HESI Medical Surgical Practice Exam
1. The nurse observes an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation following a transurethral resection of the prostate (TURP). What is the best initial nursing action?
- A. Provide additional oral fluid intake
- B. Measure the client's intake and output
- C. Increase the flow of the bladder irrigation
- D. Administer a PRN dose of an antispasmodic agent
Correct answer: C
Rationale: The best initial nursing action when observing an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation post-TURP is to increase the flow of the bladder irrigation. This action helps prevent blood clots from obstructing the catheter, ensuring effective drainage and promoting client comfort. Providing additional oral fluid intake (Choice A) is important for overall hydration but may not directly address the issue of blood clots in the drainage tubing. Measuring the client's intake and output (Choice B) is a routine nursing assessment that may not directly address the immediate concern of blood clots obstructing the catheter. Administering a PRN dose of an antispasmodic agent (Choice D) is not the best initial action as it does not directly address the issue of blood clots in the drainage tubing.
2. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?
- A. Inform the healthcare provider of the need for potassium replacement.
- B. Prepare to administer a glucose-insulin-potassium replacement.
- C. Change the plan of care to include hourly urinary output measurement.
- D. Instruct the client to increase daily intake of potassium-rich foods.
Correct answer: A
Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.
3. In a patient with chronic kidney disease, which of the following lab values would be expected?
- A. Elevated creatinine levels.
- B. Low hemoglobin levels.
- C. Elevated potassium levels.
- D. Low sodium levels.
Correct answer: A
Rationale: In chronic kidney disease, elevated creatinine levels are expected due to impaired kidney function. Creatinine is a waste product that is typically filtered out by the kidneys. With kidney disease, the clearance of creatinine is reduced, leading to its accumulation in the blood. Low hemoglobin levels (choice B) may be seen in chronic kidney disease due to decreased production of erythropoietin. However, elevated potassium levels (choice C) and low sodium levels (choice D) are more commonly associated with kidney dysfunction but are not as specific indicators of chronic kidney disease as elevated creatinine levels.
4. The client admitted with peripheral vascular disease (PVD) asks the nurse why her legs hurt when she walks. The nurse bases a response on the knowledge that the main characteristic of PVD is:
- A. Decreased blood flow.
- B. Increased blood flow.
- C. Slow blood flow.
- D. Thrombus formation.
Correct answer: A
Rationale: The correct answer is A: 'Decreased blood flow.' In peripheral vascular disease (PVD), there is a narrowing or blockage of blood vessels, leading to reduced blood flow to the extremities. This decreased blood flow results in inadequate oxygen supply to the muscles, causing pain, especially during physical activity when oxygen demand increases. Choice B, 'Increased blood flow,' is incorrect because PVD is characterized by impaired blood circulation rather than increased flow. Choice C, 'Slow blood flow,' is not precise as PVD involves a more significant reduction in blood flow. Choice D, 'Thrombus formation,' is related to the formation of blood clots within vessels, which can be a complication of PVD but is not its main characteristic.
5. A client has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?
- A. Pulse rate
- B. Blood pressure
- C. Pulmonary artery systolic pressure
- D. Pulmonary artery end-diastolic pressure
Correct answer: A
Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.
