HESI 799 RN Exit Exam

Correct Answer: C

Rationale: Assessing the client's oxygen saturation is the first priority in managing a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. Monitoring oxygen saturation levels helps in determining the effectiveness of the oxygen therapy and if adjustments are needed. Elevating the head of the bed can help with breathing but is not the first priority. Administering oxygen therapy as prescribed is important, but assessing the current oxygen saturation comes before administering more oxygen. Obtaining an arterial blood gas (ABG) sample may provide valuable information, but it is not the initial intervention needed in this situation.

Correct Answer: A

Rationale: The correct answer is A: 'Expresses an understanding of the procedure.' This choice indicates that the client is mentally prepared for the pulmonary function tests, as understanding the procedure shows readiness and cooperation. Choices B, C, and D are incorrect. Choice B, 'NPO for 6 hrs,' pertains to fasting status and is not directly related to readiness for the test. Choice C, 'No known drug allergies,' is important information but does not specifically indicate readiness for pulmonary function tests. Choice D, 'Intravenous access intact,' is related to vascular access and not a direct indicator of readiness for the pulmonary function tests.

Correct Answer: A

Rationale: After an open reduction of the tibia, bleeding on the cast can be a concern. Outlining the area with ink and monitoring it every 15 minutes is the appropriate action to assess if the bleeding is worsening, indicating the need for further intervention. This action allows for close observation without disturbing the cast. Choice B is incorrect because while notifying the healthcare provider is important, immediate action is not always necessary if the bleeding is not severe. Choice C is incorrect because applying a new cast is not the standard intervention for bleeding on a cast. Choice D is incorrect because elevating the limb may not address the underlying cause of bleeding and may not be the most appropriate action at this time.

Correct Answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.

Correct Answer: A

Rationale: The client is exhibiting signs of severe anemia and hypovolemic shock, indicated by low hemoglobin levels and hypotension. The first priority is to address the low hemoglobin by transfusing packed red blood cells to improve oxygen-carrying capacity and perfusion to vital organs. While obtaining blood and sputum cultures is important for identifying potential infections, infusing normal saline can help with volume expansion but does not address the primary issue of severe anemia. Titrating oxygen to maintain an oxygen saturation of 90% is crucial but should follow the administration of packed red blood cells to optimize oxygen delivery.
