Correct Answer: D

Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.

Correct Answer: B

Rationale: Encouraging deep breathing exercises is important preoperative teaching for a child scheduled for a tonsillectomy. Deep breathing exercises can help the child relax and reduce anxiety, which is beneficial before the procedure. Explaining the procedure in detail might be overwhelming for a 4-year-old, whereas encouraging deep breathing exercises can be more beneficial in promoting relaxation and preparing the child. Discussing the importance of hydration is crucial for postoperative care but may not be the priority for preoperative teaching. Using play therapy can help prepare the child, but encouraging deep breathing exercises is more directly related to relaxation and preparation for the procedure.

Correct Answer: C

Rationale: In cases of child abuse and ongoing molestation, as described in the scenario, the primary concern is the safety and well-being of the child. Child Protective Services should be notified immediately for intervention to protect the girl and other children in the household from further harm. The police may be involved later to investigate the criminal aspect of the abuse. Notifying the healthcare provider solely to confirm the pregnancy or informing the girl's mother about the positive test result does not address the urgent need for intervention and protection from abuse. Child Protective Services are trained to handle such cases and provide the necessary support and protection for the child and other vulnerable individuals in the family. Immediate action is crucial to ensure the girl's safety and prevent further harm.

Correct Answer: B

Rationale: Peeling skin on the hands and feet is a characteristic clinical manifestation of Kawasaki disease, known as desquamation. This occurs during the convalescent phase of the illness. While Kawasaki disease is associated with a high fever, which is a common early sign, and can also present with other symptoms like conjunctivitis, mucous membrane changes, and lymphadenopathy, the peeling skin on the hands and feet is a classic feature that distinguishes Kawasaki disease from other conditions. Generalized rash is not a specific hallmark of Kawasaki disease, and low-grade fever is not typically associated with this condition. Therefore, the correct answer is B, peeling skin on the hands and feet, which is a key feature of Kawasaki disease.

Correct Answer: A

Rationale: Infection is the most common cause of shock in infants and children due to their increased susceptibility to sepsis. Infants and children have underdeveloped immune systems, making them more prone to infections that can lead to septic shock. While cardiac failure is a serious condition, it is not the most common cause of shock in this population. Accidental poisoning, though dangerous, is less common than infection in causing shock in infants and children. Severe allergic reactions can lead to anaphylactic shock, but they are not as prevalent as infections in causing shock in this age group.
