HESI Pediatrics Practice Exam

Correct Answer: C

Rationale: The correct answer is C. Placing babies on their stomach to sleep increases the risk of sudden infant death syndrome (SIDS). The safest sleep position for infants is on their back to reduce the risk of SIDS. Teaching parents about safe sleep practices is crucial in preventing potential harm to the infant. Choices A, B, and D are all correct statements that promote the well-being of the infant. Feeding the baby in an upright position helps prevent reflux, delaying solid foods until 6 months of age is recommended for proper growth and development, and burping the baby frequently during feedings helps prevent gas buildup and colic.

Correct Answer: C

Rationale: Erythema of the hands and feet is a key diagnostic criterion for Kawasaki disease. This, along with other symptoms like fever and strawberry tongue, helps in making the diagnosis. While desquamation of the palms and soles, cervical lymphadenopathy, and strawberry tongue are associated with Kawasaki disease, the presence of erythema of the hands and feet is particularly significant in diagnosing this condition.

Correct Answer: A

Rationale: In infants, laughing readily and turning from back to side are indicative of normal development. These behaviors indicate that the thyroid therapy is effective, as they suggest the baby is achieving age-appropriate milestones. A 5-month-old infant should be able to laugh readily and turn from back to side, showing progress in motor and social development. Choices B, C, and D describe behaviors that are not specific to the expected developmental milestones of a 5-month-old. Strong Moro and tonic neck reflexes, clenched fists, and limited ability to lift the chest when lying on the abdomen are not necessarily indicative of the effectiveness of thyroid therapy for hypothyroidism.

Correct Answer: C

Rationale: The correct answer is C. Ringworm, a fungal infection, is highly contagious and can be spread by direct contact with infected individuals or animals and indirectly through contaminated objects. It is important for the mother to understand the modes of transmission to prevent the spread of the infection to others and to take necessary precautions to ensure proper treatment and containment of the condition. Choices A and D are incorrect because ringworm is indeed contagious, and it may not always subside spontaneously. Choice B is misleading as tinea infections are not solely indicative of poor hygiene; they can affect anyone, regardless of personal cleanliness.

Correct Answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.
