HESI RN Medical Surgical Practice Exam
1. The healthcare provider caring for a patient who will receive penicillin to treat an infection asks the patient about previous drug reactions. The patient reports having had a rash when taking amoxicillin (Amoxil). The healthcare provider will contact the provider to
- A. discuss giving a smaller dose of penicillin.
- B. discuss using erythromycin (E-mycin) instead of penicillin.
- C. request an order for diphenhydramine (Benadryl).
- D. suggest that the patient receive cefuroxime (Ceftin).
Correct answer: B
Rationale: When a patient reports a previous rash with amoxicillin, which is a type of penicillin, there is a concern for a penicillin allergy. In such cases, using an alternative antibiotic like erythromycin, which is not a penicillin, is the appropriate approach to avoid potential cross-reactivity and allergic reactions. Giving smaller doses of penicillin does not address the underlying allergy issue and can still lead to severe hypersensitivity reactions. Diphenhydramine (Benadryl) is used to manage allergic reactions but should not be the first choice in changing the antibiotic. While some patients allergic to penicillins may also be allergic to cephalosporins like cefuroxime, it is not the best immediate alternative in this scenario.
2. A client presents with a urine specific gravity of 1.018. What action should the nurse take?
- A. Evaluate the client’s intake and output for the past 24 hours.
- B. Document the finding in the chart and continue to monitor.
- C. Obtain a specimen for a urine culture and sensitivity.
- D. Encourage the client to drink more fluids, especially water.
Correct answer: B
Rationale: A urine specific gravity of 1.018 falls within the normal range, indicating adequate hydration. Therefore, the appropriate action is to document this finding in the client's chart and continue monitoring. There is no need to evaluate intake and output, as the specific gravity is normal. Obtaining a urine culture and sensitivity or encouraging increased fluid intake is unnecessary in this situation.
3. What is the primary purpose of administering IV fluids to a patient in septic shock?
- A. To reduce blood pressure.
- B. To increase cardiac output.
- C. To stabilize blood glucose levels.
- D. To maintain adequate tissue perfusion.
Correct answer: D
Rationale: The primary purpose of administering IV fluids to a patient in septic shock is to maintain adequate tissue perfusion. In septic shock, there is a significant drop in blood pressure and systemic vascular resistance leading to poor tissue perfusion. IV fluids help to restore intravascular volume, improve perfusion to vital organs, and prevent organ failure. Choice A ('To reduce blood pressure') is incorrect because IV fluids in septic shock aim to restore tissue perfusion rather than lower blood pressure. Choice B ('To increase cardiac output') is incorrect as the primary goal is to improve tissue perfusion, not specifically increase cardiac output. Choice C ('To stabilize blood glucose levels') is unrelated to the primary purpose of administering IV fluids in septic shock, which is to address the compromised tissue perfusion.
4. In a patient with chronic obstructive pulmonary disease (COPD), which of the following interventions is most important?
- A. Encouraging the patient to stop smoking.
- B. Administering bronchodilators.
- C. Monitoring oxygen saturation.
- D. Providing nutritional support.
Correct answer: C
Rationale: Monitoring oxygen saturation is the most important intervention in a patient with COPD because it helps assess the adequacy of oxygenation. In COPD, patients often have compromised lung function, leading to decreased oxygen levels in the blood. Monitoring oxygen saturation allows healthcare providers to promptly identify and address any potential hypoxemia, which is vital in managing COPD exacerbations. While encouraging the patient to stop smoking (Choice A) is critical for long-term management, monitoring oxygen saturation takes precedence in the immediate care of a COPD patient. Administering bronchodilators (Choice B) and providing nutritional support (Choice D) are important aspects of managing COPD but are secondary to monitoring oxygen saturation, which directly impacts the patient's oxygenation status.
5. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?
- A. Use the catheter for the next laboratory blood draw.
- B. Monitor the central venous pressure through this line.
- C. Access the line for the next intravenous medication.
- D. Place a heparin or heparin/saline dwell after hemodialysis.
Correct answer: D
Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.
