HESI RN Medical Surgical Practice Exam
1. The nurse is caring for a patient who is ordered to receive PO trimethoprim-sulfamethoxazole (TMP-SMX) 160/800 QID to treat a urinary tract infection caused by E. coli. The nurse will contact the provider to clarify the correct
- A. dose.
- B. drug.
- C. frequency.
- D. route.
Correct answer: C
Rationale: The correct answer is 'frequency.' Trimethoprim-sulfamethoxazole (TMP-SMX) is typically prescribed to be taken twice daily, not four times a day (QID). The dose, drug, and route are already specified in the order, so the nurse should contact the provider to clarify the frequency of administration to ensure optimal treatment for the urinary tract infection caused by E. coli. Choosing 'dose' is incorrect because the dose of 160/800 is already provided in the order. 'Drug' is incorrect because the medication Trimethoprim-sulfamethoxazole (TMP-SMX) is explicitly stated in the prescription. 'Route' is incorrect as PO (by mouth) is also clearly indicated in the prescription.
2. The client is planning care for a client who is receiving hemodialysis. Which of the following interventions should be included in the plan of care?
- A. Administer anticoagulants to prevent clot formation.
- B. Monitor the client for signs of infection.
- C. Provide the client with a high-protein diet.
- D. Encourage the client to drink at least 2 liters of fluid daily.
Correct answer: B
Rationale: Monitoring for signs of infection is crucial in clients receiving hemodialysis because they are at an increased risk of infection due to the invasive nature of the procedure. Administering anticoagulants is not typically a part of the routine care for clients undergoing hemodialysis unless specifically prescribed. While a high-protein diet may be beneficial for some clients, it is not a specific intervention related to hemodialysis. Encouraging fluid intake must be individualized based on the client's fluid status and should not be a generalized recommendation for all clients receiving hemodialysis.
3. A patient who is being treated for dehydration is receiving 5% dextrose and 0.45% normal saline with 20 mEq/L potassium chloride at a rate of 125 mL/hour. The nurse assuming care for the patient reviews the patient’s serum electrolytes and notes a serum sodium level of 140 mEq/L and a serum potassium level of 3.6 mEq/L. The patient had a urine output of 250 mL during the last 12-hour shift. Which action will the nurse take?
- A. Contact the patient’s provider to discuss increasing the potassium chloride to 40 mEq/L.
- B. Continue the intravenous fluids as ordered and reassess the patient frequently.
- C. Notify the provider and discuss increasing the rate of fluids to 200 mL/hour.
- D. Stop the intravenous fluids and notify the provider of the assessment findings.
Correct answer: D
Rationale: The patient’s potassium level is within normal limits, but the decreased urine output indicates the patient should not receive additional IV potassium. Increasing potassium chloride to 40 mEq/L is not needed as the level is normal. Stopping the IV fluids is appropriate due to the decreased urine output, which suggests potential fluid overload. The nurse should notify the provider of the assessment findings for further management. Increasing the rate of fluids to 200 mL/hour is not recommended without addressing the decreased urine output first.
4. A client has a urine specific gravity of 1.040. What action should the nurse take?
- A. Obtain a urine culture and sensitivity.
- B. Place the client on restricted fluids.
- C. Assess the client’s creatinine level.
- D. Increase the client’s fluid intake.
Correct answer: D
Rationale: A urine specific gravity of 1.040 is higher than the normal range (1.005 to 1.030) and can indicate dehydration, decreased kidney blood flow, or the presence of antidiuretic hormone. In this situation, the priority action should be to increase the client's fluid intake to address the high specific gravity. Obtaining a urine culture, placing the client on restricted fluids, or assessing the creatinine level would not directly address the underlying issue of high urine specific gravity caused by dehydration or other factors.
5. A client is placed on fluid restrictions because of chronic kidney disease (CKD). Which assessment finding would alert the nurse that the client’s fluid balance is stable at this time?
- A. Decreased calcium levels
- B. Increased phosphorus levels
- C. No adventitious sounds in the lungs
- D. Increased edema in the legs
Correct answer: C
Rationale: The absence of adventitious sounds upon auscultation of the lungs is a key indicator that the client's fluid balance is stable. Adventitious sounds, such as crackles or wheezes, are typically heard in conditions of fluid overload, indicating that the body is retaining excess fluid. Choices A and B, decreased calcium levels and increased phosphorus levels, are common laboratory findings associated with chronic kidney disease (CKD) and are not directly related to fluid balance. Increased edema in the legs is a sign of fluid imbalance, suggesting fluid retention in the tissues, which would not indicate stable fluid balance in a client with CKD on fluid restrictions.
