HESI Pediatrics Quizlet

Correct Answer: B

Rationale: The short urethra in young girls is a significant factor that predisposes them to urinary tract infections. Girls have a shorter urethra than boys, making it easier for bacteria to travel up the urinary tract, leading to infections. Increased fluid intake (Choice A) is actually a preventive measure as it helps flush out bacteria from the urinary tract. Prostatic secretions in males (Choice C) do not predispose the urinary tract to infection in children. Frequent emptying of the bladder (Choice D) is also a good practice to prevent urinary tract infections by reducing the chances of bacterial growth in the urinary tract.

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: A

Rationale: Preventing shivering is crucial in this situation as it can increase the body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat, potentially worsening the fever. Restricting oral fluids (Choice B) is not appropriate as fluid intake is important to prevent dehydration, especially in a child who has been vomiting. Measuring output hourly (Choice C) and taking vital signs hourly (Choice D) are important nursing actions but not as critical as preventing shivering in this scenario. Therefore, the most important nursing action is to prevent shivering to aid in fever reduction and management.

Correct Answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.

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, typically around 2-3 weeks after the onset of symptoms. While a generalized rash can be present in Kawasaki disease, peeling skin on the hands and feet is a more specific and distinctive feature. High fever is also a common symptom of Kawasaki disease, usually lasting for at least 5 days, while a low-grade fever is not typically associated with this condition. Therefore, the nurse is more likely to observe peeling skin on the hands and feet in a child suspected of having Kawasaki disease, making option B the correct choice.
