HESI RN
Evolve HESI Medical Surgical Practice Exam
1. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?
- A. Drugs with a broad spectrum
- B. Drugs with a narrow spectrum
- C. Drugs with a broad therapeutic index
- D. Drugs with a narrow therapeutic index
Correct answer: D
Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
2. A client with type 1 diabetes mellitus has a blood glucose level of 620 mg/dL. After the nurse calls the physician to report the finding and monitors the client closely for:
- A. Metabolic acidosis
- B. Metabolic alkalosis
- C. Respiratory acidosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: In the scenario described, a client with a blood glucose level of 620 mg/dL and type 1 diabetes mellitus is at risk of developing metabolic acidosis. In type 1 diabetes, the lack of sufficient circulating insulin leads to an increase in blood glucose levels. As the body cells utilize all available glucose, the breakdown of fats for energy results in the production of ketones, leading to metabolic acidosis. Metabolic alkalosis, respiratory acidosis, and respiratory alkalosis are not typically associated with uncontrolled type 1 diabetes. Metabolic alkalosis is more commonly linked to conditions such as vomiting or excessive diuretic use, while respiratory acidosis and respiratory alkalosis are related to respiratory system imbalances in carbon dioxide levels.
3. A male client with heart failure presents with shortness of breath, audible wheezing, and pink frothy sputum. What action should the nurse take?
- A. Consult with the charge nurse regarding morphine prescription.
- B. Administer the dose of morphine sulfate as prescribed.
- C. Withhold morphine until dyspnea resolves.
- D. Review the need for the prescription with the healthcare provider.
Correct answer: B
Rationale: The correct answer is B: Administer the dose of morphine sulfate as prescribed. In heart failure, morphine helps reduce anxiety, preload, and afterload on the heart, improving oxygenation. The client's symptoms indicate acute decompensated heart failure, and morphine should be administered promptly to relieve distress. Consulting the charge nurse (Choice A) or withholding morphine (Choice C) would delay necessary treatment. Reviewing the prescription with the healthcare provider (Choice D) is not needed in this acute situation.
4. When should the LPN/LVN encourage the laboring client to begin pushing?
- A. When there is only an anterior or posterior lip of the cervix left.
- B. When the client describes the need to have a bowel movement.
- C. When the cervix is completely dilated.
- D. When the cervix is completely effaced.
Correct answer: C
Rationale: The LPN/LVN should encourage the laboring client to begin pushing when the cervix is completely dilated to 10 centimeters. Pushing before full dilation can lead to cervical injury and ineffective labor progress. By waiting for complete dilation, the client can push effectively, aiding in the descent of the baby through the birth canal. Choices A, B, and D are incorrect because pushing before complete dilation can be harmful and may not effectively help in the descent of the baby. The presence of an anterior or posterior lip of the cervix, the urge to have a bowel movement, or complete effacement of the cervix are not indicators for the initiation of pushing during labor.
5. While removing staples from a male client's postoperative wound site, the nurse observes that the client's eyes are closed and his face and hands are clenched. The client states, 'I just hate having staples removed.' After acknowledging the client's anxiety, what action should the nurse implement?
- A. Attempt to distract the client with general conversation
- B. Administer a pain medication
- C. Continue with the procedure while reassuring the client
- D. Stop the procedure and notify the healthcare provider
Correct answer: A
Rationale: In this situation, the nurse should attempt to distract the client with general conversation. Distracting the client can help reduce anxiety and make the procedure less stressful. Administering pain medication (choice B) is not appropriate as the client's discomfort is related to anxiety, not physical pain. Continuing with the procedure while reassuring the client (choice C) may not address the client's anxiety effectively. Stopping the procedure and notifying the healthcare provider (choice D) is not necessary at this point since the client's anxiety can be managed by attempting to distract him.
