HESI Medical Surgical Practice Quiz
1. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?
- A. Contact the provider and recommend discontinuing the metformin.
- B. Keep the client NPO for at least 6 hours prior to the examination.
- C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
- D. Administer intravenous fluids to dilute and increase the excretion of dye.
Correct answer: A
Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.
2. The nurse is caring for a 70-kg patient who is receiving gentamicin (Garamycin) 85 mg 4 times daily. The patient reports experiencing ringing in the ears. The nurse will contact the provider to discuss
- A. decreasing the dose to 50 mg QID.
- B. giving the dose 3 times daily.
- C. obtaining a serum drug level.
- D. ordering a hearing test.
Correct answer: C
Rationale: When a patient receiving gentamicin (Garamycin) reports experiencing ringing in the ears, it is crucial to consider the possibility of ototoxicity. Ototoxicity is a known adverse effect of aminoglycosides. The appropriate action for the nurse in this situation is to contact the provider to discuss obtaining a serum drug level. This is important to assess the drug concentration in the patient's blood, which can help determine if the ringing in the ears is related to the medication. Decreasing the dose or changing the dosing frequency without assessing the serum drug level may not address the underlying issue and could potentially lead to suboptimal treatment. Ordering a hearing test may be necessary at a later stage if the serum drug level indicates a concern. Therefore, option C, obtaining a serum drug level, is the most appropriate action to take in this scenario.
3. A client was admitted for a myocardial infarction and cardiogenic shock 2 days ago. Which laboratory test result should a nurse expect to find?
- A. Blood urea nitrogen (BUN) of 52 mg/dL
- B. Creatinine of 2.3 mg/dL
- C. BUN of 10 mg/dL
- D. BUN/creatinine ratio of 8:1
Correct answer: A
Rationale: In cardiogenic shock, decreased renal perfusion leads to an elevated BUN. Choice A is correct. Creatinine remains normal in cardiogenic shock as it signifies kidney damage, which has not occurred in this case. A low BUN indicates overhydration, malnutrition, or liver damage, which are not typically seen in cardiogenic shock. A low BUN/creatinine ratio is associated with fluid volume excess or acute renal tubular acidosis, not specifically indicative of cardiogenic shock.
4. The nurse is monitoring a client who is receiving continuous ambulatory peritoneal dialysis. The nurse should notify the physician of which of the following findings?
- A. Clear dialysate outflow.
- B. Cloudy dialysate outflow.
- C. Decreased urine output.
- D. Increased blood pressure.
Correct answer: B
Rationale: Cloudy dialysate outflow is an indication of peritonitis, a serious complication of peritoneal dialysis that requires immediate medical attention. Clear dialysate outflow is a normal finding indicating proper dialysis function and should not raise concern. Decreased urine output may be expected in a client undergoing dialysis due to the removal of excess fluids from the body. Increased blood pressure is a common complication in clients with kidney disease but is not directly related to cloudy dialysate outflow.
5. The client with deep vein thrombosis (DVT) in the left lower leg is receiving heparin therapy. Which of the following assessments is the most important for the nurse to perform?
- A. Measure the circumference of the left leg.
- B. Assess for signs of bleeding, such as bruising or hematuria.
- C. Monitor the client's vital signs.
- D. Monitor the client's respiratory status.
Correct answer: B
Rationale: The most important assessment for a client with DVT on heparin therapy is to monitor for signs of bleeding, such as bruising or hematuria. Heparin is an anticoagulant medication that can increase the risk of bleeding. Assessing for bleeding is crucial to prevent complications like hemorrhage. Measuring the circumference of the leg may be relevant for assessing for edema but is not as critical as monitoring for bleeding. Monitoring vital signs and respiratory status are important aspects of care but are not the priority when the client is on heparin therapy for DVT.
