Pediatric HESI 2024

Correct Answer: A

Rationale: The nurse should suspect measles based on the symptoms described, including the presence of Koplik spots (small, red spots with blue-white centers in the mouth). Measles typically presents with fever, irritability, runny nose, and a rash that begins on the face and spreads downward. Chickenpox (choice B) presents with vesicular lesions in different stages of healing and usually starts on the trunk. Fifth disease (choice C) presents with a 'slapped cheek' rash on the face and can cause joint pain. Scarlet fever (choice D) is characterized by a sandpaper-like rash, fever, and strawberry tongue.

Correct Answer: D

Rationale: The correct answer is D: "These responses are replaced by voluntary activity at about five months of age." The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. Choice A is incorrect because checking the responses before deciding a course of action does not address the developmental milestone related to the reflexes. Choice B is incorrect as it jumps to a conclusion of developmental delay without considering the normal developmental process. Choice C is incorrect as additional sensory stimulation is not necessary for the return of these reflexes, as they are expected to naturally diminish as part of normal development.

Correct Answer: A

Rationale: The nurse should suspect measles in this child. The presence of a high fever, irritability, runny nose, rash, and Koplik spots (small, red spots with blue-white centers in the mouth) are classic signs of measles. Measles is a highly contagious viral illness that can lead to serious complications if not managed promptly. Chickenpox (choice B) presents with a different rash pattern and does not typically involve Koplik spots. Fifth disease (choice C) and scarlet fever (choice D) also have distinct clinical presentations and are not characterized by the specific symptoms described in this case.

Correct Answer: C

Rationale: Delayed physical growth is a common finding in most children with symptomatic cardiac malformations. This occurs due to inadequate oxygenation and nutrient supply to tissues as a result of the cardiac defect. Mental retardation (Choice A) is not typically associated with cardiac malformations unless there are complications affecting brain function. Inherited genetic factors (Choice B) may contribute to the development of cardiac malformations but are not a direct common finding in affected children. Clubbing of the fingertips (Choice D) is more commonly associated with chronic respiratory or cardiac conditions, not specifically cardiac malformations in children.

Correct Answer: D

Rationale: Cleft palate is considered a major congenital anomaly due to its significant impact on feeding, speech, and overall health. Overlapping digits (Option A) are a physical anomaly but not typically considered a major congenital anomaly. Polydactyly (Option B) refers to having extra fingers or toes, which is a congenital anomaly but not as major as a cleft palate. Umbilical hernia (Option C) involves a protrusion of abdominal contents through the umbilical ring but is not typically classified as a major congenital anomaly compared to cleft palate.
