1. What is the most common symptom of gastroesophageal reflux in infants?

• A. Projectile vomiting
• B. Bilious vomiting
• C. Frequent spitting up
• D. Diarrhea

Correct answer: C

Rationale: Frequent spitting up is indeed a common symptom of gastroesophageal reflux in infants. It is caused by the backward flow of stomach contents into the esophagus, leading to infants regurgitating milk or formula shortly after feeding. Projectile vomiting (choice A) is more commonly associated with conditions like pyloric stenosis rather than gastroesophageal reflux. Bilious vomiting (choice B) often indicates an obstruction in the gastrointestinal tract. Diarrhea (choice D) is not typically a primary symptom of gastroesophageal reflux in infants.

2. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

3. Which assessment findings should the nurse expect in a child with sickle cell anemia experiencing an acute vaso-occlusive crisis?

• A. Circulatory collapse, hypovolemia
• B. Cardiomegaly, systolic murmur
• C. Hepatomegaly, intrahepatic cholestasis
• D. Painful swelling of joints in hands and feet, tissue engorgement

Correct answer: D

Rationale: The correct answer is D. Vaso-occlusive crises in sickle cell anemia are characterized by painful swelling of the joints in the hands and feet (hand-foot syndrome) and tissue engorgement due to the obstruction of blood flow by sickled cells. Choices A, B, and C are incorrect because circulatory collapse, hypovolemia, cardiomegaly, systolic murmur, hepatomegaly, and intrahepatic cholestasis are not typically associated with an acute vaso-occlusive crisis in sickle cell anemia.

4. The educator is teaching about the process of physical growth and development. Which of these describes the directional pattern from head to tail?

• A. Cephalodistal
• B. Cephalocaudal
• C. Proximodistal
• D. Proximocaudal

Correct answer: B

Rationale: Cephalocaudal development is the correct term that describes the directional pattern of growth from head to tail. This means that the head and upper body parts develop before the lower parts. Choice A, 'Cephalodistal,' refers to growth from the center of the body outward, not head to tail. Choice C, 'Proximodistal,' describes growth from the center of the body towards the extremities, not specifically from head to tail. Choice D, 'Proximocaudal,' is not a recognized term in the context of physical growth and development.

5. Which disease would require strict isolation of the patient?

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

Correct answer: B

Rationale: The correct answer is B: Chickenpox. Chickenpox is highly infectious and is transmitted through direct contact, droplet spread, and contaminated objects. Due to its high communicability, strict isolation of the patient is necessary to prevent the spread of the disease. Mumps is primarily transmitted through direct contact with the infected person's saliva, with peak contagiousness before the onset of swelling. Exanthema subitum (roseola) has an unknown transmission source. Erythema infectiosum (fifth disease) is contagious before the appearance of symptoms. Therefore, these diseases do not require the same level of strict isolation as chickenpox.
