HESI Pediatrics Quizlet

Correct Answer: B

Rationale: Encouraging fluid intake is essential in the discharge instructions for a child who has had a tonsillectomy. It helps keep the throat moist, aids in preventing dehydration, and promotes healing. Gargling with salt water is not typically recommended after a tonsillectomy as it may irritate the surgical site. Providing the child with hard candy is not advisable as it can irritate the throat and potentially cause harm. Applying heat to the neck is also not recommended post-tonsillectomy as it can increase swelling and discomfort in the surgical area.

Correct Answer: B

Rationale: Encouraging deep breathing exercises is crucial preoperative teaching for a child scheduled for a tonsillectomy as it helps improve lung function and can prevent postoperative complications like pneumonia. Explaining the procedure in detail may heighten the child's anxiety, making it less ideal. While discussing hydration is important, it may not be the top priority for preoperative teaching for this specific procedure. Play therapy can reduce fear and anxiety, but encouraging deep breathing exercises directly contributes to better postoperative outcomes by enhancing respiratory function.

Correct Answer: D

Rationale: When caring for a child with acute laryngotracheobronchitis, the priority action should be to continually assess the respiratory status. This is crucial to detect early signs of respiratory distress, such as worsening stridor or increased work of breathing. Prompt intervention can prevent further deterioration of the child's condition. Initiating measures to reduce fever (Choice A) may be necessary but is not the priority in this situation. Ensuring delivery of humidified oxygen (Choice B) is important for maintaining oxygenation but should follow the assessment of respiratory status. Providing support to reduce apprehension (Choice C) is also important for the child's comfort but is not the priority over assessing and managing respiratory distress.

Correct Answer: C

Rationale: Positive fibrin split products indicate disseminated intravascular coagulation (DIC), a condition characterized by the widespread formation of blood clots throughout the body. In DIC, clotting factors are consumed, leading to increased fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster blood clotting, which is not consistent with the pathophysiology of DIC. An increased fibrinogen level (Choice B) is also not a characteristic finding in DIC, as fibrinogen levels may be decreased due to consumption in the formation of clots. Increased platelets (Choice D) are not typically observed in DIC; instead, thrombocytopenia (decreased platelet count) is more common due to their consumption in clot formation.

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.
