ATI Pediatric Proctored Exam

Correct Answer: A

Rationale: When a child's respirations are slow and shallow due to opioid administration, it results in hypoventilation. This leads to retaining carbon dioxide, indicated by an increased PCO2 level on arterial blood gas analysis, and subsequently causes respiratory acidosis due to the buildup of CO2 in the blood.

Correct Answer: B

Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, which is a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis and may not address the severe manifestations seen in this case.

Correct Answer: B

Rationale: The correct action for the nurse when preparing an adolescent for a lumbar puncture is to apply a topical analgesic cream to the site one hour before the procedure. This helps reduce pain experienced during the lumbar puncture, making the procedure more comfortable for the adolescent.

Correct Answer: D

Rationale: The priority nursing diagnosis for a newborn with esophageal atresia and tracheoesophageal fistula is 'Risk for Aspiration' because of the potential respiratory complications associated with these conditions. The newborn is at a higher risk of aspirating oral or gastric contents due to the abnormal connections between the esophagus and trachea, posing a serious threat to the airway and lungs. Addressing this risk is crucial to prevent respiratory distress and maintain the airway's patency, making it the priority nursing diagnosis in this scenario.

Correct Answer: C

Rationale: The biomechanical model focuses on the physical aspects of performance rather than occupation, making it the correct answer. The Canadian Model of Occupational Performance and Engagement, Person-Environment-Occupation-Participation, and Model of Human Occupation are all occupation-centered models used in occupational therapy.
