HESI Medical Surgical Practice Quiz
1. The healthcare professional is reviewing a patient’s chart prior to administering gentamicin (Garamycin) and notes that the last serum peak drug level was 9 mcg/mL and the last trough level was 2 mcg/mL. What action will the healthcare professional take?
- A. Administer the next dose as prescribed.
- B. Obtain repeat peak and trough levels before administering the next dose.
- C. Report potential drug toxicity to the patient’s healthcare provider.
- D. Notify the patient’s healthcare provider of decreased drug therapeutic level.
Correct answer: C
Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient’s healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.
2. 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.
3. A client is placed on a mechanical ventilator following a cerebral hemorrhage, and vecuronium bromide (Norcuron) 0.04 mg/kg q12 hours IV is prescribed. What is the priority nursing diagnosis for this client?
- A. Impaired communication related to paralysis of skeletal muscles.
- B. High risk for infection related to increased intracranial pressure.
- C. Potential for injury related to impaired lung expansion.
- D. Social isolation related to inability to communicate.
Correct answer: A
Rationale: The priority nursing diagnosis for a client on a mechanical ventilator receiving vecuronium bromide is 'Impaired communication related to paralysis of skeletal muscles.' Vecuronium is a skeletal muscle relaxant that causes diaphragmatic paralysis, leading to the inability of the client to communicate effectively. This is a crucial nursing concern as it impacts the client's ability to express needs and participate in care. Option B 'High risk for infection related to increased intracranial pressure' is not the priority in this scenario as the client's condition is related to the effects of the medication and mechanical ventilation, not directly to increased intracranial pressure. Option C 'Potential for injury related to impaired lung expansion' is important but not the priority over impaired communication. Option D 'Social isolation related to inability to communicate' is not the priority nursing diagnosis in this situation as it focuses more on psychosocial aspects rather than the immediate physiological concern of communication impairment.
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. The healthcare provider is unable to palpate the client's left pedal pulses. Which of the following actions should the healthcare provider take next?
- A. Auscultate the pulses with a stethoscope.
- B. Call the physician.
- C. Use a Doppler ultrasound device.
- D. Inspect the lower left extremity.
Correct answer: C
Rationale: When pedal pulses are not palpable, using a Doppler ultrasound device is the appropriate next step to locate the pulse. Auscultating the pulses with a stethoscope (Choice A) is used for assessing blood flow in arteries above the clavicle, not for pedal pulses. Calling the physician (Choice B) may be necessary at a later stage, but initially, using a Doppler ultrasound device to locate the pulse is more appropriate. Inspecting the lower left extremity (Choice D) can provide visual information but will not help in locating the pedal pulses, making it a less suitable option.
