HESI Medical Surgical Exam
1. A client who had a C-5 spinal cord injury 2 years ago is admitted to the emergency department with the diagnosis of autonomic dysreflexia secondary to a full bladder. Which assessment finding should the nurse expect this client to exhibit?
- A. Complaints of chest pain and shortness of breath
- B. Hypotension and venous pooling in the extremities
- C. Profuse diaphoresis and severe, pounding headache
- D. Pain and burning sensation upon urination and hematuria
Correct answer: C
Rationale: Autonomic dysreflexia is a life-threatening condition commonly seen in clients with spinal cord injuries above the T6 level. It is characterized by a sudden onset of excessively high blood pressure due to a noxious stimulus below the level of injury, often a distended bladder. The exaggerated sympathetic response leads to vasoconstriction, resulting in symptoms such as profuse diaphoresis (sweating) and a severe, pounding headache. These symptoms are the body's attempt to lower blood pressure. Complaints of chest pain and shortness of breath (Choice A) are not typical findings in autonomic dysreflexia. Hypotension and venous pooling (Choice B) are opposite manifestations of autonomic dysreflexia, which is characterized by hypertension. Pain and burning sensation upon urination and hematuria (Choice D) are indicative of a urinary tract infection and not specific to autonomic dysreflexia.
2. In a patient with anemia, which of the following is the primary symptom to assess?
- A. Fever.
- B. Chest pain.
- C. Shortness of breath.
- D. Muscle cramps.
Correct answer: C
Rationale: The correct answer is C: Shortness of breath. In a patient with anemia, the primary symptom to assess is shortness of breath. Anemia leads to a reduced oxygen-carrying capacity of the blood, resulting in tissues not receiving adequate oxygen. This can manifest as shortness of breath, especially during physical exertion. Fever (Choice A), chest pain (Choice B), and muscle cramps (Choice D) are not typically primary symptoms of anemia. Fever may suggest an infection, chest pain can be indicative of cardiac issues, and muscle cramps may be related to electrolyte imbalances or neuromuscular disorders.
3. A client has a serum potassium level of 6.5 mmol/L, a serum creatinine level of 2 mg/dL, and a urine output of 350 mL/day. What is the best action by the nurse?
- A. Place the client on a cardiac monitor immediately.
- B. Teach the client to limit high-potassium foods.
- C. Continue to monitor the client’s intake and output.
- D. Ask to have the laboratory redraw the blood specimen.
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.
4. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?
- A. 2 mg/dL
- B. 18 mg/dL
- C. 25 mg/dL
- D. 35 mg/dL
Correct answer: B
Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.
5. What should the nurse do before an echocardiogram for a client who has had a myocardial infarction?
- A. Ensuring no food or drink for 4 hours before the procedure
- B. Obtaining informed consent from the client
- C. Assessing for any history of iodine or shellfish allergies
- D. Informing the client about the painless nature and duration of the procedure
Correct answer: D
Rationale: The correct answer is to inform the client that the echocardiogram is a painless procedure that usually takes 30 to 60 minutes to complete. Echocardiography is a noninvasive, risk-free, and pain-free test that uses ultrasound to evaluate the heart's structure and motion. There is no need for special preparation before the procedure. Choices A, B, and C are incorrect because imposing nothing-by-mouth status, obtaining informed consent, and assessing for allergies to iodine or shellfish are not necessary steps before an echocardiogram.
