RN HESI Exit Exam

Correct Answer: A

Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.

Correct Answer: B

Rationale: Heart disease can affect growth, leading to smaller size in children.

Correct Answer: A

Rationale: Administering oxygen therapy is the initial priority in managing chest pain in a client with a history of myocardial infarction. Oxygen therapy helps improve oxygenation, which is crucial in reducing myocardial damage. While administering aspirin and nitroglycerin are essential interventions in the treatment of myocardial infarction, oxygen therapy takes precedence because it addresses the immediate need for oxygen supply to the heart muscle. Obtaining an ECG is important but can be done after ensuring adequate oxygenation.

Correct Answer: B

Rationale: Reorienting the client frequently is the most important nursing intervention in this scenario. It helps reduce confusion and agitation, which are common symptoms of acute delirium in hospitalized elderly clients. Requesting a psychiatric consult (choice A) may be necessary if the reorientation does not improve the client's condition or if there are underlying psychiatric concerns, but reorientation should be attempted first. Administering antipsychotic medications (choice C) should not be the initial intervention as they can have adverse effects in elderly individuals. Obtaining a sitter (choice D) may provide support but does not directly address the client's disorientation and agitation.

Correct Answer: D

Rationale: Nasal flaring with sternal retractions indicates severe respiratory distress in a 1-year-old with bronchiolitis, requiring immediate intervention. Nasal flaring and sternal retractions are signs of increased work of breathing and decreased air movement, indicating the child is struggling to breathe. Wheezing on expiration (Choice A) is common in bronchiolitis but may not require immediate intervention. An oxygen saturation of 90% (Choice B) is low but may not be the most critical finding in this case. A respiratory rate of 40 breaths per minute (Choice C) is elevated but alone may not indicate the need for immediate intervention as much as nasal flaring and sternal retractions.
