HESI RN Exit Exam 2023

Correct Answer: A

Rationale: The correct principle of oxygen administration to consider is to avoid administering oxygen at high levels for extended periods. High levels of oxygen for prolonged periods can lead to oxygen toxicity, especially in pediatric patients. Increasing the oxygen flow rate based on tachypnea may not be necessary and can potentially lead to oxygen toxicity. Gradually reducing oxygen levels after symptoms improve may compromise the child's oxygenation. While humidifying oxygen is important to prevent drying of mucous membranes, the primary concern in this case is to avoid high oxygen levels for an extended duration to prevent oxygen toxicity.

Correct Answer: C

Rationale: An ammonia level of 80 mcg/dl is elevated and concerning in a client with liver cirrhosis, as it may indicate hepatic encephalopathy. Elevated ammonia levels can lead to neurological symptoms such as confusion, altered mental status, and even coma. Serum albumin, bilirubin, and prothrombin time are important in liver cirrhosis but are not the most concerning for acute neurological deterioration associated with hepatic encephalopathy.

Correct Answer: C

Rationale: Collecting a urine specimen for routine urinalysis is the next appropriate intervention. The symptoms described, including facial edema and tea-colored urine, are indicative of glomerulonephritis, a condition affecting the kidneys. A urine specimen can help assess renal function and the presence of blood and protein in the urine, which are common in glomerulonephritis. Performing an otoscopic examination (Choice A) is not relevant to the presenting symptoms. Measuring the child's abdominal girth (Choice B) is not necessary at this point as it does not directly address the urinary symptoms. Obtaining a blood specimen for serum electrolytes (Choice D) may provide information about electrolyte imbalances but is not the most appropriate initial step in this case.

Correct Answer: A

Rationale: The correct answer is A: Serum potassium. When a client with chronic kidney disease is receiving erythropoietin therapy, monitoring serum potassium closely is essential. Erythropoietin therapy can lead to increased red blood cell production, which may cause potassium levels to rise, potentially resulting in hyperkalemia. Monitoring potassium levels helps prevent complications associated with hyperkalemia. Choices B, C, and D are incorrect because they are not directly impacted by erythropoietin therapy in the context of CKD.

Correct Answer: A

Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.
