening method for diagnosing Phenylketonuria (PKU) in newborns. This test detects elevated levels of phenylalanine in a blood sample, indicating the genetic disorder where the body cannot properly metabolize this amino acid. Early diagnosis through the Guthrie test is crucial for initiating treatment and preventing severe neurological damage.
