1. Which disease requires strict isolation due to its mode of transmission?

• A. Mumps
• B. Chickenpox
• C. Exanthema subitum (roseola)
• D. Erythema infectiosum (fifth disease)

Correct answer: B

Rationale: The correct answer is Chickenpox (choice B). Chickenpox is highly communicable and requires strict isolation to prevent the spread of the virus through direct contact, droplet transmission, and contaminated objects. Mumps (choice A) is also contagious but does not typically require strict isolation. Exanthema subitum (roseola) (choice C) and Erythema infectiosum (fifth disease) (choice D) are not as highly contagious as chickenpox and do not necessitate strict isolation.

2. 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.

3. Which sign is indicative of developmental dysplasia of the hip in infants?

• A. Ortolani sign
• B. Romberg sign
• C. Trendelenburg sign
• D. Gower's sign

Correct answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

4. What procedure is most appropriate for the assessment of an abdominal circumference related to a bowel obstruction?

• A. Measuring the abdomen after feedings
• B. Marking the point of measurement with a pen
• C. Measuring the circumference at the symphysis pubis
• D. Using a new tape measure with each assessment to ensure accuracy

Correct answer: B

Rationale: Marking the point of measurement ensures consistent and accurate assessments of abdominal circumference, especially important in conditions like bowel obstruction where changes need to be monitored closely.

5. What is the most common piece of medical equipment that can transmit harmful microorganisms among patients?

• A. Thermometer
• B. Stethoscope
• C. Injection needle
• D. Disposable gloves

Correct answer: B

Rationale: The correct answer is B: Stethoscope. A stethoscope is commonly used between patients, and if not correctly disinfected, it can be a dangerous source of spreading microorganisms. Thermometers typically have barriers to prevent this type of transmission. Injection needles are discarded immediately after use and not reused, making them an unlikely source of transmission. Similarly, disposable gloves are not reused, so they are also not a common source of harmful microorganism transmission.
