HESI 799 RN Exit Exam

Correct Answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.

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: C

Rationale: The correct answer is C. Fresh fruit salad with low-fat yogurt is a healthier choice for managing the diet of a 12-year-old boy with a high BMI and elevated HBA1C. This choice provides a good balance of nutrients, fiber, and low-fat content, helping to lower BMI and maintain healthy blood sugar levels. Choices A, B, and D are less ideal as they contain higher levels of refined carbohydrates, saturated fats, and sugars, which can contribute to weight gain and worsen blood sugar control in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.

Correct Answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.
