 ANSWERS TO DIARRHEA AND DEHYDRATION MCQ

Here are the answers and explanations for the previous questions, along with 10 important points that can be used as the basis for additional MCQs:

Questions on DIARRHEA AND DEHYDRATION MCQ

**Question 1: What is the primary cause of diarrhea?**

Answer: B) Viral or bacterial infections

Explanation: Diarrhea is primarily caused by viral or bacterial infections that lead to inflammation and irritation of the intestines, resulting in increased fluid secretion and frequent bowel movements.

**Question 2: Which of the following is a common symptom of dehydration?**

Answer: C) Muscle cramps

Explanation: Muscle cramps are a common symptom of dehydration. When the body lacks sufficient fluids, electrolyte imbalances can occur, leading to muscle spasms and cramps.

**Question 3: How does diarrhea contribute to dehydration?**

Answer: C) It leads to frequent and fluid-rich stools

Explanation: Diarrhea leads to frequent and fluid-rich stools, causing a significant loss of water and electrolytes from the body, which can result in dehydration if not adequately replenished.

**Question 4: What is the recommended first-aid treatment for a person experiencing dehydration due to diarrhea?**

Answer: C) Drinking oral rehydration solutions (ORS)

Explanation: Oral rehydration solutions (ORS) contain the right balance of electrolytes and fluids to help replace the lost fluids due to diarrhea and prevent dehydration.

**Question 5: In severe cases of dehydration, which of the following medical interventions might be necessary?**

Answer: D) Intravenous (IV) fluid therapy

Explanation: In severe cases of dehydration, when oral rehydration is not sufficient, intravenous (IV) fluid therapy might be necessary to rapidly restore fluid and electrolyte balance.

LFT- Liver function test: Indication, Interpretatin, Normal Range

LFT- Liver function test: Indication, Interpretatin, Normal Range

Table of Contents(toc)

🧾 Introduction

Liver Function Tests (LFTs) are a panel of blood tests used to evaluate the overall health and function of the liver. These tests help detect liver inflammation (hepatitis), infection, damage, obstruction, and synthetic dysfunction. They are crucial in diagnosing liver diseases such as hepatitis, cirrhosis, alcoholic liver disease, drug-induced liver injury, and biliary obstruction.

📊 Normal Values of Key Liver Function Tests

🔬 Interpreting Abnormal Liver Function Tests

1. Hepatocellular Pattern (↑ALT, ↑AST)

• Causes:

  • Viral Hepatitis (A, B, C)

  • Drug-induced liver injury (e.g., acetaminophen)

  • Autoimmune hepatitis

  • Ischemic hepatitis

• AST/ALT Ratio:

  • 2:1 → suggestive of alcoholic hepatitis

  • ALT > AST → typical of viral hepatitis

2. Cholestatic Pattern (↑ALP, ↑GGT)

• Causes:

  • Biliary obstruction (e.g., gallstones, tumors)

  • Primary biliary cholangitis

  • Primary sclerosing cholangitis

  • Drug-induced cholestasis

• GGT is often used to confirm hepatic origin of ALP elevation.

3. Mixed Pattern (↑ALT, ↑ALP)

• Seen in:

  • Drug-induced liver injury

  • Viral hepatitis

  • Autoimmune disorders

4. Synthetic Dysfunction (↓Albumin, ↑PT/INR)

• Seen in:

  • Chronic liver disease (cirrhosis)

  • Acute liver failure

---

🧠 Clinical Clues from Patterns

Pattern	Key Indicators	Common Conditions
Hepatocellular	↑ALT, ↑AST	Hepatitis (viral, toxic, autoimmune)
Cholestatic	↑ALP, ↑GGT, ↑Bilirubin	Obstruction, PBC, PSC
Synthetic failure	↓Albumin, ↑PT/INR	Cirrhosis, liver failure
Isolated ↑ALP	If GGT normal → think bone disease

⚠️ Special Notes for Exams

• ALT is more liver-specific than AST.

• AST is also found in muscle, RBCs, and heart → check CK if muscle injury is suspected.

• Bilirubin types:

  • Unconjugated ↑ in hemolysis and Gilbert’s syndrome

  • Conjugated ↑ in cholestasis and hepatocellular disease

• GGT is elevated in alcoholic liver disease, but not bone disease.

• Prothrombin time is often the first to derange in acute liver failure.

📚 High-Yield MCQs for Licensing Exams (USMLE, NCLEX, FMGE)

1. A 45-year-old male with a history of alcohol use presents with fatigue and jaundice. LFTs show AST 145 U/L and ALT 60 U/L. What is the most likely diagnosis?

A. Viral hepatitis

B. Alcoholic hepatitis ✅

C. Hemochromatosis

D. Primary biliary cholangitis

Explanation: AST:ALT > 2 is characteristic of alcoholic hepatitis.

2. A patient presents with jaundice, dark urine, and pale stools. Labs show ALP 320 U/L, GGT elevated, and direct bilirubin 4.5 mg/dL. What is the likely diagnosis?

A. Viral hepatitis

B. Hemolytic anemia

C. Obstructive jaundice ✅

D. Gilbert syndrome

Explanation: Cholestatic pattern with elevated ALP, GGT, and direct bilirubin → biliary obstruction.

3. Which LFT abnormality is most indicative of impaired liver synthetic function?

A. Elevated ALT

B. Elevated AST

C. Low albumin and elevated PT/INR ✅

D. High GGT

Explanation: PT and albumin reflect liver synthesis of proteins and clotting factors.

4. In acute viral hepatitis, which of the following is the most likely pattern?

A. ALT > AST ✅

B. AST > ALT

C. Isolated ALP elevation

D. Normal LFTs
