Correct Answer: B

Rationale: After corrective surgery for hypertrophic pyloric stenosis (HPS), placing the infant in an infant seat is the correct action to take immediately after feeding to limit vomiting. This position helps keep the head elevated, reducing the risk of vomiting. Rocking the infant (Choice A) may agitate the stomach and increase the likelihood of vomiting. Placing the infant flat on the right side (Choice C) is not recommended as it does not encourage proper digestion and may increase the risk of vomiting. Keeping the infant awake with sensory stimulation (Choice D) does not address the positioning concern related to vomiting in this specific post-operative scenario.

Correct Answer: C

Rationale: The correct clinical manifestation the healthcare provider is likely to observe in a child with suspected intussusception is abdominal distension. Intussusception involves one portion of the intestine telescoping into another, causing obstruction. Abdominal distension is a common symptom due to the obstruction and buildup of gas and fluid in the affected area. While projectile vomiting can occur, it is not as specific to intussusception as abdominal distension. Currant jelly stools, which are stools containing blood and mucus, are a classic sign of intussusception but are not a clinical manifestation observable on assessment. Constipation is not typically associated with intussusception, as this condition often presents with symptoms of bowel obstruction rather than constipation.

Correct Answer: B

Rationale: Burns on the lips and singed nasal hairs indicate inhalation injury, suggesting the child has inhaled hot gases or smoke. This presentation is common in cases where the respiratory tract is exposed to hot gases or smoke, leading to potential airway compromise. Choice A, chemical burn, is incorrect because there is no mention of exposure to chemicals, and the symptoms described are more indicative of inhalation injury. Choice C, electrical burn, is incorrect as there is no evidence of electrical involvement in the scenario provided. Choice D, hot-water scald, is incorrect because the presence of singed nasal hairs points more towards inhalation injury than a scald from hot water, emphasizing the need to prioritize airway management and respiratory support.

Correct Answer: B

Rationale: In a situation where a limb is protruding from the vagina during active labor, the correct management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord and improves oxygenation to the fetus. Administering oxygen is important to ensure adequate oxygen supply to both the mother and the baby. Providing transport is necessary for prompt transfer to a medical facility for further management. Applying gentle traction to the protruding limb is not recommended as it can cause harm to the baby and should be avoided. Giving 100% oxygen and attempting to manipulate the protruding limb is not the correct approach and can potentially lead to further complications.

Correct Answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers. Lead exposure can lead to behavioral changes, including irritability, which is crucial for parents to recognize. While abdominal pain and constipation can occur in lead poisoning, they are not as specific or prominent as irritability. Frequent urination is not typically associated with lead poisoning in toddlers, making it a less relevant symptom to emphasize. By highlighting irritability, parents can be better equipped to identify potential signs of lead poisoning in their toddler.
