Correct Answer: C

Rationale: The correct answer is C. Hepatitis A typically presents with a rapid onset, early fever, and nausea/vomiting. These are common clinical features seen in patients with hepatitis A. A pruritic rash is not commonly associated with hepatitis A, so choice C is incorrect. Choice A and B alone are not sufficient to cover all the clinical features of hepatitis A.

Correct Answer: C

Rationale: The correct answer is C: Pertussis. Pertussis, also known as whooping cough, is characterized by a "whooping" sound during coughing episodes. This distinctive sound is due to the rapid intake of air after a series of coughs. Choice A, Croup, typically presents with a barking cough and stridor. Choice B, Bronchitis, is characterized by a productive cough with mucus. Choice D, Asthma, usually presents with wheezing and shortness of breath.

Correct Answer: B

Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.

Correct Answer: C

Rationale: Raising the patient's head and giving nothing by mouth is crucial in managing tracheoesophageal fistula. This intervention helps prevent aspiration and further complications until surgical correction can be performed. Feeding the neonate or suctioning could exacerbate the condition by risking aspiration. Elevating the head for feedings does not address the primary concern of preventing oral intake, making it less appropriate than the correct answer.

Correct Answer: B

Rationale: Continuous enteral feedings help stimulate the small intestine's adaptation in short bowel syndrome, promoting better nutrient absorption and eventually reducing reliance on TPN. This approach is crucial for long-term management and improving the child's prognosis. Choice A is incorrect because weaning off TPN typically occurs gradually over time, not the next day. Choice C is incorrect because TPN can be adjusted to provide necessary nutrients, and enteral feedings are mainly used to stimulate intestinal function. Choice D is incorrect as the addition of enteral feedings does not necessarily indicate imminent discharge; it primarily focuses on enhancing intestinal adaptation and reducing reliance on TPN.
