1. What organism is a parasite that causes acute diarrhea?

• A. Shigella organisms
• B. Salmonella organisms
• C. Giardia lamblia
• D. Escherichia coli

Correct answer: C

Rationale: Giardia lamblia is a protozoan parasite known to cause acute diarrhea, often through contaminated water or food. Shigella, Salmonella, and E. coli are bacterial pathogens that also cause diarrhea but are not parasites.

2. The nurse is assessing a child suspected of having pinworms. Which is the most common symptom the nurse expects to assess?

• A. Restlessness
• B. Distractibility
• C. Rectal discharge
• D. Intense perianal itching

Correct answer: D

Rationale: Intense perianal itching is the most common symptom of pinworm infection, especially at night when the female worms lay their eggs

3. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

4. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

5. What is the most frequent cause of hypovolemic shock in children?

• A. Sepsis
• B. Blood loss
• C. Anaphylaxis
• D. Heart failure

Correct answer: B

Rationale: Hypovolemic shock in children is most frequently caused by blood loss, which can result from trauma, surgery, or gastrointestinal bleeding. Sepsis and anaphylaxis can lead to different types of shock (septic and anaphylactic), and heart failure is related to cardiogenic shock.
