Evolve HESI Medical Surgical Practice Exam
1. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?
- A. Request an order for IV epinephrine to treat anaphylactic shock.
- B. Slow the infusion to 10 mg/min and observe the patient closely.
- C. Stop the infusion and obtain an order for a BUN and serum creatinine.
- D. Suspect Stevens-Johnson syndrome and notify the provider immediately.
Correct answer: B
Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.
2. After a client with peripheral vascular disease undergoes a right femoral-popliteal bypass graft, their blood pressure drops from 124/80 to 94/62. What should the nurse assess first?
- A. IV fluid infusion.
- B. Pedal pulses.
- C. Nasal cannula oxygen flow rate.
- D. Capillary refill time.
Correct answer: B
Rationale: Assessing pedal pulses is crucial in this situation as it helps determine the adequacy of perfusion to the lower extremity following a bypass graft. A decrease in blood pressure postoperatively could indicate decreased perfusion, making the assessment of pedal pulses a priority to ensure proper circulation. Checking IV fluid infusion, nasal cannula oxygen flow rate, or capillary refill time are not the immediate priorities in this scenario and would not provide direct information about perfusion to the affected extremity.
3. A client who was involved in a motor vehicle collision is admitted with a fractured left femur that is immobilized using a fracture traction splint in preparation for an open reduction internal fixation (ORIF). The nurse determines that the client's distal pulses are diminished in the left foot. Which intervention should the nurse implement?
- A. Verify pedal pulses using a Doppler pulse device
- B. Evaluate the application of the splint to the left leg
- C. Offer ice chips and clear oral liquids
- D. Monitor the left leg for pain, pallor, paresthesia, paralysis, pressure
Correct answer: B
Rationale: Evaluating the application of the splint is the priority as it ensures it is not too tight, which could impair circulation and exacerbate the diminished pulses. Verifying pedal pulses with a Doppler pulse device may be indicated but does not directly address the immediate concern of proper splint application. Offering ice chips and clear oral liquids would not address the issue of diminished distal pulses. Monitoring the left leg for pain, pallor, paresthesia, paralysis, and pressure is important but would not directly address the cause of the diminished pulses in this scenario.
4. The healthcare provider prescribes diagnostic tests for a client with pneumonia identified on a chest X-ray. Which diagnostic test should the nurse review for implementation to guide the most therapeutic treatment of pneumonia?
- A. Sputum culture and sensitivity
- B. Blood cultures
- C. Arterial blood gases (ABG)
- D. Computerized tomography (CT) of the chest
Correct answer: A
Rationale: Sputum culture and sensitivity is the most appropriate diagnostic test for pneumonia as it helps in identifying the causative organism, which is crucial for guiding the selection of the most effective antibiotic therapy. Blood cultures (choice B) are more useful in identifying systemic infections rather than pneumonia specifically. Arterial blood gases (ABG) (choice C) are helpful in assessing oxygenation but do not directly aid in identifying the causative organism. Computerized tomography (CT) of the chest (choice D) is useful for evaluating structural abnormalities in the lungs but is not the initial test of choice for diagnosing pneumonia.
5. A female patient will receive doxycycline to treat a sexually transmitted infection (STI). What information will the nurse include when teaching this patient about this medication?
- A. Nausea and vomiting are uncommon adverse effects.
- B. The drug may cause possible teratogenic effects.
- C. Increase intake of dairy products with each dose of this medication.
- D. Use a backup method of contraception if taking oral contraceptives.
Correct answer: D
Rationale: The correct answer is D. The desired action of oral contraceptives can be reduced when taken with tetracyclines like doxycycline. Therefore, patients on oral contraceptives should be advised to use a backup contraception method while taking doxycycline. Choice A is incorrect because nausea and vomiting are common adverse effects of doxycycline. Choice B is incorrect because doxycycline is not known for causing teratogenic effects. Choice C is incorrect because dairy products can interfere with the absorption of doxycycline, so they should be avoided when taking this medication.
