HESI Medical Surgical Exam
1. After a session of hemodialysis, the nurse should monitor the client for which of the following complications of hemodialysis?
- A. Hyperkalemia.
- B. Hypotension.
- C. Infection.
- D. Fever.
Correct answer: B
Rationale: The correct answer is 'B: Hypotension.' Hypotension is a common complication of hemodialysis because fluid removal during the process can lead to a drop in blood pressure. The nurse should closely monitor the client for signs of hypotension such as dizziness, lightheadedness, or a decrease in blood pressure readings. Choice 'A: Hyperkalemia' is incorrect because hemodialysis actually helps lower potassium levels by removing excess potassium from the blood. Choice 'C: Infection' is incorrect as it is not a direct complication of hemodialysis but rather a risk associated with invasive procedures. Choice 'D: Fever' is incorrect as fever is not a typical immediate post-hemodialysis complication unless an underlying infection is present.
2. 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.
3. The nurse is caring for a client who is scheduled for hemodialysis. Which of the following laboratory values should the nurse monitor closely before, during, and after the procedure?
- A. Hemoglobin level.
- B. Blood urea nitrogen (BUN) level.
- C. Creatinine level.
- D. Serum potassium level.
Correct answer: D
Rationale: The correct answer is D: Serum potassium level. Before, during, and after hemodialysis, monitoring the serum potassium level is crucial to prevent hyperkalemia, a potentially life-threatening complication. Hemodialysis is done to remove waste products and excess electrolytes like potassium from the blood. Monitoring other laboratory values like hemoglobin, BUN, and creatinine is important in assessing kidney function and anemia, but serum potassium level requires close monitoring during hemodialysis due to the risk of rapid shifts that can lead to cardiac arrhythmias.
4. A client recovering from a urologic procedure is being assessed by a nurse. Which assessment finding indicates an obstruction of urine flow?
- A. Severe pain
- B. Overflow incontinence
- C. Hypotension
- D. Blood-tinged urine
Correct answer: B
Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.
5. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?
- A. Cardiac output.
- B. Right atrial blood flow.
- C. Left end-diastolic pressure.
- D. Cardiac index.
Correct answer: C
Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.
