HESI Medical Surgical Practice Exam
1. Which of the following lab values would be most concerning in a patient receiving heparin therapy?
- A. Elevated hemoglobin levels.
- B. Low platelet count.
- C. High potassium levels.
- D. Low sodium levels.
Correct answer: B
Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.
2. The nurse is caring for five clients on the medical-surgical unit. Which clients would the nurse consider to be at risk for post-renal acute kidney injury (AKI)? (Select all that apply.)
- A. Man with prostate cancer
- B. Woman with blood clots in the urinary tract
- C. Client with ureterolithiasis
- D. All of the above
Correct answer: D
Rationale: Post-renal acute kidney injury (AKI) occurs due to urine flow obstruction, which can result from conditions such as prostate cancer, blood clots in the urinary tract, and ureterolithiasis (kidney stones). Severe burns would lead to pre-renal AKI by reducing blood flow to the kidneys. Lupus would cause intrarenal AKI by affecting the kidney tissue directly. Therefore, options A, B, and C are correct choices for clients at risk for post-renal AKI, making option D the correct answer.
3. The nurse assumes care for a patient who is currently receiving a dose of intravenous vancomycin (Vancocin) infusing at 20 mg/min. The nurse notes red blotches on the patient’s face, neck, and chest and assesses a blood pressure of 80/55 mm Hg. Which action will the nurse take?
- A. Request an order for IV epinephrine to treat anaphylactic shock.
- B. Slow the infusion to 10 mg/min and observe the patient closely.
- C. Stop the infusion and obtain an order for a BUN and serum creatinine.
- D. Suspect Stevens-Johnson syndrome and notify the provider immediately.
Correct answer: B
Rationale: When vancomycin is infused too rapidly, “red man” syndrome may occur; the rate should be 10 mg/min to prevent this. This is a toxic reaction, not an allergic one, so epinephrine is not indicated. Stevens-Johnson syndrome is characterized by a rash and fever. Red man syndrome is not related to renal function.
4. After delegating care to an unlicensed assistive personnel (UAP) for a client who is prescribed habit training to manage incontinence, a nurse evaluates the UAP’s understanding. Which action indicates the UAP needs additional teaching?
- A. Toileting the client after breakfast
- B. Changing the client’s incontinence brief when wet
- C. Encouraging the client to drink fluids
- D. Recording the client’s incontinence episodes
Correct answer: B
Rationale: The correct action that indicates the UAP needs additional teaching is choice B, 'Changing the client’s incontinence brief when wet.' Habit training is a technique used to manage incontinence, and it is undermined by the use of absorbent incontinence briefs or pads. The nurse should re-educate the UAP on the technique of habit training, which involves scheduled toileting and promoting bladder control. Choices A, C, and D are appropriate actions that support the client’s care: toileting the client after meals, encouraging fluid intake, and documenting incontinence episodes are all important aspects of managing incontinence and monitoring the client's condition.
5. The patient is receiving sulfadiazine. The healthcare provider knows that this patient’s daily fluid intake should be at least which amount?
- A. 1000 mL/day
- B. 1200 mL/day
- C. 2000 mL/day
- D. 2400 mL/day
Correct answer: C
Rationale: Sulfadiazine may lead to crystalluria, a condition where crystals form in the urine. Adequate fluid intake helps prevent this adverse effect by ensuring urine is dilute enough to prevent crystal formation. The recommended daily fluid intake for a patient receiving sulfadiazine is at least 2000 mL/day. Choices A, B, and D are incorrect because they do not provide a sufficient amount of fluid intake to prevent crystalluria in patients on sulfadiazine.
