HESI RN Medical Surgical Practice Exam

Correct Answer: A

Rationale: The best immediate action by the nurse in this situation is to place the client on a cardiac monitor immediately. A serum potassium level of 6.5 mmol/L indicates hyperkalemia, which can lead to life-threatening dysrhythmias. Monitoring the cardiac status is crucial to detect any potential arrhythmias promptly. Teaching the client to limit high-potassium foods (Choice B) may be important for long-term management, but it is not the priority at this moment. Continuing to monitor intake and output (Choice C) is important for assessing renal function but does not address the immediate risk of dysrhythmias. Asking to have the laboratory redraw the blood specimen (Choice D) is unnecessary since the current results indicate a critical situation that requires immediate action.

Correct Answer: C

Rationale: The carina is a cartilaginous ridge that separates the openings of the two main stem (right and left) bronchi. If an endotracheal tube is inserted past the carina, the tube will enter the right main stem bronchus due to the natural curvature of the airway. This positioning is dangerous as only the right lung will be ventilated. It can be identified as only the right lung will have breath sounds and rise and fall with ventilation. Choices A, B, and D are incorrect as they do not relate to the specific anatomical landmark mentioned in the scenario.

Correct Answer: B

Rationale: In nephrotic syndrome, there is significant renal loss of protein leading to hypoalbuminemia and edema formation. If glomerular filtration is normal or near normal, increased protein loss should be matched by an increased intake of protein. Therefore, the correct statement indicating a correct understanding of the nutritional therapy for this condition is increasing protein intake. Decreasing fat, decreasing carbohydrates, or increasing vitamin C intake is not necessary for addressing the underlying issues associated with nephrotic syndrome.

Correct Answer: C

Rationale: An abrupt increase in pain following a percutaneous kidney biopsy may indicate internal hemorrhage. Assessing the client's pulse rate and blood pressure is crucial as changes in vital signs can be indicative of hemorrhage. This assessment is essential in determining the client's hemodynamic status and the need for immediate intervention. Repositioning the client, administering pain medication, or checking urine color are not the priority actions in this situation and may delay necessary interventions for potential hemorrhage.

Correct Answer: C

Rationale: After a nephrostomy, the nurse should assess the client for complications and urgently notify the provider if there is foul-smelling drainage, bloody drainage at the site, or both. Foul-smelling drainage can indicate infection, while bloody drainage may suggest bleeding. Clear drainage is generally normal after a nephrostomy. A headache would not typically be directly related to nephrostomy complications. Therefore, options A and B are correct choices for urgent notification, making option C the correct answer.
