A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

Correct Answer: A

Rationale: In this scenario, the patient is experiencing airway compromise due to the fall and potential oropharyngeal obstruction from bleeding. Performing a jaw-thrust maneuver with head stabilization helps maintain the airway patency. The next step should be to suction the oropharynx to clear any blood or secretions, which can obstruct the airway and lead to aspiration. Inserting a nasopharyngeal airway may worsen bleeding or cause further injury to the patient's airway. Initiating positive pressure ventilations can be ineffective if the airway is not cleared first. Administering oxygen via mask is not the immediate priority; ensuring a patent airway by suctioning takes precedence.

Correct Answer: C

Rationale: Infants with Down syndrome are at increased risk of congenital heart defects. Therefore, assessing for abnormal heart sounds is crucial during the physical examination. Bulging fontanels are not typically associated with Down syndrome and may indicate increased intracranial pressure. Stiff lower extremities are not a common finding in Down syndrome and may suggest other musculoskeletal issues. Unusual pupillary reactions are not typically linked to Down syndrome and may be indicative of neurological problems instead.

Correct Answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.

Correct Answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

Correct Answer: C

Rationale: In a child with sickle cell anemia experiencing severe chest pain, fever, cough, and dyspnea, the priority action is to suspect acute chest syndrome, a life-threatening complication. The nurse's first action should be to notify the practitioner for immediate evaluation and intervention. Administering 100% oxygen (Choice A) may be necessary later but is not the initial priority. Administering pain medication (Choice B) should not precede notifying the practitioner, as addressing the underlying cause is crucial. The symptoms described are more indicative of acute chest syndrome than a stroke, so notifying the practitioner for chest syndrome (Choice C) takes precedence over suspecting a stroke (Choice D).
