HESI Medical Surgical Practice Quiz
1. The patient is taking low-dose erythromycin prophylactically and will start cefaclor for treating an acute infection. The nurse should discuss this with the provider because taking both medications simultaneously can cause which effect?
- A. Decreased effectiveness of cefaclor.
- B. Increased effectiveness of cefaclor.
- C. Decreased effectiveness of erythromycin.
- D. Increased effectiveness of erythromycin.
Correct answer: A
Rationale: When erythromycin and cefaclor are taken together, erythromycin can inhibit the metabolism of cefaclor, leading to elevated cefaclor levels and potentially causing adverse effects. This results in a decrease in the effectiveness of cefaclor. Therefore, the nurse should discuss this potential drug interaction with the provider to consider an alternative treatment or adjust the dosages to prevent complications. Choices B, C, and D are incorrect because the concern lies with the effect on cefaclor when combined with erythromycin, not the effect on erythromycin itself.
2. The nurse is caring for a patient who has recurrent urinary tract infections. The patient’s current infection is not responding to an antibiotic that has been used successfully several times in the past. The nurse understands that this is most likely due to
- A. acquired bacterial resistance.
- B. cross-resistance.
- C. inherent bacterial resistance.
- D. transferred resistance.
Correct answer: A
Rationale: The correct answer is A: acquired bacterial resistance. Acquired resistance happens when an organism has been exposed to the antibacterial drug, making it less effective over time. Cross-resistance (B) occurs when resistance to one drug leads to resistance to another. Inherent resistance (C) happens without prior exposure to the drug, meaning the bacteria are naturally resistant. Transferred resistance (D) involves the transfer of resistant genes from one organism to another, contributing to resistance development.
3. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)
- A. Man with prostate cancer
- B. Woman with blood clots in the urinary tract
- C. Client with ureterolithiasis
- D. All of the above
Correct answer: D
Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.
4. Alteplase recombinant, or tissue plasminogen activator (t-PA), a thrombolytic enzyme, is administered during the first 6 hours after onset of myocardial infarction (MI) to:
- A. Control chest pain.
- B. Reduce coronary artery vasospasm.
- C. Control the arrhythmias associated with MI.
- D. Revascularize the blocked coronary artery.
Correct answer: D
Rationale: Alteplase recombinant, or t-PA, is a thrombolytic enzyme used to dissolve clots and revascularize the blocked coronary artery in patients experiencing a myocardial infarction (MI). Administering t-PA within the first 6 hours of MI onset is crucial to restore blood flow to the affected area and minimize cardiac tissue damage. Therefore, the correct answer is to revascularize the blocked coronary artery. Choices A, B, and C are incorrect because while controlling chest pain, reducing coronary artery vasospasm, and managing arrhythmias are important goals in managing MI, the primary purpose of administering t-PA within the first 6 hours is to restore blood flow by dissolving clots and revascularizing the blocked coronary artery.
5. When giving a report about a client who had a gastrectomy from the intensive care unit to the post-surgical unit nurse, what is the most effective way to assure essential information is reported?
- A. Give the report face-to-face with both nurses in a quiet room.
- B. Audiotape the report for future reference and documentation.
- C. Use a printed checklist with information individualized for the client.
- D. Document essential transfer information in the client's electronic health record.
Correct answer: C
Rationale: Using a printed checklist with individualized information is the most effective way to ensure that all key details about the client who had a gastrectomy are covered during the report. This method helps in structuring the information systematically, reducing the risk of missing important details. Face-to-face communication in a quiet room (Choice A) is important for effective communication but may not guarantee the coverage of all essential information. Audiotaping the report (Choice B) may not be practical for immediate reference or interaction. Documenting in the electronic health record (Choice D) is essential but may not facilitate a comprehensive real-time exchange of information between the nurses.
