After instituting ordered measures to reduce the fever in a 3-year-old with fever and vomiting, what nursing action is most important for the nurse in the emergency department to take?

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: 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: D

Rationale: The most common treatment for Hirschsprung disease is the surgical removal of the affected section of the bowel. This procedure entails excising the part of the colon that lacks nerve cells crucial for normal bowel function. Daily enemas (Choice A) can offer temporary relief for constipation but do not address the root cause of the condition, which is the absence of nerve cells. A low-fiber diet (Choice B) is not a primary therapy for Hirschsprung disease and may not effectively manage the disorder. A permanent colostomy (Choice C) is typically considered in severe cases where other interventions have failed and is not the standard management approach for Hirschsprung disease.

Correct Answer: A

Rationale: The correct answer is to notify the practitioner. The passage of a normal brown stool in a child with intussusception could indicate spontaneous reduction of the intussusception. It is crucial to inform the practitioner immediately so that they can reassess the situation and determine the next steps, which may include adjusting the planned intervention. Measuring abdominal girth (choice B) may be important in assessing for abdominal distension but is not the most immediate action required in this scenario. Auscultating for bowel sounds (choice C) is a routine nursing assessment but does not take precedence over notifying the practitioner in this critical situation. Taking vital signs, including blood pressure (choice D), is also important but notifying the practitioner is more urgent to address the unexpected change in the patient's condition.

Correct Answer: D

Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.
